+### SEO Implementation Notes (Marketing)
+- **Source of tags**: `resources/js/layouts/mainWebsite.tsx` renders canonical + hreflang links for Inertia marketing pages.
+- **URL building**: `resources/js/lib/localizedPath.ts` handles locale rewrites (e.g., `/kontakt` ↔ `/contact`) and prefixing.
+- **Data inputs**: `supportedLocales`, `locale`, and `appUrl` are shared via `app/Http/Middleware/HandleInertiaRequests.php`.
+- **SSR**: Inertia SSR is disabled (`config/inertia.php`), so canonical/hreflang tags are client-rendered.
+
+### Validation Checklist (Search Console + Lighthouse)
+- Verify canonical + hreflang output on key marketing pages (home, contact, packages, blog, occasions).
+- Use Search Console URL inspection to confirm rendered HTML contains canonical + hreflang tags.
+- Run Lighthouse SEO audit on both `/de/*` and `/en/*` routes (spot-check canonical + alternate links).
+
+### Tests
+- **Vitest**: `resources/js/layouts/__tests__/mainWebsite.seo.test.tsx` validates canonical/hreflang output and localized slug rewrites.

 ## Migration from PHP to JSON
 - Extract keys from `resources/lang/\{locale\}/marketing.php` to `public/lang/\{locale\}/marketing.json`.
 - Consolidate: Remove duplicates; use nested objects (e.g., `{ "header": { "login": "Anmelden" } }`).

 - **Fonts & Assets**: Vite-Plugin für Fonts/SVGs; preload in Layout.
+- **SEO (hreflang/canonical)**: `resources/js/layouts/mainWebsite.tsx` rendert canonical + hreflang auf Basis von `supportedLocales`, `locale`, `appUrl` und `resources/js/lib/localizedPath.ts` (Locale-Rewrites).
 - **Analytics (Matomo)**: Aktivierung via `.env` (`MATOMO_ENABLED=true`, `MATOMO_URL`, `MATOMO_SITE_ID`). `AppServiceProvider` teilt die Konfiguration als `analytics.matomo`; `MarketingLayout` rendert `MatomoTracker`, der das Snippet aus `/docs/piwik-trackingcode.txt` nur bei erteilter Analyse-Zustimmung lädt, `disableCookies` setzt und bei jedem Inertia-Navigationsevent `trackPageView` sendet. Ein lokalisierter Consent-Banner (DE/EN) übernimmt die DSGVO-konforme Einwilligung und ist über den Footer erneut erreichbar.
 - **Tests**: E2E mit Playwright (z.B. navigate to /packages, check header/footer presence).
