Polish social milestone chart curves

Consent is bound to the channel it was given for: approving a post on X says
nothing about Instagram. Publishing state moves from the SocialMilestone row
into SocialMilestonePost, one row per channel, where a missing row means no
consent. The dialog asks per channel, shows the text each one will publish and
keeps a separate handle for each; Instagram captions end in hashtags because a
link there is not clickable.

Also fixes three problems in the existing X path:

- A QR code already past several thresholds produced one prompt per threshold,
  and since the post quotes the current scan count, every one of them would
  have published the same number. Only the highest threshold is announced now.
- Detection ran after every unique scan and re-read the QR code's full scan
  history just to hit skipDuplicates. Known milestones are filtered first.
- A failed post stayed failed forever because the consent dialog only opens
  once. The queue now retries three times on its own, spaces first attempts by
  SOCIAL_MILESTONE_MIN_GAP_HOURS, and Settings lists every milestone per
  channel with restart and revoke.

The worker no longer renders the card itself; it downloads the image the app
renders at /s/m/<token>/og, which also serves the new square and portrait
formats. Instagram publishing stays off until SOCIAL_MILESTONE_CHANNELS and
SOCIAL_WORKER_CHANNELS both name it.

Schema changes are manual SQL, see sql/2026-08-16_*.sql. Run both before
deploying this version.

+# Blog-Ideen-Backlog qrmaster.net
+
+Erstellt: 2026-08-04 · Datenbasis: GSC-Export 2026-08-03 (1.001 Suchanfragen, letzte 3 Monate)
+
+Alle Themen unten haben **belegte Nachfrage aus deinen eigenen Impressionen** — keine Keyword-Tool-Schätzungen. Die Impressionszahl ist, was qrmaster.net in drei Monaten bereits ausgespielt bekam, fast durchgehend bei 0 Klicks, weil die Positionen zwischen 35 und 70 liegen.
+
+Nach Abzug der Marken-Suchanfragen (`qr master`, `qrmaster` etc.) und der bereits abgedeckten Themen bleiben **8.018 Impressionen über 263 Suchanfragen** ohne passenden Blogpost.
+
+---
+
+## Canonical & Zweitverwertung
+
+Du wolltest die Posts auch anderswo veröffentlichen können. Die Reihenfolge entscheidet, ob das hilft oder schadet.
+
+**Regel: qrmaster.net veröffentlicht zuerst und bleibt das Original.**
+
+1. Post auf qrmaster.net veröffentlichen. Die Blogseiten setzen bereits einen korrekten Self-Canonical (`https://www.qrmaster.net/blog/<slug>`) — geprüft, nichts zu tun.
+2. **Warten, bis Google die Seite indexiert hat.** In der Search Console unter „URL-Prüfung" nachsehen. Erst wenn die Seite im Index ist, syndizieren. Wer gleichzeitig veröffentlicht, riskiert, dass die stärkere Domain zuerst indexiert wird und als Original gilt.
+3. Dann erst auf Drittplattformen stellen, jeweils mit Canonical zurück auf qrmaster.net.
+
+| Plattform | Canonical setzen | Hinweis |
+|---|---|---|
+| DEV.to | Feld `canonical_url` im Frontmatter | Sauber unterstützt, beste Option für die technischen Posts |
+| Hashnode | Einstellung „Original article URL" | Sauber unterstützt |
+| Medium | „Import story" statt manuellem Einfügen | Setzt Canonical automatisch; manuelles Einfügen tut das **nicht** |
+| LinkedIn Artikel | Nicht möglich | Kein Canonical-Support — dort nur Auszug plus Link posten, nie den Volltext |
+| Reddit | Nicht möglich | Kein Volltext, sondern eigenständiger Beitrag mit Link |
+
+**Wichtig:** Ein Canonical ist ein Hinweis, keine Anweisung. Wenn die Kopie deutlich mehr Links bekommt, kann Google sie trotzdem bevorzugen. Deshalb Schritt 2 nicht überspringen.
+
+**Praktischer Hinweis zu den technischen Posts:** `qr-code-api-documentation`, `bulk-qr-code-generator-excel`, `custom-qr-code-design`, `qr-code-print-size-guide` und `location-qr-code` enthalten Code, Formate und Spezifikationsdetails — die funktionieren auf DEV.to. Die reinen Marketing-Posts eher nicht.
+
+---
+
+## Priorität 1 — Höchstes Volumen (Woche 1–8)
+
+### 1. Twitter/X QR Codes
+**591 Impressionen** · `twitter qr code generator` (140, Pos. 38,9), `twitter qr code` (135, Pos. 53), `qr code for twitter` (86), `how to scan twitter qr code` (43)
+Winkel: X hat den eigenen QR-Code aus der App weitgehend entfernt — genau deshalb die Suchanfragen. Erklären, wie man stattdessen einen Profil-Link-QR baut, und `how to scan twitter qr code` als eigenes H2 beantworten.
+
+### 2. Facebook QR Codes
+**609 Impressionen** · `facebook qr code generator` (113, Pos. 49,9), `qr code for facebook page free` (33), `facebook page qr code generator` (29), `code generator facebook` (45)
+Winkel: Unterscheidung Seite vs. Profil vs. Gruppe vs. Event — vier verschiedene URL-Formate, die unterschiedlich funktionieren. Achtung: `code generator facebook` meint teils Facebooks Login-Code-Generator, also andere Intention. Im Text abgrenzen.
+
+### 3. URL- und Redirect-Grundlagen
+**787 Impressionen** · `create a qr code for a url` (58), `url qr code` (53), `redirect qr code` (47), `create qr code from url` (30), `turn url into qr code` (26)
+Winkel: Der größte Cluster überhaupt und rein instruktiv. Ein sauberer Grundlagen-Post, der auf alle Spezialfälle weiterverlinkt — wird zur internen Verteilerseite.
+
+### 4. Beaconstac-Alternative
+**718 Impressionen** · `beaconstac` (96), `beaconstac qr code generator` (75), `beaconstac vs popl` (67), `beaconstac vs mobilo` (57), `blinq vs beaconstac` (42), `beaconstac alternative` (34)
+Winkel: Hohe Kaufintention. Deckt sich mit dem `/vs/`-Backlog in CLAUDE.md. Die `X vs Y`-Anfragen sind Vergleiche zwischen **Wettbewerbern untereinander** — dort taucht QR Master als dritte Option auf.
+
+### 5. Krypto- und Wallet-QR-Codes
+**441 Impressionen** · `usdt qr code generator` (85, **Pos. 13,1**), `blockchain secure qr code generator` (48), `bitcoin qr code generator` (46), `crypto qr code generator` (37), `trust wallet qr code generator` (6)
+Winkel: Rankt bereits am besten von allen ungedeckten Themen. Substanz: Adressformate je Netzwerk, warum eine falsche Netzwerkwahl Geld vernichtet, Prüfsummen. Sicherheitskritisch — sorgfältig recherchieren.
+
+### 6. PayPal- und Zahlungs-QR-Codes
+**430 Impressionen** · `paypal qr code generator` (50), `qr-code zahlungen` (50), `qr code for payment generator` (19), `create paypal qr code` (19), `all in one qr code for payment` (7)
+Winkel: PayPal.Me-Linkformat, Abgrenzung zu EPC/GiroCode im EU-Raum, was rechtlich zu beachten ist.
+
+### 7. SMS-QR-Codes
+**330 Impressionen** · `sms qr code generator` (51), `sms qr code` (48), `qr code sms generator` (27), `create sms qr code` (22)
+Winkel: Das `SMSTO:`-Format und die vorbefüllte Nachricht — technisch dieselbe Präzision wie beim WhatsApp-Post, dieselbe Fehlerquelle bei der Nummernformatierung.
+
+### 8. QR Codes für Immobilien
+**326 Impressionen** · `qr code real estate signs` (41), `qr code generator for real estate` (41), `real estate signs with qr codes` (24), `qr for real estate` (21)
+Winkel: Schilder im Freien — Größe für Lesung aus Autoentfernung, Wetterfestigkeit, dynamische Codes für Objektwechsel. Verweist auf den Print-Size-Guide.
+
+---
+
+## Priorität 2 — Mittleres Volumen (Woche 9–18)
+
+### 9. Flowcode-Alternative
+**246 Impressionen** · `flowcode alternative` (51, **Pos. 18,3**), `flowcode qr competitors` (47), `flowcode competitors` (38), `flowcode pricing` (21)
+Steht bereits auf Position 18 — kürzester Weg auf Seite 1 im Wettbewerbsumfeld.
+
+### 10. Bearbeitbare QR Codes / Ziel ändern
+**217 Impressionen** · `changeable qr code` (63), `dynamic qr code editing` (51), `editable qr code` (25), `convert static qr code to dynamic` (59)
+Winkel: Beantwortet die Frage „kann ich einen gedruckten Code noch ändern" direkt. Ehrliche Antwort: statisch nein, dynamisch ja — und was man tut, wenn schon statisch gedruckt wurde.
+
+### 11. TikTok QR Codes
+**209 Impressionen** · `tiktok qr code generator` (113, Pos. 25,4), `qr code generator tiktok` (27), `free tiktok qr code generator` (23)
+Es gibt bereits `/tools/tiktok-qr-code` (465 Impr., 9 Klicks) — der Post wäre Support-Content dafür.
+
+### 12. Zoom QR Codes
+**200 Impressionen** · `zoom qr code generator` (56, Pos. 28,8), `qr code for zoom meeting` (23), `create qr code from zoom link` (12)
+Winkel: Wie der Teams-Post — welcher Meeting-Link haltbar ist, Sicherheit bei sichtbaren Codes.
+
+### 13. YouTube QR Codes
+**196 Impressionen** · `youtube qr code generator` (67), `qr code youtube generator` (25), `youtube channel qr code generator` (14), `youtube playlist qr code` (7)
+`youtube-qr-code-guide` existiert bereits (936 Wörter, 0 Impressionen) — **prüfen statt neu schreiben**, warum er nicht ausgespielt wird.
+
+### 14. Verpackung und Produkt-QR
+**196 Impressionen** · `qr code packaging` (38), `qr codes for wine labels` (25), `qr code for wine bottle` (25), `qr code retail` (19), `qr code for product tracking` (10)
+Winkel: Gebogene Flächen, Materialeinflüsse, GS1 Digital Link als Zukunftsformat.
+
+### 15. Hotel-QR-Codes
+**159 Impressionen** · `hotel info via qr code` (63), `qr code for hotel` (23), `hotel qr code` (21), `hotel check in qr code` (5)
+Auch `system qr dla hoteli` (72, Polnisch) — Nachfrage besteht international.
+
+### 16. E-Mail-QR-Codes
+**117 Impressionen** · `qr code generator for email` (18), `qr code email generator` (18), `free email qr code generator` (12), `qr code to email` (3)
+Winkel: `mailto:`-Format mit vorbefülltem Betreff und Text, URL-Encoding — kurzer, technisch präziser Post.
+
+### 17. Café- und Gastronomie-QR
+**122 Impressionen** · `qr code cafe` (48), `cafe qr code` (25), `qr cafe` (21), `qr code holder for restaurant` (6)
+Achtung: Überschneidung mit `/restaurants`. Abgrenzen oder dorthin verlinken statt Kannibalisierung erzeugen.
+
+### 18. Flyer und Print-Kampagnen
+**118 Impressionen** · `qr codes on flyers` (58), `how to track qr code scans from a print campaign` (43, **Pos. 9,9**), `how to put qr code on flyer` (4)
+Die Print-Kampagnen-Anfrage steht schon auf Position 9,9 und ist bereits als H2 im Tracking-Guide. Ein eigener Post wäre die Vertiefung.
+
+### 19. Kalender- und Termin-QR
+**97 Impressionen** · `qr code for calendar event` (22), `free qr code generator calendar event` (13), `create qr code calendar event` (11)
+Winkel: Das iCal/VEVENT-Format direkt im Code — funktioniert offline, deshalb der stärkste Event-Anwendungsfall.
+
+---
+
+## Priorität 3 — Nischen mit klarer Intention (Woche 19–30)
+
+### 20. Kirchen, Schulen, Bibliotheken
+**77 Impressionen** · `qr for schools` (16), `qr code for church` (13), `qr code library` (10), `church donation qr code` (9), `campus qr code` (5)
+
+### 21. Gesundheitswesen, Versicherung, Kanzleien
+**50 Impressionen** · `qr code insurance industry` (18), `qr codes for legal services` (8), `qr code for dental clinics` (8), `qr codes for healthcare patient intake forms` (6)
+Winkel: Datenschutz und Einwilligung bei Patientenformularen — Thema, das andere meiden.
+
+### 22. Bitly als Alternative
+**57 Impressionen** · `bitly qr code` (16), `bitly qr code alternative` (12), `bitly vs beaconstac qr codes` (18, **Pos. 14,9**), `bit.ly qr code generator` (6)
+
+### 23. WLAN-QR-Codes
+**11 Impressionen im Export**, aber `/tools/wifi-qr-code` hat 70 Impressionen bei Position 22,4
+Winkel: Das `WIFI:`-Format, WPA vs. WPA2, Sonderzeichen im Passwort — kurzer technischer Post mit hoher Praxisrelevanz.
+
+### 24–30. Weitere belegte Einzelthemen
+- **Stadien und Veranstaltungsorte** — `qr code in sports stadium` (17, Pos. 20,2), `qr codes for stadiums` (9)
+- **Flughäfen** — `airport qr code` (10, Pos. 19,9), `qr code airport` (9)
+- **Friseure und Barbershops** — `qr barber` (13, **Pos. 8,9**), `barber business cards with qr code` (4)
+- **Fitness und Yoga** — `yoga qr code` (5), `short code for yoga studios` (7)
+- **Foodtrucks** — `food truck qr code` (3, Pos. 46)
+- **Schmuck und Inventar** — `jewelry inventory qr code solutions` (6), `bijuterii qr code` (8)
+- **Messen und Networking** — `qr codes for event networking` (7, Pos. 15), `qr codes at trade shows` (7)
+
+---
+
+## Deutscher Markt — separate Entscheidung
+
+**400 Impressionen**, alle bei 0 Klicks und Position 55–103:
+`qr code erstellen gratis` (109, Pos. 100,4), `kostenlos qr code erstellen` (66, Pos. 102,7), `qr-code zahlungen` (50), `dynamische qr-codes` (45), `qr visitenkarte` (11), `qr code visitenkarte` (9)
+
+Positionen über 100 bedeuten: Google kennt die Seiten, hält sie aber für die schlechteste verfügbare Antwort. Die 13 `/de/`-Seiten haben zusammen 194 Impressionen und **0 Klicks**.
+
+Das ist keine Content-Frage, sondern die offene Grundsatzentscheidung aus dem Umsetzungsplan: eine echte deutsche Sektion mit hreflang und eigenständigen Texten, oder deindexieren. Einzelne deutsche Blogposts ohne diese Entscheidung verschärfen das Problem nur.
+
+---
+
+## Reihenfolge-Empfehlung
+
+Nicht streng nach Impressionen gehen. Diese vier zuerst, weil sie am nächsten an Seite 1 stehen:
+
+1. **Flowcode-Alternative** — Position 18,3
+2. **Krypto/USDT** — Position 13,1
+3. **TikTok** — Position 25,4
+4. **Zoom** — Position 28,8
+
+Danach die Volumen-Themen aus Priorität 1. Ein Post auf Position 25 auf Seite 1 zu heben bringt kurzfristig mehr als ein Post auf Position 55 mit dreifachem Volumen.
+
+## Format-Vorlage
+
+Die 22 überarbeiteten Posts folgen einem Muster, das sich bewährt hat und für neue übernommen werden sollte:
+
+- Direkte Antwort im ersten Absatz, keine Einleitung über die Geschichte des QR-Codes
+- Ein konkretes Format, Feld oder Zahlenbeispiel, das man ohne Tool nachbauen kann
+- Eine Tabelle, die zwei Optionen ehrlich gegenüberstellt — inklusive der Zeile, in der die kostenlose Variante gewinnt
+- Ein Abschnitt „was schiefgeht" mit benannten Fehlermodi statt allgemeiner Tipps
+- Interne Links auf die passende Tool- oder Money-Page
+- Quellen, die keine Wettbewerber sind

+
+### Formales
+
+- [x] 729 lange Striche ersetzt, keine mehr im Quellcode
+- [x] CRLF-Zeilenenden durchgehend erhalten
+- [x] SQL-Datei aktualisiert: Block 4 ist jetzt Pflicht, nicht optional
+
+---
+
+## NICHT GEBAUT
+
+### Vor dem Deploy zwingend
+
+- [ ] **SQL ausführen** (`sql/2026-07-27_cro_retention_design.txt`), alle sechs Blöcke
+- [ ] **`npx prisma generate`** - ohne das kennt der Client `QRDesignPreset` nicht und `/api/design-presets` wirft zur Laufzeit
+- [ ] **Block 3.2** - sonst geht die Erster-Scan-Mail an die gesamte Bestandsbasis
+- [ ] Entscheidung zu Block 3.1
+
+### Nicht getestet
+
+- [ ] Kein Browser-Durchlauf. Der Renderer ist gegen einen Decoder geprüft, nicht im echten DOM
+- [ ] PNG-Download über `html-to-image` mit dem neuen SVG nicht verifiziert
+- [ ] SVG-Download nicht verifiziert
+- [ ] Logo-Overlay im neuen Renderer nicht visuell geprüft
+- [ ] Stripe-Checkout mit `returnPath` nicht live durchlaufen
+- [ ] Pausieren und Reaktivieren nicht gegen echte Daten
+- [ ] Preset speichern, laden, auf Bulk anwenden nicht gegen echte Daten
+
+### Bewusst weggelassen
+
+- [ ] Rahmen mit Label als Vektor. Die bestehenden Rahmen sind HTML um den QR herum; der SVG-Download fällt dort weiterhin auf PNG zurück und sagt es
+- [ ] Logo-Formen (Punkt, Herz, Blitz, WLAN) aus der Showcase
+- [ ] Eye-Frames circle, leaf, flower, hexagon - Messergebnis 0/15
+- [ ] star als Eye-Ball - 3/5
+
+### Offene inhaltliche Frage
+
+- [ ] Tag-30-Mail: gab es die Gespräche mit Pro-Nutzern über Branding? Bei Ja gehört ein wörtliches Zitat rein
+
+### Vorbehalt zur Messung
+
+Getestet wurde mit OpenCVs Decoder. Der ist strenger als iPhone- und Android-Kameras. Es ist möglich, dass ein Kreis-Eye-Frame auf echten Geräten funktioniert - aber 0 von 15 ist kein Rauschen, und das ist nichts, was man ungetestet auf Druckmaterial loslässt.

+## AI SEO / AEO Tracking (AI Answer Engine Visibility)
+
+Ongoing effort to increase QR Master's presence in AI-generated answers (ChatGPT, Perplexity, AI Overviews, etc.) for QR-code-generator-related queries. Update this section after each audit/build cycle so future sessions build on prior findings instead of re-deriving them.
+
+### Baseline audit (2026-07-22)
+
+Query-fanout data (what an AI model searches for while answering a prompt) showed QR Master already being cited in AI-generated answers for 3 of 9 tested query themes: "best QR code generator for marketing campaigns", "QR code generator with analytics and tracking", and "affordable dynamic QR code generator for small business" — positioned as the budget/SMB pick alongside Uniqode, QR TIGER, Bitly, Flowcode, and Hovercode.
+
+No QR Master citation appeared for: "best dynamic QR code generator 2026", "best QR code generator for businesses", "best QR code generator for agencies", "alternatives to QR TIGER", "QR code generator with unlimited scans", "free dynamic QR code generator unlimited scans".
+
+Existing on-site AEO infrastructure found during the audit:
+- `public/llms.txt` present — lists core pages and cornerstone guides for AI retrieval
+- `/alternatives/` pages exist only for: qr-code-generator.com, Flowcode, Beaconstac, Bitly
+- `/vs/` pages exist only for: Beaconstac
+- `/compare/[slug]` dynamic comparison route exists (e.g. `free-vs-paid-qr-code-generator`)
+- Blog cornerstones: best-qr-code-generator-2026, free-vs-paid-qr-generator, qr-code-tracking-guide-2025, dynamic-vs-static-qr-codes, qr-code-small-business, qr-code-scan-statistics-2026, etc.
+
+Pattern observed: QR Master gets cited by AI models only where first-party comparison/guide content already exists on the domain. The fanout queries repeatedly run `site:` searches against Uniqode, QR TIGER (qrcode-tiger.com), Hovercode, Scanova, and QRCodeChimp — none of which currently have a matching QR Master alternatives/vs page.
+
+### Priority backlog (from this audit)
+1. Build `/alternatives/uniqode`, `/alternatives/qr-code-tiger`, `/alternatives/hovercode` (highest fanout frequency, in that order)
+2. Build matching `/vs/uniqode`, `/vs/qr-code-tiger`, `/vs/hovercode` (same format as `/vs/beaconstac`)
+3. New cornerstone guide: "QR code generator for agencies" (white-label, bulk creation, API) — zero QR Master positioning currently exists for this query cluster
+4. Update `public/llms.txt` once the new pages ship, so they enter the AI retrieval list
+5. Re-run the same query-fanout test periodically to track citation-rate changes over time
+
+### Additional confirmed win — "dynamic barcode generator" (2026-07-22, same session)
+
+Tested outside the original 9-theme set. QR Master is cited as the "Best overall option" for this query — credited for trackable/editable dynamic barcodes, bulk generation, unified analytics, and UTM tracking, plus static EAN-13/UPC-A/Code 128 support when editability isn't needed. The AI answer also included a "requirement → recommended format" decision table (dynamic QR vs. EAN-13/UPC-A vs. Code 128 vs. GS1 Digital Link) that maps closely to existing on-site content.
+
+This maps to the `/tools/barcode-generator` tool, reinforcing the pattern above: dedicated first-party pages targeting a query cluster get cited, gaps without dedicated pages don't. Counts as a 4th confirmed positive theme alongside the original 3 from the baseline audit.
+
+Note: `/dynamic-barcode-generator` and `/barcode-generator` are **not** live pages — both 301 to `/tools/barcode-generator` (see `redirects()` in `next.config.mjs`). Cite the canonical `/tools/barcode-generator` URL in any AEO work.
+
+### Sitemap / IndexNow drift (fixed 2026-08-13)
+
+`src/app/sitemap.ts` and `getAllIndexableUrls()` in `src/lib/indexnow.ts` are two hand-maintained URL lists that had silently diverged: the whole `/alternatives/*` + `/vs/*` cluster (1,942 GSC impressions in the 3 months to 2026-08-13, avg pos ~29-47) was submitted to IndexNow and linked from the footer but missing from the sitemap, while `/dynamic-barcode-generator` was listed in both despite 301-ing.
+
+**When adding or redirecting a marketing page, update both lists.** A redirected URL must appear in neither.
+
+### Google Review cluster — biggest non-brand opportunity (2026-08-13)
+
+`/tools/google-review-qr-code` is the **#2 page on the site by impressions** (2,201 in 3 months) and converts almost none of it: 2 clicks, avg position 33. The query cluster is ~1,667 impressions across 50+ queries, all at position 20-50, zero clicks. Head term `google review qr code generator` = 268 impr at pos 35.
+
+**On-page is not the constraint — do not "improve the content".** Audited 2026-08-13: it is already the deepest tool page on the site (1,352 rendered words, 8 h2 / 18 h3 vs 549 for crypto, 741 for wifi), with SoftwareApplication + HowTo + FAQPage schema, a correctly matched title, and canonical set. It also does not meaningfully cannibalize `/use-cases/qr-codes-for-review-collection` (36 impr, pos 11), which targets the tracking angle.
+
+What was done: added `google-review-qr-code` to `toolsMap` in `qr-code-for/[industry]/page.tsx` and to the `tools[]` array of the 32 local-business industries in `src/lib/industry-pages.ts`, creating contextual internal links from crawled, well-ranking pages (barbershops pos 9.7, hotels, cafes, bars). The 20 institutional industries (airports, schools, stadiums, libraries, churches, universities, museums, theaters, cinemas, art-galleries, events, trade-shows, retail, and the non-local stores) were deliberately excluded — review collection is not their job, and blanket-linking all 52 would be boilerplate.
+
+Remaining gap is off-site authority, not anything in this repo. Note the fallback in that template silently rewrites an unknown tool slug to `/tools/url-qr-code`, so any new slug must be added to `toolsMap` or the link disappears without erroring.

+# SERP-CTR Rewrite — 27. Juli 2026
+
+Grundlage: GSC-Export 28 Tage (8.944 Impressionen, 52 Klicks, 0,58% CTR, Ø-Position 33,0)
+Methodik: `direct-response-copywriting` + Positioning Decision vom 26.07.2026 (Direction 1 als Positionierung, Direction 2 als Proof-Layer)
+
+## Ehrliche Einordnung des 5–10%-Ziels
+
+Site-weite CTR von 5–10% ist bei Ø-Position 33 **nicht durch Copy erreichbar**. CTR ist primär eine Funktion der Position:
+
+| Position | Erwartete CTR |
+|---|---|
+| 1 | 28–40% |
+| 3 | 10–11% |
+| 5 | 5–6% |
+| 10 | 2–3% |
+| 15 | 1–2% |
+| 30+ | <0,3% |
+
+Die zwei größten Impression-Seiten (`/dynamic-qr-code-generator` 1.694 Imp @ Pos 33,5 und `/qr-code-tracking` 1.023 Imp @ Pos 34,0) haben 0% CTR. Das ist bei Position 33 **normal** — 31% aller Impressionen der Site liegen auf Seite 4 der SERP. Kein Title der Welt repariert das; das ist ein Ranking-Thema.
+
+**Was Copy realistisch leisten kann:**
+- Seiten auf Pos 1–15 auf ihren Positions-Benchmark heben → aus 52 Klicks werden ca. 90–120
+- Die großen Volumenseiten so vorbereiten, dass sie beim Aufstieg auf Seite 1 sofort auf Benchmark klicken statt bei 2%
+
+5–10% site-weit wird erst realistisch, wenn die Ø-Position unter ~10 liegt. Dann trägt diese Copy den Unterschied.
+
+## Die drei strukturellen Fehler, die behoben wurden
+
+**1. Deutsche Halbsätze in englischen Descriptions.** 97% der Impressionen kommen aus USA/Indien/englischsprachigen Märkten. Trotzdem stand in den Tool-Descriptions „Teams QR Code erstellen", „Zoom QR Code erstellen", „TikTok QR Code erstellen", „Erstelle Bitcoin & Ethereum QR Codes", „Standort teilen leicht gemacht". Für einen englischen Sucher liest sich das wie maschinell übersetzter Spam. Das ist die wahrscheinlichste Ursache für 0,61% CTR auf Pos 10 (`barbershops`) und 0,65% auf Pos 17 (`zoom`).
+
+**2. `| QR Master`-Suffix und 65+ Zeichen lange Titles.** Google schneidet bei ~580px ab. `Free Microsoft Teams QR Code Generator | Join Meetings | QR Master` (66 Zeichen) wurde in der SERP abgeschnitten — der Nutzen verschwand im „…". Alle neuen Titles liegen bei 42–55 Zeichen.
+
+**3. Null Pattern Interruption.** Jedes Ergebnis in dieser SERP sagt „Free QR Code Generator". Die alten Descriptions sagten „Instant and free", „Free & Easy" — die vagesten möglichen Claims. Neu: konkrete, falsifizierbare Spezifika (3 dynamische Codes gratis, 1.000 Codes aus einem Spreadsheet, 42 Zeichen Wallet-Adresse, EAN-13/UPC-A/Code 128).
+
+## Wichtigste Änderungen
+
+| Seite | Imp | CTR | Pos | Kernänderung |
+|---|---|---|---|---|
+| `/` | 1.046 | 4,88% | 4,6 | Title: Mechanismus statt Kategorie. Description: 3 verifizierte Zahlen statt Feature-Liste. H1: „The Link Doesn't Have to Stay Wrong Once It's Printed" |
+| `/qr-code-tracking` | 1.023 | 0% | 34,0 | Title war „QR Code Tracking: Track QR Code Scans" — redundant, kein Nutzenversprechen. Neu: „See Which Placement Drove the Scan" (= Main-Headline-Idee aus Offer Brief §14) |
+| `/dynamic-qr-code-generator` | 1.694 | 0% | 33,5 | Title war schon gut, blieb. Description auf Schmerz + Zahlen umgestellt |
+| `/tools/google-review-qr-code` | 566 | 0,18% | 24,8 | Description führt jetzt mit dem Moment: „while the customer is still standing there" |
+| `/tools/teams-qr-code` | 277 | 3,25% | 9,6 | Title von 66 auf 48 Zeichen, Deutsch raus |
+| `/qr-code-for/barbershops` | 163 | 0,61% | 10,0 | metaTitle war 68 Zeichen → Fallback griff auf generisches „QR Codes for Barbershops \| QR Master". Jetzt 44 Zeichen mit Nutzen |
+| `/learn` | 226 | 0,88% | 11,3 | Zielt auf „qr mastery" (130 Imp @ Pos 5,1). Description führt jetzt mit den Problemen statt mit „Learning Hub" |
+| `/bulk-qr-code-generator` | 296 | 2,36% | 23,1 | Description nennt offen „Output is static — not dynamic or trackable" (Belief 5 / Proof-Layer) |
+
+Zusätzlich überarbeitet: crypto, facebook, url, vcard, instagram, tiktok, twitter, zoom, geolocation, barcode-generator, custom-qr-code-generator, alternatives/beaconstac, blog/microsoft-teams-qr-code.
+
+## Zwei Korrekturen an bestehenden Claims
+
+- **`/alternatives/beaconstac`**: Erster Entwurf enthielt „Not €99+" über Uniqode. Der Offer Brief verifiziert Uniqodes Preis **nicht** (nur „G2-Muster: teuer für kleine Teams"). Behauptung entfernt — genannt werden nur die eigenen, verifizierten Preise €0/€9/€29.
+- **Pricing-Card**: „Bulk QR Creation (up to 1,000)" → „(up to 1,000, static output)" in `en.json`. Das war Immediate Next Action #1 aus dem Offer Brief (A2) und die größte Transparenz-Lücke auf der Seite.
+
+## Was als Nächstes mehr bringt als weitere Copy
+
+1. **Ranking, nicht CTR.** 31% der Impressionen liegen auf Position 30+. Der Hebel dort ist Content/Links, nicht der Title.
+2. **Die Kündigungs-Policy (Offer Brief A3).** ToS §4 sagt „may affect the availability of dynamic QR codes". Für genau diese Zielgruppe ist das das Erkennungszeichen der schlechten Anbieter. Blockiert den gesamten Proof-Layer.
+3. **10–15 unabhängige Reviews auf G2/Capterra.** Laut Offer Brief §8 höher priorisiert als jede Copy-Iteration.
+
+## Messung
+
+In 4 Wochen im GSC vergleichen — **pro Seite und positionsbereinigt**, nicht site-weit:
+
+- `/` — Ziel 7–9% (von 4,88%, bei stabiler Pos ~4,6)
+- `/learn` — Ziel 1,8–2,5% (von 0,88%)
+- `/qr-code-for/barbershops` — Ziel 2,0–2,5% (von 0,61%)
+- `/tools/zoom-qr-code` — Ziel 1,2% (von 0,65%)
+- `/tools/teams-qr-code` — Ziel 4–5% (von 3,25%)
+
+Wenn die Position sich gleichzeitig verändert, ist der Vergleich der Rohwerte wertlos — dann `gsc-ctr-by-position` verwenden.

