 ## Overview
 The official website for Folx Music Television (folx.tv). Dark-themed bento grid layout with content for folk music (Volksmusik/Schlager) fans. Features articles, videos, photo gallery, horoscope widget + subpage, recipe widget + subpage, Google News feed, and integrated AdSense ads. All content is hardcoded in seed for production deployments.
 
+## SEO
+- Primary keyword: "Volksmusik" — used across all page titles, meta descriptions, OG tags, and structured data
+- Dynamic canonical URLs via `usePageMeta` hook (updates `<link rel="canonical">` per page)
+- SSR article pages: server-side meta tags (OG, Twitter, description, keywords, canonical) in both `server/vite.ts` (dev) and `server/static.ts` (prod)
+- `stripExistingMeta()` removes duplicate meta/canonical from base HTML before injecting article-specific ones
+- JSON-LD structured data: WebSite (home) with SearchAction, NewsArticle + BreadcrumbList (articles)
+- Sitemap at `/sitemap.xml` — includes all static pages, categories, horoscope signs, and articles
+- robots.txt disallows `/api/`, `/search`, `/admin/`
+- H1 tag on home page (sr-only): "FOLX TV – Volksmusik & Schlager Fernsehsender"
+- Logo alt text includes "Volksmusik & Schlager Fernsehsender"
