+# SEO Plan April 2026 — qrmaster.net
+**Bewertung aktuell: 89/100 → Ziel mit Ergänzungen: 93–95/100**
+
+---
+
+## Übersicht
+
+Basis: Google Keyword Planner Daten (vollständig in `seo-keywords.csv`).
+
+Drei Cluster mit stärkstem Potenzial:
+- **Cluster 1 – Dynamic QR**: 1k–10k/mo, Mittel competition, CPCs bis €30
+- **Cluster 2 – Analytics/Tracking**: 1k–10k/mo, +900% YoY Trend, höchste CPCs im Datensatz (€34 für "trackable qr code")
+- **Cluster 3 – Custom QR + vCard**: 1k–10k/mo per Keyword, teils Gering competition, alle Tools bereits live
+
+Sechs Strategien:
+- **A** – Interne Verlinkung fixen (6 Dateien, 0 neue Seiten)
+- **B** – 3 fehlende Seiten erstellen
+- **C** – Structured Data für `/reprint-calculator` (einzige kritische Lücke)
+- **D** – SERP-Differenzierung (unique angle pro Seite)
+- **E** – Post-Launch Measurement
+- **F** – Authority Support pro neue Seite
+
+---
+

+## B: Neue Seiten
+
+### B3 (Prio 1): `/blog/static-vs-dynamic-qr-code`
+
+**Keywords:** `static qr codes` (1k–10k, +900%) + ~15 Long-Tail "can you change a qr code link" Keywords (je 10–100/mo)
+
+**Unique Angle:** Einziger Artikel der echte Reprint-Kosten mit konkreten Zahlen zeigt (z.B. "500 Flyer × 3 Reprints = €X") — direkt verlinkt auf `/reprint-calculator`. Andere Seiten haben nur Erklärungen, keine Zahlen.
+
+**Datei:** Blog-Eintrag im bestehenden Blog-System unter `/blog/static-vs-dynamic-qr-code`
+
+**Pflicht-Sektionen:**
+- H1: "Static vs Dynamic QR Code: What's the Difference and Which Do You Need?"
+- Quick Summary oben (≤3 Sätze, AI-zitierbar)
+- Vergleichstabelle (5–7 Features inkl. Kosten)
+- Wann Static nutzen / Wann Dynamic nutzen
+- Echte Reprint-Kosten-Beispiele → Link auf `/reprint-calculator`
+- FAQ (min. 7 Items für alle "can you change / edit / redirect a qr code" Queries)
+- GrowthLinksSection → `/dynamic-qr-code-generator`, `/reprint-calculator`, `/qr-code-tracking`
+
+**Schema:** Article + FAQPage + BreadcrumbList
+
+---
+
+### B1 (Prio 2): `/tools/google-review-qr-code`
+
+**Keywords:** `qr code generator for google reviews` (1k–10k, **Gering**, **+900%**) + `qr code for google reviews` (1k–10k, Hoch)
+
+**Unique Angle:** "How to find your Google Review link" mit konkretem Step-by-Step Screenshot-Flow. Das hat kaum eine andere QR-Tool-Seite.
+
+**Dateien:**
+- `src/app/(main)/(marketing)/tools/google-review-qr-code/page.tsx`
+- `src/app/(main)/(marketing)/tools/google-review-qr-code/GoogleReviewGenerator.tsx`
+
+**Muster:** `/tools/url-qr-code/page.tsx` (inline JSON-LD Pattern)
+
+**Pflicht-Sektionen:**
+- H1: "Google Review QR Code Generator — Free"
+- AnswerFirstBlock (Was es ist, Wann nutzen, 3 Schritte)
+- Schritt-für-Schritt Anleitung: Eigenen Google Review Link finden (Google Maps → Teilen → Link kopieren)
+- Use Cases: Restaurant, Hotel, Klinik, Einzelhandel
+- FAQ (min. 5 Items)
+- GrowthLinksSection → `/qr-code-for/restaurants`, `/qr-code-for/hotels`, `/dynamic-qr-code-generator`, `/qr-code-tracking`
+
+**Schema:** SoftwareApplication + HowTo + FAQPage + BreadcrumbList
+
+**Local Business Cluster-Verbindung (Strategie F):**
+- Von dieser Seite linken: `/qr-code-for/restaurants`, `/qr-code-for/hotels`, `/qr-code-for/clinics`
+- Diese Seiten zurück linken: "Manage your Google reviews with a QR code"
+
+---
+
+### B2 (Prio 3): `/qr-code-print-size-guide`
+
+**Keywords:** `minimum qr code size` (1k–10k, **Gering**), `qr code print size` (10–100, Gering)
+
+**Unique Angle:** "Recommended size by scan distance" Tabelle — Visitenkarte (5cm, Abstand 15cm) vs. Poster (10cm, Abstand 1m) vs. Billboard (20cm+, Abstand 5m+). Konkrete Information die nirgends gut dokumentiert ist.
+
+**Datei:** `src/app/(main)/(marketing)/qr-code-print-size-guide/page.tsx`
+
+**Format: Utility Content Hybrid** (kein reiner Guide):
+- Schnell-Antwort-Tabelle: Größe nach Oberfläche + Scan-Abstand
+- Visuelle Größentabelle (CSS/SVG)
+- DPI-Anforderungen für Print
+- Downloadable Cheat Sheet (PDF oder druckbare Tabelle) als Share-Hook
+- FAQ (min. 5 Items)
+- GrowthLinksSection → `/reprint-calculator`, `/dynamic-qr-code-generator`, `/custom-qr-code-generator`
+
+**Schema:** Article + FAQPage + BreadcrumbList

+## C: Structured Data
+
+### Einzige kritische Lücke: `/reprint-calculator/page.tsx`
+
+Alle anderen Commercial Pages nutzen `SeoJsonLd` oder `UseCasePageTemplate` (rendert Schemas intern). Der Reprint Calculator hat **null Structured Data**.
+

+```tsx