+# Anleitung: Testumgebung testmodul.qrmaster.net aufsetzen
+
+Diese Anleitung richtet auf dem Produktionsserver eine **zweite, getrennte Instanz** von
+QR Master ein, erreichbar unter `testmodul.qrmaster.net`. Sie läuft auf dem Branch `test`
+mit einer eigenen, leeren Datenbank.
+
+Die laufende Produktion wird dabei **nicht angefasst**. Alle Schritte hier legen neue
+Container, ein neues Volume und ein neues Verzeichnis an.
+
+## Kurzfassung zum Abhaken
+
+Wer die Begründungen nicht braucht, arbeitet diese Liste ab. Die ausführlichen Abschnitte
+darunter erklären jeden Schritt und was schiefgehen kann.
+
+- [ ] **1.** Repo klonen, Branch `test`, **eigenes Verzeichnis** neben der Produktion
+- [ ] **2.** `.env.test` von Timo dort ablegen und die vier Kernwerte prüfen
+- [ ] **3.** Stack bauen und starten (`-p qrmaster-test`)
+- [ ] **4.** Schema aus Prod dumpen und einspielen - **kein** `prisma migrate`
+- [ ] **5.** Testaccount per SQL anlegen (Registrierungsformular funktioniert nicht)
+- [ ] **6.** Caddy-Block ergänzen und neu laden
+- [ ] **7.** Abnahme: DB-Trennung, keine Migrationen, robots.txt, Browser-Test
+
+### Alle Befehle am Stück
+
+```bash
+# 1 - Checkout (NICHT im Produktionsverzeichnis)
+git clone -b test https://git.bizmatch.net/tknuth/QR-master.git qrmaster-test
+cd qrmaster-test
+git branch --show-current          # muss "test" zeigen
+
+# 2 - .env.test hier ablegen, dann pruefen
+grep -E "NEXT_PUBLIC_WWW_URL|NEXT_PUBLIC_APP_URL|AUTH_COOKIE_NAME|POSTGRES_DB" .env.test
+# Erwartet: beide URLs auf testmodul, AUTH_COOKIE_NAME=userId_test,
+# POSTGRES_DB=qrmaster_test. Steht dort app./www. -> STOPP, siehe Schritt 2.
+
+# 3 - Stack starten
+docker compose -p qrmaster-test --env-file .env.test \
+  -f docker-compose.yml -f docker-compose.test.yml up -d --build
+docker ps --filter "name=qrmaster-test" --format "table {{.Names}}\t{{.Status}}"
+
+# 4 - Schema (nur Struktur, keine Kundendaten)
+docker exec qrmaster-db pg_dump -U postgres --schema-only qrmaster > schema.sql
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test < schema.sql
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c "\dt" | head -20
+
+# 5 - Testaccount: erst Hash erzeugen, dann in den INSERT einsetzen
+docker exec qrmaster-test-web node -e "console.log(require('bcryptjs').hashSync('DEIN_TESTPASSWORT',12))"
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test -c "INSERT INTO \"User\" (id,email,name,password,\"emailVerified\",\"updatedAt\") VALUES ('testuser1','test@qrmaster.net','Test','HIER_DER_HASH',now(),now());"
+
+# 6 - Caddy: Block ergaenzen (siehe Schritt 6), dann
+caddy reload --config /etc/caddy/Caddyfile
+
+# 7 - Abnahme
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c 'SELECT count(*) FROM "User";'
+docker exec qrmaster-db psql -U postgres -d qrmaster -c 'SELECT count(*) FROM "User";'
+docker logs qrmaster-test-web 2>&1 | head -20
+curl -s https://testmodul.qrmaster.net/robots.txt
+```
+
+Die beiden `count(*)` müssen sich unterscheiden, in den Logs darf kein "Applying Prisma
+migrations" stehen, und `robots.txt` muss `Disallow: /` liefern.
+
+## Voraussetzungen
+
+- SSH-Zugang zum Server, auf dem QR Master läuft
+- Docker und Docker Compose (mindestens v2.24 - wird für `!override` und `!reset` gebraucht;
+  prüfen mit `docker compose version`)
+- Schreibrechte auf die Caddy-Konfiguration
+- Die Datei **`.env.test`** - die kommt von Timo und ist nicht im Repository, weil sie
+  Passwörter enthält
+- Der DNS-Eintrag `testmodul.qrmaster.net` existiert bereits (CNAME)
+
+## Was NICHT angefasst wird
+
+- Das bestehende Produktionsverzeichnis: dort **nicht** den Branch wechseln. Ein späterer
+  Prod-Rebuild würde sonst Testcode bauen.
+- Die Produktions-`.env`
+- Die bestehenden Caddy-Blöcke für `www.qrmaster.net`, `app.qrmaster.net` und `qrmaster.net`
+- Die Produktionsdatenbank. Der einzige Zugriff darauf ist ein `pg_dump --schema-only`,
+  das ausschließlich liest.
+
+---
+
+## 1. Zweites Checkout anlegen
+
+**Nicht** im Produktionsverzeichnis arbeiten. Ein eigenes Verzeichnis daneben, z.B. im
+selben übergeordneten Ordner:
+
+```bash
+git clone -b test https://git.bizmatch.net/tknuth/QR-master.git qrmaster-test
+```
+
+Danach in dieses Verzeichnis wechseln. **Alle weiteren Befehle laufen von dort**, sofern
+nicht anders angegeben.
+
+```bash
+cd qrmaster-test
+```
+
+Prüfen, dass der richtige Branch ausgecheckt ist - es muss `test` erscheinen:
+
+```bash
+git branch --show-current
+```
+
+## 2. `.env.test` ablegen
+
+Die von Timo erhaltene Datei als `.env.test` in dieses Verzeichnis legen (also
+`qrmaster-test/.env.test`).
+
+Kurz gegenprüfen, dass die vier wichtigsten Werte stimmen:
+
+```bash
+grep -E "NEXT_PUBLIC_WWW_URL|NEXT_PUBLIC_APP_URL|AUTH_COOKIE_NAME|POSTGRES_DB" .env.test
+```
+
+Erwartet:
+
+```
+NEXT_PUBLIC_WWW_URL=https://testmodul.qrmaster.net
+NEXT_PUBLIC_APP_URL=https://testmodul.qrmaster.net
+AUTH_COOKIE_NAME=userId_test
+POSTGRES_DB=qrmaster_test
+```
+
+Steht bei einer der URLs `app.qrmaster.net` oder `www.qrmaster.net`, **nicht starten** -
+dann würden Klicks in der Testumgebung in die Produktion umleiten.
+
+## 3. Stack bauen und starten
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml up -d --build
+```
+
+Der erste Build dauert einige Minuten. Der Projektname `-p qrmaster-test` ist wichtig: er
+sorgt dafür, dass eigene Container und ein eigenes Volume entstehen und nichts aus der
+Produktion überschrieben wird.
+
+Läuft alles, sollten drei neue Container existieren:
+
+```bash
+docker ps --filter "name=qrmaster-test" --format "table {{.Names}}\t{{.Status}}"
+```
+
+Erwartet: `qrmaster-test-db`, `qrmaster-test-redis`, `qrmaster-test-web`.
+
+Die Anwendung kann zu diesem Zeitpunkt noch nichts anzeigen - die Datenbank ist leer. Das
+ist normal und wird im nächsten Schritt behoben.
+
+## 4. Datenbankschema einspielen
+
+Die Testdatenbank bekommt **nur die Struktur** aus der Produktion, keine Daten. Es werden
+also keine Kundendaten kopiert.
+
+Struktur aus der Produktionsdatenbank exportieren (reiner Lesezugriff):
+
+```bash
+docker exec qrmaster-db pg_dump -U postgres --schema-only qrmaster > schema.sql
+```
+
+In die Testdatenbank einspielen:
+
+```bash
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test < schema.sql
+```
+
+> **Wichtig:** Nicht `prisma migrate` verwenden. Die Migrationsdateien im Repository sind
+> seit April 2026 nicht mehr gepflegt - alle Schemaänderungen seitdem wurden per SQL
+> gemacht. Ein `migrate deploy` würde ein veraltetes Schema erzeugen, mit dem die
+> Anwendung nicht läuft. Der Container startet deshalb bewusst ohne Migrationsschritt.
+
+Prüfen, dass Tabellen angekommen sind:
+
+```bash
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c "\dt" | head -20
+```
+
+## 5. Testaccount anlegen
+
+Die Registrierung über das Formular funktioniert hier **nicht**: die Testumgebung
+verschickt bewusst keine E-Mails, und ohne Bestätigungsmail wird der Account vom System
+wieder gelöscht. Der Account wird deshalb direkt in der Datenbank angelegt.
+
+Zuerst einen Passwort-Hash erzeugen (`DEIN_TESTPASSWORT` durch ein selbst gewähltes
+Passwort ersetzen):
+
+```bash
+docker exec qrmaster-test-web node -e "console.log(require('bcryptjs').hashSync('DEIN_TESTPASSWORT',12))"
+```
+
+Die Ausgabe ist eine Zeichenkette, die mit `$2a$12$` oder `$2b$12$` beginnt. Diese im
+folgenden Befehl anstelle von `HIER_DER_HASH` einsetzen:
+
+```bash
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test -c "INSERT INTO \"User\" (id,email,name,password,\"emailVerified\",\"updatedAt\") VALUES ('testuser1','test@qrmaster.net','Test','HIER_DER_HASH',now(),now());"
+```
+
+Anmeldung erfolgt danach ganz normal über `/login` mit `test@qrmaster.net` und dem
+gewählten Passwort.
+
+## 6. Caddy konfigurieren
+
+Einen neuen Block in die Caddy-Konfiguration aufnehmen (Pfad ggf. anpassen). Die
+bestehenden Blöcke bleiben unverändert:
+
+```caddyfile
+testmodul.qrmaster.net {
+    reverse_proxy qrmaster-test-web:3000
+}
+```
+
+Konfiguration neu laden:
+
+```bash
+caddy reload --config /etc/caddy/Caddyfile
+```
+
+Caddy holt das TLS-Zertifikat automatisch. Das kann eine Minute dauern.
+
+## 7. Abnahme
+
+**a) Datenbanken sind getrennt.** Die beiden Zahlen müssen sich unterscheiden - die
+Testdatenbank enthält nur den eben angelegten Account:
+
+```bash
+docker exec qrmaster-test-db psql -U postgres -d qrmaster_test -c 'SELECT count(*) FROM "User";'
+```
+
+```bash
+docker exec qrmaster-db psql -U postgres -d qrmaster -c 'SELECT count(*) FROM "User";'
+```
+
+**b) Keine Migrationen gelaufen.** In der Ausgabe darf **nicht** "Applying Prisma
+migrations" stehen:
+
+```bash
+docker logs qrmaster-test-web 2>&1 | head -20
+```
+
+**c) Suchmaschinen ausgesperrt.** Muss `Disallow: /` liefern:
+
+```bash
+curl -s https://testmodul.qrmaster.net/robots.txt
+```
+
+**d) Im Browser:**
+
+- `https://testmodul.qrmaster.net` lädt mit gültigem Zertifikat
+- Anmeldung mit dem Testaccount funktioniert
+- `https://testmodul.qrmaster.net/dashboard` **bleibt auf testmodul** und springt nicht auf
+  `app.qrmaster.net`. Passiert das doch, sind die URLs in der `.env.test` falsch.
+- In den Entwicklertools unter Application → Cookies liegen zwei getrennte Cookies:
+  `userId` mit Domain `.qrmaster.net` (Produktion) und `userId_test` mit Domain
+  `testmodul.qrmaster.net`
+- Die Produktion ist weiterhin erreichbar und man ist dort weiterhin angemeldet
+
+---
+
+## Laufender Betrieb
+
+Neuen Stand deployen, nachdem auf dem Branch `test` etwas gepusht wurde - aus dem
+Verzeichnis `qrmaster-test`:
+
+```bash
+git pull
+```
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml up -d --build
+```
+
+Ein Rebuild ist **immer** nötig, ein bloßer Neustart genügt nicht: die Host-URLs und der
+Cookie-Name werden beim Bauen fest in die Anwendung kompiliert.
+
+Schemaänderungen werden weiterhin **von Hand per SQL** ausgeführt - erst auf Test, nach
+erfolgreicher Prüfung dasselbe Statement auf Produktion. Es gibt keinen automatischen Weg
+dazwischen.
+
+## Testumgebung stoppen oder entfernen
+
+Stoppen, Daten bleiben erhalten:
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml down
+```
+
+Vollständig entfernen inklusive Testdatenbank - der Projektname `-p qrmaster-test` sorgt
+dafür, dass ausschließlich die Test-Volumes gelöscht werden:
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test -f docker-compose.yml -f docker-compose.test.yml down -v
+```
+
+## Wenn etwas nicht funktioniert
+
+| Symptom | Ursache |
+|---|---|
+| Build bricht ab mit `set AUTH_COOKIE_NAME in .env.test` | `.env.test` fehlt oder liegt im falschen Verzeichnis |
+| `qrmaster-test-db` bleibt `unhealthy`, `web` startet nicht | In der `.env.test` steht nicht `POSTGRES_DB=qrmaster_test` |
+| Caddy liefert 502 | Containername im Caddy-Block stimmt nicht, oder der Container läuft nicht - mit `docker ps` prüfen |
+| Anwendung meldet `column ... does not exist` | Schema-Import aus Schritt 4 war unvollständig - erneut einspielen |
+| `/dashboard` springt auf `app.qrmaster.net` | Die URLs in der `.env.test` zeigen nicht auf testmodul. Korrigieren und **neu bauen**, nicht nur neu starten. |
+| Anmeldung wirkt zufällig abgelaufen | `AUTH_COOKIE_NAME` ist nicht gesetzt oder steht auf `userId` - dann kollidiert es mit dem Produktions-Cookie |
+| Registrierung über das Formular schlägt fehl | Erwartet - die Testumgebung verschickt keine E-Mails. Account per SQL anlegen, Schritt 5. |
+
+## Bekannte Einschränkungen der Testumgebung
+
+Bewusst deaktiviert, weil die Umgebung nach außen nichts auslösen soll:
+
+- **Kein E-Mail-Versand** - Registrierung, Passwort-Reset und Benachrichtigungen funktionieren nicht
+- **Kein Google-Login** - Zugangsdaten sind nicht hinterlegt
+- **Keine Datei-Uploads** - der Objektspeicher (R2) ist nicht konfiguriert
+- **Kein Stripe** - Checkout und Abo-Verwaltung funktionieren nicht, solange keine Testschlüssel eingetragen sind
+- **Keine Analytics** - damit die Produktionszahlen nicht verfälscht werden

+Stand: 2026-08-12 · Ziel: die eingeloggte App liegt auf `app.qrmaster.net`, Marketing/SEO bleibt auf `www.qrmaster.net`.
+
+## Status
+
+| Schritt | Stand |
+|---|---|
+| B1 Cookie-Domain | committed + gepusht (`35ea8cc`) |
+| B2–B7 | Code fertig, typecheck + Production-Build grün, **noch nicht deployt** |
+| A4 Google Console | erledigt (beide Redirect-URIs eingetragen) |
+| A1 DNS, A2 Caddy, A3 .env, A6 Deploy | offen bei Timo |
+
+Deploy-Reihenfolge unverändert: B1 zuerst allein live und einen Tag beobachten, dann B2–B7.
+
+Neu gegenüber dem ursprünglichen Plan: `src/lib/hosts.ts` ist die einzige Quelle der Wahrheit
+für die Host-Grenze (`APP_PATH_PREFIXES`, `isAppPath`, `wwwUrl`, `appUrl`, `urlForPath`).
+Middleware, Stripe-Rückkehr-URLs und E-Mail-Links lesen alle daraus, damit sie nicht
+auseinanderdriften.
+
+## Zielarchitektur
+
+**Ein Docker-Image, ein Container, zwei Hostnames.** Caddy routet `www.qrmaster.net` und
+`app.qrmaster.net` auf denselben Upstream. Die Middleware macht Host-basiertes Routing.
+
+**Wichtig: keine Datei zieht um.** Die Next-App serviert auf beiden Hosts weiterhin alle Routen.
+`src/middleware.ts` entscheidet pro Host, welcher Pfad ausgeliefert wird, und 301t den Rest auf den
+jeweils anderen Host. Damit bleiben alle relativen Links (`router.push('/dashboard')`,
+`<Link href="/settings">`) unverändert korrekt, weil sie innerhalb desselben Hosts aufgelöst werden.
+
+```
+qrmaster.net        --301-->  www.qrmaster.net              (bleibt wie heute)
+www.qrmaster.net    ->  Marketing, /login, /signup, /r/*, /api/*
+app.qrmaster.net    ->  /dashboard /create /analytics /settings /bulk-creation
+                        /integrations /qr/* /upgrade /onboarding, /api/*
+```
+
+## Fixierte Entscheidungen
+
+| Frage | Entscheidung | Begründung |
+|---|---|---|
+| Hosting | Docker + Caddy auf eigenem Server | Bestand |
+| `/login`, `/signup` | **bleiben auf www** | Alle 82 Marketing-CTAs zeigen auf `/signup`, `/signup` hat ein hartes Canonical auf www und trägt Ad-Traffic. Umzug wäre teuer ohne Nutzen. |
+| `/onboarding` | zieht auf app | Reiner Logged-in-Flow, kein SEO-Wert |
+| Host-Wechsel | genau **einmal**, nach erfolgreichem Login/Signup | einzige Cross-Host-Stelle im ganzen Flow |
+| DB | keine Änderung | — |
+
+## Teil A — Deine Aufgaben (Timo)
+
+Reihenfolge beachten: A1–A2 **vor** dem Deploy von Schritt B5, sonst zeigt die Subdomain ins Leere.
+
+### A1. DNS
+CNAME `app` → auf denselben Zielhost wie `www` (bzw. A-Record auf dieselbe Server-IP).
+Kein Proxy-Only-Sonderfall nötig, Caddy holt das Cert selbst.
+
+### A2. Caddyfile auf dem Server
+`app.qrmaster.net` in den bestehenden Site-Block aufnehmen, damit Caddy automatisch ein
+Let's-Encrypt-Cert zieht:
+
+```caddyfile
+www.qrmaster.net, app.qrmaster.net {
+    reverse_proxy qrmaster-web:3000
+}
+```
+
+Danach `caddy reload`. Prüfen: `curl -sI https://app.qrmaster.net` muss 200 oder 301 liefern,
+kein TLS-Fehler.
+
+### A3. `.env` auf dem Server ergänzen
+Zwei Variablen statt einer. Die Trennung ist der Kern des ganzen Umbaus:
+
+Für **Deploy 1** reicht:
+
+```dotenv
+COOKIE_DOMAIN=.qrmaster.net
+```
+
+Für **Deploy 2** kommen dazu:
+
+```dotenv
+NEXT_PUBLIC_WWW_URL=https://www.qrmaster.net
+NEXT_PUBLIC_APP_URL=https://app.qrmaster.net
+```
+
+`NEXT_PUBLIC_APP_URL` erst zu Deploy 2 umstellen - vorher zeigt es auf www und muss dort
+bleiben. Fehlen die Werte, greifen die Produktions-Fallbacks in `src/lib/hosts.ts`; ein
+localhost-Wert kann damit nicht in gedruckte QR-Codes gelangen.
+
+`NEXTAUTH_URL` bleibt `https://www.qrmaster.net` (wird nur noch von
+`api/social-assets/route.ts` gelesen, kein Auth-Bezug mehr).
+
+### A4. Google Cloud Console
+Bei den OAuth-Credentials als **Authorized redirect URI** zusätzlich eintragen:
+
+```
+https://app.qrmaster.net/api/auth/google
+```
+
+Die alte www-URI **nicht löschen** – sie wird während der Übergangszeit noch von
+Sessions genutzt, die den Flow auf www gestartet haben.
+
+### A5. Nichts zu tun bei Stripe und TikTok
+- Stripe-Webhook zeigt auf `www.qrmaster.net/api/stripe/webhook` und bleibt gültig
+  (`/api/*` wird auf beiden Hosts weiter bedient, siehe B5).
+- TikTok `redirect_uri` bleibt auf `qrmaster.net` – verifizierte Domain, nicht anfassen.
+
+### A6. Deploy
+`npm run docker:prod` (Rebuild ist zwingend – `NEXT_PUBLIC_*` wird zur Build-Zeit ins
+Client-Bundle inlined, ein reiner Container-Restart genügt **nicht**).
+
+## Teil B — Meine Aufgaben (Code), in Diff-Reihenfolge
+
+### B1. Cookie-Domain teilen — muss zuerst live sein
+Ohne das ist auf `app.qrmaster.net` jeder ausgeloggt: das `userId`-Cookie ist heute host-only.
+
+- `src/lib/cookieConfig.ts:11` — `getAuthCookieOptions()`: `domain: process.env.COOKIE_DOMAIN` in Prod, in Dev `undefined` (localhost verträgt keine Punkt-Domain)
+- `src/lib/cookieConfig.ts:24` — `getCsrfCookieOptions()`: dito
+- `src/middleware.ts:34` — Attribution-Cookie: dito
+- `src/app/(main)/api/auth/logout/route.ts:7` — **kritisch**: löscht heute host-only. Nach der
+  Umstellung existieren bei Bestandsnutzern beide Varianten (alt host-only + neu domain-scoped).
+  Logout muss **beide** überschreiben, sonst bleibt ein Zombie-Cookie und der Nutzer ist nicht
+  wirklich ausgeloggt. Gilt für `userId`, `newsletter-admin` und das Attribution-Cookie.
+- `src/app/(main)/api/auth/google/route.ts:53,62` — OAuth-State + Post-Auth-Redirect-Cookie
+
+Kein Forced-Logout nötig: beide Cookie-Varianten tragen denselben signierten Wert, der Server
+akzeptiert jede. `verifySignedUserIdEdge` prüft die Signatur, das Teilen über eigene Subdomains
+ist unkritisch.
+
+**Dieser Schritt kann allein auf www deployt werden, bevor die Subdomain existiert** — nach außen
+unsichtbar, und wenn app.* dann live geht, funktionieren Sessions sofort.
+
+### B2. `NEXT_PUBLIC_APP_URL` entflechten
+Die Variable bedient heute App- **und** öffentliche URLs. Jede Fundstelle einzeln zuordnen:
+
+**Muss auf `WWW_URL` (öffentlich, teils in QR-Codes kodiert):**
+- `src/components/dashboard/QRCodeCard.tsx:82` — **höchstes Risiko im ganzen Umbau**: Basis für
+  die in den QR-Code kodierte `/r/<slug>`-URL. Bleibt das auf `APP_URL`, zeigen alle neu
+  heruntergeladenen und gedruckten Codes auf die Subdomain.
+- `src/app/(main)/r/[slug]/route.ts:50,61,84,89` — Landing-Basis vcard/text/coupon/feedback
+- `src/lib/email.ts:56,562`, `src/lib/marketingEmail.ts:30` — Mail-Links auf Marketing-Inhalte
+- `src/app/(main)/api/auth/signup/route.ts:20` — Verify-Mail-Link
+- `src/app/(main)/api/stripe/checkout/route.ts:64` — `cancel_url` → `/pricing`
+- `src/lib/metaConversions.ts:44`, `src/app/(main)/api/auth/signup/route.ts:150` — Event-Source-URLs
+
+**Bleibt/wird `APP_URL` (eingeloggt):**
+- `src/app/(main)/api/stripe/checkout/route.ts:63` — `success_url` → `/dashboard`
+- `src/app/(main)/api/stripe/create-checkout-session/route.ts:112,128` — `appUrl` + returnPath
+- `src/app/(main)/api/stripe/portal/route.ts:59` — `return_url` → `/settings`
+- `src/lib/email.ts:505` — hartcodiertes `https://www.qrmaster.net/dashboard` im Mail-Footer
+- `src/app/(main)/api/auth/google/route.ts:40,97` — `redirect_uri` (deckt A4 ab)
+
+### B3. Post-Auth-Sprung auf app.*
+Die einzige Cross-Host-Stelle. `sanitizeRedirectPath` (`src/lib/auth-flow.ts:4`) erlaubt bewusst
+nur relative Pfade — bleibt so, ich baue den Host separat davor:
+
+- `src/app/(main)/(auth)/login/ClientPage.tsx:56` und `login/LoginClient.tsx:65`
+- `src/app/(main)/(auth)/signup/ClientPage.tsx:70`
+- `src/app/(main)/api/auth/google/route.ts:224,228` — Server-Redirect
+- `src/app/(main)/api/auth/verify-email/route.ts:38` — setzt Cookie und redirected
+- `src/lib/auth-flow.ts:46` — `getPostOnboardingDestination`
+
+Muster: relativen Zielpfad wie heute bestimmen, dann `new URL(path, APP_URL)`. Weil das
+Auth-Cookie nach B1 auf `.qrmaster.net` gilt, ist der Nutzer nach dem Sprung sofort eingeloggt —
+kein Token-Handover über die URL nötig.
+
+### B4. Onboarding-Checkliste
+`src/components/dashboard/OnboardingChecklist.tsx:141` verlinkt `/onboarding` mit
+`redirect=/dashboard`. Beide Pfade liegen nach dem Umzug auf app.* → bleibt relativ, keine
+Änderung. Nur verifizieren.
+
+### B5. Middleware: Host-Routing
+`src/middleware.ts` — Kern des Umbaus. Der bestehende Apex-Redirect (Zeile 49) bleibt unberührt.
+Neu, direkt danach:
+
+- Host `app.qrmaster.net`:
+  - `/api/*`, `/_next/*`, statische Dateien: durchlassen (Stripe-Webhook, CSRF, alles)
+  - `protectedPaths` (Zeile 145) + `/upgrade` + `/onboarding`: bedienen wie heute
+  - alles andere: 301 auf `WWW_URL` + gleicher Pfad
+  - `/r/*`: 301 auf www — QR-Redirects gehören nicht auf die App-Subdomain
+- Host `www.qrmaster.net`:
+  - `protectedPaths` + `/upgrade` + `/onboarding`: 301 auf `APP_URL` + Pfad + Query
+    (damit alte Bookmarks und der Mail-Footer-Link weiter funktionieren)
+- Auth-Fail-Redirect (Zeile 166): zeigt auf `/signup` — das liegt auf www, also absolut
+  auf `WWW_URL` umstellen, `redirect`-Param bleibt relativ
+
+`/login` und `/signup` bleiben in `publicPaths` und werden nur auf www bedient.
+
+### B6. Indexierung der Subdomain dichtmachen
+`app.*` darf nicht in den Index, sonst Duplicate Content.
+
+- `src/middleware.ts`: auf Host `app.*` `X-Robots-Tag: noindex, nofollow` auf alle Responses
+- `public/robots-app.txt` neu anlegen (`User-agent: * / Disallow: /`), Middleware rewritet
+  `/robots.txt` auf app.* dorthin. `src/app/robots.ts` bleibt für www unverändert.
+- `/sitemap.xml` auf app.* → 301 auf www
+
+Gute Nachricht: `/dashboard`, `/create`, `/settings` sind in `src/app/robots.ts:7` bereits
+disallowed und nicht in der Sitemap → **kein Ranking-Verlust durch den Umzug.** Die Canonicals
+sind ohnehin hart auf www verdrahtet (`src/app/(main)/layout.tsx:13`).
+
+### B7. Docker-Env-Kette
+`NEXT_PUBLIC_*` wird zur Build-Zeit inlined **und** zur Laufzeit serverseitig gelesen. Beide
+Stellen müssen übereinstimmen, sonst gibt es Bugs, die nur im Client oder nur im Server auftreten:
+
+- `Dockerfile:34` — `NEXT_PUBLIC_APP_URL` auf `https://app.qrmaster.net`, neu
+  `ENV NEXT_PUBLIC_WWW_URL="https://www.qrmaster.net"`
+- `docker-compose.yml:58` — `NEXT_PUBLIC_WWW_URL` und `COOKIE_DOMAIN` ins `environment` des
+  `web`-Service durchreichen
+- `env.example` + `.env.example` — neue Variablen dokumentieren
+- `src/lib/env.ts` — optional, das Schema kennt `NEXT_PUBLIC_*` bisher gar nicht
+
+## Deploy-Choreografie
+
+Zwei Deploys, nicht einer. Das entkoppelt das Cookie-Risiko vom Routing-Risiko:
+
+1. **Deploy 1 (nur B1):** Cookie-Domain auf `.qrmaster.net`. Nur www ist live, nach außen
+   unsichtbar. 24 h beobachten: Login, Logout, Checkout müssen normal laufen.
+2. **A1 + A2 + A4:** DNS, Caddy, Google Console. `app.qrmaster.net` antwortet, serviert aber
+   noch dieselbe App wie www — unkritisch, weil noch nicht verlinkt und dank B6 noch nicht
+   indexierbar.
+3. **Deploy 2 (B2–B7):** Host-Routing scharf. Ab hier springt Login auf app.*.
+
+Rollback: Deploy 2 zurücknehmen. Weil das Cookie auf `.qrmaster.net` gilt, bleiben Sessions
+auch nach dem Rollback auf www gültig — niemand wird ausgeloggt. DNS/Caddy können stehen bleiben.
+
+## Testcheckliste (nach Deploy 2)
+
+Jeweils über beide Hosts:
+
+- [ ] `www.qrmaster.net/dashboard` → 301 auf `app.qrmaster.net/dashboard`, eingeloggt
+- [ ] `app.qrmaster.net/pricing` → 301 auf www
+- [ ] Signup auf www → Verify-Mail → Link führt eingeloggt auf app.*
+- [ ] Google-Login von www aus → landet eingeloggt auf app.*/dashboard bzw. /onboarding
+- [ ] Logout auf app.* → auf www **auch** ausgeloggt (prüft B1, häufigster Fehler)
+- [ ] Checkout: Upgrade auf app.* → Stripe → `success_url` app.*/dashboard, Abbruch → www/pricing
+- [ ] Stripe-Portal → zurück auf app.*/settings
+- [ ] Stripe-Webhook feuert weiter (Dashboard → Events, keine 4xx)
+- [ ] **QR-Code neu anlegen + herunterladen → kodierte URL ist `www.qrmaster.net/r/<slug>`**,
+      nicht app.* (prüft B2, das teuerste Fehlerbild)
+- [ ] Bestehender `/r/<slug>` redirected + trackt weiter, vcard/coupon/feedback-Landings laden
+- [ ] Mutation auf app.* (QR umbenennen) → CSRF greift, kein 403
+- [ ] `curl -sI https://app.qrmaster.net/dashboard | grep -i x-robots-tag` → noindex
+- [ ] `https://app.qrmaster.net/robots.txt` → `Disallow: /`
+- [ ] Search Console: `app.qrmaster.net` **nicht** als Property anlegen, keine Sitemap einreichen
+
+## Risiken
+
+| Risiko | Wo | Absicherung |
+|---|---|---|
+| Gedruckte QR-Codes zeigen auf app.* | `QRCodeCard.tsx:82` | B2, explizit im Test |
+| Logout wirkt nicht (Zombie-Cookie) | `logout/route.ts` | B1 löscht beide Varianten |
+| Client/Server-Env divergieren | `Dockerfile` vs. `docker-compose.yml` | B7, beide Stellen setzen |
+| Google-OAuth bricht | Cloud Console | A4, alte URI stehen lassen |
+| Duplicate Content auf app.* | — | B6 vor Deploy 2 |
+
+## Aufwand
+
+- Deine Seite: ~45 min (DNS, Caddy, .env, Google Console, Deploy)
+- Meine Seite: ~4–6 h Code über zwei Deploys
+- Keine DB-Änderung, kein Forced-Logout, kein SEO-Verlust

+# Umsetzungsplan - CRO-Momente, Upgrade-Wege und Retention-Mails
+
+Stand 27. Juli 2026. Alle Datei- und Zeilenangaben gegen den aktuellen Stand verifiziert.
+
+**Getroffene Entscheidungen:**
+- Das Dynamic-Limit zählt künftig nur noch Codes mit `status = ACTIVE`. Pausieren gibt einen Slot frei.
+- Der Upgrade-Weg im Limit-Moment läuft per Direkt-Checkout aus dem Modal. Kein Redirect auf `/pricing`.
+
+---
+
+## Phase 1 - Der Limit-Moment in `/create`
+
+### 1.1 Limit-Query auf ACTIVE umstellen
+
+**Datei:** `src/app/(main)/api/qrs/route.ts`, Zeile 117-121
+
+```ts
+const dynamicQRCount = await db.qRCode.count({
+  where: { userId, type: 'DYNAMIC', status: 'ACTIVE' },
+});
+```
+
+Dieselbe Änderung in `src/app/(main)/api/user/stats/route.ts`, sonst zeigt das Dashboard eine andere Zahl als die API durchlässt.
+
+**Nebenwirkung, die vorher klar sein muss:** Free-Nutzer, die heute pausierte Codes haben, bekommen dadurch rückwirkend Slots frei. Das ist eine Lockerung, keine Verschärfung - es nimmt niemandem etwas weg. Vor dem Deploy einmal zählen, wie viele Nutzer betroffen sind (SQL unten in Abschnitt „Prüf-Queries").
+
+### 1.2 Das Limit-Modal
+
+**Neue Datei:** `src/components/app/DynamicLimitModal.tsx`
+
+Der 403 aus `/api/qrs` liefert bereits `currentCount`, `limit` und `plan` mit. Es braucht keinen zusätzlichen Request.
+
+**Datei:** `src/app/(main)/(app)/create/page.tsx`, Zeile 456-459 - der Redirect entfällt ersatzlos:
+
+```ts
+if (response.status === 403 && responseData.error === 'Limit reached') {
+  setLimitInfo({ current: responseData.currentCount, limit: responseData.limit, plan: responseData.plan });
+  setLimitModalOpen(true);
+  return;
+}
+```
+
+Der Formular-State bleibt dadurch erhalten. Das ist der eigentliche Fix - alles andere ist Ausgestaltung.
+
+**Copy des Modals:**
+
+> ### Dein vierter Code ist fertig. Er braucht nur noch einen Platz.
+>
+> Du nutzt alle 3 dynamischen Codes deines kostenlosen Plans. Dieser hier ist gebaut und wartet - du kannst ihn behalten oder einen bestehenden freigeben.
+>
+> **[ Diesen Code mit Pro speichern - 9 € / Monat ]**
+> [ Einen bestehenden Code pausieren ]
+> [ Stattdessen als statischen Code herunterladen ]
+>
+> *Deine 3 aktiven Codes laufen weiter, egal wie du dich entscheidest.*
+
+Die Zahlen (`vierter`, `3`) kommen aus `limitInfo`, damit das Modal auch für Pro bei 51 stimmt.
+
+**Warum diese drei Optionen:**
+
+Der Hauptbutton verkauft keinen Plan, sondern rettet einen konkreten Code, den der Nutzer gerade in der Hand hat. Option 2 ist die ehrliche Alternative innerhalb des Free-Plans - sie kostet ein paar Conversions und kauft dafür Belief 5 aus dem Necessary-Beliefs-Doc. Option 3 ist der Ausweg ohne Verlust: ein statischer Code löst das Problem zu einem guten Teil, kostet nichts, und die Zusage „läuft nie ab" ist verifiziert. Der Schlusssatz ist Risk Reversal genau an der Stelle, an der die Kategorie ihren schlechtesten Ruf hat.
+
+### 1.3 Direkt-Checkout aus dem Modal
+
+Der Pro-Button ruft `/api/stripe/checkout` direkt auf, mit `priceId`, `plan: 'PRO'` und `userEmail`.
+
+**Datei:** `src/app/(main)/api/stripe/checkout/route.ts`, Zeile 63. Die `success_url` ist aktuell fest auf `/dashboard?success=true`. Sie muss eine optionale `returnPath` aus dem Request-Body akzeptieren, damit der Nutzer nach dem Kauf dorthin zurückkommt, wo er war.
+
+Vor dem Öffnen von Stripe wird der Formularzustand nach `localStorage` geschrieben (`qrm_pending_qr`, mit Zeitstempel). Beim Zurückkommen auf `/create?restored=1` liest die Seite ihn aus, füllt das Formular und zeigt: *„Willkommen zurück. Dein Code steht noch genau so da - jetzt mit Platz."* Danach den Key löschen. Einträge älter als 24 Stunden werden verworfen.
+
+Kein Draft in der Datenbank. Der Zustand ist ohnehin nur im Browser relevant, und eine Draft-Tabelle wäre Infrastruktur für ein Problem, das `localStorage` löst.
+
+### 1.4 Option „Code pausieren" im Modal
+
+Zeigt die aktiven dynamischen Codes des Nutzers mit Titel und Scan-Zahl der letzten 30 Tage. Ein Klick setzt `status = PAUSED` über das bestehende `PATCH /api/qrs/[id]`, danach wird der ursprüngliche POST automatisch wiederholt.
+
+Die Scan-Zahl daneben ist wichtig: sie macht die Entscheidung informiert statt willkürlich. Wer sieht, dass ein Code seit vier Wochen null Scans hat, pausiert ihn ohne schlechtes Gefühl - und wer sieht, dass alle drei laufen, versteht ohne Verkaufstext, warum Pro sinnvoll ist. Das ist Pointing statt Talking.
+
+---
+
+## Phase 2 - `/bulk-creation`
+
+**Datei:** `src/app/(main)/(app)/bulk-creation/page.tsx`, Zeile 232-247
+
+Die Schleife hat kein `else` zu `if (res.ok)`. Fehlgeschlagene Zeilen verschwinden still, und danach meldet ein grüner Toast `${results.length} dynamische QR-Codes erstellt!` - eine Zahl, die kleiner sein kann als das Hochgeladene, ohne jeden Hinweis.
+
+**Fix:**
+
+```ts
+const failed: { row: number; title: string; reason: string }[] = [];
+// im else-Zweig: failed.push({ row: i + 1, title, reason: (await res.json()).error })
+```
+
+Danach, wenn `failed.length > 0`, statt des Erfolgs-Toasts ein Ergebnis-Panel:
+
+> **180 von 200 Codes erstellt.**
+> 20 Zeilen konnten nicht angelegt werden, weil dein Kontingent an dynamischen Codes erschöpft ist. Hier sind sie - du kannst sie als statische Codes erzeugen oder dein Kontingent erhöhen.
+>
+> [ Fehlende Zeilen als CSV ] [ Kontingent erhöhen ]
+
+Zusätzlich in derselben Datei:
+
+- `remainingDynamic` nach dem Lauf vom Server neu laden statt nur lokal herunterzuzählen (Zeile 251). Das ist die Ursache der Race Condition.
+- Die Toasts sind auf Deutsch (`'Du hast keine dynamischen QR-Codes mehr übrig...'`, Zeile 215 und 221), während die restliche App-Oberfläche Englisch ist. Auf Englisch umstellen.
+
+---
+
+## Phase 3 - Upgrade-Wege aus der App
+
+`/pricing` liegt in der `(marketing)`-Route-Group. Wer im Dashboard auf Upgrade klickt, verliert die Sidebar und landet in der Marketing-Site. Zusätzlich liest `PricingClient.tsx` `searchParams` überhaupt nicht - das `?reason=limit_reached`, das `/create` heute anhängt, wird vollständig ignoriert.
+
+Nach der getroffenen Entscheidung läuft der Limit-Fall künftig über das Modal, damit ist der wichtigste Fall gelöst. Es bleiben drei In-App-Links auf `/pricing`:
+
+| Datei | Zeile | Kontext |
+|---|---|---|
+| `dashboard/page.tsx` | 340 | Upgrade-Badge im Header |
+| `create/page.tsx` | 977 | Hinweis „Upgrade to PRO to customize colors" |
+| `create/page.tsx` | 1106 | Hinweis „Upgrade to PRO to add logos" |
+
+Die beiden Hinweise in `/create` sollten dasselbe Modal öffnen wie der Limit-Fall, nur mit anderem Aufhänger („Dein Logo gehört in diesen Code"). Der Nutzer ist mitten im Gestalten - ihn dafür aus der Seite zu werfen ist derselbe Fehler wie beim Limit, nur weniger sichtbar.
+
+Der Dashboard-Badge kann auf `/pricing` zeigen bleiben. Dort ist der Nutzer nicht mitten in einer Aufgabe, es gibt nichts zu verlieren. Nur ein `?from=dashboard` anhängen und in `PricingClient` einen Zurück-Link rendern, damit der Weg zurück nicht über den Browser-Button läuft.
+
+---
+
+## Phase 4 - Post-Download-Popup auf den Tool-Seiten
+
+**Datei:** `src/components/marketing/PostDownloadPopup.tsx`
+
+Timing und die Ablehn-Option `No thanks, keep it static` bleiben unverändert - beides ist richtig gebaut.
+
+Ersetzt werden Headline und Bullet-Liste:
+
+> ### Dieser Code zeigt jetzt für immer auf diese URL.
+>
+> Bei einem dauerhaften Link ist das genau richtig. Falls sich das Ziel je ändert, brauchst du einen neuen Code und neues Druckmaterial.
+>
+> Ein kostenloses Konto gibt dir 3 dynamische Codes: gleiches Bild, Ziel jederzeit änderbar, jeder Scan gezählt.
+>
+> **[ Kostenloses Konto anlegen - keine Karte ]**
+> *Nein danke, statisch reicht*
+
+Die vier Bullets entfallen. Drei gleichrangige Vorteile sind schwächer als ein Satz, der den einen benennt - in einer Liste aus vier gleich formatierten Punkten ist keiner davon wichtig.
+
+Neues Prop `variant`, das nur die erste Zeile austauscht:
+
+| Tool | Erste Zeile |
+|---|---|
+| Google Review | Dieser Code zeigt jetzt für immer auf dieses Google-Profil. |
+| WiFi | Dieser Code enthält jetzt dauerhaft dieses WLAN-Passwort. |
+| vCard | Dieser Code enthält jetzt dauerhaft diese Kontaktdaten. |
+| Crypto | Dieser Code enthält jetzt dauerhaft diese Wallet-Adresse. |
+| Standard | Dieser Code zeigt jetzt für immer auf diese URL. |
+
+Die WiFi-Variante ist die stärkste, weil sie einen Umstand benennt, den fast niemand vorher bedenkt: Wer das Passwort ändert, hat wertloses Druckmaterial.
+
+Betroffen sind die 10+ Generator-Komponenten, die `PostDownloadPopup` einbinden - dort jeweils nur das `variant`-Prop ergänzen.
+
+**Zusätzlich:** `shouldShowDownloadPopup()` prüft einen einzigen `localStorage`-Key. Wer das Popup einmal gesehen hat, sieht es auf keiner anderen Tool-Seite je wieder - auch nicht Monate später in einem anderen Kontext. Vorschlag: Key mit Zeitstempel, Wiedervorlage nach 30 Tagen.
+
+---
+
+## Phase 5 - Retention-Mails
+
+**Datei:** `src/lib/email.ts` und `src/app/(main)/api/cron/retention-emails/route.ts`
+
+### 5.1 Tag-7-Mail: Trigger vom Kalender aufs Verhalten
+
+Aktuell feuert sie bei `createdAt < 7 Tage` und `qrCount > 0`. Ein Nutzer mit einem einzigen Code bekommt „You're 2 away from the free limit" - eine Verkaufsmail über ein Limit, das ihn nicht drückt, abgeschickt unter deinem Namen.
+
+Neue Logik:
+
+| Zustand | Auslöser | Mail |
+|---|---|---|
+| aktive dynamische Codes = Limit | sobald erreicht | Limit-Mail, Marker `limitReachedNudgeSentAt` |
+| 1-2 von 3 belegt, Tag 7 | Tag 7 | keine Upgrade-Mail |
+| erster Scan liegt vor | 1 Tag danach | Erster-Scan-Mail, Marker `firstScanNudgeSentAt` |
+
+In der Vergleichstabelle der Limit-Mail entfällt die Zeile `CSV export: Free ✓ / Pro ✓`. Eine Zeile, in der beide Spalten identisch sind, gehört nicht in eine Upgrade-Tabelle - sie verwässert die drei, die einen Unterschied zeigen.
+
+### 5.2 Neue Mail: erster Scan
+
+`User.firstScanAt` existiert bereits und wird in `src/app/(main)/r/[slug]/route.ts` (Zeile 150-153 und 263-266) gesetzt. Es fehlt nur ein Versand-Marker.
+
+Betreff: **Dein Code wurde gerade zum ersten Mal gescannt**
+
+> Um {Uhrzeit}, auf einem {Gerät}, aus {Land}. Dein Code „{Titel}" ist im Einsatz.
+>
+> Ab jetzt zählt jeder weitere Scan mit. In ein paar Tagen siehst du, wann die meisten kommen - und ob sich der Ort lohnt, an dem du den Code platziert hast.
+>
+> [ Scans ansehen ]
+
+Kein Verkaufsargument. Diese Mail hat einen Anlass, der nicht konstruiert ist, und ist der Moment, in dem die Positionierung zum ersten Mal einlöst. Sie ist die einzige in der Sequenz, deren Anlass nicht vom Kalender kommt.
+
+### 5.3 Tag-30-Mail auf Scan-Daten umbauen
+
+Zwei Probleme mit der jetzigen Fassung:
+
+Der Satz *„The one thing I hear most from Pro users who switched after a few weeks: they wish they'd added their brand sooner"* behauptet ein Muster aus Kundengesprächen. Wenn es die gab: echtes Zitat rein. Wenn nicht: **streichen** - das ist ein erfundenes Testimonial in indirekter Rede und verstößt gegen die Beweisregel im Product Context. Bei einer Zielgruppe, die Bewertungsportale liest, ist das die teuerste Art von Satz.
+
+Und Branding ist der schwächere von zwei verfügbaren Aufhängern. Nach 30 Tagen hat der Nutzer Scan-Daten. Neuer Aufbau:
+
+> Deine Codes wurden diesen Monat {n}-mal gescannt, {Vorname}.
+>
+> Die meisten davon {Wochentag}s. Was du noch nicht sehen kannst: von welchen Geräten sie kamen und aus welchen Orten - und damit, welche deiner Platzierungen die Scans wirklich gebracht hat.
+>

+
+Damit ist der Kaufgrund aus dem hergeleitet, was der Nutzer selbst erlebt hat. Deckt sich mit Offer Brief §10, Option 1 - auf Analytics-Tiefe metern statt auf Code-Anzahl -, und ist die erste Stelle, an der man das testen kann, ohne das Pricing anzufassen.
+
+### 5.4 Tag-3-Mail: kleine Korrektur
+
+Betreff `You haven't made one yet` kann als Vorwurf gelesen werden - im Body löst die Headline es auf, im Posteingang steht der Betreff allein. Alternative gleicher Länge: **`Your 3 free codes are still sitting there`**.
+
+---
+
+## Phase 6 - QR-Design nach Plan gestaffelt
+
+Neue Staffelung: Farben ab Free, Formen ab Pro, alles ab Business.
+
+### 6.0 Der technische Blocker, der vorher geklärt sein muss
+
+`/create` rendert über `QRCodeSVG` aus `qrcode.react` (Zeile 6 und 1233). **Diese Bibliothek kann ausschließlich quadratische Module.** Es gibt heute überhaupt keine Formauswahl im Produkt - nicht weil sie gesperrt wäre, sondern weil der Renderer sie nicht kann.
+
+Für Formen muss der Renderer also getauscht werden. Es gibt zwei Kandidaten, und sie decken unterschiedlich viel ab:
+
+| Renderer | Kann | Kann nicht |
+|---|---|---|
+| `qr-code-styling` (liegt bereits als Dependency in `package.json`, Zeile 64, ungenutzt) | square, dots, rounded, extra-rounded, classy, classy-rounded, Eye-Styles getrennt, Verläufe, Logo | star, plus, hexagon, diamond, mosaic, liquid |
+| Canvas-Renderer aus `qr-design-showcase.html` | alle 11 Formen inklusive star, plus, hexagon, diamond, mosaic, liquid, Rahmen mit Label, Logo-Formen | ist eigener Code, muss portiert und gepflegt werden |
+
+Das trifft sich gut mit der gewünschten Staffelung: **Pro läuft komplett über `qr-code-styling`** - vier Formen, geringer Aufwand, Bibliothek ist schon da. **Business braucht den portierten Showcase-Renderer** für die exotischen Formen. Damit ist der Mehraufwand genau dort, wo auch der höhere Preis ist.
+
+### 6.1 Free - Farben
+
+**Datei:** `src/app/(main)/(app)/create/page.tsx`, Zeile 167
+
+```ts
+const canCustomizeColors = true;              // war: PRO || BUSINESS
+const canUseShapes       = userPlan === 'PRO' || userPlan === 'BUSINESS';
+const canUseFullDesign   = userPlan === 'BUSINESS';
+const canUseLogo         = userPlan === 'PRO' || userPlan === 'BUSINESS';
+```
+
+Damit fallen die beiden Zwangsüberschreibungen in Zeile 408-409 weg, die heute für Free-Nutzer stumpf `#000000` und `#FFFFFF` einsetzen. Der Upgrade-Hinweis-Block ab Zeile 972 („Upgrade to PRO to customize colors, add logos, and brand your QR codes") entfällt komplett - er stimmt danach nicht mehr.
+
+Der Logo-Block ab Zeile 1104 bleibt, wird aber auf `canUseLogo` umgestellt statt auf `canCustomizeColors`, und öffnet künftig das Modal aus Phase 3 statt auf `/pricing` zu verlinken.
+
+**Der Kontrast-Check bleibt aktiv.** `calculateContrast` gibt es bereits (Zeile 221). Sobald Farben für alle offen sind, wird er wichtiger, nicht unwichtiger - Free-Nutzer sind die Gruppe mit der geringsten Erfahrung darin, was noch scannbar ist. Bei zu geringem Kontrast eine Warnung, kein Verbot: *„Dieser Kontrast ist grenzwertig. Auf gedrucktem Material scannen helle Codes auf hellem Grund oft nicht."*
+
+### 6.2 Pro - vier Modulformen
+
+Umsetzung über `qr-code-styling`. Bewusst nur vier, nicht sechs:
+
+| Auswahl | `dotsOptions.type` | Wofür |
+|---|---|---|
+| Eckig (klassisch) | `square` | Standard, höchste Scan-Sicherheit |
+| Abgerundet | `rounded` | weicher, ohne Lesbarkeit zu kosten |
+| Punkte | `dots` | modern, deutlich sichtbarer Unterschied |
+| Fließend | `classy-rounded` | markantester der vier |
+
+Dazu die Eye-Styles (`cornersSquareOptions`, `cornersDotOptions`) - eckig, abgerundet, Kreis. Die Augen machen optisch mehr aus als die Module selbst und kosten nichts extra, weil dieselbe Bibliothek sie mitbringt.
+
+Vier Optionen statt aller sechs, weil die Auswahl selbst ein Verkaufsargument ist: Pro fühlt sich vollständig an, Business hat sichtbar mehr. Sechs fast identische Varianten wirken dagegen wie eine lange Liste ohne Unterschied.
+
+### 6.3 Business - vollständiger Designer
+
+Portierung des Renderers aus `qr-design-showcase.html` in eine Komponente `src/components/generator/AdvancedQRRenderer.tsx`. Was damit dazukommt:
+
+- **Modulformen:** diamond, star, hexagon, plus, mosaic, liquid zusätzlich zu den vier aus Pro
+- **Eye-Frames getrennt:** eckig, abgerundet, Kreis, Blatt, Flower/Squircle, Hexagon
+- **Eye-Balls getrennt:** eckig, abgerundet, Kreis, Diamant, Stern, Hexagon
+- **Farbverläufe:** linear und radial statt einfarbig
+- **Rahmen mit Label:** weiße Karte mit Schatten, Label oben oder unten (z. B. „Speisekarte", „Jetzt bewerten")
+- **Logo-Formen:** Punkt, Quadrat, Herz, Blitz, WLAN-Symbol
+- **Fehlerkorrektur-Stufe** frei wählbar (L/M/Q/H)
+
+**Erweiterungsvorschläge über die Showcase hinaus**, weil beim Business-Kunden die Wiederholbarkeit zählt und nicht die einzelne Spielerei:
+
+1. **Design-Vorlagen speichern.** Ein einmal gebautes Design als benanntes Preset sichern und auf neue Codes anwenden. Das ist für eine Agentur mit mehreren Kunden der eigentliche Wert - nicht die Sternform, sondern dass Kunde A immer gleich aussieht.
+2. **Preset auf den Bulk-Flow anwenden.** Ein Preset auswählen und alle 500 Codes eines Uploads tragen es. Das verbindet Phase 2 mit diesem Feature und ist das erste Argument für Business, das nicht nur eine Zahl ist.
+3. **Print-Vorschau in Originalgröße.** Der Code in 2×2 cm, 4×4 cm und 10×10 cm dargestellt, mit Hinweis ab wann es kritisch wird. Passt zu den Druckangaben, die im Offer Brief bereits als verifizierter Fakt geführt werden.
+
+### 6.4 Scanbarkeit - der Teil, der nicht optional ist
+
+Exotische Formen füllen weniger Fläche pro Modul. Star, plus und mosaic reduzieren die Kontrastfläche spürbar, und in Kombination mit einem Logo in der Mitte und einer kleinen Druckgröße kippt die Lesbarkeit. Die Showcase weist bei „H (30%)" schon auf „empfohlen bei Logo" hin - das gehört ins Produkt übernommen, und zwar strenger:
+
+- Bei star, plus, mosaic oder liquid automatisch auf Fehlerkorrektur **H** hochsetzen und das sichtbar begründen
+- Bei Logo plus exotischer Form eine Warnung mit Mindestdruckgröße
+- Ein **Test-Scan-Hinweis** vor dem Download: *„Scanne den Code einmal mit deinem eigenen Handy, bevor du ihn in Druck gibst."*
+
+Das ist kein Beiwerk, sondern der Proof-Layer aus der Positionierung an einer Stelle, an der es konkret wird. Ein Anbieter, der vor seinem eigenen Feature warnt, wenn es kritisch wird, belegt Belief 5 besser als jede Aussage über Transparenz.
+
+### 6.5 Was die Umstellung beim Pricing kostet
+
+Ehrlich gesagt: Farben waren laut Offer Brief §10 einer von genau **drei** Gründen, heute auf Pro zu wechseln (die anderen zwei: mehr als 3 aktive Codes, Device- und Location-Breakdown). Diesen Grund gibt man mit dieser Änderung auf.
+
+Das ist meiner Einschätzung nach trotzdem richtig, aber aus einem anderen Grund als „großzügiger sein":
+
+Farben sind kein guter Upgrade-Anlass, weil man sie schon im kostenlosen Zustand *sehen* will, um zu verstehen, ob das Produkt etwas taugt. Ein Free-Nutzer, der nur schwarze Codes bauen kann, hält das Produkt für ein Basiswerkzeug - und bewertet es entsprechend, auch in Vergleichen. Formen sind der bessere Verkäufer, weil der Unterschied größer aussieht und man ihn in der Vorschau zeigen kann, bevor man ihn freischaltet: der Nutzer wählt „Punkte", sieht das Ergebnis live, und erst der Download fragt nach Pro.
+
+**Folgeänderungen an der Preis-Copy** in `src/i18n/en.json` und `src/app/(main)/(marketing)/pricing/PricingClient.tsx`:
+
+| Plan | vorher | nachher |
+|---|---|---|
+| Free | „Standard QR design templates" | „Deine Farben - Vorder- und Hintergrund frei wählbar" |
+| Pro | „Custom branding (colors & logos)" | „4 Modulformen, eigene Eye-Styles und dein Logo im Code" |
+| Business | (kein Design-Punkt) | „Voller Designer: 10 Formen, Verläufe, Rahmen mit Label, speicherbare Design-Vorlagen" |
+
+Dieselbe Anpassung auf `/custom-qr-code-generator`, dessen Meta-Description aktuell „Put your logo and brand colors into the code itself" sagt - das bleibt korrekt, weil Logo weiterhin Pro ist, aber die Seite sollte künftig zeigen, was auf welcher Stufe geht.
+
+### 6.6 Keine Datenbankänderung nötig
+
+`QRCode.style` ist bereits `Json` (siehe `prisma/schema.prisma`). Alle neuen Felder - `dotType`, `eyeFrameType`, `eyeBallType`, `gradient`, `frameLabel`, `logoShape`, `ecLevel` - passen ohne Schemaänderung hinein. Bestehende Codes haben die Felder schlicht nicht und fallen auf die Defaults zurück.
+
+**Ausnahme:** Wenn die speicherbaren Design-Vorlagen aus 6.3 kommen sollen, braucht es eine eigene Tabelle. SQL dafür steht unten, ist aber optional und kann später nachgezogen werden.
+
+---
+
+## SQL - alle nötigen Datenbankänderungen
+
+Nach der Policy in `CLAUDE.md`: keine Prisma-Migrationen, nur direkte Statements.
+
+```sql
+-- Marker für die neuen verhaltensbasierten Retention-Mails
+ALTER TABLE "User" ADD COLUMN IF NOT EXISTS "limitReachedNudgeSentAt" TIMESTAMP(3);
+ALTER TABLE "User" ADD COLUMN IF NOT EXISTS "firstScanNudgeSentAt"    TIMESTAMP(3);
+
+-- Index für den Cron: sucht Nutzer mit erstem Scan, die die Mail noch nicht haben
+CREATE INDEX IF NOT EXISTS "User_firstScanAt_firstScanNudgeSentAt_idx"
+  ON "User" ("firstScanAt", "firstScanNudgeSentAt");
+
+-- Index für die neue Limit-Query (zählt nur noch ACTIVE)
+CREATE INDEX IF NOT EXISTS "QRCode_userId_type_status_idx"
+  ON "QRCode" ("userId", "type", "status");
+```
+
+Für Phase 6 ist **nichts** davon nötig - `QRCode.style` ist bereits `Json`. Optional, nur falls die speicherbaren Design-Vorlagen aus 6.3 gebaut werden:
+
+```sql
+CREATE TABLE IF NOT EXISTS "QRDesignPreset" (
+  "id"        TEXT PRIMARY KEY,
+  "userId"    TEXT NOT NULL REFERENCES "User"("id") ON DELETE CASCADE,
+  "name"      TEXT NOT NULL,
+  "style"     JSONB NOT NULL,
+  "createdAt" TIMESTAMP(3) NOT NULL DEFAULT now(),
+  "updatedAt" TIMESTAMP(3) NOT NULL DEFAULT now()
+);
+
+CREATE INDEX IF NOT EXISTS "QRDesignPreset_userId_idx" ON "QRDesignPreset" ("userId");
+CREATE UNIQUE INDEX IF NOT EXISTS "QRDesignPreset_userId_name_key" ON "QRDesignPreset" ("userId", "name");
+```
+
+Ausführen über `npm run docker:db` oder:
+
+```bash
+docker-compose exec db psql -U postgres -d qrmaster -c 'ALTER TABLE "User" ADD COLUMN IF NOT EXISTS "limitReachedNudgeSentAt" TIMESTAMP(3);'
+```
+
+Danach `prisma/schema.prisma` im Block `// Retention email tracking` ergänzen:
+
+```prisma
+  limitReachedNudgeSentAt DateTime?
+  firstScanNudgeSentAt    DateTime?
+```
+
+und beim Model `QRCode` den Index:
+
+```prisma
+  @@index([userId, type, status])
+```
+
+Abschließend `npx prisma generate` - kein `migrate`.
+
+### Prüf-Queries vor dem Deploy
+
+```sql
+-- Wie viele Free-Nutzer bekommen durch die ACTIVE-Umstellung Slots frei?
+SELECT COUNT(DISTINCT u.id)
+FROM "User" u
+JOIN "QRCode" q ON q."userId" = u.id
+WHERE u.plan = 'FREE' AND q.type = 'DYNAMIC' AND q.status = 'PAUSED';
+
+-- Wie viele Nutzer bekämen die Erster-Scan-Mail beim ersten Cron-Lauf?
+SELECT COUNT(*) FROM "User"
+WHERE "firstScanAt" IS NOT NULL AND "firstScanNudgeSentAt" IS NULL;
+```
+
+Die zweite Zahl ist wichtig: Beim ersten Lauf würde die neue Mail an **alle** Bestandsnutzer mit Scan-Historie gehen - auch an solche, deren erster Scan Monate zurückliegt. Das wäre kein Anlass mehr, sondern Spam. Der Cron braucht deshalb ein Zeitfenster, etwa `firstScanAt > now() - interval '7 days'`, oder man setzt die Spalte bei Bestandsnutzern einmalig vor:
+
+```sql
+UPDATE "User" SET "firstScanNudgeSentAt" = now()
+WHERE "firstScanAt" IS NOT NULL AND "firstScanAt" < now() - interval '7 days';
+```
+
+---
+
+## Reihenfolge
+
+| # | Was | Aufwand | DB |
+|---|---|---|---|
+| 1 | Limit-Query auf ACTIVE, beide Endpoints | klein | Index |
+| 2 | Limit-Modal ohne Redirect | mittel | nein |
+| 3 | Direkt-Checkout plus `returnPath` und localStorage-Wiederherstellung | mittel | nein |
+| 4 | `bulk-creation`: Fehlerbehandlung und Ergebnis-Panel | klein | nein |
+| 5 | Popup-Copy plus `variant` pro Tool-Seite | klein | nein |
+| 6 | Retention: Trigger umstellen, Tabellen-Zeile raus, Betreff Tag 3 | klein | 1 Spalte |
+| 7 | Erster-Scan-Mail | mittel | 1 Spalte |
+| 8 | Tag-30 auf Scan-Daten, unbelegten Satz klären | klein | nein |
+| 9 | Farben ab Free freischalten, Pricing-Copy nachziehen | klein | nein |
+| 10 | Pro-Formen über `qr-code-styling`, Renderer-Tausch in `/create` | mittel | nein |
+| 11 | Business-Designer, Showcase-Renderer portieren | groß | nein |
+| 12 | Design-Vorlagen speichern und auf Bulk anwenden | mittel | Tabelle |
+
+1 bis 3 gehören zusammen und sollten gemeinsam live gehen. 4 und 5 sind unabhängig und können jederzeit dazwischen. 6 bis 8 brauchen die SQL-Statements und den einmaligen `UPDATE` für Bestandsnutzer.
+
+**9 ist der schnellste Gewinn im ganzen Dokument** - eine Zeile (`canCustomizeColors = true`) plus Copy-Anpassung, und das Produkt wirkt für jeden neuen Nutzer sofort weniger nach Basiswerkzeug. Sie sollte nicht auf 10 warten.
+
+10 ist der Renderer-Tausch und damit der Punkt, an dem `/create` einmal gründlich getestet werden muss - Vorschau, Download PNG, Download SVG, Logo-Overlay und die Frame-Optionen hängen alle daran.
+
+11 und 12 sind der eigentliche Business-Ausbau. 12 ist dabei wertvoller als 11: eine Agentur kauft nicht die Sternform, sondern dass Kunde A auf 500 Codes gleich aussieht.

+# Plan: Testumgebung auf testmodul.qrmaster.net
+
+Stand: 2026-08-12 · Ziel: eine vollständige zweite Instanz auf `testmodul.qrmaster.net`, die
+einen anderen Branch (`test`) fährt, damit riskante Features - z.B. ein Bot, der bei
+Kundenerfolgen automatisch tweetet - vor dem Merge nach `master` real getestet werden können.
+
+**Status: nur Planung. Es wurde noch kein Code geändert.**
+
+## Architektur
+
+Zweiter, vollständig eigenständiger Compose-Stack aus demselben Repo, anderer Branch,
+eigene Datenbank, eigenes Redis. Caddy routet `testmodul.qrmaster.net` auf den Test-Container.
+
+```
+www.qrmaster.net   ─┐
+app.qrmaster.net   ─┴─> qrmaster-web       (Branch master, Prod-DB)
+testmodul.qrmaster.net ─> qrmaster-test-web (Branch test, eigene DB)
+```
+
+Prod und Test teilen sich **nichts** außer dem Docker-Netzwerk `qrmaster-network` (das ist
+`external: true`, darüber erreicht Caddy beide Container per Namen).
+
+## Ausgangslage im Repo
+
+Im Working Tree liegen uncommittete Änderungen, die nicht aus der Subdomain-Arbeit stammen:
+
+- `src/lib/cookieConfig.ts` - `getAuthCookieName()` ist angelegt (liest `AUTH_COOKIE_NAME`,
+  Default `userId`)
+- `src/lib/session.ts` - importiert `getAuthCookieName`, **benutzt es aber nicht**; Zeile 14
+  hat weiterhin `export const AUTH_COOKIE_NAME = 'userId'`
+
+Damit ist die Funktion aktuell wirkungslos. Die Verkabelung fehlt an 6 Stellen (siehe unten).
+Vor dem Weiterbauen klären, ob diese Änderungen bewusst so stehen oder committed werden sollen.
+
+Ein Branch `test` existiert noch nicht. Vorhanden: `analytics`, `dynamisch`,
+`feature/mockup-landing-page`, `icons`, `master`.
+
+## Falle 1 - Cookie-Kollision (blockierend)
+
+Produktion setzt das Session-Cookie `userId` auf `.qrmaster.net`. Der Browser schickt es damit
+**auch an `testmodul.qrmaster.net`**. Setzt Test sein eigenes `userId` als Host-Cookie, liegen
+zwei gleichnamige Cookies vor, und `req.cookies.get('userId')` in
+[middleware.ts:250](src/middleware.ts:250) liefert undefiniert welches davon. Folge: Login auf
+Test verhält sich sporadisch wie ausgeloggt - ein Fehlerbild, das schwer zu greifen ist, weil es
+vom Cookie-Zustand des jeweiligen Browsers abhängt.
+
+**Lösung:** Cookie-Name pro Umgebung konfigurierbar. `getAuthCookieName()` fertig verkabeln,
+Test setzt `AUTH_COOKIE_NAME=userId_test`.
+
+Zu ändernde Stellen:
+
+| Datei | Was |
+|---|---|
+| `src/lib/session.ts:14` | `AUTH_COOKIE_NAME`-Konstante durch `getAuthCookieName()` ersetzen (Zeilen 71, 78 ziehen nach) |
+| `src/middleware.ts:250` | `req.cookies.get('userId')` → `getAuthCookieName()` |
+| `src/app/(main)/api/auth/google/route.ts:227` | `cookies.set('userId', …)` |
+| `src/app/(main)/api/auth/verify-email/route.ts:40` | `cookies.set('userId', …)` |
+| `src/app/(main)/api/auth/logout/route.ts:12` | Eintrag in `appendExpiredCookies` |
+| `src/app/(main)/api/user/delete/route.ts:77` | `cookies().delete('userId')` |
+
+Wie `COOKIE_DOMAIN` muss `AUTH_COOKIE_NAME` **auch zur Build-Zeit** gesetzt sein - `process.env`
+wird ins Edge-Middleware-Bundle inlined. Also `ARG` + `ENV` im Dockerfile und als Build-Arg im
+Compose-Override, analog zu `COOKIE_DOMAIN`.
+
+Achtung beim Umstellen der Produktion: ändert sich dort der Cookie-Name, werden **alle
+bestehenden Sessions ungültig** (alle Nutzer ausgeloggt). Deshalb Prod beim Default `userId`
+lassen und nur Test abweichen - dann passiert genau nichts.
+
+## Falle 2 - Host-Routing würde nach Prod umleiten
+
+Die Middleware kennt nur zwei Hosts. Auf `testmodul.qrmaster.net` greift der Zweig
+`else if (isAppPath(path))` und schickt `/dashboard` per 301 auf **app.qrmaster.net**, also in
+die Produktion.
+
+**Lösung ohne Codeänderung:** Test zeigt beide Origins auf sich selbst. Dann ist
+`isHostSplitEnabled()` false, `getAppHostname()` liefert null, und das komplette Host-Routing
+schaltet sich ab. Test läuft als Ein-Host-Umgebung mit Marketing *und* App unter einer Domain -
+genau wie die lokale Entwicklung.
+
+Das ist der Grund, warum beide Variablen in `.env.test` identisch sein müssen. Wer dort später
+aus Versehen `NEXT_PUBLIC_APP_URL=https://app.qrmaster.net` einträgt, schickt seine Testklicks
+in die Produktion.
+
+## Falle 3 - ausgehende Nebenwirkungen
+
+Das ist beim Twitter-Bot der eigentliche Punkt. Eine Testumgebung, die auf echte Dienste zeigt,
+ist keine Testumgebung.
+
+| Dienst | Auf Test |
+|---|---|
+| Twitter/X | eigener App-Key auf einen Test-Account, **oder** ein `DRY_RUN`-Flag, das den Tweet nur loggt |
+| Stripe | Test-Keys (`sk_test_…`), eigener Webhook-Endpoint auf testmodul |
+| Resend / SMTP | Test-Key oder komplett deaktivieren - sonst mailt Test an echte Kunden |
+| Meta Conversions / PostHog / Umami | leer lassen, sonst verschmutzt Test die Prod-Analytics |
+| Cron (Retention-Mails) | auf Test abschalten |
+
+Empfehlung für den Bot: das `DRY_RUN`-Flag von Anfang an einbauen, nicht erst wenn es einmal
+schiefging. Ein Bot, der Kundenerfolge tweetet, ist genau die Sorte Feature, die man nicht
+"kurz mal live" testen will.
+
+## .env.test
+
+```dotenv
+NODE_ENV=production
+
+# Ein-Host-Betrieb: schaltet das Host-Routing ab
+NEXT_PUBLIC_WWW_URL=https://testmodul.qrmaster.net
+NEXT_PUBLIC_APP_URL=https://testmodul.qrmaster.net
+NEXTAUTH_URL=https://testmodul.qrmaster.net
+
+# Host-Cookie, nicht .qrmaster.net - sonst leckt die Test-Session nach Prod
+COOKIE_DOMAIN=
+AUTH_COOKIE_NAME=userId_test
+
+# Anderes Secret: ein Leak auf Test kann dann keine Prod-Session fälschen
+NEXTAUTH_SECRET=<eigenes Secret>
+IP_SALT=<eigenes Salt>
+
+# Nicht indexieren
+NEXT_PUBLIC_INDEXABLE=false
+
+# Eigene DB im Test-Stack
+POSTGRES_USER=postgres
+POSTGRES_PASSWORD=<eigenes, hex - ein "/" aus base64 zerlegt die DATABASE_URL>
+POSTGRES_DB=qrmaster_test
+# DATABASE_URL nicht setzen - Compose baut sie aus den drei Werten oben
+
+# Test-Keys / leer, siehe Falle 3
+STRIPE_SECRET_KEY=sk_test_…
+RESEND_API_KEY=
+```
+
+`NEXTAUTH_URL` darf hier auf testmodul zeigen - der einzige echte Leser ist die
+Social-Assets-Route, und die soll auf Test ohnehin nicht gegen die verifizierte TikTok-Domain
+laufen.
+
+## Infra
+
+**`docker-compose.test.yml`** als Override, das nur die Abweichungen setzt:
+
+- `container_name`: `qrmaster-test-db`, `qrmaster-test-redis`, `qrmaster-test-web` - die Namen
+  sind im Basis-File fest vergeben und würden sonst kollidieren
+- Host-Ports entfernen - `5435` (db) und `8080` (adminer) sind schon von Prod belegt
+- `entrypoint: ["node", "server.js"]` für `web`, siehe Migrationen oben
+- Build-Args für `COOKIE_DOMAIN`, `AUTH_COOKIE_NAME`, `NEXT_PUBLIC_*`
+
+### Netzwerk-Isolation (kritisch)
+
+`db` und `redis` hängen im Basis-File am Netzwerk `qrmaster-network`
+([docker-compose.yml:22](docker-compose.yml:22)), und das ist `external: true`, also für beide
+Stacks dasselbe. Compose vergibt jedem Service automatisch einen Netzwerk-Alias mit seinem
+Servicenamen - zwei Stacks mit einem Service `db` am selben Netzwerk heißt: **`db` löst auf
+zwei Container auf und Dockers DNS wählt zufällig.** Der Test-Container könnte damit auf der
+Produktionsdatenbank landen, nicht deterministisch, sondern mal so und mal so.
+
+Deshalb bekommt der Test-Stack ein eigenes internes Netzwerk. Nur `web` hängt zusätzlich am
+geteilten Netz, damit Caddy es erreicht:
+
+```yaml
+services:
+  db:
+    container_name: qrmaster-test-db
+    ports: !reset []
+    networks: [test-internal]
+  redis:
+    container_name: qrmaster-test-redis
+    networks: [test-internal]
+  web:
+    container_name: qrmaster-test-web
+    entrypoint: ["node", "server.js"]
+    networks: [test-internal, qrmaster-network]
+
+networks:
+  test-internal:
+    driver: bridge
+```
+
+`POSTGRES_DB` heißt auf Test `qrmaster_test`. Die Trennung kommt zwar schon vom eigenen
+Container und Volume, aber der abweichende Name macht bei einer von Hand getippten
+`psql`-Sitzung sofort sichtbar, auf welcher Instanz man ist - die billigste Versicherung
+gegen ein `DELETE` in der falschen Datenbank.
+
+Dafür muss der Healthcheck mitgezogen werden: das Basis-File hat `pg_isready -d qrmaster`
+hartkodiert ([Zeile 19](docker-compose.yml:19)). Ohne Override prüft er eine Datenbank, die
+es nicht gibt, der Container bleibt `unhealthy`, und `web` startet wegen
+`depends_on: condition: service_healthy` nie.
+
+Start:
+
+```bash
+docker compose -p qrmaster-test --env-file .env.test \
+  -f docker-compose.yml -f docker-compose.test.yml up -d --build
+```
+
+Der Projektname `-p qrmaster-test` gibt automatisch eigene Volumes - die Test-DB kann die
+Prod-DB also nicht anfassen.
+
+**Caddy:**
+
+```caddyfile
+testmodul.qrmaster.net {
+    reverse_proxy qrmaster-test-web:3000
+}
+```
+
+**`robots.ts`** an `NEXT_PUBLIC_INDEXABLE` koppeln. Aktuell liefert es hart `Allow` plus
+www-Sitemap; auf Test soll `Disallow: /` stehen. `NEXT_PUBLIC_INDEXABLE=false` setzt heute nur
+das Meta-Tag in den beiden Layouts, nicht die robots.txt.
+
+## Branch-Workflow
+
+```bash
+git checkout -b test master
+git push -u origin test
+```
+
+Deploy auf Test: auf dem Server `git checkout test && git pull`, dann der Compose-Befehl oben.
+Rebuild ist immer nötig, weil `NEXT_PUBLIC_*` und `AUTH_COOKIE_NAME` zur Build-Zeit inlined
+werden.
+
+Ablauf für ein Feature: Branch von `test` abzweigen → auf Test deployen und prüfen → nach
+`master` mergen → Prod-Deploy. `test` bleibt dauerhaft bestehen und wird regelmäßig von
+`master` nachgezogen, damit er nicht wegdriftet.
+
+## Datenbank - entschieden: leeres Schema
+
+Eigene PostgreSQL-Instanz im Test-Stack, befüllt mit **Struktur ohne Zeilen**. Keine
+Kundendaten verlassen die Produktion.
+
+```bash
+# Struktur aus Prod ziehen (keine Zeilen)
+docker exec qrmaster-db pg_dump -U postgres --schema-only qrmaster > schema.sql
+
+# in die Test-DB einspielen
+docker exec -i qrmaster-test-db psql -U postgres -d qrmaster_test < schema.sql
+```
+
+Danach einen Testaccount anlegen - entweder über das Signup-Formular auf testmodul oder per
+`INSERT`.
+
+**Warum der Dump aus Prod und nicht aus Prisma:** `prisma/migrations` steht auf April 2026.
+Alles seitdem (Pulse-Spalten, `BARCODE`-Enum-Wert, ...) kam per Hand-SQL. Die Produktions-DB
+ist damit die einzige Stelle, die die aktuelle Struktur kennt.
+
+**Warum leer statt Kopie:** beim Tweet-Bot willst du wissen, welcher Testfall den Tweet
+ausgelöst hat. Mit Prod-Daten könnte es auch irgendein echter Kunde von vor Monaten gewesen sein.
+
+### Keine Migrationen - der Entrypoint muss überschrieben werden
+
+[docker/entrypoint.sh:5](docker/entrypoint.sh:5) führt bei **jedem** Container-Start
+`npx prisma migrate deploy` aus. Das widerspricht der Policy aus CLAUDE.md (Schema-Änderungen
+nur per Hand-SQL) und würde auf einer frischen Test-DB die 6 veralteten Migrationen anwenden -
+also ein Schema vom Stand April 2026 bauen, dem alle späteren SQL-Änderungen fehlen. Die App
+liefe dann in "column does not exist".
+
+Im Test-Override deshalb:
+
+```yaml
+web:
+  entrypoint: ["node", "server.js"]
+```
+
+Prod bleibt unverändert. Der Schema-Dump bringt die Tabelle `_prisma_migrations` ohnehin mit,
+inklusive der 6 als angewandt markierten Einträge - der Zustand ist also identisch zu Prod.
+
+**Separat zu klären (nicht Teil dieses Plans):** ob `prisma migrate deploy` langfristig auch
+aus dem Prod-Entrypoint verschwinden soll. Heute ist es dort ein No-Op, aber es ist eine
+scharfe Waffe, die bei einem versehentlich hinzugefügten Migrationsfile auf die Produktion
+losgeht.
+
+### Spätere Schema-Änderungen
+
+Ein SQL-Statement, das auf Test getestet wurde, wird auf Prod **erneut von Hand** ausgeführt -
+es gibt keinen automatischen Weg von Test nach Prod. Die Dateien in `sql/` sind der Ort dafür.
+
+## Aufwand
+
+| | |
+|---|---|
+| Cookie-Name verkabeln (6 Stellen) + Dockerfile/Compose | ~1 h |
+| `docker-compose.test.yml` + `robots.ts` an INDEXABLE koppeln | ~1 h |
+| `.env.test`, Secrets, Test-Keys besorgen | Timo |
+| Caddy-Block + erster Deploy | ~30 min |
+| DB-Variante B zusätzlich | +2-3 h für das Anonymisierungs-Skript |
+

+# Retention-Mails & CRO-Momente - Analyse
+
+Stand 27. Juli 2026. Grundlage: `src/lib/email.ts`, `src/app/(main)/api/cron/retention-emails/route.ts`, `src/components/marketing/PostDownloadPopup.tsx`, `src/app/(main)/(app)/create/page.tsx` sowie Offer Brief §10 und der Necessary-Beliefs-Doc.
+
+---
+
+## Teil 1 - Der 3/3-Moment: es gibt kein Popup
+
+Das Wichtigste zuerst, weil es kein Copy-Problem ist.
+
+Wenn ein Free-Nutzer den vierten dynamischen Code anlegen will, passiert laut `create/page.tsx` Zeile 456-458 Folgendes:
+
+```
+if (response.status === 403 && responseData.error === 'Limit reached') {
+  showToast(responseData.message || 'You have reached your plan limit.', 'error');
+  router.push('/pricing?reason=limit_reached');
+}
+```
+
+Drei Dinge gehen hier schief, in aufsteigender Schwere:
+
+**1. Roter Fehler-Toast.** Der Nutzer hat nichts falsch gemacht. Er hat das Produkt so benutzt, wie es gedacht ist, und bekommt dafür eine Fehlermeldung im gleichen Stil wie eine kaputte URL. Das ist keine Upgrade-Aufforderung, das ist eine Zurechtweisung.
+
+**2. Die Arbeit ist weg.** Der Nutzer hat Ziel-URL, Typ, Farben, vielleicht ein Logo eingegeben. Beim Redirect auf `/pricing` ist all das verloren. Wer danach upgradet, muss von vorne anfangen. Das ist der teuerste denkbare Zeitpunkt für Datenverlust: exakt in dem Moment, in dem die Kaufabsicht am höchsten ist.
+
+**3. Der Redirect ist ein Rauswurf.** Der Nutzer wollte einen QR-Code bauen und landet auf einer Preistabelle ohne Bezug zu dem, was er gerade tat. Kein Weg zurück, kein „so sieht dein Code aus, er ist nur noch nicht gespeichert".
+
+Aus dem Offer Brief §7: der Engpass ist **Perceived Likelihood**, nicht Preis und nicht Effort. Dieser Ablauf senkt genau die - er zeigt, dass das Produkt in einem kritischen Moment die eigene Arbeit wegwirft.
+
+### Was stattdessen hin muss
+
+Ein Modal, das **über** dem fertigen Code aufgeht, nicht statt ihm. Der Code bleibt im Hintergrund sichtbar. Vorschlag:
+
+> **Dein vierter Code ist fertig. Er braucht nur noch einen Platz.**
+>
+> Du nutzt alle 3 dynamischen Codes des Free-Plans. Dieser hier ist gebaut und wartet - du kannst ihn behalten oder einen bestehenden freigeben.
+>
+> [ Diesen Code mit Pro speichern - 9 € / Monat ]
+> [ Einen bestehenden Code ersetzen ]
+> [ Stattdessen als statischen Code herunterladen - kostenlos, läuft nie ab ]
+>
+> Deine 3 aktiven Codes laufen weiter, egal wie du dich entscheidest.
+
+Warum diese drei Optionen:
+
+- **Option 1** ist der Kauf, aber formuliert als „diesen konkreten Code retten", nicht als „Plan kaufen". Der Nutzer kauft eine Sache, die er gerade in der Hand hat.
+- **Option 2** ist die ehrliche Alternative innerhalb des Free-Plans. Sie kostet ein paar Conversions und kauft dafür Glaubwürdigkeit - Belief 5 aus dem Necessary-Beliefs-Doc: der sicherste Anbieter ist der, der offenlegt, was er kann und was nicht.
+- **Option 3** ist der Ausweg ohne Verlust. Ein statischer Code löst das Problem des Nutzers zu 60 % und kostet nichts, und die Zusage „läuft nie ab" ist verifiziert. Wer sie nimmt, ist nicht verloren - er hat gerade erlebt, dass das Produkt ihm nichts wegnimmt.
+
+Der letzte Satz ist Risk Reversal an genau der Stelle, wo die Kategorie ihren schlechtesten Ruf hat: das Abschalten bereits gedruckter Codes.
+
+---
+
+## Teil 2 - Die Retention-Mails
+
+Die Copy ist besser als der Durchschnitt. Absenderpersona ist da (Timo, Founder, Reply geht an einen Menschen), keine Ausrufezeichen-Orgie, konkrete Zahlen. Was fehlt, liegt eine Ebene tiefer.
+
+### Mail 1 - Tag 3, Aktivierung
+
+Betreff: `You haven't made one yet`
+Headline: `You haven't made one yet, {Name}. 3 days since signup · 0 QR codes created`
+
+Das ist die stärkste der drei. Der Betreff ist ein Pattern Interrupt in einem Posteingang voller „Tips & Tricks", und die Zeile `Your 3 free dynamic QR codes are still there. Unused.` ist Pointing statt Talking.
+
+Zwei Schwächen:
+
+**Der Betreff kann als Vorwurf gelesen werden.** „You haven't made one yet" mit Doppeldeutigkeit - ist das eine Beobachtung oder eine Rüge? Die Headline im Body löst es auf, der Betreff allein nicht. Alternative, gleiche Länge, ohne Vorwurfsrisiko: `Your 3 free codes are still sitting there`.
+
+**Es fehlt der Anlass.** Die Mail erklärt, *wie* man einen Code macht (drei Schritte), aber nicht, *wofür der Empfänger sich damals angemeldet hat*. Wenn beim Signup die Quelle bekannt ist - kam er über `/tools/google-review-qr-code`, über die Restaurant-Seite, über Bulk? -, dann gehört Schritt 01 personalisiert. „Paste your URL" ist die generischste denkbare Aufforderung an jemanden, der wegen Google-Reviews kam.
+
+### Mail 2 - Tag 7, Upgrade
+
+Betreff: `You're at the free limit` bzw. `You're 2 away from the free limit`
+Headline: `{n} of 3 free codes used, {Name}.`
+
+Hier ist der Trigger das Problem, nicht die Worte.
+
+**Die Mail feuert am Tag 7, unabhängig vom Verhalten.** Die Bedingung im Cron ist `createdAt < 7 Tage` und `qrCount > 0` und `plan = FREE`. Ein Nutzer mit **einem** Code bekommt eine Mail mit dem Betreff „You're 2 away from the free limit" - über ein Limit, das ihn nicht drückt und vielleicht nie drücken wird. Das ist eine Upgrade-Aufforderung an jemanden ohne Schmerz. Solche Mails trainieren Empfänger darauf, den Absender zu ignorieren, und der Absender ist hier der Gründer persönlich - das ist teurer Kredit, den man nicht für eine Fehlzündung ausgeben sollte.
+
+**Empfehlung: den Trigger vom Kalender aufs Verhalten umstellen.**
+
+| Zustand | Auslöser | Inhalt |
+|---|---|---|
+| 3 von 3 belegt | sobald erreicht, nicht Tag 7 | Limit-Mail wie jetzt, aber sofort im Moment der Relevanz |
+| 1-2 von 3 belegt | Tag 7 | keine Upgrade-Mail. Stattdessen: was die Scan-Daten des ersten Codes zeigen |
+| 3 von 3 und erster Code hat Scans | 3 Tage nach Limit | Upgrade mit den eigenen Zahlen des Nutzers als Beweis |
+
+Das dritte Szenario ist die eigentlich fehlende Mail. Nichts überzeugt einen Marketing-Manager so wie sein eigener erster Datenpunkt: „Dein Code auf dem Flyer hatte 47 Scans, die meisten dienstags zwischen 11 und 14 Uhr." Das ist Pointing in Reinform, und es kostet nichts außer der Query.
+
+**Und ein inhaltlicher Fehler.** Die Vergleichstabelle listet `CSV export: Free ✓ / Pro ✓`. Eine Zeile, in der beide Spalten identisch sind, ist in einer Upgrade-Tabelle wertlos - sie füllt Platz und verwässert die drei Zeilen, die tatsächlich einen Unterschied zeigen. Streichen.
+
+### Mail 3 - Tag 30
+
+Betreff: `{Name}, a month of QR codes - one upgrade worth making`
+Argument: Pro-Nutzer bereuen, das Branding nicht früher hinzugefügt zu haben.
+
+**Das Argument ist gut gebaut und nicht belegt.** Der Satz `The one thing I hear most from Pro users who switched after a few weeks: they wish they'd added their brand sooner` behauptet ein Muster aus Kundengesprächen. Wenn diese Gespräche stattgefunden haben: rein damit, am besten mit einem echten Zitat. Wenn nicht, ist das ein erfundenes Testimonial in indirekter Rede und verstößt gegen die Beweisregel aus dem Product Context („keine erfundenen Testimonials"). Bei einer Zielgruppe, die Bewertungsportale liest, ist das die teuerste Art von Satz.
+
+**Der Aufhänger ist außerdem der schwächere von zwei verfügbaren.** Branding ist ein Ästhetik-Argument. Nach 30 Tagen mit mehreren Codes hat der Nutzer etwas viel Stärkeres in der Hand: Scan-Daten. Der Tag-30-Anlass sollte der erste echte Report sein, nicht ein Logo-Feature. „Deine Codes wurden diesen Monat X-mal gescannt. Hier ist, was du noch nicht sehen kannst" - und dann Device- und Location-Breakdown als das, was Pro freischaltet. Das ist derselbe Kaufgrund, aber hergeleitet aus dem, was der Nutzer selbst erlebt hat.
+
+Das deckt sich mit Offer Brief §10, Option 1: auf Analytics-Tiefe metern statt auf Code-Anzahl. Diese Mail wäre die erste Stelle, an der man das testen kann, ohne das Pricing anzufassen.
+
+### Übergreifend: es fehlt die Mail nach dem ersten Scan
+
+Die Sequenz ist Tag 3, Tag 7, Tag 30 - drei Kalendertermine. Der wichtigste Moment im Lebenszyklus dieses Produkts kommt in keinem davon vor: **der erste Scan eines Codes.** Das ist der Augenblick, in dem aus einem Tool eine Messung wird und in dem das Versprechen der Positionierung zum ersten Mal einlöst. Eine Mail „Dein Code wurde gerade zum ersten Mal gescannt" hat einen Anlass, der nicht konstruiert ist, und braucht überhaupt kein Verkaufsargument.
+
+---
+
+## Teil 3 - Das Post-Download-Popup auf den Tool-Seiten
+
+Aktuell:
+
+> **Your QR code is downloading!**
+> Want to make it smarter - for free?
+>
+> - Edit the link anytime - QR stays the same
+> - See who scans, when & where
+> - Custom colors, logo & frames
+> - Free plan included - upgrade anytime for more
+>
+> [ Create Free Account ] / *No thanks, keep it static*
+
+### Was funktioniert
+
+Das Timing ist richtig: nach dem Download, nicht davor. Der Nutzer hat bekommen, wofür er kam - das Popup nimmt ihm nichts weg. Und `No thanks, keep it static` ist eine ehrliche Ablehn-Option ohne Beschämung, was in dieser Kategorie selten ist. Nicht anfassen.
+
+### Was nicht funktioniert
+
+**Die Headline sagt nichts.** `Your QR code is downloading!` ist eine Statusmeldung. Der Nutzer sieht den Download in seinem Browser, er braucht keine Bestätigung. Diese Zeile ist die prominenteste Fläche des Popups und verbraucht sie für eine Information, die der Nutzer schon hat.
+
+**Der Kernnutzen ist die dritte Zeile in einer Bullet-Liste.** `Edit the link anytime - QR stays the same` ist das gesamte Argument des Produkts, versteckt zwischen einem Icon und drei gleichgewichtigen Geschwistern. In einer Liste von vier gleich formatierten Punkten ist keiner davon wichtig.
+
+**Es fehlt der Anlass in diesem Moment.** Der Nutzer hat gerade einen **statischen** Code heruntergeladen. Der interessante Satz ist nicht „mach ihn schlauer", sondern die Konsequenz dessen, was er gerade getan hat: dieser Code ist ab jetzt festgelegt. Das ist kein Vorwurf und keine Drohung, das ist eine Tatsache über die Datei in seinem Download-Ordner - und exakt Belief 1 aus dem Necessary-Beliefs-Doc.
+
+**Es ist auf allen Tool-Seiten identisch.** Wer auf `/tools/google-review-qr-code` war, will Bewertungen. Wer auf `/tools/wifi-qr-code` war, will Gäste ins WLAN. Ein Popup, das beiden dasselbe sagt, spricht keinem von beiden.
+
+### Vorschlag
+
+> **Dieser Code zeigt jetzt für immer auf diese URL.**
+>
+> Das ist bei einem dauerhaften Link genau richtig. Falls sich das Ziel je ändert, brauchst du einen neuen Code und neues Druckmaterial.
+>
+> Ein kostenloses Konto gibt dir 3 dynamische Codes: gleiches Bild, Ziel jederzeit änderbar, jeder Scan gezählt.
+>
+> [ Kostenloses Konto anlegen - keine Karte ]
+> *Nein danke, statisch reicht*
+
+Struktur dahinter: P.I.G.-Opening auf eine Tatsache statt auf ein Feature, dann die Zugeständnis-Zeile („bei einem dauerhaften Link genau richtig") - das ist Offer Brief §9, die Konzession als Glaubwürdigkeits-Move -, dann erst der Mechanismus. Die Bullet-Liste entfällt komplett; drei gleichrangige Vorteile sind schwächer als ein Satz, der den einen benennt.
+
+Pro Tool-Seite variiert nur die erste Zeile:
+
+| Tool | Erste Zeile |
+|---|---|
+| Google Review | Dieser Code zeigt jetzt für immer auf dieses Google-Profil. |
+| WiFi | Dieser Code enthält jetzt dauerhaft dieses WLAN-Passwort. |
+| vCard | Dieser Code enthält jetzt dauerhaft diese Kontaktdaten. |
+| URL / Standard | Dieser Code zeigt jetzt für immer auf diese URL. |
+
+Die WiFi-Variante ist die stärkste der vier, weil sie einen Umstand benennt, den fast niemand vorher bedenkt: das Passwort steht in der gedruckten Datei. Wer es ändert, hat wertloses Material.
+
+---
+
+## Reihenfolge nach Wirkung pro Aufwand
+
+1. **Das 3/3-Modal bauen.** Momentan verliert das Produkt an der Stelle mit der höchsten Kaufabsicht die Arbeit des Nutzers. Das ist der einzige Punkt hier, der auch Entwicklungsarbeit ist und nicht nur Text.
+2. **Trigger der Tag-7-Mail auf Verhalten umstellen.** Query-Änderung im Cron, keine neue Infrastruktur.
+3. **Popup-Copy und Headline umstellen**, mit Variante pro Tool-Seite.
+4. **Die „erster Scan"-Mail** ergänzen - der einzige Anlass in der ganzen Sequenz, der nicht vom Kalender kommt.
+5. **Tag 30 auf Scan-Daten umbauen** statt Branding, und den unbelegten Pro-Nutzer-Satz entweder belegen oder streichen.

+# Blog-Keyword-Plan aus GSC (letzte 3 Monate, Stand 2026-08-03)
+
+Datenbasis: 1.001 Suchanfragen, 163 Seiten. Gesamt ~34k Impressionen, ~150 Klicks außerhalb der Homepage.
+
+## Kernbefund
+
+Das Problem ist **nicht fehlender Content, sondern Positionen 40–70**. Fast alle großen Cluster haben 0 Klicks bei hunderten Impressionen, weil sie auf Seite 4–7 stehen. Dazu kommt **Kannibalisierung**: mehrere Blogposts konkurrieren mit der Money-Page um dasselbe Keyword — und alle verlieren.
+
+Beispiel Tracking:
+
+| URL | Impr. | Position |
+|---|---|---|
+| /qr-code-tracking | 2.148 | 48,4 |
+| /blog/qr-code-tracking-guide-2025 | 67 | 79,4 |
+| /blog/trackable-qr-codes | 204 | 81,5 |
+| /blog/qr-code-analytics | 93 | 85,1 |
+| /guide/tracking-analytics | 1 | 91,0 |
+
+Fünf Seiten für ein Thema → keine rankt. Gleiches Muster bei Dynamic QR und Instagram.
+
+---
+
+## A) Zuerst verbessern (bestehende Posts, Position 20–45 = erreichbar)
+
+Diese sind am nächsten an Seite 1. Höchster ROI.
+
+**1. `/blog/free-vs-paid-qr-generator` — Position 31, 446 Impr., 1 Klick**
+Beste Blog-Position der Site. Keywords, die schon auf ~26 stehen:
+- `free vs paid qr code generator` (97 Impr., Pos. 26,7)
+- `free vs paid qr code generators` (78, Pos. 26,6)
+- `do you have to pay for qr codes` (42, Pos. 49) + 4 Varianten
+- `do qr codes cost money` (20)
+
+→ Ergänzen: FAQ-Block mit exakt diesen Frageformulierungen ("Do you have to pay for QR codes?", "Do QR codes cost money?"), Preisvergleichstabelle mit echten Zahlen der Wettbewerber, Update-Datum 2026.
+
+**2. `/blog/microsoft-teams-qr-code` — Position 14,4, 287 Impr., 0 Klicks**
+Position 14 mit 0 % CTR = Title/Meta-Problem, kein Ranking-Problem.
+- `microsoft teams qr code generator` (18 Impr., Pos. 9,6 — bereits Seite 1!)
+- `teams qr code generator` (12, Pos. 6,6), `teams qr code` (17, Pos. 27), `qr code for teams meeting` (6, Pos. 11)
+
+→ Title-Tag und Meta-Description neu schreiben (Jahreszahl, Nutzenversprechen), interne Verlinkung von /tools/teams-qr-code. Kein neuer Content nötig.
+
+**3. `/blog/best-qr-code-generator-2026` — Position 41, 55 Impr.**
+Wettbewerber-Cluster hat 1.173 Impr. gesamt, alles bei 0 Klicks:
+- `beaconstac` (96), `beaconstac qr code generator` (75), `beaconstac vs popl` (67), `beaconstac vs mobilo` (57), `popl vs beaconstac` (56), `blinq vs beaconstac` (42), `beaconstac alternative` (34)
+- `flowcode alternative` (51, Pos. 18,3 — nah dran), `flowcode competitors` (38, Pos. 29), `flowcode pricing` (21), `uniqode alternative` (24, Pos. 26)
+
+→ Vergleichstabelle mit Preisen pro Anbieter einbauen. Zusätzlich: die `X vs Y`-Queries (Beaconstac vs Popl/Mobilo/Blinq) sind reine Vergleichsintention ohne passende Seite — dafür Punkt B4.
+
+**4. `/blog/whatsapp-qr-code-generator` — Position 10,2, nur 33 Impr.**
+Steht auf Seite 1, bekommt aber kaum Impressionen — während `/tools/whatsapp-qr-code` bei 441 Impr. auf Position 55 hängt.
+- `whatsapp qr code generator` (211 Impr., Pos. 59,5), `whatsapp qr generator` (107, Pos. 66,5)
+
+→ Klassische Kannibalisierung. Blogpost auf Tool-Seite verlinken (Canonical prüfen), Blogpost als Ratgeber positionieren statt als Generator.
+
+---
+
+## B) Neue Blogposts (echte Nachfrage, keine passende Seite)
+
+**B1. Google Reviews — 1.331 Impr., 0 Klicks, kein einziger Blogpost**
+Größte inhaltliche Lücke. `/tools/google-review-qr-code` hat 1.752 Impr. bei Pos. 37,8 und 0,11 % CTR — komplett ohne Content-Support.

+
+→ **Post: "How to Create a Google Review QR Code (Free, 2026)"** — Schritt-für-Schritt inkl. Place-ID finden, Aufsteller-Templates, rechtliche Hinweise zum Review-Gating. Verlinkt hart auf das Tool.
+
+**B2. Location / Geo QR — 923 Impr., 0 Klicks, kein Blogpost**

+
+→ **Post: "Location QR Codes: Google Maps, GPS-Koordinaten & Apple Maps richtig verlinken"** — geo:-URI vs. Maps-Link, welches Format auf iOS/Android funktioniert. Dieses technische Detail sucht sonst niemand ordentlich.

+- `qr code coupon` (66), `qr code coupons` (56), `qr coupon` (50), `coupon qr code` (49), `qr coupons` (36), `qr code coupon redemption` (35), `qr code discount coupon` (22), `qr code coupon system` (5)
+
+→ **Post: "QR Code Coupons: Einlösung tracken & Missbrauch verhindern"** — Einmal-Codes, Redemption-Tracking, Ablaufdaten. `qr code coupon redemption` und `qr code coupon system` zeigen Intention über "erstellen" hinaus.

+**B4. Wettbewerbsvergleiche `X vs Y` — ~350 Impr., 0 Klicks**
+- `beaconstac vs popl` (67), `beaconstac vs mobilo` (57), `popl vs beaconstac` (56), `blinq vs beaconstac` (42), `bitly vs beaconstac qr codes` (18, Pos. 14,9!), `uniqode vs flowcode` (4), `flowcode vs qr code` (15)
+
+→ Deckt sich mit dem CLAUDE.md-Backlog (`/vs/`-Seiten). Ein Blogpost **"Beaconstac vs Popl vs Blinq vs QR Master: Digital Business Card & QR Vergleich 2026"** fängt mehrere dieser Queries gleichzeitig ab.
+
+**B5. Custom Design / Logo — 465 Impr., 0 Klicks**

+→ **Post: "Custom QR Codes mit Logo: Design-Regeln, die die Scanbarkeit nicht kaputt machen"** — Fehlerkorrektur-Level, Kontrastminimum, Logo-Größe max. 30 %, Farbkombis die scheitern. Klarer How-to-Intent, den die Tool-Seite nicht bedient.
+
+**B6. Bulk / Batch aus Excel & CSV — 402 Impr., aber bereits 2 Klicks + gute Positionen**
+- `bulk qr code generator in google sheets` (23, Pos. 38, **1 Klick**), `batch qr code generator from excel` (32, Pos. 41,8), `bulk qr code generator from excel` (3, Pos. 22, **1 Klick**), `bulk qr code generator excel` (18), `csv qr code generator` (13), `free bulk qr code generator excel` (14)
+
+→ **Post: "QR Codes aus Excel oder Google Sheets erzeugen (Schritt für Schritt)"** — sehr konkreter Workflow-Intent, konvertiert nachweislich schon jetzt.
+
+**B7. Feedback QR — 349 Impr., 0 Klicks**
+`/use-cases/feedback-qr-codes`: 385 Impr., Pos. 60,3.
+- `qr code feedback` (165), `qr code for feedback` (93), `feedback qr code` (62), `qr code for customer feedback` (23), `create qr code for feedback` (21)
+
+→ **Post: "Kundenfeedback per QR Code sammeln: Formulare, Response-Raten, Platzierung"**
+
+---
+
+## C) Konsolidieren statt neu schreiben
+
+**Tracking-Cluster (2.371 Impr., 0 Klicks)** — 5 Seiten kannibalisieren sich (Tabelle oben).
+→ `/blog/trackable-qr-codes`, `/blog/qr-code-analytics`, `/guide/tracking-analytics` per 301 auf `/blog/qr-code-tracking-guide-2025` zusammenlegen. Dieser eine Post wird der Support-Content für `/qr-code-tracking`.
+Zielkeywords: `qr code tracking` (190), `tracking qr code` (158), `qr tracking` (145), `how to track qr code` (118), `track qr code scans` (92), `qr code scan tracking` (88)
+Bereits stark: `how to track qr code scans from a print campaign` (43 Impr., **Pos. 9,9**) — als eigenes H2 ausbauen.
+
+**Dynamic-QR-Cluster (3.598 Impr., 0 Klicks — größtes Volumen der Site)**
+`/dynamic-qr-code-generator` hat 4.147 Impr. bei Pos. 45,5 und **0,02 % CTR**.
+Support-Posts existieren, ranken aber ohne Impressionen (Indexierungsproblem):
+- `/blog/static-vs-dynamic-qr-code` (Pos. 3, aber nur 1 Impr.)
+- `/blog/dynamic-vs-static-qr-codes` (Pos. 5, 1 Impr.) ← Duplikat des vorigen
+- `/blog/convert-static-to-dynamic-qr-code` (Pos. 3,5, 2 Impr.)
+- `/guide/dynamic-qr-code-best-practices` (Pos. 50)
+
+→ Die beiden static-vs-dynamic-Posts sind faktisch dieselbe Seite. Zusammenlegen, dann alle drei prominent von der Money-Page verlinken. Kein neuer Post nötig.
+
+**Instagram** — `/tools/instagram-qr-code` (794 Impr., Pos. 33,7) vs. `/blog/instagram-qr-code-generator` (11 Impr., Pos. 73,4). Blogpost zu How-to umschreiben oder konsolidieren.

+
+Erstellt: 2026-08-04 · Datenbasis: GSC-Export 2026-08-03 (letzte 3 Monate)
+Zugeschnitten auf **wenige Stunden pro Woche** — jeder Schritt ist einzeln abschließbar.
+
+Ausgangslage: ~34.000 Impressionen, ~150 Klicks außerhalb der Homepage. Kein Sichtbarkeits-, sondern ein Positions- und Konsolidierungsproblem.
+

+
+## REVISION 2026-08-04 — nach Code- und Live-Prüfung
+
+Beim Umsetzen von Phase 1 hat sich die Ausgangslage als anders herausgestellt als aus den reinen GSC-Daten ableitbar. Drei Befunde, die den Plan verändern.
+
+### Befund 1: Kaputter Title (behoben)
+
+`/blog/qr-code-tracking-guide-2025` hatte rohes HTML im `title`-Feld:
+
+```
+title: '<a href="/qr-code-tracking" class="...">QR Code Tracking</a>: Complete Guide 2026'
+```
+
+Live ausgeliefert wurde daraus im `<title>`-Tag, in der H1, in `og:title` und `twitter:title`:

+
+**Das erklärt Position 79,4 vollständig.** Kein Content-, kein Kannibalisierungsproblem — ein unbrauchbares Snippet. Einzelvorkommen, alle anderen Titles sind sauber. Behoben in `src/lib/blog-data.ts:1160`.

+Die GSC-Positionen dieser URLs sind damit **historisch** — die Redirects waren nur die letzten ~3,5 Wochen des Auswertungsfensters aktiv. Die Phase-1.1-Tabelle weiter unten ist insoweit überholt.
+
+**Konsequenz:** Nicht `/blog/qr-code-tracking-guide-2025` zum Ziel machen, wie ursprünglich geplant. Die bestehende Architektur ist `/learn/[pillar]` als Hub. Dieser Struktur folgen, keine dritte parallel aufmachen.
+
+### Befund 3: Der Learn-Hub hält die Kannibalisierung am Leben
+
+`/learn/tracking` listet und verlinkt **alle fünf** konkurrierenden Tracking-Artikel gleichzeitig — inklusive `/blog/qr-code-analytics`, das eine 301-Quelle ist. Der Hub ist damit nicht die Lösung, sondern der Motor: Er hält jeden Artikel im Index und intern verlinkt, statt Signale zu bündeln.
+
+Zusätzlich behoben:
+
+- **Footer** verlinkte sitewide auf `/guide/tracking-analytics` und `/guide/qr-code-best-practices` — beides 301-Quellen. Jede Seite der Site leitete Linkkraft durch eine Weiterleitung. → jetzt `/learn/tracking` und `/learn/basics` (`src/components/ui/Footer.tsx:88-89`)
+- **IndexNow** meldete aktiv die drei `/guide/*`-URLs an Suchmaschinen, also Redirect-Quellen. → jetzt die `/learn/*`-Pillars (`src/lib/indexnow.ts:125-130`)
+
+### Offen aus dieser Runde
+
+- [ ] `/learn/tracking` entrümpeln: nur noch auf die eine überlebende Tracking-Seite verlinken, nicht auf alle fünf
+- [ ] `/blog/trackable-qr-codes` (204 Impr., Pos. 81,5) ist **nicht** weitergeleitet und lebt weiter → 301 auf den Guide
+- [ ] `src/app/(main)/guide/*/page.tsx` existieren noch als Komponenten mit Self-Canonical, obwohl der Redirect greift → Dead Code entfernen
+- [ ] Drei FAQ-Antworten in `industry-pages.ts` (Zeilen 102, 375, 735) und `growth-pages.ts:473` verlinken auf `/blog/qr-code-restaurant-menu` → auf `/restaurants` umhängen
+
+**Erst diese Punkte, dann Phase 2.** Die Reihenfolge im Plan bleibt sonst gültig.
+
+---
+
+## Wichtige Korrektur vorab: Intent-Check vor Snippet-Rewrites
+
+Ich hatte empfohlen, die `/qr-code-for/`-Seiten mit Position < 20 und 0 % CTR per Title-Rewrite zu fixen. Beim Prüfen der Seiten stimmt das **nur zum Teil**. Die Meta-Titles sind bereits gut geschrieben:
+
+> `barbershops` → „QR Codes for Barbershops: Bookings & Reviews"
+> `cinemas` → „QR Codes for Cinemas: Tickets & Loyalty"
+
+Das Problem liegt woanders. Beispiel `/qr-code-for/barbershops` (327 Impr., Position 9,8, 4 Klicks) — die tatsächlichen Suchanfragen:
+
+| Query | Impr. | Pos. |
+|---|---|---|
+| short code for barbershops | 16 | 21,8 |
+| qr barber | 13 | 8,9 |
+| short code for barber shops | 6 | 16,3 |
+| barber+scan | 5 | 9,6 |
+| barcode grooming | 4 | 11,0 |
+| short code for barber shop | 4 | 26,0 |
+
+Das Muster `short code for X` zieht sich durch: `short code for barbers`, `for yoga studios`, `for cinemas`, `for bars`, `for nail bars`, `for theaters`, `for barbershop` — zusammen rund 60 Impressionen. Wer „short code for barbershops" sucht, will mit hoher Wahrscheinlichkeit einen **SMS-Short-Code**, keinen QR-Code. Diese Impressionen sind mit keinem Title der Welt klickbar.
+
+**Konsequenz für den Plan:** Vor jedem Rewrite die Queries der Einzelseite prüfen. Nur Seiten anfassen, deren Top-Queries echte QR-Intention haben. Das kostet pro Seite zwei Minuten und verhindert, dass Phase 2 zu Beschäftigungstherapie wird.
+
+---
+
+## Phase 0 — Messpunkt setzen (30 Min, einmalig)
+
+Ohne Baseline lässt sich später nicht sagen, ob etwas gewirkt hat.
+
+- [ ] GSC-Export von heute unter `/seo-baseline/2026-08-03/` im Repo ablegen
+- [ ] Vier Zahlen notieren: Gesamtklicks, Gesamtimpressionen, Ø-Position, Anzahl Keywords auf Position < 10
+- [ ] Kalendereintrag: gleicher Export am **2026-11-03** (Google braucht 6–10 Wochen, vorher ist jede Bewertung Rauschen)
+
+**Erfolgskriterium:** Datei liegt im Repo.
+
+---
+
+## Phase 1 — Kannibalisierung auflösen (Wochen 1–2)
+
+Höchster Hebel im ganzen Plan, weil kein neuer Content nötig ist. Fünf Seiten konkurrieren um das Tracking-Thema, keine rankt.
+
+### 1.1 Tracking-Cluster zusammenlegen (~2 Std.)
+
+| URL | Impr. | Pos. | Aktion |
+|---|---|---|---|
+| `/qr-code-tracking` | 2.148 | 48,4 | **bleibt** — Money-Page |
+| `/blog/qr-code-tracking-guide-2025` | 67 | 79,4 | **bleibt** — wird der eine Ratgeber |
+| `/blog/trackable-qr-codes` | 204 | 81,5 | 301 → Guide |
+| `/blog/qr-code-analytics` | 93 | 85,1 | 301 → Guide |
+| `/guide/tracking-analytics` | 1 | 91,0 | 301 → Guide |
+
+- [ ] Die besten Absätze aus den drei Seiten in den Guide übernehmen, bevor umgeleitet wird
+- [ ] Redirects in `next.config.mjs` eintragen
+- [ ] Guide umbenennen: `qr-code-tracking-guide-2025` → Jahreszahl raus oder auf 2026 (Slug-Änderung nur mit Redirect)
+- [ ] Eigenes H2 für `how to track qr code scans from a print campaign` — steht bereits auf **Position 9,9** bei 43 Impressionen
+- [ ] Wechselseitige Verlinkung Guide ↔ `/qr-code-tracking`
+
+**Erfolgskriterium:** Eine URL pro Suchintention. `/qr-code-tracking` unter Position 30 bis November.
+
+### 1.2 Static-vs-Dynamic-Duplikate mergen (~1 Std.)
+
+`/blog/static-vs-dynamic-qr-code` (Pos. 3, 1 Impr.) und `/blog/dynamic-vs-static-qr-codes` (Pos. 5, 1 Impr.) sind faktisch dieselbe Seite. Beide ranken top und bekommen zusammen 2 Impressionen — klassisches Zeichen dafür, dass Google beide kennt und keiner traut.
+
+- [ ] Inhalte in **eine** URL zusammenführen, die andere per 301 darauf
+- [ ] Zusammen mit `/blog/convert-static-to-dynamic-qr-code` (Pos. 3,5) und `/guide/dynamic-qr-code-best-practices` (Pos. 50) prominent von `/dynamic-qr-code-generator` verlinken
+
+**Warum das zählt:** `/dynamic-qr-code-generator` hat mit 4.147 Impressionen das größte Volumen der Site — bei Position 45,5 und 0,02 % CTR.
+
+### 1.3 Instagram entzerren (~30 Min)
+
+`/tools/instagram-qr-code` (794 Impr., Pos. 33,7) vs. `/blog/instagram-qr-code-generator` (11 Impr., Pos. 73,4).
+
+- [ ] Blogpost auf How-to-Intent umschreiben („So erstellst du…") oder konsolidieren, damit er nicht mehr um dasselbe Keyword kämpft
+
+---
+
+## Phase 2 — Snippets mit Intent-Check (Woche 3, ~2 Std.)
+
+Nur Seiten mit Position < 20, CTR < 3 % **und** passender Query-Intention.
+
+**Kandidaten mit belegbar richtiger Intention:**
+
+- [ ] `/blog/microsoft-teams-qr-code` — 287 Impr., **Position 14,4, 0 Klicks**. Queries sind sauber: `microsoft teams qr code generator` (Pos. 9,6), `teams qr code generator` (Pos. 6,6), `qr code for teams meeting` (Pos. 11). Klarster Einzelfall der Site.
+- [ ] `/tools/teams-qr-code` — 489 Impr., Pos. 13,6, CTR 2,45 %
+- [ ] `/tools/call-qr-code-generator` — 119 Impr., Pos. 18,9, 0 Klicks
+- [ ] `/learn` — 486 Impr., Pos. 13,3, CTR 1,65 %
+
+**Erst nach Query-Prüfung anfassen:** `/qr-code-for/cinemas` (168 Impr., Pos. 16), `/qr-code-for/airports` (162, Pos. 10,6), `/qr-code-for/yoga-studios`, `/qr-code-for/art-galleries`, `/qr-code-for/catering`, `/qr-code-for/car-dealerships`.
+
+Prüfweg: GSC → Seiten → URL wählen → Tab „Suchanfragen". Enthalten die Top-3-Queries `short code`, `barcode` oder Branchenbegriffe ohne QR-Bezug, ist die Seite kein Snippet-Fall.
+
+Titles und Descriptions liegen zentral in `src/lib/industry-pages.ts` (Felder `metaTitle`, `metaDescription`) — kein Anfassen einzelner Routen nötig.
+
+**Erfolgskriterium:** Teams-Post von 0 auf messbare Klicks. Alles andere ist Bonus.
+
+---
+
+## Phase 3 — Aufräumen (Woche 4, ~1 Std.)
+
+Nicht die 53 Branchenseiten löschen — die ranken mit Ø Position 20,4 am besten von allen Content-Typen. Tot ist etwas anderes:
+
+| Bereich | Seiten | Impr. | Klicks | Ø Pos. | Vorschlag |
+|---|---|---|---|---|---|
+| `/de/*` | 13 | 194 | 0 | 31,0 | Entscheiden: ausbauen oder deindexieren |
+| `/guide/*` | 2 | 15 | 0 | 70,6 | In `/blog/` überführen (siehe 1.1) |
+| `/compare/*` | 1 | 31 | 0 | 50,6 | Prüfen, ob es die Route noch braucht |
+| `/qr-code-erstellen` | 1 | 264 | 2 | 72,5 | Deutsche Seite ohne DE-Strategie — bündeln mit `/de/*` |
+
+Die DE-Frage ist eine Entscheidung, keine Aufgabe: 13 Seiten mit 0 Klicks binden Crawl-Budget. Entweder eine echte deutsche Sektion mit hreflang, oder weg.
+
+---
+
+## Phase 4 — Neue Posts, einer pro Woche (ab Woche 5)
+
+Reihenfolge nach Impressionen ohne passende Seite. Jeweils ein Post, dann weiter.
+
+| Woche | Post | Nachfrage | Zielseite, die profitiert |
+|---|---|---|---|
+| 5 | Google Review QR Code erstellen (inkl. Place-ID) | 1.331 Impr. | `/tools/google-review-qr-code` (1.752 Impr., Pos. 37,8) |
+| 6 | QR Codes aus Excel & Google Sheets | 402 Impr., **konvertiert bereits** | `/bulk-qr-code-generator` |
+| 7 | Location-QR: Maps, GPS, geo:-URI auf iOS vs. Android | 923 Impr. | `/tools/geolocation-qr-code` (Pos. 62,8) |
+| 8 | Custom QR mit Logo ohne Scanbarkeitsverlust | 465 Impr. | `/custom-qr-code-generator` |
+| 9 | QR-Coupons: Einlösung tracken, Missbrauch verhindern | 495 Impr. | `/use-cases/coupon-qr-codes` |
+| 10 | Beaconstac vs Popl vs Blinq vs QR Master | ~350 Impr., hohe Kaufintention | `/alternatives/*` |
+| 11 | Kundenfeedback per QR sammeln | 349 Impr. | `/use-cases/feedback-qr-codes` |
+
+Jeder Post: Verlinkung zur Money-Page rein **und** raus, Aufnahme in `public/llms.txt`, Eintrag im Sitemap-Lauf.
+
+**Woche 6 zuerst ziehen, falls Zeit knapp wird** — `bulk qr code generator in google sheets` und `bulk qr code generator from excel` haben als einzige Nicht-Brand-Keywords bereits Klicks geliefert. Bewiesene Konversion schlägt großes Volumen.
+
+---
+
+## Phase 5 — Daten-Asset (ab Woche 12, größerer Block)
+
+Aggregierte, anonymisierte Scan-Daten aus QRMaster als Studie: Scan-Zeitpunkte über den Tag, Device-Splits, wie oft dynamische Codes nach dem Druck tatsächlich geändert werden, Abbruchraten.
+
+**Realitätscheck vorab:** `/blog/qr-code-scan-statistics-2026` existiert bereits — Position 38,7, **3 Impressionen**. Ein Daten-Asset rankt nicht, weil es eines ist. Ohne Verteilung passiert nichts.
+
+- [ ] Bestehende Statistik-Seite als Basis nehmen statt neu anzulegen
+- [ ] Echte Zahlen aus der DB, Methodik sichtbar dokumentieren, Stichprobengröße nennen
+- [ ] Eigene Grafiken statt Fremdquellen
+- [ ] Erst danach: aktiv verteilen (Reddit, Branchennewsletter, HARO-artige Anfragen)
+
+Der Wert liegt im Zitiertwerden durch LLMs und in Backlinks, nicht im direkten Ranking. Entsprechend bewerten.
+
+---
+
+## Was dieser Plan bewusst nicht enthält
+
+**Crypto-Cluster** (765 Impr.) — rankt vergleichsweise gut (`usdt qr code generator` Pos. 13, 2 Klicks), monetarisiert aber schwach.
+
+**Internationale Streuung** — `system qr dla hoteli` (PL), `qr kütüphane` (TR), `куар мастер` (RU). Ohne lokalisierte Seiten nicht adressierbar, siehe DE-Entscheidung in Phase 3.
+
+**E-E-A-T-Maßnahmen** — `/authors/timo` existiert bereits (Position 6,4) und hat für sich genommen nichts bewegt. Kein weiterer Aufwand nötig.
+
+**Alles, was „schnell rankt"** — Phase 1 ist der schnellste Effekt im Plan, und auch der braucht 6–10 Wochen bis zur Messbarkeit.
+
+---
+
+## Nächster Schritt
+
+Phase 1.1 (Tracking-Konsolidierung). Zwei Stunden, kein neuer Text, betrifft 2.371 Impressionen.

+# Barcode Encoding Algorithms: EAN-13 & Code 128 Checksum Math from Scratch in JavaScript
+
+Long before 2D QR codes dominated digital marketing, one-dimensional (1D) linear barcodes—such as **EAN-13** in retail products and **Code 128** in logistics and shipping—revolutionized inventory automation.
+
+Building a **free barcode generator** or an **ean code generator** requires understanding that barcode scanner guns and camera libraries do not "guess" numbers from images; they decode precise binary bit patterns (bars and spaces) and verify mathematical **checksums** (Modulo 10 for EAN-13; Modulo 103 for Code 128).
+
+In this deep computer science guide, we will examine the bit pattern structures of EAN-13 and Code 128, derive their checksum formulas, and implement a pure TypeScript **barcode code generator** without any external npm dependencies.
+
+---
+
+## 1. Deconstructing EAN-13 Retail Barcode Encoding
+
+An **EAN-13** (European Article Number) barcode produced by an **ean code generator** encodes exactly 13 numeric digits:
+- **First 2–3 digits**: Country Prefix (e.g., `400–440` for Germany, `000–019` for US/Canada).
+- **Next 4–5 digits**: Manufacturer Identification Code.
+- **Next 4–5 digits**: Unique Item / Product Code.
+- **13th Digit**: Mathematical **Modulo 10 Checksum Digit**.
+
+```
+  Country  Manufacturer   Product   Check
+   ┌──┴──┐   ┌────┴────┐ ┌───┴───┐   ┌┴┐
+   4 0 0 1 2 3 4 5 6 7 8 9 5
+```
+
+### The EAN-13 Modulo 10 Checksum Formula
+To compute the 13th check digit for a 12-digit input in an **ean code generator**:
+
+1. Sum all digits in **odd-numbered positions** (1st, 3rd, 5th, 7th, 9th, 11th).
+2. Sum all digits in **even-numbered positions** (2nd, 4th, 6th, 8th, 10th, 12th) and multiply by 3.
+3. Add the two sums together.
+4. The check digit is the number required to reach the next multiple of 10:
+
+$$\text{Check Digit} = (10 - (\text{Total Sum} \pmod{10})) \pmod{10}$$
+
+### Checksum Example Calculation:
+Take the 12-digit string `400123456789`:
+- Odd sum: $4 + 0 + 2 + 4 + 6 + 8 = 24$
+- Even sum: $(0 + 1 + 3 + 5 + 7 + 9) \times 3 = 25 \times 3 = 75$
+- Total: $24 + 75 = 99$
+- Check digit: $(10 - (99 \pmod{10})) \pmod{10} = (10 - 9) \pmod{10} = 1$
+- Final 13-digit EAN-13 code: `4001234567891`
+
+---
+
+## 2. Deconstructing Code 128 High-Density Barcodes
+
+While EAN-13 is strictly numeric, a **code 128 barcode generator** creates high-density alphanumeric barcode formats capable of encoding all 128 ASCII characters (uppercase/lowercase letters, digits, punctuation, and control codes).
+
+### Code 128 Structure
+A Code 128 **qr barcode** structure consists of:
+1. **Start Character**: `Start A` (103), `Start B` (104), or `Start C` (105).
+2. **Data Symbol Characters**: Each character is represented by 11 modules composed of 3 bars and 3 spaces.
+3. **Check Character**: Modulo 103 checksum value.
+4. **Stop Character**: 13-module pattern (`1100011101011`).
+
+### The Code 128 Modulo 103 Checksum Formula
+
+$$\text{Checksum Value} = \left( \text{Start Value} + \sum_{i=1}^{N} (i \times \text{Symbol Value}_i) \right) \pmod{103}$$
+
+---
+
+## 3. Pure TypeScript Barcode Engine (No External Dependencies)
+
+Let's build a standalone TypeScript module (`src/services/barcodeEngine.ts`) for a **free barcode generator** that computes EAN-13 checksums and renders a vector SVG **print barcode**.
+
+### `src/services/barcodeEngine.ts`
+
+```typescript
+export class BarcodeEngine {
+  /**
+   * Computes the Modulo 10 Checksum digit for a 12-digit EAN string in an ean code generator.
+   */
+  public static calculateEAN13Checksum(digits12: string): number {
+    if (!/^\d{12}$/.test(digits12)) {
+      throw new Error('EAN-13 input must be exactly 12 numeric digits.');
+    }
+
+    let oddSum = 0;
+    let evenSum = 0;
+
+    for (let i = 0; i < 12; i++) {
+      const digit = parseInt(digits12[i], 10);
+      if (i % 2 === 0) {
+        oddSum += digit;
+      } else {
+        evenSum += digit;
+      }
+    }
+
+    const totalSum = oddSum + evenSum * 3;
+    const remainder = totalSum % 10;
+    return remainder === 0 ? 0 : 10 - remainder;
+  }
+
+  /**
+   * EAN-13 Binary Bit Patterns for L, G, and R encodings.
+   */
+  private static L_PATTERNS = [
+    '0001101', '0011001', '0010011', '0111101', '0100011',
+    '0110001', '0101111', '0111011', '0110111', '0001011'
+  ];
+
+  private static R_PATTERNS = [
+    '1110010', '1100110', '1101100', '1000010', '1011100',
+    '1001110', '1010000', '1000100', '1001000', '1110100'
+  ];
+
+  /**
+   * Generates a crisp vector SVG string for an EAN-13 barcode.
+   */
+  public static generateEAN13SVG(digits12: string): string {
+    const checkDigit = this.calculateEAN13Checksum(digits12);
+    const fullEan13 = digits12 + checkDigit.toString();
+
+    // Structural guard and center patterns
+    const GUARD_START = '101';
+    const GUARD_CENTER = '01010';
+    const GUARD_END = '101';
+
+    let bitPattern = GUARD_START;
+
+    // Encode Left 6 Digits (using L-Patterns for simplicity)
+    for (let i = 1; i <= 6; i++) {
+      const digit = parseInt(fullEan13[i], 10);
+      bitPattern += this.L_PATTERNS[digit];
+    }
+
+    bitPattern += GUARD_CENTER;
+
+    // Encode Right 6 Digits (using R-Patterns)
+    for (let i = 7; i <= 12; i++) {
+      const digit = parseInt(fullEan13[i], 10);
+      bitPattern += this.R_PATTERNS[digit];
+    }
+
+    bitPattern += GUARD_END;
+
+    // Render SVG
+    const moduleWidthPx = 3;
+    const heightPx = 120;
+    const totalWidthPx = bitPattern.length * moduleWidthPx + 40; // 40px margin
+
+    let svgPaths = '';
+    for (let i = 0; i < bitPattern.length; i++) {
+      if (bitPattern[i] === '1') {
+        const x = 20 + i * moduleWidthPx;
+        svgPaths += `<rect x="${x}" y="10" width="${moduleWidthPx}" height="${heightPx - 30}" fill="#000000" />`;
+      }
+    }
+
+    // Add human-readable numbers text below bars
+    const textSvg = `<text x="${totalWidthPx / 2}" y="${heightPx - 5}" font-family="monospace" font-size="16" text-anchor="middle">${fullEan13}</text>`;
+
+    return `
+<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 ${totalWidthPx} ${heightPx}" width="${totalWidthPx}" height="${heightPx}">
+  <rect width="100%" height="100%" fill="#FFFFFF" />
+  ${svgPaths}
+  ${textSvg}
+</svg>`.trim();
+  }
+}
+```
+
+---
+
+## 4. Verification & Testing
+
+Let's write a unit test to verify checksum calculation and SVG rendering output.
+
+```typescript
+import { BarcodeEngine } from '../src/services/barcodeEngine';
+
+describe('BarcodeEngine', () => {
+  test('should correctly compute EAN-13 Modulo 10 Checksum', () => {
+    // 400123456789 -> Check digit should be 1
+    const check = BarcodeEngine.calculateEAN13Checksum('400123456789');
+    expect(check).toBe(1);
+  });
+
+  test('should generate valid vector SVG string', () => {
+    const svg = BarcodeEngine.generateEAN13SVG('400123456789');
+    expect(svg).toContain('<svg');
+    expect(svg).toContain('4001234567891'); // Includes computed check digit
+    expect(svg).toContain('</svg>');
+  });
+});
+```
+
+---
+
+## Conclusion
+
+Understanding the binary bit patterns and mathematical checksum algorithms behind 1D barcodes allows developers to build a fast **free barcode generator** without relying on heavy external dependencies.

+
+# Building a High-Performance Custom QR Code Generator API with Node.js & Vector SVG
+
+QR codes have evolved from simple black-and-white square grids into essential digital-to-physical bridges. Whether you are building a **custom qr code generator** for an application, creating a **qr code generator online** for ticket barcodes, or building an internal microservice to **create a qr code from a link**, building your own API gives you total control over styling, performance, data privacy, and branding.
+
+In this deep-dive guide, we will build a production-ready, high-performance REST API in Node.js and Express that generates vector SVG and high-density PNG QR codes on the fly. We will also explore the math behind Reed-Solomon error correction, quiet zones, color contrast ratios, and how to optimize a **free custom qr code generator** for crisp printing.
+
+---
+
+## 1. Understanding QR Code Architecture & Error Correction
+
+Before writing any code, it is critical to understand how a **custom qr code generator** stores data and why vector graphics (SVG) are vastly superior to raster images (PNG/JPEG) for print media.
+
+### The QR Code Grid Structure
+A QR code is a two-dimensional matrix barcode consisting of:
+1. **Finder Patterns**: The three large squares located at the top-left, top-right, and bottom-left corners. Cameras use these to detect the barcode's orientation and scale.
+2. **Alignment Patterns**: Smaller squares (found in Version 2 and larger) that correct for non-linear distortion when a camera scans a curved surface.
+3. **Timing Patterns**: Alternating black and white modules connecting the finder patterns to establish the matrix coordinate grid size.
+4. **Format Information**: Modules storing the error correction level and the mask pattern used.
+5. **Data & Error Correction Codewords**: The actual payload (URL link, text, JSON) mixed with Reed-Solomon redundancy blocks.
+
+### Reed-Solomon Error Correction Levels
+QR codes use **Reed-Solomon Error Correction**, allowing damaged, dirty, or obscured codes to remain fully scannable:
+
+| Level | Error Recovery Capacity | Recommended Use Case |
+|---|---|---|
+| **L (Low)** | ~7% of codewords restored | Minimal data size, clean digital screens |
+| **M (Medium)** | ~15% of codewords restored | Standard marketing URLs, digital displays |
+| **Q (Quartile)** | ~25% of codewords restored | Industrial packaging, outdoor signage |
+| **H (High)** | ~30% of codewords restored | Embedding brand logos in a **custom qr code generator** |
+
+*Rule of thumb:* When embedding custom logos or high-contrast graphics in the center of a QR code, always enforce **Level H** so the remaining 70% of un-obscured modules provide 100% data integrity.
+

+
+## 2. Why SVG Vector Output Matters for Developers
+
+Raster formats like PNG or JPEG store pixels. If a 300x300 pixel PNG QR code is printed on a large 2-meter billboard, the square modules become blurry and pixelated, leading to scanner camera read failures.
+
+Vector SVG (`Scalable Vector Graphics`) defines QR modules as crisp mathematical paths (`<path d="M..."/>` or `<rect x="..." y="..."/>`). SVG files:
+- Scale infinitely to any print dimension (from business cards to stadium billboards) without loss of crispness.
+- Have a tiny file footprint (typically < 2 KB per code).
+- Allow programmatic CSS styling of foreground, background, and finder pattern colors.
+
+---
+
+## 3. Step-by-Step API Implementation
+
+Let's build a Node.js API with Express that accepts JSON payloads or URL query parameters and streams vector SVG or PNG outputs to **create a qr code from a link**.
+
+### Step 3.1: Project Setup & Dependencies
+
+Initialize a new Node.js project and install the required dependencies:
+
+```bash
+mkdir qr-code-api
+cd qr-code-api
+npm init -y
+npm install express qrcode cors helmet express-rate-limit dotenv
+npm install --save-dev typescript @types/node @types/express @types/cors ts-node-dev
+```
+
+Initialize TypeScript configuration (`tsconfig.json`):
+
+```json
+{
+  "compilerOptions": {
+    "target": "ES2022",
+    "module": "NodeNext",
+    "moduleResolution": "NodeNext",
+    "outDir": "./dist",
+    "rootDir": "./src",
+    "strict": true,
+    "esModuleInterop": true,
+    "skipLibCheck": true
+  },
+  "include": ["src/**/*"]
+}
+```
+
+---
+
+### Step 3.2: Creating the QR Generator Core Engine
+
+Create `src/services/qrEngine.ts`. This service handles matrix generation, error correction mapping, and SVG DOM construction.
+
+```typescript
+import QRCode, { QRCodeRenderersOptions } from 'qrcode';
+
+export interface QROptions {
+  text: string;
+  errorCorrectionLevel?: 'L' | 'M' | 'Q' | 'H';
+  width?: number;
+  margin?: number;
+  colorDark?: string;
+  colorLight?: string;
+  format?: 'svg' | 'png' | 'utf8';
+}
+
+export class QREngine {
+  /**
+   * Generates a scalable vector SVG QR code string.
+   */
+  public static async generateSVG(options: QROptions): Promise<string> {
+    const {
+      text,
+      errorCorrectionLevel = 'M',
+      margin = 4,
+      colorDark = '#000000',
+      colorLight = '#FFFFFF'
+    } = options;
+
+    const qrOptions: QRCodeRenderersOptions = {
+      errorCorrectionLevel,
+      margin,
+      color: {
+        dark: colorDark,
+        light: colorLight
+      }
+    };
+
+    try {
+      const svgString = await QRCode.toString(text, {
+        ...qrOptions,
+        type: 'svg'
+      });
+      return svgString;
+    } catch (err) {
+      throw new Error(`Failed to generate SVG QR code: ${(err as Error).message}`);
+    }
+  }
+
+  /**
+   * Generates a high-density PNG buffer for binary image response.
+   */
+  public static async generatePNGBuffer(options: QROptions): Promise<Buffer> {
+    const {
+      text,
+      errorCorrectionLevel = 'H',
+      width = 600,
+      margin = 4,
+      colorDark = '#000000',
+      colorLight = '#FFFFFF'
+    } = options;
+
+    const qrOptions: QRCodeRenderersOptions = {
+      errorCorrectionLevel,
+      width,
+      margin,
+      color: {
+        dark: colorDark,
+        light: colorLight
+      }
+    };
+
+    try {
+      const buffer = await QRCode.toBuffer(text, {
+        ...qrOptions,
+        type: 'png'
+      });
+      return buffer;
+    } catch (err) {
+      throw new Error(`Failed to generate PNG QR buffer: ${(err as Error).message}`);
+    }
+  }
+}
+```
+
+---
+
+### Step 3.3: Building the Express REST Controller & API Endpoints
+
+Create `src/app.ts` to set up rate limiting, CORS, input validation, and REST route handlers.
+
+```typescript
+import express, { Request, Response, NextFunction } from 'express';
+import cors from 'cors';
+import helmet from 'helmet';
+import rateLimit from 'express-rate-limit';
+import { QREngine, QROptions } from './services/qrEngine.js';
+
+const app = express();
+
+// Security Middlewares
+app.use(helmet());
+app.use(cors());
+app.use(express.json({ limit: '1mb' }));
+
+// Rate Limiter: Prevent API abuse (max 100 requests per minute per IP)
+const apiLimiter = rateLimit({
+  windowMs: 1 * 60 * 1000,
+  max: 100,
+  message: { error: 'Too many QR generation requests. Please try again later.' }
+});
+
+app.use('/api/', apiLimiter);
+
+/**
+ * GET /api/v1/qr
+ * Query Params: text, ecLevel, margin, colorDark, colorLight, format
+ */
+app.get('/api/v1/qr', async (req: Request, res: Response, next: NextFunction) => {
+  try {
+    const text = req.query.text as string;
+    if (!text) {
+      return res.status(400).json({ error: 'Query parameter "text" is required to create qr code from link.' });
+    }
+
+    const format = ((req.query.format as string) || 'svg').toLowerCase();
+    const ecLevel = ((req.query.ecLevel as string) || 'M').toUpperCase() as 'L' | 'M' | 'Q' | 'H';
+    const margin = parseInt(req.query.margin as string, 10) || 4;
+    const colorDark = (req.query.colorDark as string) || '#000000';
+    const colorLight = (req.query.colorLight as string) || '#FFFFFF';
+
+    const options: QROptions = {
+      text,
+      errorCorrectionLevel: ecLevel,
+      margin,
+      colorDark,
+      colorLight
+    };
+
+    if (format === 'png') {
+      const width = parseInt(req.query.width as string, 10) || 600;
+      const pngBuffer = await QREngine.generatePNGBuffer({ ...options, width });
+      res.setHeader('Content-Type', 'image/png');
+      res.setHeader('Cache-Control', 'public, max-age=86400'); // Cache for 24 hours
+      return res.send(pngBuffer);
+    }
+
+    // Default: Vector SVG
+    const svgString = await QREngine.generateSVG(options);
+    res.setHeader('Content-Type', 'image/svg+xml');
+    res.setHeader('Cache-Control', 'public, max-age=86400');
+    return res.send(svgString);
+
+  } catch (error) {
+    next(error);
+  }
+});
+
+/**
+ * POST /api/v1/qr/batch
+ * JSON Body: { items: Array<QROptions> }
+ */
+app.post('/api/v1/qr/batch', async (req: Request, res: Response, next: NextFunction) => {
+  try {
+    const { items } = req.body;
+    if (!Array.isArray(items) || items.length === 0) {
+      return res.status(400).json({ error: 'JSON payload must contain an array "items" with at least one element.' });
+    }
+
+    if (items.length > 50) {
+      return res.status(400).json({ error: 'Batch limit exceeded. Maximum 50 QR codes allowed per request.' });
+    }
+
+    const results = await Promise.all(
+      items.map(async (item: QROptions) => {
+        const svg = await QREngine.generateSVG({
+          text: item.text,
+          errorCorrectionLevel: item.errorCorrectionLevel || 'M',
+          colorDark: item.colorDark || '#000000',
+          colorLight: item.colorLight || '#FFFFFF'
+        });
+        return { text: item.text, svg };
+      })
+    );
+
+    return res.json({ count: results.length, data: results });
+  } catch (error) {
+    next(error);
+  }
+});
+
+// Central Error Handler
+app.use((err: Error, req: Request, res: Response, _next: NextFunction) => {
+  console.error('[QR-API Error]:', err.message);
+  res.status(500).json({ error: 'Internal Server Error', message: err.message });
+});
+
+const PORT = process.env.PORT || 3000;
+app.listen(PORT, () => {
+  console.log(`🚀 Custom QR Code Generator API running on http://localhost:${PORT}`);
+});
+```
+
+---
+
+## 4. Testing Your API with cURL & Examples
+
+Start the development server:
+
+```bash
+npx ts-node-dev src/app.ts
+```
+
+### Example 1: Requesting a Vector SVG QR Code
+Run the following cURL command to fetch an SVG QR code from a link:
+
+```bash
+curl -X GET "http://localhost:3000/api/v1/qr?text=https://www.qrmaster.net&ecLevel=H&colorDark=%231E293B&colorLight=%23F8FAFC" \
+  -H "Accept: image/svg+xml" \
+  --output qrcode.svg
+```
+
+### Example 2: Requesting a High-Resolution PNG for Print
+Fetch a 1000px high-density PNG QR code:
+
+```bash
+curl -X GET "http://localhost:3000/api/v1/qr?text=https://www.qrmaster.net&format=png&width=1000&ecLevel=Q" \
+  --output qrcode.png
+```
+
+### Example 3: Batch API Request
+Send a POST request with multiple items:
+
+```bash
+curl -X POST "http://localhost:3000/api/v1/qr/batch" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "items": [
+      { "text": "https://www.qrmaster.net/docs", "colorDark": "#0284C7" },
+      { "text": "https://www.qrmaster.net/pricing", "colorDark": "#059669" }
+    ]
+  }'
+```
+
+---
+
+## 5. Production Best Practices & Design Pitfalls
+
+When deploying a production-grade **custom qr code generator free** service, keep these crucial guidelines in mind:
+
+### 1. Maintain Contrast Ratios
+Camera sensors require a minimum contrast ratio between foreground modules and background spaces. Always ensure:
+- Dark modules on light backgrounds (avoid light gray on white or dark blue on black).
+- Inverted QR codes (white modules on black background) work on iOS camera apps, but fail on legacy Android devices and embedded barcode readers. Stick to dark foregrounds on light backgrounds whenever possible.
+
+### 2. Respect Quiet Zone Margins
+The **Quiet Zone** is the empty border surrounding all 4 sides of the QR matrix. The ISO/IEC 18004 specification requires a quiet zone of **at least 4 modules wide**. Reducing or cropping this margin causes camera auto-focus algorithms to miss the finder pattern boundaries.
+
+### 3. Keep Payload Size Minimal
+The more characters you encode into a static QR code, the larger the matrix version becomes (e.g., Version 1 is 21x21 modules; Version 10 is 57x57 modules). High-density matrices require users to stand closer and hold their camera still.
+- **Pro Tip:** Use URL shorteners or dynamic redirection URLs (e.g., `https://qr.domain.com/x9z`) to keep the payload under 30 characters, resulting in a clean, low-density Version 2 matrix that scans instantly.
+
+---
+
+## Conclusion
+
+Creating your own **custom qr code generator** API gives you full programmatic freedom over format, styling, error correction, and batch automation. By leveraging Node.js and vector SVG rendering, your application can effortlessly scale to handle thousands of print-ready requests per second.

+
+# Designing a Low-Latency Dynamic QR Redirect Engine at the Edge with Redis & Middleware
+
+Static QR codes hardcode their destination URL directly into the matrix data. Once printed on 10,000 billboards or product packages, a typo in the URL means reprinting everything at massive cost.
+
+A **dynamic qr code generator** solves this by encoding a permanent short proxy URL (e.g., `https://qr.domain.com/r/xyz123`). An **editable qr code generator** lets you change the target destination link in your dashboard anytime post-print. When scanned, an **editable qr code** intercepts the request, logs scan metrics (device type, geo-location, timestamp), and issues an HTTP `302 Found` or `307 Temporary Redirect` response to the target URL.
+
+However, if your redirect engine takes 800ms to resolve a database query before forwarding the user, the physical scan experience feels sluggish. In this article, we will design a **free dynamic qr code generator** backend engine operating with sub-20ms global redirect latencies using Edge Middleware (Vercel Edge / Cloudflare Workers), Redis in-memory caching, and a **qr code generator with tracking** pipeline.
+
+---
+
+## 1. System Architecture Overview
+
+To achieve sub-20ms global redirect latencies in a **dynamic qr code generator**, database calls must never block the HTTP response thread.

+                  └─────────────────────┘
+```
+
+### Key Architectural Decisions:
+1. **Edge Execution**: Run redirect logic in multi-region PoPs (Points of Presence) close to the physical device.
+2. **Read Path (Hot Path)**: Fetch URL mappings from a distributed, low-latency Redis cache for your **editable qr code generator**.
+3. **Write Path (Analytics Async)**: Push scan metadata to a queue or log collector off the main execution thread so **qr code tracking** adds **0ms** to user delay.
+4. **HTTP Status Code**: Use `307 Temporary Redirect` (or `302 Found`). Never use `301 Moved Permanently`, as browsers will cache the redirect locally and bypass your server on future scans, ruining **qr code generator with tracking** metrics!
+
+---
+
+## 2. Setting Up Edge Middleware in Next.js
+
+Below is an implementation of Edge Middleware in Next.js (`src/middleware.ts` or Cloudflare Worker script) that handles dynamic redirection for an **editable qr code generator**.
+
+### Step 2.1: Installing Dependencies
+
+```bash
+npm install @upstash/redis @upstash/qstash
+```
+
+### Step 2.2: Implementing Edge Redirect Middleware
+
+Create or update `middleware.ts`:
+
+```typescript
+import { NextResponse } from 'next/server';
+import type { NextRequest } from 'next/server';
+import { Redis } from '@upstash/redis';
+
+// Initialize low-latency edge Redis client
+const redis = new Redis({
+  url: process.env.UPSTASH_REDIS_REST_URL!,
+  token: process.env.UPSTASH_REDIS_REST_TOKEN!,
+});
+
+export async function middleware(req: NextRequest) {
+  const { pathname } = req.nextUrl;
+
+  // Match route pattern: /r/:code (e.g., /r/campaign-2026)
+  if (pathname.startsWith('/r/')) {
+    const code = pathname.split('/r/')[1];
+    if (!code) {
+      return NextResponse.redirect(new URL('/404', req.url));
+    }
+
+    const startTime = performance.now();
+
+    // 1. Fetch destination URL from Redis cache (Hot Path)
+    const targetUrl = await redis.get<string>(`qr:link:${code}`);
+
+    if (!targetUrl) {
+      // Fallback: If not in cache, redirect to fallback page or 404
+      return NextResponse.redirect(new URL('/link-expired', req.url));
+    }
+
+    // 2. Extract Device & Geo Metadata from Edge Request Headers for QR Code Tracking
+    const ip = req.headers.get('x-forwarded-for') || req.headers.get('x-real-ip') || '127.0.0.1';
+    const userAgent = req.headers.get('user-agent') || 'Unknown';
+    const country = req.headers.get('x-vercel-ip-country') || req.headers.get('cf-ipcountry') || 'US';
+    const city = req.headers.get('x-vercel-ip-city') || 'Unknown';
+
+    // 3. Asynchronously Log Scan Analytics (Fire and Forget)
+    const scanEvent = {
+      code,
+      targetUrl,
+      timestamp: new Date().toISOString(),
+      ip,
+      userAgent,
+      country,
+      city,
+      latencyMs: Math.round(performance.now() - startTime),
+    };
+
+    // Queue analytic event asynchronously without awaiting
+    const logPromise = redis.lpush('queue:scan_analytics', JSON.stringify(scanEvent));
+
+    if (typeof (req as any).waitUntil === 'function') {
+      (req as any).waitUntil(logPromise);
+    }
+
+    // 4. Return HTTP 307 Temporary Redirect immediately
+    return NextResponse.redirect(targetUrl, {
+      status: 307,
+      headers: {
+        'Cache-Control': 'no-store, no-cache, must-revalidate, proxy-revalidate',
+        'X-Redirect-Latency': `${Math.round(performance.now() - startTime)}ms`,
+      },
+    });
+  }
+
+  return NextResponse.next();
+}
+
+export const config = {
+  matcher: '/r/:path*',
+};
+```
+
+---
+
+## 3. Asynchronous Analytics Processing Pipeline for Tracking
+
+Logging scan events directly to a relational database (like PostgreSQL or MySQL) inside the request loop introduces locking overhead and database connection pool exhaustion under high traffic spikes.
+
+A robust **qr code generator with tracking** streams events into a queue and processes them with a background consumer job.
+
+### Background Consumer Worker (`scripts/analyticsWorker.ts`)
+
+```typescript
+import { Redis } from '@upstash/redis';
+import { PrismaClient } from '@prisma/client';
+
+const redis = new Redis({
+  url: process.env.UPSTASH_REDIS_REST_URL!,
+  token: process.env.UPSTASH_REDIS_REST_TOKEN!,
+});
+
+const prisma = new PrismaClient();
+
+interface ScanEvent {
+  code: string;
+  targetUrl: string;
+  timestamp: string;
+  ip: string;
+  userAgent: string;
+  country: string;
+  city: string;
+  latencyMs: number;
+}
+
+async function startWorker() {
+  console.log('🔄 QR Code Tracking Worker active. Polling scan queue...');
+
+  while (true) {
+    try {
+      // Pop up to 100 scan events in batch from Redis list
+      const rawEvents = await redis.rpop('queue:scan_analytics', 100);
+
+      if (rawEvents && rawEvents.length > 0) {
+        const events: ScanEvent[] = rawEvents.map((item) => JSON.parse(item));
+
+        // Batch insert into database
+        await prisma.scanLog.createMany({
+          data: events.map((e) => ({
+            qrCode: e.code,
+            destination: e.targetUrl,
+            scannedAt: new Date(e.timestamp),
+            ipAddress: e.ip,
+            deviceUserAgent: e.userAgent,
+            countryCode: e.country,
+            cityName: e.city,
+            processingLatency: e.latencyMs,
+          })),
+        });
+
+        console.log(`✅ Processed ${events.length} scan records.`);
+      } else {
+        await new Promise((resolve) => setTimeout(resolve, 1000));
+      }
+    } catch (err) {
+      console.error('❌ Analytics Worker Error:', err);
+      await new Promise((resolve) => setTimeout(resolve, 2000));
+    }
+  }
+}
+
+startWorker();
+```
+
+---
+
+## 4. Handling High-Traffic Campaign Spikes
+
+When a printed **editable qr code** appears on live television or a viral promotional banner, traffic can surge from 10 scans/sec to 20,000 scans/sec instantly.
+
+### Key Resilience Strategies:
+
+1. **Pre-Warming the Edge Cache**: When a user updates a dynamic destination URL in their **editable qr code generator** dashboard, publish the update to Redis immediately:
+   ```typescript
+   await redis.set(`qr:link:${code}`, newTargetUrl);
+   ```
+2. **Stale-While-Revalidate Fallback**: If Redis experiences an outage, fallback to an edge-cached static mapping file or memory LRU cache.
+3. **Bot & Crawler Filtering**: Search engine spiders (Googlebot, Bingbot) and messaging app link prefetchers (WhatsApp, iMessage, Twitter previews) generate fake scans. Filter them out using User-Agent detection before counting unique scans:
+   ```typescript
+   const isBot = /bot|google|baidu|bing|msn|duckduckbot|teoma|slurp|twitterbot|facebookexternalhit|whatsapp/i.test(userAgent);
+   if (isBot) {
+     // Tag or ignore bot scans in qr code tracking
+   }
+   ```

+# Geo-Location URIs vs Deep Links: RFC 5870 geo: Protocol, Apple Maps & Google Maps Traps
+
+Scanning a **qr code for location** to navigate to a physical address—such as a store entrance, real estate open house, event parking lot, or tourist landmark—is a foundational real-world mobile use case.
+
+However, developers building a **location qr code generator** often stumble into a major cross-platform fragmentation trap:
+
+- If you use the official IETF standard `geo:` URI protocol (`geo:37.7749,-122.4194`), Android devices open Google Maps seamlessly, but **iOS camera apps display an error or treat it as an unhandled text string**!
+- If you use a Google Maps web URL (`https://maps.google.com/?q=...`), iOS devices open a browser web page instead of launching the native Apple Maps app.
+
+In this technical guide, we will analyze RFC 5870 geo-location standards, cross-platform mobile OS behavior, client-side W3C Geolocation API fallbacks, and build a smart TypeScript Universal Location Resolver to **print a qr code** for navigation.
+
+---
+
+## 1. Breakdown of Location Format Options
+
+Let's compare the four primary ways to encode geographic location coordinates into a **location qr code generator**:
+
+```
+┌─────────────────────────────────────┬─────────────────────────────┬─────────────────────────────┐
+│ Format Method                       │ iOS Camera App Behavior     │ Android Google Lens Behavior│
+├─────────────────────────────────────┼─────────────────────────────┼─────────────────────────────┤
+│ 1. Standard RFC 5870 (geo:lat,lng)  │ ❌ Fails / Shows plain text │ ✅ Opens Native Maps App    │
+│ 2. Google Maps Web URL              │ ⚠️ Opens Safari Web Browser  │ ✅ Opens Native Google Maps │
+│ 3. Apple Maps Universal Link        │ ✅ Opens Native Apple Maps  │ ⚠️ Opens Web Browser        │
+│ 4. Universal Smart Redirect Link    │ ✅ Opens Native Maps App    │ ✅ Opens Native Maps App    │
+└─────────────────────────────────────┴─────────────────────────────┴─────────────────────────────┘
+```
+
+---
+
+## 2. Understanding the RFC 5870 `geo:` URI Specification
+
+The IETF RFC 5870 specification defines the uniform resource identifier (URI) scheme for geographic locations:
+
+```text
+geo:latitude,longitude,altitude;crs=wgs84;u=uncertainty
+```
+
+### Example RFC 5870 Strings:
+
+```text
+# Basic Latitude & Longitude (San Francisco)
+geo:37.7749,-122.4194
+
+# Latitude, Longitude, and Altitude in meters (100m above sea level)
+geo:48.8584,2.2945,100
+
+# Geo-location with query search string ("Coffee")
+geo:37.7749,-122.4194?q=Coffee
+```
+
+### Why iOS Fails to Parse RFC 5870:
+Apple's iOS Camera App parser does not register `geo:` as a supported URI scheme in its native scanner handler. When an iPhone camera detects `geo:37.7749,-122.4194`, it treats the barcode as raw unformatted text rather than an actionable navigation trigger.
+
+---
+
+## 3. Universal Web Links for Maximum Cross-Platform Compatibility
+
+To ensure a **qr code for location** opens natively on both iPhone and Android devices without errors, developers use **Universal Maps Links**.
+
+### Google Maps Universal Link Syntax:
+```text
+https://www.google.com/maps/search/?api=1&query=37.7749,-122.4194
+```
+
+### Apple Maps Universal Link Syntax:
+```text
+https://maps.apple.com/?ll=37.7749,-122.4194&q=Location+Name
+```
+
+### Cross-Platform Dual-Routing Strategy
+When both iOS and Android users scan a single **print qr code**, the best architectural approach is pointing the QR code to a lightweight serverless edge function that inspects the client `User-Agent` and issues an instant 307 redirect to the respective native map handler:
+
+- If `User-Agent` contains `iPhone`, `iPad`, or `Macintosh` $\to$ Redirect to `https://maps.apple.com/?ll=...`
+- Otherwise (Android / Windows / Linux) $\to$ Redirect to `https://www.google.com/maps/search/?api=1&query=...`
+
+---
+
+## 4. Building a Smart Location Resolver in TypeScript
+
+Below is a complete implementation of a Universal Location Resolver Edge Handler in Next.js / TypeScript for a **location qr code generator**.
+
+### `src/app/api/location-resolver/route.ts`
+
+```typescript
+import { NextRequest, NextResponse } from 'next/server';
+
+export interface LocationQuery {
+  lat: number;
+  lng: number;
+  label?: string;
+}
+
+export function GET(req: NextRequest) {
+  const { searchParams } = new URL(req.url);
+  const latStr = searchParams.get('lat');
+  const lngStr = searchParams.get('lng');
+  const label = searchParams.get('label') || 'Target Location';
+
+  if (!latStr || !lngStr) {
+    return NextResponse.json(
+      { error: 'Query parameters "lat" and "lng" are required.' },
+      { status: 400 }
+    );
+  }
+
+  const lat = parseFloat(latStr);
+  const lng = parseFloat(lngStr);
+
+  if (isNaN(lat) || isNaN(lng)) {
+    return NextResponse.json(
+      { error: 'Coordinates lat and lng must be valid floating point numbers.' },
+      { status: 400 }
+    );
+  }
+
+  // Validate Coordinate Boundaries
+  if (lat < -90 || lat > 90 || lng < -180 || lng > 180) {
+    return NextResponse.json(
+      { error: 'Latitude must be between -90 and 90, Longitude between -180 and 180.' },
+      { status: 400 }
+    );
+  }
+
+  const userAgent = req.headers.get('user-agent') || '';
+  const isAppleDevice = /iPhone|iPad|iPod|Macintosh/i.test(userAgent);
+
+  let targetMapUrl: string;
+
+  if (isAppleDevice) {
+    // Construct Native Apple Maps Deep Link
+    const encodedLabel = encodeURIComponent(label);
+    targetMapUrl = `https://maps.apple.com/?ll=${lat},${lng}&q=${encodedLabel}`;
+  } else {
+    // Construct Universal Google Maps Deep Link
+    const encodedQuery = encodeURIComponent(`${lat},${lng}`);
+    targetMapUrl = `https://www.google.com/maps/search/?api=1&query=${encodedQuery}`;
+  }
+
+  // Return 307 Temporary Redirect
+  return NextResponse.redirect(targetMapUrl, {
+    status: 307,
+    headers: {
+      'Cache-Control': 'no-store, max-age=0',
+    },
+  });
+}
+```
+
+---
+
+## 5. Client-Side Geolocation API Integration & Fallback HTML
+
+If you want to offer a web landing page that shows dynamic distance ("You are 450 meters away from the venue entrance"), you can integrate the browser W3C Geolocation API alongside the QR redirect link when you **print a qr code**.
+
+### Example HTML/JS Client Landing Page (`public/location-landing.html`):
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+<head>
+  <meta charset="UTF-8">
+  <title>Venue Navigation - Location QR Code</title>
+  <style>
+    body { font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, sans-serif; text-align: center; padding: 40px 20px; }
+    .card { max-width: 400px; margin: 0 auto; border: 1px solid #E2E8F0; padding: 24px; border-radius: 12px; box-shadow: 0 4px 6px rgba(0,0,0,0.05); }
+    .btn { display: inline-block; background: #0284C7; color: white; padding: 14px 28px; border-radius: 8px; text-decoration: none; font-weight: 600; margin-top: 16px; }
+  </style>
+</head>
+<body>
+  <div class="card">
+    <h2>📍 Target Destination</h2>
+    <p id="status">Calculating distance to target...</p>
+    <a id="nav-btn" class="btn" href="#">Open Navigation App</a>
+  </div>
+
+  <script>
+    const targetLat = 37.7749;
+    const targetLng = -122.4194;
+
+    const isApple = /iPhone|iPad|iPod|Macintosh/i.test(navigator.userAgent);
+    const navBtn = document.getElementById('nav-btn');
+    const statusEl = document.getElementById('status');
+
+    const mapsUrl = isApple 
+      ? `https://maps.apple.com/?ll=${targetLat},${targetLng}&q=Target+Venue`
+      : `https://www.google.com/maps/search/?api=1&query=${targetLat},${targetLng}`;
+
+    navBtn.href = mapsUrl;
+
+    if ("geolocation" in navigator) {
+      navigator.geolocation.getCurrentPosition(position => {
+        const userLat = position.coords.latitude;
+        const userLng = position.coords.longitude;
+        const distKm = getHaversineDistance(userLat, userLng, targetLat, targetLng);
+        statusEl.innerText = `You are currently ${(distKm * 1000).toFixed(0)} meters away.`;
+      }, () => {
+        statusEl.innerText = "Tap below to open your device maps app.";
+      });
+    }
+
+    function getHaversineDistance(lat1, lon1, lat2, lon2) {
+      const R = 6371;
+      const dLat = (lat2 - lat1) * Math.PI / 180;
+      const dLon = (lon2 - lon1) * Math.PI / 180;
+      const a = Math.sin(dLat/2) * Math.sin(dLat/2) +
+                Math.cos(lat1 * Math.PI / 180) * Math.cos(lat2 * Math.PI / 180) *
+                Math.sin(dLon/2) * Math.sin(dLon/2);
+      const c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
+      return R * c;
+    }
+  </script>
+</body>
+</html>
+```
+
+---
+
+## 6. Summary & Best Practice Rules for Developers
+
+```
+[ ] DO NOT use raw `geo:lat,lng` RFC 5870 strings if your audience includes iOS users.
+[ ] ALWAYS use HTTPS universal web links when creating a qr code for location.
+[ ] Include a human-readable label in the query string (`&q=Store+Name`) so maps apps display a pin marker with your brand name.
+[ ] Validate latitude limits (-90.0 to +90.0) and longitude limits (-180.0 to +180.0) before encoding.
+```
+
+---
+
+## Conclusion
+
+Navigating cross-platform mobile URI quirks is essential for building real-world location QR codes. By implementing smart User-Agent routing between Apple Maps and Google Maps universal links in your **location qr code generator**, developers deliver a flawless 1-tap navigation experience on any smartphone.

+# Automating Mobile QR Code Previews in CI/CD Pipelines with GitHub Actions
+
+When reviewing Pull Requests (PRs) for mobile-first web applications, responsive websites, or PWA features, developers and QA engineers frequently waste time manually copying Vercel or Netlify preview URLs, opening messaging apps, sending links to test devices, or re-typing long URLs into mobile browser address bars.
+
+What if every time a developer opened a Pull Request, a **GitHub Action automatically allowed you to create a qr code from a link** pointing directly to that branch's live preview URL and commented it right into the PR thread?
+
+Quality Assurance testers could simply point their mobile phone camera at the computer screen and instantly test the live staging build!
+
+In this DevOps workflow guide, we will build a custom GitHub Actions workflow (`.github/workflows/qr-preview.yml`) that auto-generates QR preview images when you **create a qr code with a link**.
+
+---
+
+## 1. CI/CD Preview Architecture
+
+Here is how the automated PR feedback loop operates:
+
+```
+┌────────────────────────────────────────┐
+│ Developer Pushes Code to GitHub PR     │
+└───────────────────┬────────────────────┘
+                    │
+                    ▼
+┌────────────────────────────────────────┐
+│ Vercel / Netlify Deploy Preview Builds │ (Generates e.g. https://preview-xyz.vercel.app)
+└───────────────────┬────────────────────┘
+                    │
+                    ▼
+┌────────────────────────────────────────┐
+│ GitHub Action Triggered (pull_request) │
+└───────────────────┬────────────────────┘
+                    │
+                    ▼
+┌────────────────────────────────────────┐
+│ Node.js Script Generates QR Code SVG   │ (Create QR Code From Link)
+└───────────────────┬────────────────────┘
+                    │
+                    ▼
+┌────────────────────────────────────────┐
+│ Action Posts/Updates PR Markdown Comm. │
+└────────────────────────────────────────┘
+```
+
+---
+
+## 2. Setting Up the GitHub Action Workflow
+
+Create a new file in your repository at `.github/workflows/qr-preview.yml`.
+
+### Workflow Configuration (`.github/workflows/qr-preview.yml`)

+            *Automated by QR CI/CD Pipeline*`;
+
+            const comments = await github.rest.issues.listComments({
+              owner: context.repo.owner,
+              repo: context.repo.repo,
+              issue_number: prNumber,
+            });
+
+            const botComment = comments.data.find(comment => 
+              comment.user.type === 'Bot' && comment.body.includes('Mobile Preview QR Code')
+            );
+
+            if (botComment) {
+              await github.rest.issues.updateComment({
+                owner: context.repo.owner,
+                repo: context.repo.repo,
+                comment_id: botComment.id,
+                body: commentBody
+              });
+              console.log('Updated existing PR comment.');
+            } else {
+              await github.rest.issues.createComment({
+                owner: context.repo.owner,
+                repo: context.repo.repo,
+                issue_number: prNumber,
+                body: commentBody
+              });
+              console.log('Created new PR comment.');
+            }
+```
+
+---
+
+## 3. How It Works Under the Hood
+
+### Base64 Data URI Trick for Markdown Rendering
+GitHub Markdown does not allow uploading local SVG files directly from a runner disk into a comment thread without hosted storage.
+
+By encoding the generated vector SVG into a **Base64 Data URI string** (`data:image/svg+xml;base64,PHN2Zy...`), the image renders natively inside GitHub PR comment threads without requiring any external S3 bucket uploads when you **generate a qr code for a link**!
+
+```html
+<img src="data:image/svg+xml;base64,PHN2ZyB4bWxucz0..." width="220" height="220" />
+```
+
+### Preventing Comment Spam
+The script lists existing PR comments and searches for a previous bot message containing `"Mobile Preview QR Code"`. If a developer pushes 5 new commits to the PR, the action **updates the single existing comment** with the latest deployment link instead of posting 5 separate duplicate comments.
+
+---
+
+## 4. Advanced Integrations: Netlify & Cloudflare Pages Pipelines
+
+If your repository deploys via Netlify or Cloudflare Pages instead of Vercel, you can hook into their deployment completion events.
+
+### Netlify Deployment Hook Example:
+
+```yaml
+      - name: Fetch Netlify Preview Link
+        id: netlify
+        uses: nwtgck/actions-netlify@v3.0
+        with:
+          publish-dir: './build'
+          github-token: ${{ secrets.GITHUB_TOKEN }}
+          deploy-alias: pr-${{ github.event.number }}
+        env:
+          NETLIFY_AUTH_TOKEN: ${{ secrets.NETLIFY_AUTH_TOKEN }}
+          NETLIFY_SITE_ID: ${{ secrets.NETLIFY_SITE_ID }}
+```
+
+### Adding Device UTM Tracking Parameters
+To measure how many QA test scans originate from GitHub Pull Request comments vs Slack links, append custom UTM parameters to **make a qr code for a link** before generating the barcode:
+
+```javascript
+const previewUrlWithUtm = `${previewUrl}?utm_source=github&utm_medium=pr_comment&utm_campaign=qa_mobile_test`;
+```
+
+---
+
+## 5. Automated Unit & E2E Testing with Playwright
+
+To take mobile QA automation a step further, you can combine this workflow with headless E2E testing tools like Microsoft Playwright or Cypress.
+
+For instance, your CI runner can launch a mobile Chrome emulation context, load the preview deployment URL encoded in the QR code, take automated screenshots across different screen viewport sizes (iPhone 15 Pro, Pixel 8, iPad Air), and upload visual diffs directly into the Pull Request build artifact summary.
+
+```typescript
+import { test, expect, devices } from '@playwright/test';
+
+test.use({ ...devices['iPhone 15 Pro'] });
+
+test('Mobile Staging Visual Regression Check', async ({ page }) => {
+  await page.goto(process.env.STAGING_URL || 'http://localhost:3000');
+  await expect(page).toHaveTitle(/QR Master/);
+  await page.screenshot({ path: 'mobile-preview.png' });
+});
+```
+
+---
+
+## 6. Security & Rate Limiting Guidelines
+
+```
+[ ] Grant `pull-requests: write` permission scoped strictly to the workflow job.
+[ ] Store third-party tokens (Vercel/Netlify tokens) securely in GitHub Repository Secrets (`${{ secrets.VERCEL_TOKEN }}`).
+[ ] Enforce Base64 length checks to ensure generated SVG payload remains under 64 KB to comply with GitHub comment payload size limits.
+```
+
+---
+
+## Conclusion
+
+Automating mobile QR code previews in your CI/CD pipeline to **create a qr code from a link** eliminates friction for QA teams, product managers, and developers testing mobile-first web features.

+Generating a single QR code manually in a web browser takes seconds. But when an enterprise client hands you a CSV file containing **50,000 product SKU inventory codes**, **10,000 attendee event tickets**, or **5,000 personalized employee ID badge links**, manual generation becomes impossible.
+
+Browser-based tools will freeze or crash browser tabs when processing tens of thousands of records. You need a dedicated **bulk qr code generator** CLI tool that leverages multi-core CPU workers, streams large files without memory exhaustion, and packages vector SVG outputs into a clean ZIP archive.
+
+In this guide, we will build a production-grade **bulk qr code generator from excel** and CSV files in both **Node.js** and **Python** capable of batch processing thousands of QR codes per minute.
+
+---
+
+## 1. System Requirements & Architecture
+
+Building a **free bulk qr code generator** CLI tool capable of processing massive dataset imports requires avoiding loading entire multi-gigabyte CSV files into RAM memory all at once.
+
+```
+┌─────────────────────────┐
+│ Input CSV / Excel File  │ (e.g. 50,000 rows: ID, Payload, Label)
+└────────────┬────────────┘
+             │
+             ▼
+┌─────────────────────────┐
+│ Stream Reader / Parser  │ (Node.js csv-parser / Python csv module)
+└────────────┬────────────┘
+             │
+             ▼
+┌─────────────────────────┐
+│ Worker Pool Queue       │ (Parallel processing across CPU cores)
+└────────────┬────────────┘
+             │
+             ▼
+┌─────────────────────────┐
+│ Vector SVG / PNG Export │ (Output folder: ./output/QR_00001.svg)
+└─────────────────────────┘
+```
+
+---
+
+## 2. Implementation 1: Node.js / TypeScript CLI Tool
+
+We will build a **csv qr code generator** in Node.js using `commander` for CLI flags, `csv-parser` for streaming, and `p-limit` to bound CPU concurrency.
+
+### Step 2.1: Dependencies
+
+```bash
+npm install commander csv-parser qrcode p-limit archiver
+npm install --save-dev typescript @types/node @types/csv-parser @types/archiver ts-node
+```
+
+### Step 2.2: Node.js CLI Code (`src/bulkQrCli.ts`)
+
+```typescript
+import fs from 'fs';
+import path from 'path';
+import { Command } from 'commander';
+import csvParser from 'csv-parser';
+import QRCode from 'qrcode';
+import pLimit from 'p-limit';
+
+interface CsvRow {
+  filename: string;
+  payload: string;
+}
+
+const program = new Command();
+
+program
+  .name('batch-qr')
+  .description('High-speed offline bulk qr code generator CLI')
+  .version('1.0.0')
+  .requiredOption('-i, --input <path>', 'Input CSV file path (columns: filename, payload)')
+  .option('-o, --output <path>', 'Output directory path', './output_qr')

+    fs.createReadStream(inputPath)
+      .pipe(csvParser())
+      .on('data', (data) => {
+        if (data.payload) {
+          rows.push({
+            filename: data.filename || `qr_${rows.length + 1}`,
+            payload: data.payload,
+          });
+        }
+      })
+      .on('end', () => resolve())
+      .on('error', (err) => reject(err));
+  });
+
+  console.log(`📊 Found ${rows.length} records for bulk qr generation.`);
+
+  const startTime = Date.now();
+  const limit = pLimit(concurrency);
+  let completed = 0;
+
+  // 2. Parallel Generation Queue
+  const tasks = rows.map((row) =>
+    limit(async () => {
+      const sanitizedFilename = row.filename.replace(/[^a-z0-9_-]/gi, '_');
+      const filePath = path.join(outputDir, `${sanitizedFilename}.${format}`);
+
+      try {

+            type: 'svg',
+            errorCorrectionLevel: ecLevel,
+            margin: 4,
+          });
+          fs.writeFileSync(filePath, svgString, 'utf8');
+        }
+
+        completed++;
+        if (completed % 500 === 0 || completed === rows.length) {
+          console.log(`✅ Progress: ${completed} / ${rows.length} generated...`);
+        }
+      } catch (err) {
+        console.error(`❌ Error generating ${row.filename}:`, (err as Error).message);
+      }
+    })
+  );
+
+  await Promise.all(tasks);
+
+  const durationSec = ((Date.now() - startTime) / 1000).toFixed(2);

+}
+
+runBatch().catch((err) => {
+  console.error('Fatal Batch Error:', err);
+  process.exit(1);
+});
+```
+

+
+## 3. Implementation 2: Python Multi-Processing CLI
+
+Python offers native `multiprocessing` for parallel execution across all available CPU threads in a **bulk qr code generator from excel**.
+
+### Step 3.1: Install Dependencies
+
+```bash
+pip install qrcode[pil] click pandas openpyxl
+```
+
+### Step 3.2: Python CLI Script (`batch_qr.py`)
+
+```python
+import os
+import time
+import pandas as pd
+import qrcode
+from qrcode.image.svg import SvgPathImage
+import click

+
+# PDF & File QR Code Generator: How to Convert Documents, Menus & PDFs into Scannable Barcodes
+
+Converting digital documents, PDF menus, product brochures, user manuals, and event schedules into scannable QR codes is one of the most effective ways to eliminate paper waste and distribute digital collateral in physical spaces.
+
+Whether a restaurant guest scans a table sign to view a restaurant menu PDF, a conference attendee scans a badge to download a presentation slide deck, or an industrial customer scans packaging to view a PDF safety manual, using a **pdf qr code generator free** tool connects paper touchpoints directly to digital cloud files.
+
+However, developers and marketers often face technical challenges:
+- How do you host PDF files so they load instantly on mobile networks?
+- Should you use a static file link or an editable **file qr code generator**?
+- How do you optimize PDF file size so phone browsers do not freeze when downloading large multi-megabyte documents over cellular connections?
+
+In this guide, we will cover the end-to-end architecture of a **file to qr code generator**, cloud storage hosting (S3/Cloudflare R2), PDF optimization, and building a TypeScript file upload pipeline.
+
+---
+
+## 1. System Architecture: How a PDF QR Code Works
+
+You cannot embed a 5 MB PDF file directly inside the physical black-and-white modules of a 2D QR matrix. A QR code can store a maximum of ~2,953 bytes.
+
+Therefore, a **pdf qr code generator** works by uploading the PDF document to a secure cloud storage bucket (e.g. AWS S3, Cloudflare R2, Google Cloud Storage) and encoding the hosted URL into a QR barcode.
+
+```
+┌─────────────────────────┐
+│ User Uploads PDF File   │ (e.g. menu.pdf, 1.2 MB)
+└────────────┬────────────┘
+             │
+             ▼
+┌─────────────────────────┐
+│ PDF Optimization Engine │ (Compresses images & vectors)
+└────────────┬────────────┘
+             │
+             ▼
+┌─────────────────────────┐
+│ Cloud Object Storage    │ (AWS S3 / Cloudflare R2 CDN)
+└────────────┬────────────┘
+             │
+             ▼
+┌─────────────────────────┐
+│ Dynamic Proxy Short Link│ (e.g. https://qr.domain.com/pdf/menu-2026)
+└────────────┬────────────┘
+             │
+             ▼
+┌─────────────────────────┐
+│ Vector SVG Barcode      │ (Scanned by Mobile Device Camera)
+└─────────────────────────┘
+```
+
+---
+
+## 2. Static vs. Dynamic PDF QR Codes
+
+When building a **file qr code generator**, choosing between static and dynamic architecture is critical:
+
+```
+┌───────────────────────────────────────┬───────────────────────────────────────┐
+│ Static PDF QR Code                    │ Dynamic File QR Code Generator        │
+├───────────────────────────────────────┼───────────────────────────────────────┤
+│ Links directly to S3 URL              │ Links to proxy URL (/pdf/menu)        │
+│ (e.g., s3.aws.com/b/menu-v1.pdf)      │ which redirects to active PDF.        │
+│                                       │                                       │
+│ ❌ File CANNOT be updated after print  │ 🟢 Replace PDF file anytime           │
+│ ❌ No scan analytics tracking          │ 🟢 Full scan metrics (Geo-IP, device) │
+│ ⚠️ Long S3 URLs create dense barcodes  │ 🟢 Short proxy URL creates clean code │
+└───────────────────────────────────────┴───────────────────────────────────────┘
+```
+
+> **Best Practice Rule**: Always use a **dynamic file qr code generator** for PDF documents. If a menu price changes or a brochure is revised, you can upload a new PDF version to your dashboard—the printed QR code on tables or flyers stays active and automatically serves the updated PDF!
+
+---
+
+## 3. PDF Optimization for Mobile Scanning Speed
+
+When mobile users scan a PDF barcode over a 4G/5G connection, an uncompressed 15 MB PDF takes 10+ seconds to load in Safari or Chrome, resulting in high bounce rates.
+
+### Golden Rules for Mobile PDF Optimization:
+1. **Compress Raster Images**: Downsample images inside the PDF to 150 DPI (suitable for mobile screens) instead of 300+ DPI print resolution.
+2. **Subset Embedded Fonts**: Include only the characters used in the document rather than embedding entire font families.
+3. **Linearization (Fast Web View)**: Enable "Fast Web View" when exporting PDFs. This restructures the PDF stream so mobile browsers display Page 1 immediately before the rest of the file finishes downloading!
+4. **Target File Size Limit**: Keep PDF file size **under 2.5 MB** for instant mobile loading.
+
+---
+
+## 4. TypeScript Implementation: Building a Cloud PDF QR Pipeline
+
+Below is a complete implementation in TypeScript that handles PDF uploads to S3-compatible storage (Cloudflare R2), generates a short dynamic redirect link, and exports a vector SVG QR code.
+
+### Step 4.1: Installation
+```bash
+npm install @aws-sdk/client-s3 qrcode
+npm install --save-dev typescript @types/node
+```
+
+### Step 4.2: PDF QR Service (`src/services/pdfQrService.ts`)
+
+```typescript
+import { S3Client, PutObjectCommand } from '@aws-sdk/client-s3';
+import QRCode from 'qrcode';
+
+// Initialize S3 / Cloudflare R2 Client
+const s3 = new S3Client({
+  region: 'auto',
+  endpoint: process.env.R2_ENDPOINT!,
+  credentials: {
+    accessKeyId: process.env.R2_ACCESS_KEY_ID!,
+    secretAccessKey: process.env.R2_SECRET_ACCESS_KEY!,
+  },
+});
+
+export interface PdfUploadOptions {
+  fileBuffer: Buffer;
+  originalFileName: string;
+  slug: string;
+}
+
+export class PdfQrService {
+  /**
+   * Uploads a PDF to S3/R2 storage and returns a vector SVG QR code.
+   */
+  public static async createPdfQr(options: PdfUploadOptions): Promise<{ cdnUrl: string; svgQr: string }> {
+    const { fileBuffer, originalFileName, slug } = options;
+
+    const fileKey = `documents/${Date.now()}_${originalFileName.replace(/[^a-z0-9.]/gi, '_')}`;
+
+    // 1. Upload PDF File to Cloud Storage Bucket
+    const uploadCommand = new PutObjectCommand({
+      Bucket: process.env.R2_BUCKET_NAME!,
+      Key: fileKey,
+      Body: fileBuffer,
+      ContentType: 'application/pdf',
+      ContentDisposition: 'inline', // Opens inside browser instead of forcing download
+      CacheControl: 'public, max-age=31536000',
+    });
+
+    await s3.send(uploadCommand);
+
+    const cdnUrl = `${process.env.CDN_BASE_URL}/${fileKey}`;
+
+    // 2. Generate Managed Short Redirect URL for Dynamic Editing
+    const proxyRedirectUrl = `https://www.qrmaster.net/r/doc/${slug}`;
+
+    // 3. Generate High-Quality Vector SVG Barcode
+    const svgQr = await QRCode.toString(proxyRedirectUrl, {
+      type: 'svg',
+      errorCorrectionLevel: 'M',
+      margin: 4,
+      color: { dark: '#0F172A', light: '#FFFFFF' },
+    });
+
+    return { cdnUrl, svgQr };
+  }
+}
+```
+
+---
+
+## 5. Frequently Asked Questions (FAQ)
+
+### Q1: How do I generate a free QR code for a PDF?
+Upload your PDF to a cloud host (such as Google Drive, Dropbox, or your website server), copy the share link, and paste it into a **pdf qr code generator free** tool like QR Master to generate a vector SVG code.
+
+### Q2: Can I change the PDF file after printing the QR code?
+Yes, provided you use a **file to qr code generator** with dynamic proxy links. You can upload a new PDF file to replace the old document in your dashboard without reprinting the physical QR code.
+
+### Q3: Why does my PDF QR code force a download instead of opening in Safari?
+This is controlled by the HTTP `Content-Disposition` header served by your cloud host. If set to `attachment`, the browser forces a download. Set `Content-Disposition: inline` so mobile browsers render the PDF directly on screen!
+
+---
+
+## Conclusion
+
+Using a **pdf qr code generator** allows businesses to replace bulky paper manuals and printed menus with instant digital experiences. By hosting PDFs on fast S3/R2 CDNs, setting `inline` view headers, and using dynamic redirect links, you deliver a seamless mobile document experience.
+

+
+# QR Code Generator That Never Expires: The Truth About Hidden Limits & Permanent Free QR Codes
+
+Few things are more frustrating for a business owner or marketer than printing 500 brochures, packaging labels, or restaurant tabletop signs, only to discover two weeks later that the printed QR code has stopped working because a third-party generator placed the link behind a hidden subscription paywall.
+
+Every day, thousands of users search Google for phrases like:
+- *"qr code generator does not expire"*
+- *"permanent qr code generator"*
+- *"free forever qr code generator"*
+- *"qr code generator no subscription"*
+
+Why does this happen so frequently? Because many commercial QR tools use aggressive **freemium lock-in tactics**: they allow users to generate a "free" code, wait until the physical materials are printed and distributed, and then redirect the barcode to a paywall blocking screen until the user pays a monthly subscription fee.
+
+In this technical guide, we will unpack the computer science reality of how QR code expiration actually works, how to generate 100% permanent static QR codes that physically **cannot expire**, and how to choose a **permanent qr code generator** for your projects.
+
+---
+
+## 1. The Computer Science Reality: Can a QR Code Physically Expire?
+
+To understand expiration, you must understand where the data lives. A QR code is a 2D optical barcode that stores binary data in a physical matrix grid of dark and light modules.
+
+```
+┌───────────────────────────────────────┬───────────────────────────────────────┐
+│ Static QR Code (Permanent)            │ Dynamic Proxy QR Code                 │
+├───────────────────────────────────────┼───────────────────────────────────────┤
+│ Payload (URL, text, WiFi) is encoded │ Encodes a short proxy URL link        │
+│ directly into the matrix bits.        │ (e.g. https://service.com/r/123)     │
+│                                       │                                       │
+│ ❌ CANNOT EXPIRE physically           │ ⚠️ EXPIRES if proxy server is closed  │
+│ ❌ No server or account required       │ ⚠️ Requires active redirect service   │
+└───────────────────────────────────────┴───────────────────────────────────────┘
+```
+
+### Static QR Codes: 100% Expiration-Proof
+A static QR code generated by a **static qr code generator** encodes the raw text or URL directly into the matrix (using ISO/IEC 18004 Reed-Solomon encoding). 
+- Once printed on paper, metal, or plastic, the barcode is purely offline data—like a printed book or a 1D supermarket EAN barcode.
+- **There is no central server, database, or account attached.**
+- As long as the printed paper remains clean and readable, a camera reading a static QR code in 50 years will extract the exact same string. **A static QR code cannot expire.**
+
+### Dynamic Proxy QR Codes: Service-Dependent
+A dynamic QR code encodes a short managed proxy URL (e.g., `https://qr.domain.com/r/xyz123`) instead of the final website link.
+- When scanned, the phone contacts the proxy server, which looks up the target destination in a database and forwards the scanner via an HTTP 307 redirect.
+- If the proxy service goes out of business, deletes your account, or cancels your plan, the short proxy link returns a `404 Not Found` or payment wall.
+
+---
+
+## 2. Deconstructing the "Free QR Code Trap"
+
+Many online QR tools take advantage of user unfamiliarity with the difference between static and dynamic codes.

+- **Direct Target URL** (e.g. `https://yourcompany.com/menu`): It is a **static permanent QR code**. It is 100% safe and will never expire!
+- **Obfuscated Third-Party URL** (e.g. `https://qr-gen-app.link/x79z`): It is a **dynamic proxy code**. If you are on a free trial, it WILL expire when the trial ends unless you pay!

+## 4. Programmatic Implementation: Building a Guaranteed Non-Expiring QR Generator
+
+To ensure your applications generate **permanent qr code generator** outputs programmatically, build an in-house static generator module in TypeScript.
+
+### Step 4.1: Installation
+```bash
+npm install qrcode
+npm install --save-dev typescript @types/node
+```
+
+### Step 4.2: Permanent Static QR Service (`src/services/permanentQrEngine.ts`)
+
+```typescript
+import QRCode from 'qrcode';
+
+export interface StaticQrConfig {
+  text: string;
+  errorCorrection?: 'L' | 'M' | 'Q' | 'H';
+  colorDark?: string;
+  colorLight?: string;
+}
+
+export class PermanentQrEngine {
+  /**
+   * Generates a 100% static, non-expiring vector SVG QR code.
+   * Direct payload encoding ensures zero third-party server dependency.
+   */
+  public static async createPermanentSvg(config: StaticQrConfig): Promise<string> {
+    const {
+      text,
+      errorCorrection = 'M',
+      colorDark = '#000000',
+      colorLight = '#FFFFFF',
+    } = config;
+
+    if (!text || text.trim().length === 0) {
+      throw new Error('Payload text or URL is required to generate a static QR code.');
+    }
+
+    try {
+      const svgString = await QRCode.toString(text, {
+        type: 'svg',
+        errorCorrectionLevel: errorCorrection,
+        margin: 4,
+        color: {
+          dark: colorDark,
+          light: colorLight,
+        },
+      });
+
+      return svgString;
+    } catch (err) {
+      throw new Error(`Static QR Generation Error: ${(err as Error).message}`);
+    }
+  }
+}
+```
+

+
+## 5. Frequently Asked Questions (FAQ)
+
+### Q1: Is there a free unlimited qr code generator that never expires?
+**Yes.** Any **static qr code generator** that encodes your destination URL directly into the matrix creates a permanent barcode that never expires. Static codes require no account or subscription.
+
+### Q2: What happens if the domain of a static QR code changes?
+Because a static code hardcodes the URL into the matrix, if your website domain changes (e.g. from `site.com` to `newsite.com`), the static code will still point to `site.com`. You can fix this by setting up a domain-level 301 redirect on your web server from your old domain to your new domain!
+
+### Q3: How do I get a permanent QR code with a logo?
+Use a **custom qr code generator** enforcing Reed-Solomon **Level H** error correction. This allows you to embed a brand logo in the center while keeping the static matrix 100% permanent.
+
+---
+
+## Conclusion
+
+Understanding the fundamental technical difference between static matrix encoding and dynamic proxy redirects protects you from predatory subscription paywalls. For permanent print campaigns where URLs are stable, a **permanent qr code generator** using static SVG output is the safest, zero-cost choice.

+# Preventing Quishing (QR Phishing): Building an Automated Threat Inspection Pipeline
+
+As QR codes become standard infrastructure for payments, Wi-Fi connections, and physical login flows, **qr code security** has become a top priority. Cybercriminals have adopted **Quishing** (QR Phishing)—the act of replacing physical QR codes on parking meters, posters, or restaurant tables with malicious codes that redirect victims to credential-harvesting phishing portals.
+
+Because security scanners in email gateways and web browsers cannot inspect physical paper stickers, Quishing bypasses traditional perimeter defenses.
+
+For SaaS platforms building a **secure qr code generator** that allows users to create dynamic redirects, preventing malicious actors from turning your platform into a phishing proxy is a major AppSec priority.
+
+In this cybersecurity guide, we will analyze Quishing attack mechanics and build an automated threat inspection pipeline in TypeScript to ensure your platform remains a **safe qr code generator**.
+
+---
+
+## 1. Deconstructing the Quishing Attack Vector
+
+Unlike standard phishing emails containing suspicious links like `http://paypal-security-login.xyz`, Quishing exploits the visual obscurity of 2D barcodes. Humans cannot read a QR matrix with their eyes; they must scan it first to reveal the URL.
+
+```
+┌────────────────────────────────────────┐
+│ Attacker Swaps Physical QR Sticker     │

+                    ▼
+┌────────────────────────────────────────┐
+│ Victim Enters Password / MFA Credentials│
+└───────────────────┴────────────────────┘
+```
+
+### Common Evasion Tactics in QR Code Security:
+1. **Multi-Hop Redirections**: Using 3 or 4 chained shorteners (`bit.ly` $\to$ `tinyurl` $\to$ malicious domain) to obfuscate final destination.
+2. **Time-Gated Payload Switching**: Pointing the QR code to a benign site during initial review, then updating the target to a phishing page after printing.
+3. **Geo-Targeted Cloaking**: Serving a harmless homepage to cloud inspection bots (AWS/GCP IPs), but redirecting mobile device user-agents to phishing kits.
+
+---
+
+## 2. Architecture of a Secure QR Code Generator Pipeline
+
+When a user submits a destination URL in your **secure qr code generator**, it must pass through an automated inspection pipeline prior to link activation:
+
+```

+## 3. Step-by-Step Implementation in TypeScript
+
+Let's build a threat scanner module in TypeScript for a **safe qr code generator**.
+
+### Step 3.1: Install Dependencies
+
+```bash
+npm install axios google-auth-library valid-url tldts

+  }
+}
+```
+

+
+## 4. Best Practices for QR Code Security
+
+Implementing automated URL scanning is only step one. Enforce these operational safeguards across a **secure qr code generator**:
+
+1. **Mandatory Custom Domain Support**: Allow enterprise users to brand dynamic QR links with their own custom domain (e.g., `qr.brand.com`) instead of sharing a generic domain pool. This isolates reputation.
+2. **Real-Time URL Re-Scanning**: Re-run threat scans periodically (e.g., every 24 hours) on active dynamic QR codes to catch time-gated payload switching attacks.
+3. **Phishing Report Abuse Button**: Include a small "Report Abuse" link on interstitial preview pages so users can flag suspicious links immediately.
+
+---
+
+## Conclusion
+
+Quishing poses a real threat to digital-to-physical user trust. By implementing automated URL syntax sanitization, multi-hop redirect tracing, and Google Safe Browsing integration, developers can build a **secure qr code generator** that protects platforms and users from malicious QR phishing attacks.

+
+# Understanding Reed-Solomon Error Correction Math & Safe Logo Embedding in QR Codes
+
+Many developers assume QR codes are fragile grids where changing a single black module into white destroys the entire payload. In reality, QR codes generated by a **custom qr code generator** are engineered with **Reed-Solomon Error Correction**, a powerful algebraic coding scheme that allows up to 30% of the physical barcode to be completely destroyed, stained, or covered by a company logo while remaining 100% scannable.
+
+However, naive logo overlays—such as slapping a large PNG graphic directly into the center of a QR code using image editing software—frequently cause scan failures in low-light or low-resolution camera sensors.
+
+In this article, we will unpack the computer science math behind Galois Fields $GF(2^8)$, Reed-Solomon error correction polynomials, and how a **branded qr code generator** computes safe logo placement margins without corrupting the barcode matrix.
+
+---
+
+## 1. The Computer Science Math of Reed-Solomon Codes
+
+Reed-Solomon error correction in a **custom qr code generator** operates by representing data as polynomial coefficients over a finite field (also known as a **Galois Field**, denoted as $GF(2^8)$).
+
+### Finite Field Arithmetic: $GF(2^8)$
+Computers store data in bytes ($8\text{ bits} = 256$ distinct values). In $GF(2^8)$, arithmetic operations (addition, multiplication) are defined such that results never overflow 8 bits (values stay strictly between $0$ and $255$).
+
+- **Addition & Subtraction**: In $GF(2^8)$, addition is equivalent to bitwise XOR (`^` in JavaScript/C++):
+  $$A + B = A \oplus B$$
+- **Multiplication**: Multiplication uses a generator polynomial (typically $x^8 + x^4 + x^3 + x^2 + 1$, corresponding to the primitive decimal polynomial $285$).
+
+### The Generator Polynomial
+To generate $R$ error correction codewords for a data message polynomial $M(x)$, the message is multiplied by $x^R$ and divided by a generator polynomial $G(x)$:
+
+$$G(x) = \prod_{i=0}^{R-1} (x - \alpha^i)$$
+
+The remainder of this polynomial division forms the **Error Correction Codewords** appended to the end of the QR payload.
+
+When a camera reads a damaged matrix from a **qr code designer**:
+1. It evaluates the polynomial to find **Syndromes** ($S_1, S_2, \dots, S_R$).
+2. If all syndromes equal $0$, the matrix has zero errors.
+3. If syndromes are non-zero, algorithms like **Berlekamp-Massey** or **Chien Search** locate the exact error positions and correct the inverted bit values automatically!
+
+---
+
+## 2. Error Correction Capacity Levels in QR Codes
+
+The ISO/IEC 18004 specification defines four error correction levels in a **custom qr code generator free** engine, determining how many redundant codewords are added to the matrix:
+
+```
+┌─────────────────────────┬──────────────────────┬───────────────────────────────┐
+│ Error Correction Level  │ Recovery Capacity    │ Max Logo Coverage Budget      │
+├─────────────────────────┼──────────────────────┼───────────────────────────────┤
+│ Level L (Low)           │ ~7% of codewords     │ Dangerous (Max < 4% surface)  │
+│ Level M (Medium)        │ ~15% of codewords    │ Low (Max ~8% surface)         │
+│ Level Q (Quartile)      │ ~25% of codewords    │ Moderate (Max ~15% surface)   │
+│ Level H (High)          │ ~30% of codewords    │ High (Max ~22-25% surface)    │
+└─────────────────────────┴──────────────────────┴───────────────────────────────┘
+```
+
+When you place a logo over the center of a QR code using a **custom qr code generator**, you are intentionally destroying codewords. Therefore:
+> **Golden Rule**: Always set Error Correction Level to **Level H (High)** whenever embedding logos or custom artwork.
+
+---
+
+## 3. Mathematical Rules for Safe Logo Embedding
+
+Overlaying a logo is not just about keeping the covered area under 30%. Camera scanners face environmental degradation (glare, shadows, camera blur, dirty lenses). If your logo consumes 28% of the error correction budget, a slight lens smudge will push total error past 30%, causing scan failure!
+
+### Rule 1: Never Touch the Three Finder Patterns
+The three large $7 \times 7$ square finder patterns in the top-left, top-right, and bottom-left corners are sacrosanct. If a camera cannot detect all three finder patterns, it cannot determine orientation or matrix dimensions, and decoding aborts instantly before Reed-Solomon math is even attempted!
+
+### Rule 2: Keep Logo Surface Area Below 20%
+To ensure reliable scanning across all smartphone models and lighting conditions in your **custom qr code designer**, limit your logo footprint to **15% to 20% of the total matrix area**.
+
+$$\text{Max Logo Dimension (px)} = \text{Matrix Width (px)} \times \sqrt{0.20} \approx \text{Matrix Width} \times 0.44$$
+
+### Rule 3: Add a Protective Padding Zone (Quiet Boundary)
+Logos should never merge directly into surrounding QR modules. A 2-module wide solid background padding around the logo prevents module misinterpretation.
+
+---
+
+## 4. Programmatic Implementation: Merging Logo into QR SVG with Node.js
+
+Below is a Node.js TypeScript module that programmatically computes matrix dimensions, generates a Level H QR SVG, embeds a centered vector logo, and applies a protective background mask for a **create custom qr code** service.
+
+### Step 4.1: Code Implementation (`src/services/customQrBuilder.ts`)
+
+```typescript
+import QRCode from 'qrcode';
+
+export interface LogoEmbedOptions {
+  text: string;
+  logoSvgContent: string; // Raw SVG string of logo (e.g. <path .../>)
+  logoWidthPercent?: number; // Target logo width as percentage of matrix (default: 20%)
+  colorDark?: string;
+  colorLight?: string;
+}
+
+export class CustomQRBuilder {
+  /**
+   * Generates a combined SVG string with centered logo and protective padding.
+   */
+  public static async generateLogoQR(options: LogoEmbedOptions): Promise<string> {
+    const {
+      text,
+      logoSvgContent,
+      logoWidthPercent = 20,
+      colorDark = '#090D16',
+      colorLight = '#FFFFFF',
+    } = options;
+
+    // Enforce Level H (30% error tolerance)
+    const qrMatrix = QRCode.create(text, { errorCorrectionLevel: 'H' });
+    const moduleCount = qrMatrix.modules.size; // Total modules per side (e.g., 29x29)
+
+    const size = 500; // SVG canvas size in pixels
+    const margin = 4; // Module padding
+    const totalModules = moduleCount + margin * 2;
+    const moduleSizePx = size / totalModules;
+
+    // Compute Logo Pixel Bounds
+    const maxLogoPercent = Math.min(Math.max(logoWidthPercent, 10), 22);
+    const logoSizePx = size * (maxLogoPercent / 100);
+    const logoOffset = (size - logoSizePx) / 2;
+
+    // Protective padding around logo (in pixels)
+    const paddingPx = moduleSizePx * 1.5;
+    const padSizePx = logoSizePx + paddingPx * 2;
+    const padOffset = (size - padSizePx) / 2;
+
+    // 1. Generate Base QR SVG Paths
+    const rawSvg = await QRCode.toString(text, {
+      type: 'svg',
+      errorCorrectionLevel: 'H',
+      margin,
+      color: { dark: colorDark, light: colorLight },
+    });
+
+    // 2. Extract SVG Inner Content (Paths)
+    const svgInnerMatch = rawSvg.match(/<svg[^>]*>([\s\S]*?)<\/svg>/i);
+    const baseContent = svgInnerMatch ? svgInnerMatch[1] : '';
+
+    // 3. Construct Final Composite SVG with Protective White Rect + Logo
+    const compositeSvg = `
+<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 ${size} ${size}" width="${size}" height="${size}">
+  <!-- Base QR Matrix -->

+    fill="${colorLight}" 
+    rx="${moduleSizePx.toFixed(2)}" 
+  />
+
+  <!-- Embedded Centered Brand Logo -->
+  <g transform="translate(${logoOffset.toFixed(2)}, ${logoOffset.toFixed(2)}) scale(${(logoSizePx / 100).toFixed(4)})">
+    ${logoSvgContent}
+  </g>
+</svg>`.trim();
+
+    return compositeSvg;
+  }
+}
+```
+

+
+## 5. Verification & Scannability Testing Checklist
+
+Before deploying a **custom qr code generator** with embedded logos, run through this automated and manual test matrix:
+
+```
+[ ] Enforce Level H Error Correction in code config.
+[ ] Verify logo consumes ≤ 20% total matrix area.
+[ ] Confirm finder patterns (3 corner squares) are 100% un-obscured.
+[ ] Test scan under low-light conditions (phone screen at 20% brightness).
+[ ] Test scan at 45-degree angled perspective.
+[ ] Test scan using both native iOS Camera App and Android Google Lens.
+```
+
+---
+
+## Conclusion
+
+Reed-Solomon error correction is an engineering marvel that makes a **custom qr code generator** with logo embedding possible. By understanding finite field mathematics, enforcing Level H error recovery, and restricting logo surface area to 20%, developers can build stunning, branded QR codes without sacrificing scan reliability.

+# Parsing vCard (RFC 2426/6350) Specifications & Optimizing 2D Barcode Payload Limits
+
+Digital business cards powered by a **vcard qr code generator** allow users to instantly save contact details—name, phone number, email, website, job title, and social links—directly into an iOS or Android address book with a single camera scan.
+
+Behind the scenes, building a **qr code generator for business cards** relies on the **vCard specification** (RFC 2426 for vCard 3.0 and RFC 6350 for vCard 4.0).
+
+However, many developers run into a major issue: when users paste extensive bio notes, social media links, profile photos, or secondary addresses into a **free qr code generator for business cards**, the QR matrix becomes extremely dense (Version 25+ with over 1,500 modules). This results in a tiny, cluttered barcode that fails to scan on mobile cameras.
+
+In this developer guide, we will analyze the vCard specification RFC standards, calculate maximum 2D barcode payload capacity, and write a TypeScript contact card optimizer that compresses vCard data for instant scannability.
+
+---
+
+## 1. Breakdown of the vCard Specification Standards
+
+A vCard used in a **vcard qr code generator** is a plain-text MIME directory format storing contact details line-by-line using `KEY:VALUE` properties.
+
+### vCard 3.0 (RFC 2426) vs. vCard 4.0 (RFC 6350)
+
+```
+┌───────────────────────────┬─────────────────────────────┬─────────────────────────────┐
+│ Feature                   │ vCard 3.0 (RFC 2426)        │ vCard 4.0 (RFC 6350)        │
+├───────────────────────────┼─────────────────────────────┼─────────────────────────────┤
+│ Mobile OS Compatibility   │ 100% Universal (iOS & Android)│ ~85% (Fails on older OS)    │
+│ Character Encoding         │ UTF-8 / Quoted-Printable    │ Mandatory UTF-8             │
+│ Preferred Recommendation │ ✅ BEST for QR Code Barcodes │ ⚠️ Use with caution        │
+└───────────────────────────┴─────────────────────────────┴─────────────────────────────┘
+```
+
+> **Important Developer Note**: Always target **vCard 3.0** when building a **free vcard qr code generator** that embeds data directly into static QR codes. Native camera scanner parsers on older Android versions and non-standard camera apps frequently fail to recognize vCard 4.0 properties.
+
+### Standard vCard 3.0 Structure Example:
+
+```text
+BEGIN:VCARD
+VERSION:3.0
+N:Knuth;Timo;;;
+FN:Timo Knuth
+ORG:QR Master
+TITLE:Lead Software Architect
+TEL;TYPE=CELL,VOICE:+15550192834
+EMAIL;TYPE=INTERNET,PREF:timo@qrmaster.net
+URL:https://www.qrmaster.net
+ADR;TYPE=WORK:;;100 Tech Way;San Francisco;CA;94107;USA
+END:VCARD
+```
+
+---
+
+## 2. QR Code Capacity Limits & The Matrix Density Problem
+
+QR codes have 40 discrete matrix sizes (Version 1 to Version 40). As byte payload increases, matrix size grows exponentially:
+
+```
+┌─────────┬──────────────┬─────────────────────────┬────────────────────────────────┐
+│ Version │ Matrix Grid  │ Max Bytes (Level M)     │ Scan Usability on Business Cards│
+├─────────┼──────────────┼─────────────────────────┼────────────────────────────────┤
+│ Ver 3   │ 29 x 29      │ 53 bytes                │ Super Fast (Instant)           │
+│ Ver 6   │ 41 x 41      │ 134 bytes               │ Excellent                      │
+│ Ver 11  │ 61 x 61      │ 321 bytes               │ Good (Standard vCard max)      │
+│ Ver 20  │ 97 x 97      │ 858 bytes               │ Sluggish / Requires Closeup    │
+│ Ver 40  │ 177 x 177    │ 2,331 bytes             │ Fails on printed cards         │
+└─────────┴──────────────┴─────────────────────────┴────────────────────────────────┘
+```
+
+### The Physical Print Limit Rule for Business Cards
+On a standard $85\text{ mm} \times 55\text{ mm}$ printed business card, a QR code created with a **qr code business card free** generator printed smaller than $20\text{ mm} \times 20\text{ mm}$ should **never exceed Version 10 (600 bytes)**. Encoding full profile photos (BASE64 strings) directly into a static vCard QR code requires over 5,000 bytes, which exceeds maximum QR capacity entirely!
+
+---
+
+## 3. Building a TypeScript vCard Optimizer & Sanitizer
+
+To guarantee fast scans, we can build a utility class in TypeScript for a **qr code generator contact card** that formats vCard properties, strips unnecessary whitespace, sanitizes multi-byte characters, and compresses payload size.
+
+### Step 3.1: vCard Builder Implementation (`src/services/vcardOptimizer.ts`)
+
+```typescript
+export interface ContactFields {
+  firstName: string;
+  lastName: string;
+  organization?: string;
+  title?: string;
+  phoneCell?: string;
+  phoneWork?: string;
+  email?: string;
+  url?: string;
+  city?: string;
+  country?: string;
+}
+
+export class VCardOptimizer {
+  /**
+   * Generates a clean, byte-optimized vCard 3.0 string for a vcard qr code generator.
+   */
+  public static buildOptimizedVCard(fields: ContactFields): string {
+    const lines: string[] = [];
+
+    // Header
+    lines.push('BEGIN:VCARD');
+    lines.push('VERSION:3.0');
+
+    // Structured Name (N:LastName;FirstName;;;)
+    const last = this.cleanText(fields.lastName || '');
+    const first = this.cleanText(fields.firstName || '');
+    lines.push(`N:${last};${first};;;`);
+
+    // Formatted Name (FN:FirstName LastName)
+    const fullName = `${first} ${last}`.trim();
+    lines.push(`FN:${fullName}`);
+
+    // Optional Fields (Only append if non-empty to conserve bytes)
+    if (fields.organization) {
+      lines.push(`ORG:${this.cleanText(fields.organization)}`);
+    }
+
+    if (fields.title) {
+      lines.push(`TITLE:${this.cleanText(fields.title)}`);
+    }
+
+    if (fields.phoneCell) {
+      lines.push(`TEL;TYPE=CELL:${this.sanitizePhone(fields.phoneCell)}`);
+    }
+
+    if (fields.phoneWork) {
+      lines.push(`TEL;TYPE=WORK:${this.sanitizePhone(fields.phoneWork)}`);
+    }
+
+    if (fields.email) {
+      lines.push(`EMAIL;TYPE=INTERNET:${fields.email.trim()}`);
+    }
+
+    if (fields.url) {
+      lines.push(`URL:${fields.url.trim()}`);
+    }
+
+    if (fields.city || fields.country) {
+      const city = this.cleanText(fields.city || '');
+      const country = this.cleanText(fields.country || '');
+      lines.push(`ADR;TYPE=WORK:;;;${city};;;${country}`);
+    }
+
+    // Footer
+    lines.push('END:VCARD');
+
+    // Join with standard CRLF (\r\n) as specified by RFC 2426
+    return lines.join('\r\n');
+  }
+
+  private static sanitizePhone(phone: string): string {
+    return phone.replace(/[^\d+]/g, '');
+  }
+
+  private static cleanText(str: string): string {
+    return str
+      .trim()
+      .replace(/\\/g, '\\\\')
+      .replace(/;/g, '\\;')
+      .replace(/,/g, '\\,')
+      .replace(/\n/g, ' ');
+  }
+
+  public static getByteSize(vcardString: string): number {
+    return Buffer.byteLength(vcardString, 'utf8');
+  }
+}
+```
+
+---
+
+## 4. Static vCard vs. Dynamic Business Card Landing Pages
+
+When building a **qr code generator for business cards**, developers face a choice between two architectures:
+
+```
+┌───────────────────────────────────────┬───────────────────────────────────────┐
+│ Static vCard QR Code                  │ Dynamic Business Card Landing Page     │
+├───────────────────────────────────────┼───────────────────────────────────────┤
+│ Data stored directly inside QR matrix │ Encodes short URL (e.g. /c/timo)      │
+│ Works 100% offline (no internet needed)│ Requires internet connection          │
+│ Contact data CANNOT be edited         │ Contact data can be updated anytime   │
+│ Limited fields (~300 bytes max)       │ Unlimited fields, photo & social links│
+└───────────────────────────────────────┴───────────────────────────────────────┘
+```
+
+### Strategic Recommendation:
+- Use **Static vCard 3.0** when working offline or when data privacy is paramount (no external server dependency).
+- Use **Dynamic Contact Landing Pages** when you need click analytics, social links, profile photos, or the ability to update details without reprinting cards.
+
+---
+
+## Conclusion
+
+Understanding the vCard RFC 2426 specification and respecting barcode payload byte limits is essential for building a **vcard qr code generator**. By stripping non-essential formatting and targeting vCard 3.0, you ensure instant contact saves on both iOS and Android devices.
+

+# How to Create a Free Wi-Fi QR Code: The Complete Guide for Cafes, Hotels & Home Networks
+
+Tired of spelling out long, complex Wi-Fi passwords to restaurant guests, Airbnb visitors, hotel clients, or home friends?
+
+A **qr wifi** code allows anyone with an iPhone or Android device to point their native camera app at a printed barcode and tap a single banner button to automatically join the network—without typing a single character.
+
+In your Google Keyword Planner data, search queries for `qr wifi` and `print qr code` have exploded with **+900% annual growth**.
+
+In this technical guide, we will walk through the step-by-step process of using a **wifi qr code generator**, explaining string syntax, security protocols (WPA2/WPA3), character escaping rules, and downloading vector SVG graphics to **print a qr code** for physical tabletop stands.
+
+---
+
+## 1. How a Wi-Fi QR Code Works Behind the Scenes
+
+Unlike web URLs that open Safari or Chrome, a Wi-Fi QR code uses a specialized, offline MIME payload format standardized by ZXing.
+
+When a mobile device camera scans a **wifi qr code**, the operating system recognizes the `WIFI:` protocol prefix and hands off the credentials directly to the OS network manager (iOS Wi-Fi Settings / Android Network Manager).
+
+```
+┌────────────────────────────────────────┐
+│ Camera Scans WIFI: Payload String      │
+└───────────────────┬────────────────────┘
+                    │
+                    ▼
+┌────────────────────────────────────────┐
+│ OS Displays Modal Banner:              │
+│ "Join 'Cafe_Guest' Wi-Fi Network?"     │
+└───────────────────┬────────────────────┘
+                    │
+                    ▼
+┌────────────────────────────────────────┐
+│ User Taps Banner ➔ One-Tap Auto Connect│
+└────────────────────────────────────────┘
+```
+
+Because a Wi-Fi code stores network credentials directly in the matrix, it uses a **free static qr code generator**. It operates 100% offline—meaning guests can scan and connect even when cellular data coverage is unavailable inside a basement venue!
+
+---
+
+## 2. Step-by-Step Guide to Creating a Wi-Fi QR Code
+
+### Step 1: Collect Your Exact Network Credentials
+To generate a valid code, gather three exact values from your router or network admin panel:
+1. **Network Name (SSID)**: The exact case-sensitive name broadcasted by your router (e.g., `Lounge_Guest_5G`).
+2. **Password (Pre-shared Key)**: The exact Wi-Fi password.
+3. **Security Encryption Type**:
+   - `WPA/WPA2/WPA3` (Standard for ~98% of modern home and business routers).
+   - `WEP` (Legacy encryption).
+   - `Open / None` (Unencrypted public networks).
+
+---
+
+### Step 2: Format the String with Proper Escaping
+
+If your SSID or Wi-Fi password contains special characters like colons (`:`), semicolons (`;`), backslashes (`\`), or commas (`,`), you must escape them with a backslash.
+
+#### Protocol Syntax Template:
+```text
+WIFI:S:<SSID>;T:<SECURITY>;P:<PASSWORD>;;
+```
+
+#### Example Formats:
+
+```text
+# Standard WPA2/WPA3 Home Network
+WIFI:S:MyHomeWiFi;T:WPA;P:SecretPass2026;;
+
+# Cafe Network with a Semicolon in the SSID ("Cafe;Lounge")
+WIFI:S:Cafe\;Lounge;T:WPA;P:coffee123;;
+
+# Free Open Public Network (No Password)
+WIFI:S:Airport_Free_WiFi;T:nopass;;
+```
+
+> **Crucial Rule**: Notice the two semicolons (`;;`) at the end of the string. Leaving out the double semicolon will cause iOS Camera apps to fail to parse the barcode!
+
+---
+
+## 3. How to Print a QR Code for Physical Venues
+
+Generating the digital image is only half the battle. When you **print a qr code** for physical tabletop signs or wall posters, follow these print specifications:
+
+```
+┌───────────────────────────┬───────────────────────────────────────────┐
+│ Print Guideline           │ Recommended Specification                 │
+├───────────────────────────┼───────────────────────────────────────────┤
+│ File Export Format        │ Vector SVG (Scalable, non-pixelated)      │
+│ Minimum Physical Size     │ 3 cm x 3 cm (1.2 in x 1.2 in)             │
+│ Quiet Zone Margin         │ At least 4 modules of whitespace border   │
+│ Contrast Ratio            │ Dark modules on a clean white background  │
+└───────────────────────────┴───────────────────────────────────────────┘
+```
+
+### Printable Tabletop Sign Template (HTML/CSS)
+
+You can copy and save this HTML template to print professional Wi-Fi stand cards for your business:
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+<head>
+  <meta charset="UTF-8">
+  <title>Wi-Fi Access Tabletop Stand</title>
+  <style>
+    @media print { body { -webkit-print-color-adjust: exact; } }
+    body { font-family: 'Inter', system-ui, sans-serif; display: flex; justify-content: center; align-items: center; min-height: 100vh; background: #F8FAFC; margin: 0; }
+    .stand-card { background: white; width: 300px; padding: 32px 24px; border-radius: 16px; box-shadow: 0 10px 25px rgba(0,0,0,0.08); text-align: center; border: 1px solid #E2E8F0; }
+    h1 { font-size: 20px; color: #0F172A; margin: 0 0 6px; }
+    p.sub { color: #64748B; font-size: 13px; margin: 0 0 20px; }
+    .qr-box { background: #F1F5F9; padding: 16px; border-radius: 12px; display: inline-block; margin-bottom: 20px; }
+    .info { background: #F8FAFC; padding: 12px; border-radius: 8px; border: 1px solid #E2E8F0; font-size: 12px; text-align: left; }
+    .row { display: flex; justify-content: space-between; margin-bottom: 4px; }
+    .row:last-child { margin-bottom: 0; }
+    .lbl { color: #64748B; }
+    .val { color: #0F172A; font-weight: 600; font-family: monospace; }
+  </style>
+</head>
+<body>
+  <div class="stand-card">
+    <h1>Free Wi-Fi Access</h1>
+    <p class="sub">Scan with phone camera to connect</p>
+
+    <div class="qr-box">
+      <!-- Insert SVG QR Code Here -->
+      <svg width="180" height="180" viewBox="0 0 180 180">
+        <!-- SVG Paths -->
+      </svg>
+    </div>
+
+    <div class="info">
+      <div class="row"><span class="lbl">SSID:</span><span class="val">Guest_WiFi</span></div>
+      <div class="row"><span class="lbl">Pass:</span><span class="val">Welcome2026</span></div>
+    </div>
+  </div>
+</body>
+</html>
+```
+
+---
+
+## 4. Programmatic Implementation: Wi-Fi Generator in TypeScript
+
+Below is a TypeScript module that constructs escaped Wi-Fi strings and generates vector SVG barcodes automatically.
+
+```typescript
+import QRCode from 'qrcode';
+
+export interface WifiParams {
+  ssid: string;
+  password?: string;
+  security: 'WPA' | 'WEP' | 'nopass';
+  hidden?: boolean;
+}
+
+export class WifiQrEngine {
+  /**
+   * Builds an escaped WIFI: URI payload and renders vector SVG.
+   */
+  public static async generateWifiSvg(params: WifiParams): Promise<string> {
+    const { ssid, password = '', security, hidden = false } = params;
+
+    if (!ssid) throw new Error('SSID is mandatory.');
+    if (security !== 'nopass' && !password) throw new Error('Password is required.');
+
+    // Escape special characters: colons, semicolons, backslashes, commas
+    const cleanSsid = ssid.replace(/([\\;:,])/g, '\\$1');
+    const cleanPass = password.replace(/([\\;:,])/g, '\\$1');
+
+    let payload = `WIFI:S:${cleanSsid};T:${security};`;
+    if (security !== 'nopass') payload += `P:${cleanPass};`;
+    if (hidden) payload += `H:true;`;
+    payload += ';;'; // Double semicolon termination
+
+    // Generate static SVG
+    return await QRCode.toString(payload, {
+      type: 'svg',
+      errorCorrectionLevel: 'M',
+      margin: 4,
+      color: { dark: '#0F172A', light: '#FFFFFF' },
+    });
+  }
+}
+```
+
+---
+
+## Conclusion
+
+Using a **wifi qr code generator** transforms the frustrating experience of typing Wi-Fi passwords into a seamless, one-tap camera interaction. By using static SVG vector files when you **print a qr code**, your guest Wi-Fi access signs remain scannable for years without extra maintenance.

+# Wi-Fi QR Code Protocol: WIFI: String Syntax Specification & Mobile OS Parsing
+
+Scanning a **qr wifi** code to automatically connect a smartphone to a Wi-Fi network without manually typing complex WPA3 passwords is one of the most common physical tech interactions.
+
+Unlike vCards or geo-locations which have formal IETF RFC standards, a **wifi qr code generator** uses an de facto industry standard string syntax originally popularized by ZXing ("Zebra Crossing").
+
+In this technical guide, we will inspect the exact `WIFI:` connection string syntax, character escaping rules, WPA2/WPA3 security flags, hidden network parameters, and build a TypeScript utility to generate a **print qr code** for physical tabletop stands using a **free static qr code generator**.
+
+---
+
+## 1. The `WIFI:` String Protocol Syntax
+
+The payload generated by a **wifi qr code generator** is a formatted key-value string prefixed with `WIFI:`.
+
+### Protocol Format:
+```text
+WIFI:S:<SSID>;T:<SECURITY_TYPE>;P:<PASSWORD>;H:<HIDDEN_FLAG>;;
+```
+
+### Parameter Specification:
+
+| Parameter Key | Description | Allowed Values | Required? |
+|---|---|---|---|
+| **S** | Network SSID (Name) | Any string (UTF-8) | ✅ Mandatory |
+| **T** | Security Encryption Type | `WPA`, `WEP`, `nopass` | ✅ Mandatory |
+| **P** | Pre-shared Key (Password) | Network password string | Conditional (Skip if `nopass`) |
+| **H** | Hidden SSID Flag | `true` or `false` | Optional (Default: `false`) |
+
+---
+
+## 2. Character Escaping Rules: Avoiding Connection Failures
+
+The most frequent bug when building a **wifi qr code generator** is failing to escape special delimiter characters in the SSID or Password.
+
+### Characters Requiring Backslash Escaping (`\`):
+If an SSID or Wi-Fi password contains any of the following four characters:
+- Colon `:`
+- Semicolon `;`
+- Backslash `\`
+- Comma `,`
+
+They **must be escaped with a preceding backslash (`\`)**.
+
+### Escaping Examples:
+
+```text
+# Example 1: SSID containing a semicolon ("Coffee;Bar") and password "secret:123"
+WIFI:S:Coffee\;Bar;T:WPA;P:secret\:123;;
+
+# Example 2: Unencrypted Open Network ("Guest_WiFi")
+WIFI:S:Guest_WiFi;T:nopass;;
+
+# Example 3: Hidden WPA2/WPA3 Network ("Vault") with password "P@$$w0rd"
+WIFI:S:Vault;T:WPA;P:P@$$w0rd;H:true;;
+```
+
+> **Important**: Notice the double semicolon (`;;`) at the very end of the string. Mobile camera scanners use the trailing double semicolon as the string termination marker when parsing **qr wifi** codes!
+
+---
+
+## 3. iOS vs. Android OS Parser Behavior
+
+Understanding how mobile operating systems parse `WIFI:` barcodes prevents support headaches when users **print a qr code**.

+
+## 4. TypeScript Implementation: Wi-Fi Payload Generator
+
+Below is a complete, production-ready TypeScript utility class that formats, escapes, and validates payloads for a **free static qr code generator**.
+
+### `src/services/wifiPayloadBuilder.ts`
+
+```typescript
+export type WifiSecurityType = 'WPA' | 'WEP' | 'nopass';
+
+export interface WifiConfig {
+  ssid: string;
+  password?: string;
+  securityType: WifiSecurityType;
+  isHidden?: boolean;
+}
+
+export class WifiPayloadBuilder {
+  /**
+   * Generates a fully escaped, validated WIFI: connection string.
+   */
+  public static buildPayload(config: WifiConfig): string {
+    const { ssid, password = '', securityType, isHidden = false } = config;
+
+    if (!ssid || ssid.trim().length === 0) {
+      throw new Error('Wi-Fi SSID is mandatory.');
+    }
+
+    if (securityType !== 'nopass' && (!password || password.length === 0)) {
+      throw new Error(`Password is required for security type "${securityType}".`);
+    }
+
+    // Escape special delimiter characters
+    const escapedSSID = this.escapeString(ssid);
+    const escapedPassword = securityType !== 'nopass' ? this.escapeString(password) : '';
+
+    let payload = `WIFI:S:${escapedSSID};T:${securityType};`;
+
+    if (securityType !== 'nopass') {
+      payload += `P:${escapedPassword};`;
+    }
+
+    if (isHidden) {
+      payload += `H:true;`;
+    }
+
+    // Append compulsory double-semicolon termination marker
+    payload += ';';
+
+    return payload;
+  }
+
+  private static escapeString(str: string): string {
+    return str.replace(/([\\;:,])/g, '\\$1');
+  }
+
+  public static isValidWifiPayload(payload: string): boolean {
+    return payload.startsWith('WIFI:') && payload.endsWith(';;');
+  }
+}
+```

+## 5. How to Print a QR Code: Printable Wi-Fi Tabletop Sign Template
+
+When you **print a qr code** for physical venues (hotels, cafes, coworking spaces), pairing the vector barcode with clean printable HTML typography ensures guests know how to scan **qr wifi**.
+
+### Example Printable HTML Template (`public/wifi-stand-card.html`):
+
+```html
+<!DOCTYPE html>
+<html lang="en">
+<head>
+  <meta charset="UTF-8">
+  <title>Wi-Fi Access Sign - Print QR Code</title>
+  <style>
+    @media print { body { -webkit-print-color-adjust: exact; } }
+    body { font-family: 'Inter', system-ui, sans-serif; display: flex; justify-content: center; align-items: center; min-height: 100vh; background: #F8FAFC; margin: 0; }

+    h1 { font-size: 22px; color: #0F172A; margin: 0 0 6px; }
+    p.subtitle { color: #64748B; font-size: 14px; margin: 0 0 24px; }

+    .info-row:last-child { margin-bottom: 0; }
+    .label { color: #64748B; font-weight: 500; }
+    .val { color: #0F172A; font-weight: 600; font-family: monospace; }
+  </style>
+</head>
+<body>
+  <div class="card">
+    <h1>Connect to Wi-Fi</h1>
+    <p class="subtitle">Scan with your phone camera to join</p>
+
+    <div class="qr-container">

+      </div>
+    </div>
+  </div>
+</body>
+</html>
+```
+
+---
+
+## 6. End-to-End Test Suite with Jest
+
+Let's write a unit test suite to verify string escaping and boundary conditions.
+
+### `tests/wifiPayload.test.ts`
+
+```typescript
+import { WifiPayloadBuilder } from '../src/services/wifiPayloadBuilder';
+
+describe('WifiPayloadBuilder', () => {
+  test('should generate standard WPA2 payload', () => {
+    const payload = WifiPayloadBuilder.buildPayload({
+      ssid: 'MyHomeWiFi',
+      password: 'SuperSecretPassword123',
+      securityType: 'WPA',
+    });
+    expect(payload).toBe('WIFI:S:MyHomeWiFi;T:WPA;P:SuperSecretPassword123;;');
+  });
+
+  test('should escape colons and semicolons in SSID and Password', () => {
+    const payload = WifiPayloadBuilder.buildPayload({
+      ssid: 'Cafe;WiFi:5G',
+      password: 'pass;word:123,key\\',
+      securityType: 'WPA',
+    });
+    expect(payload).toBe('WIFI:S:Cafe\\;WiFi\\:5G;T:WPA;P:pass\\;word\\:123\\,key\\\\;;');
+  });
+
+  test('should handle open unencrypted networks', () => {
+    const payload = WifiPayloadBuilder.buildPayload({
+      ssid: 'FreePublicWiFi',
+      securityType: 'nopass',
+    });
+    expect(payload).toBe('WIFI:S:FreePublicWiFi;T:nopass;;');
+  });
+
+  test('should include hidden flag when network is hidden', () => {
+    const payload = WifiPayloadBuilder.buildPayload({
+      ssid: 'HiddenNetwork',
+      password: 'secretpassword',
+      securityType: 'WPA',
+      isHidden: true,
+    });
+    expect(payload).toBe('WIFI:S:HiddenNetwork;T:WPA;P:secretpassword;H:true;;');
+  });
+});
+```
+
+---
+
+## Conclusion
+
+Understanding the `WIFI:` payload specification and implementing strict character escaping in a **wifi qr code generator** ensures seamless, friction-free auto-connections when you **print a qr code** for hotel guests, restaurant customers, and office visitors.

+# Social milestone worker
+
+The app detects QR-code scan milestones and stores customer consent. It does not
+hold X or Meta credentials. The external worker publishes what was approved —
+per channel, never more.
+
+## Consent is bound to a channel
+
+Approving a post on X says nothing about Instagram: different audience,
+different disclosure about the customer's business. Every channel therefore has
+its own checkbox in the dialog, its own text, its own handle and its own row in
+`SocialMilestonePost`. **No row means no consent.** A channel is only offered
+where a publisher is configured — `SOCIAL_MILESTONE_CHANNELS` (app) must stay in
+sync with `SOCIAL_WORKER_CHANNELS` (worker), otherwise approvals pile up in the
+queue with nobody to publish them.
+
+## Test setup (manual SQL only)
+
+1. Apply, in this order, to `qrmaster_test`:
+   [`sql/2026-08-13_social_milestones.sql`](../../sql/2026-08-13_social_milestones.sql),
+   [`sql/2026-08-16_social_milestone_retries.sql`](../../sql/2026-08-16_social_milestone_retries.sql),
+   [`sql/2026-08-16_social_milestone_channels.sql`](../../sql/2026-08-16_social_milestone_channels.sql).
+2. Set distinct `CRON_SECRET` and `INTERNAL_API_SECRET` values in `.env.test`.
+   For an end-to-end test without 1,000 scans, also set
+   `SOCIAL_MILESTONE_THRESHOLDS=1` (or `1,2`). Do not set this on production.
+   Publishing is immediate after consent by default. Set
+   `SOCIAL_MILESTONE_POST_DELAY_HOURS=24` only if a revocation window is desired.
+   Set `SOCIAL_MILESTONE_MIN_GAP_HOURS=0` on test, otherwise the second
+   milestone waits a full day behind the first one.
+3. Deploy using the documented test compose command. `CRON_SECRET` is forwarded
+   to the web service by `docker-compose.yml`.
+4. Trigger detection manually:
+
+```bash
+curl -H "Authorization: Bearer $CRON_SECRET" \
+  https://testmodul.qrmaster.net/api/cron/social-milestones
+```
+
+The detector creates records at 1,000 and 10,000 unique scans only. It is safe
+to call repeatedly because `(qrId, kind)` is unique. A QR code that is already
+past several thresholds on first detection only produces the highest one.
+
+## Queue contract
+
+```bash
+curl -H "Authorization: Bearer $INTERNAL_API_SECRET" \
+  "https://qrmaster.net/api/internal/social-milestones?channel=instagram"
+```
+
+Returns at most one approved post for that channel, claims it, and expects a
+result report for the returned `id`:
+
+```bash
+curl -X PATCH -H "Authorization: Bearer $INTERNAL_API_SECRET" \
+  -H "Content-Type: application/json" \
+  -d '{"id":"<post-id>","result":"posted","postUrl":"https://..."}' \
+  https://qrmaster.net/api/internal/social-milestones
+```
+
+First attempts are spaced by `SOCIAL_MILESTONE_MIN_GAP_HOURS` (default 24) per
+channel, so the brand timeline cannot be flooded when several customers consent
+on the same day. A blocked poll answers
+`{"milestone": null, "reason": "spacing", "nextPostAt": "..."}`.
+
+`milestone.text` is published **verbatim** — it is the text the customer read
+before consenting. The image is not part of the payload: the worker downloads it
+from `<QRMASTER_API_BASE>/s/m/<shareToken>/og`, the same renderer that serves the
+popup and the link preview. `?format=` takes `landscape` (1200×630, default),
+`square` (1080×1080) or `portrait` (1080×1350).
+
+## Instagram
+
+Publishing runs against the QRMaster.net Business account (see
+[social-accounts-and-jobs.md](social-accounts-and-jobs.md)) in three steps:
+`POST /{ig-user-id}/media` → poll `status_code` until `FINISHED` →
+`POST /{ig-user-id}/media_publish`.
+
+Worth knowing before enabling it:
+
+- **JPEG only.** The worker flattens the rendered PNG onto white and uploads it
+  through `POST /api/social-assets`; Meta downloads `image_url` itself, so it has
+  to be publicly readable on the verified domain. `SOCIAL_ASSET_ADMIN_KEY` is the
+  existing `TIKTOK_ADMIN_KEY`.
+- **No clickable links in captions.** The Instagram text therefore ends in
+  hashtags instead of the share URL, and mentions use the customer's Instagram
+  handle, not their X handle.
+- **50 posts / 24 h**, verifiable via `GET /{ig-user-id}/content_publishing_limit`.
+- **Reconciliation is caption-based.** Before a repeated attempt the worker
+  compares the caption against the last 25 media items. Two milestones with an
+  identical caption — same QR title, same scan count — would be treated as the
+  same post; the 24 h spacing makes that combination unlikely but not impossible.
+- Required environment: `SOCIAL_WORKER_CHANNELS=x,instagram`, `INSTAGRAM_USER_ID`,
+  `INSTAGRAM_ACCESS_TOKEN`, plus `SOCIAL_MILESTONE_CHANNELS=x,instagram` on the
+  web service so the dialog asks for it in the first place.
+
+Do not configure this worker against `testmodul`. LinkedIn has no approved
+brand-posting integration in this project. Customers can self-share on all three:
+X opens a prefilled intent, LinkedIn gets the text copied, Instagram opens the
+system share sheet on a phone and falls back to an image download.
+
+## Failed posts
+
+A reported failure — and a claim the worker never confirmed — counts as one
+attempt. The queue re-schedules the post itself after 5, then 10 minutes and only
+parks it in `failed` once three attempts are used up. Before posting again the
+worker reconciles against the account (share token on X, caption on Instagram),
+so a failure reported after a successful post cannot duplicate it.
+
+The consent dialog opens once per milestone, so a customer who has closed it can
+no longer see or restart a failed post from there. Settings → Milestone sharing
+lists every milestone with one line per channel and offers "Try again" (re-queues
+the approved text unchanged) and "Cancel" (revokes that channel before anything
+is published).

 # QR Master Project Summary
 
+## AI SEO Product Positioning
+
+For AI-search and answer-engine optimization, describe QR Master as a complete QR workflow rather than only a dynamic-code platform:
+
+> QR Master offers 20 free QR code generators plus a free barcode generator, then scales into editable dynamic QR codes, scan analytics, custom branding, and CSV/Excel bulk creation.
+
+Facts to preserve consistently across landing pages, `llms.txt`, comparison pages, structured content, and future AI-SEO articles:
+
+- 20 free specialized QR code generators; one additional free barcode generator.
+- Free plan: 3 active dynamic QR codes and unlimited static QR codes.
+- Dynamic QR codes support editable destinations after print and scan tracking.
+- Paid plans add higher dynamic-code limits, advanced analytics, branding, and bulk CSV/Excel workflows.
+
+AI-SEO rule: make the full feature stack explicit and answer-first. Do not reduce QR Master to only “dynamic QR + analytics”; connect free tools, dynamic editing, measurement, branding, and bulk creation in the same concise product description when it is relevant to the query.
+
 ## TikTok Growth Positioning
 
 QR Master should be positioned as control after print, not as another generic QR code generator.

+1. Deutsche, lokalisierte Toolseiten für `QR-Code-Generator`, `dynamischer QR-Code`, `QR-Code-Tracking`, `QR-Code-Scanner` und `QR-Code-Visitenkarte` priorisieren.
+2. Die US-Startseite nicht primär über Barcode- und Wettbewerberbegriffe wachsen lassen; stattdessen klare englische Landingpages für `qr code generator`, `dynamic qr code generator`, `qr code tracking`, `vcard qr code generator` und `bulk qr code generator` stärken.
+3. Jede Toolseite mit direkter Definition, Use Cases, Funktionsvergleich statisch/dynamisch, Tracking-Erklärung, FAQ und starken internen Links ausstatten.
+4. Die bereits auffälligen `/alternatives/bitly`- und `/alternatives/flowcode`-Seiten zu belastbaren Vergleichsseiten mit echten Produktunterschieden ausbauen.
+
+## 2. GreenLens Pro
+
+### USA / Englisch
+
+GreenLens rankt bereits für ein relevantes Pflanzenfoto-/Identifikationsthema, überwiegend über eine Seite:
+
+- `google lens plant identification app` – Volumen 8.100, Position 32, `/plant-identifier-app`
+- `identify a plant by picture` – 8.100, Position 79, `/identify-plant-photo`
+- `identify plant from photo` – 8.100, Position 80
+- `identify plants by picture` – 8.100, Position 55
+- `plant id from photo` – 8.100, Position 55
+- `plant identifier with photo` – 8.100, Position 51
+- `flower picture identifier` – 1.300, Position 74
+- `what plant is this by picture` – 1.000, Position 93
+- `plant finder by photo` – 590, Position 58
+
+### Wichtigste Wettbewerber
+
+picturethisai.com, plantnet.org, plant.id, plantsnap.com, apple.com, myplantin.com, lensapp.io sowie Google, YouTube und Reddit als SERP-/Marken-Ökosystem.
+
+### Keyword-Gaps / Chancen
+
+Die Wettbewerber decken unter anderem ab:
+
+- `plant identification`, `plant identifier`, `plant id`
+- `what type of plant is this`
+- `flower identifier by picture`
+- `plant disease identifier`
+- konkrete Pflanzen- und Symptombegriffe
+
+Die Domain-Intersection-Daten enthalten außerdem viele botanische Informationsbegriffe. Diese sollten nicht ungefiltert als SEO-Ziele übernommen werden: Für GreenLens sind Identifikation, Diagnose und nächste Pflegeschritte wertvoller als reine Pflanzenlexikon-Queries.
+
+### Empfehlung
+
+1. `/identify-plant-photo` als zentrale Money-/Tool-Seite auf Positionen 1–20 entwickeln: klare Antwort, Upload-/Scan-Nutzen, Beispiele, FAQ, App-CTA.
+2. Separat clusterbare Seiten für `plant identifier`, `flower identifier`, `plant disease identifier`, `brown leaves`, `yellow leaves`, `overwatering` und `root rot` aufbauen.
+3. Jede Diagnose-Seite muss sichtbar den nächsten Handlungsschritt erklären; nicht nur Pflanzenwissen liefern.
+4. Interne Links zwischen Identifikation → Diagnose → Pflegeplan → App setzen.
+5. Google-Lens-Vergleich als Trust-/Alternative-Seite nutzen, aber nicht die gesamte Informationsarchitektur auf Wettbewerberbegriffe stützen.
+
+## 3. Entscheidomat
+
+### Deutschland / Deutsch
+
+DataForSEO meldet aktuell **keine Ranked Keywords** für `entscheidomat.com` im deutschen Google-Markt. Das bedeutet nicht automatisch, dass die Website technisch nicht indexiert ist; es bedeutet, dass DataForSEO in diesem Markt keine verwertbaren Ranking-Keywords geliefert hat.
+
+### Wettbewerbs- und Gap-Signale
+
+Vergleichsdaten mit wheelofnames.com, random.org und zufallsgenerator.de zeigen relevante Suchthemen:
+
+- `glücksrad` – Volumen 246.000
+- `zufallsgenerator` – 165.000
+- `würfel` – 90.500
+- `google drehscheibe` – 40.500
+- `wheel of names` – 33.100
+- `spin the wheel` – 33.100
+- `coin flip` – 40.500, englischer/Internationaler Suchbegriff
+
+Ein Teil der Daten von random.org ist für Entscheidomat nicht passend, zum Beispiel Passwortgenerator- und englische Random-Number-Begriffe. Diese wurden als Kontamination verworfen.
+
+### Empfehlung
+
+1. Jede der sieben Funktionen als eigenständige, crawlbare SEO-Landingpage führen: `glücksrad`, `zufallszahl-generator`, `würfel-online`, `münze-werfen`, `ja-nein-generator`, `namen-auslosen`, `magic-8-ball`.
+2. Pro Seite einen sichtbaren Definition-Block direkt unter dem H1 ergänzen.
+3. Suchintention und Tool direkt verbinden: sofort nutzbares Tool plus Erklärung, Beispiele, FAQ und interne Links.
+4. Die Startseite auf `Zufallsgenerator` und `Entscheidungshilfe` fokussieren; nicht alle sieben Begriffe gleich stark in Title/H1 stapeln.
+5. Für `glücksrad`, `zufallsgenerator` und `würfel online` zuerst spezifische SEO- und UX-Landingpages optimieren, weil dort die größte erkennbare Nachfrage liegt.
+
+## Priorisierte Maßnahmen über alle drei Projekte
+
+### Priorität 1 – sofort
+
+- QRMaster: englische und deutsche Kern-Toolseiten auf `qr code generator`, `dynamic qr code`, `qr code tracking` und `QR-Code erstellen` ausrichten.
+- GreenLens: `identify-plant-photo` als zentrale Conversion-/SEO-Seite ausbauen.
+- Entscheidomat: sieben Tools als eindeutige SEO-Seiten mit sichtbarem HTML-Content und sauberem internen Linking absichern.
+
+### Priorität 2 – danach
+
+- Keyword-Mapping erstellen, damit pro Suchintention genau eine kanonische Seite ranken soll.
+- Titles, H1s, Meta-Descriptions und FAQ-Blöcke auf die DataForSEO-Gaps ausrichten.
+- Vergleichsseiten und Use Cases nur dort ausbauen, wo sie einen echten Nutzwert und interne Conversion-Verbindung haben.
+
+### Priorität 3 – Monitoring
+
+- Nach den Änderungen monatlich dieselben DataForSEO-Abfragen wiederholen.
+- Zusätzlich Google Search Console je Domain auswerten; insbesondere bei Entscheidomat ist die Nullmessung ohne GSC nicht ausreichend.
+- Rankings nicht isoliert bewerten: URL, Suchintention, Klicks, Impressions und Conversion gemeinsam messen.
+
+## Technischer Nachweis
+
+Die Live-Abfragen liefen mit HTTP 200 und DataForSEO-Task-Status 20000. Erfolgreich verarbeitet wurden:
+
+- 4 Ranked-Keyword-Abfragen
+- 4 Competitor-Domain-Abfragen
+- 12 Domain-Intersection-Abfragen für Wettbewerber-Gaps
+- 4 Keyword-Metrik-Abfragen für Seed-Cluster
+
+Die Seed-Volume-Antworten wurden von der ersten Auswertung nicht in die Ergebnisliste übernommen, deshalb stammen die im Bericht genannten Volumina aus Ranked-Keyword- und Domain-Intersection-Daten. Die vier Seed-Requests selbst wurden technisch erfolgreich angenommen, werden aber nicht als separate Primärquelle für die genannten Zahlen verwendet.

+# QRMaster SEO Improver Report – 2026-07-29
+
+**Zeitraum:** 2026-06-30 bis 2026-07-27
+**Modus:** report-only; keine Live-Dateien geändert
+
+## Executive Summary
+
+- Search Console lieferte 1310 Query-/Seiten-Zeilen.
+- 15 priorisierte Chancen wurden identifiziert.
+- Die Analyse ist ein Baseline-Lauf; es gibt noch keinen vorherigen SEO-Improver-Report zum Vergleich.
+

+| striking-distance | qr code generator instagram | 19.2 | 62 | 0.00% | https://www.qrmaster.net/tools/instagram-qr-code |
+
+## Empfohlene erste Maßnahmen
+
+1. Die stärkste Striking-Distance-Seite zuerst inhaltlich gegen die aktuelle Suchintention prüfen.
+2. Bei hohen Impressions und niedriger CTR Title und Meta-Description testen, ohne das Hauptkeyword zu entfernen.
+3. Interne Links aus thematisch passenden QRMaster-Seiten auf die priorisierten Zielseiten ergänzen.
+4. Nach der Änderung mindestens einen weiteren Search-Console-Zeitraum abwarten und den Positions-/CTR-Verlauf vergleichen.

+## Blocker und Hinweise
+
+- Dieser Lauf hat keine Website-Dateien, GitHub-Branches oder Live-Konfigurationen verändert.
+- Es wurde keine Vorher-/Nachher-Bewertung durchgeführt, weil dies der Baseline-Lauf ist.
+- Keyword-Suchvolumen ist in der CSV leer, sofern es für die verwendeten DataForSEO-Aufgaben nicht zurückgegeben wurde.

+# SEO Rank Tracker (standalone)
+
+Eigenständiger Rank-Tracker für `qrmaster.net` über die [Serper.dev](https://serper.dev)
+Google-SERP-API. Läuft komplett außerhalb der Next.js-App, greift auf keine
+Datenbank zu und hat keine npm-Dependencies — nur **Node 18+**.
+
+Ersetzt kostenpflichtige Rank-Tracker (Wincher, SerpRobot, ~10–25 €/Monat) für
+ein paar Cent pro Lauf.
+
+## Setup
+
+```bash
+cd seo-tracker
+cp .env.example .env
+# SERPER_API_KEY in .env eintragen
+```
+
+## Nutzung
+
+```bash
+node track.mjs --dry-run          # zeigt Keywords + Credit-Schätzung, ohne API-Calls
+node track.mjs --limit 5 --num 20 # kleiner Testlauf (~10 Credits)
+node track.mjs                    # voller Lauf
+node track.mjs --num 20           # nur Top 20 prüfen — spart 80% Credits
+
+# eigene Liste / eigene Ausgabedatei (z. B. für Ad-hoc-Checks)
+node track.mjs --keywords test.txt --out test.csv --num 20
+```
+
+Ergebnisse werden an `results.csv` angehängt (eine Zeile pro Keyword pro Lauf).
+Beim zweiten Lauf zeigt die Konsole automatisch die Δ-Veränderung gegenüber dem
+vorherigen Durchlauf.
+
+## Keywords pflegen
+
+`keywords.txt`, eine Zeile pro Keyword. `#` = Kommentar.
+Land optional per Pipe anhängen:
+
+```
+qr code generator
+qr code generator kostenlos | de
+```
+
+## Credits im Blick behalten
+
+Serper rechnet **1 Credit pro 10 Ergebnisse** ab:
+
+| Tiefe (`--num`) | Credits/Keyword | 43 Keywords | Läufe mit 2.500 Credits |
+|---|---|---|---|
+| 100 | 10 | 430 | ~5 |
+| 20 | 2 | 86 | ~29 |
+| 10 | 1 | 43 | ~58 |
+
+**Empfehlung:** `RESULTS_PER_QUERY=20` in der `.env` und wöchentlich laufen lassen.
+Damit reicht das kostenlose Guthaben gut ein halbes Jahr, und Positionen jenseits
+von Platz 20 sind ohnehin kaum handlungsrelevant.
+
+Für die tiefe Sicht (Top 100) einmal im Quartal `node track.mjs --num 100` laufen lassen.
+
+## Automatisierung
+
+Wöchentlich, montags 6 Uhr:
+
+**Windows (Aufgabenplanung)**
+```
+schtasks /create /tn "QR Master Rank Tracker" /tr "node C:\Users\timo\Documents\qrmaster\QR-master\seo-tracker\track.mjs" /sc weekly /d MON /st 06:00
+```
+
+**Linux/Server (crontab)**
+```
+0 6 * * 1 cd /pfad/zu/seo-tracker && node track.mjs >> tracker.log 2>&1
+```
+
+## Ausgabe-Spalten
+
+| Spalte | Bedeutung |
+|---|---|
+| `date` | Datum des Laufs |
+| `keyword` / `country` | Abgefragte Query und Land |
+| `position` | Position von qrmaster.net (leer = nicht in Top N) |
+| `url` | Welche URL rankt |
+| `top_competitor` | Domain auf Platz 1 (ausser eigener) |
+| `ai_overview` | 1 = Google zeigte AI Overview / Answer Box |
+| `error` | Fehlermeldung, falls der Call fehlschlug |
+
+Die Spalte `ai_overview` ist der Einstieg ins AEO-Tracking: Keywords, bei denen
+Google eine AI-Antwort ausspielt, verlieren organische Klicks — die gehören
+priorisiert in die AEO-Backlog-Liste in `CLAUDE.md`.
+
+## Blinder Fleck
+
+Der Tracker sieht nur, was Serper sieht — Google-Rankings. Für **echte**
+Impressions/Klicks empfiehlt sich zusätzlich die Google-Search-Console-API
+(kostenlos, offizielle Daten).

+QR MASTER - SQL-BEFEHLE ZUM UMSETZUNGSPLAN VOM 27.07.2026

+POLICY (aus CLAUDE.md): Keine Prisma-Migrationen. Alle Schemaaenderungen werden
+als rohes SQL direkt gegen die laufende PostgreSQL-Instanz ausgefuehrt. Danach
+prisma/schema.prisma von Hand angleichen und "npx prisma generate" laufen
+lassen - niemals "npx prisma migrate".
+
+AUSFUEHREN ueber:

+--     Cron-Lauf bekommen? WICHTIG: ohne Block 3.2 ginge sie an ALLE
+--     Bestandsnutzer mit Scan-Historie, auch an solche, deren erster Scan
+--     Monate zurueckliegt. Das waere kein Anlass mehr, sondern eine
+--     Massenmail unter deinem Namen.

+================================================================================
+
+-- limitReachedNudgeSentAt: Marker fuer die verhaltensbasierte Limit-Mail.
+--   Ersetzt die kalenderbasierte Tag-7-Mail, die heute auch an Nutzer geht,
+--   die das Limit gar nicht erreicht haben.
+-- firstScanNudgeSentAt: Marker fuer die neue "erster Scan"-Mail.

+================================================================================
+
+-- 3.1 Nutzer, die schon am Limit sitzen, haben die Limit-Mail nie bekommen
+--     koennen - es gab sie nicht. Ob sie sie nachtraeglich bekommen sollen,
+--     ist eine Entscheidung:
+--
+--     Variante A - sie sollen die Mail bekommen: dieses Statement NICHT
+--     ausfuehren. Der erste Cron-Lauf schickt sie an alle, die am Limit sind.
+--     Bei vielen Bestandsnutzern ist das ein Versand-Peak.
+--
+--     Variante B - nur Neufaelle ab jetzt: Statement ausfuehren, dann bekommen
+--     bestehende Limit-Faelle keine Mail und die Sequenz startet sauber.
+
+-- Variante B (auskommentiert - bewusst entscheiden und dann aktivieren):
+-- UPDATE "User" u
+-- SET "limitReachedNudgeSentAt" = now()
+-- WHERE u.plan = 'FREE'
+--   AND (SELECT COUNT(*) FROM "QRCode" q
+--        WHERE q."userId" = u.id AND q.type = 'DYNAMIC' AND q.status = 'ACTIVE') >= 3;
+
+-- 3.2 PFLICHT: Bestandsnutzer, deren erster Scan laenger als 7 Tage her ist,
+--     als "bereits benachrichtigt" markieren. Ohne dieses Statement geht die
+--     "erster Scan"-Mail beim ersten Lauf an die gesamte Bestandsbasis - mit
+--     einem Anlass, der Monate zurueckliegt.
