csfd.cz — Global SEODiff Score 56/100

csfd.cz
📊

csfd.cz scores 54/100 on the AI-Readiness Index, placing it in the middle tier of indexed domains — there is clear room for improvement. Within the infrastructure vertical, this places csfd.cz below the industry average of 58 —, indicating room for competitive improvement. The low ghost ratio (5%) confirms that what crawlers see matches what users see — a hallmark of strong SSR implementation. The 5.5× token bloat ratio falls within the normal range, though there is room to trim navigation, footer, and script overhead. No structured data was detected, which means AI systems must infer all entities and relationships from raw HTML alone. Partial bot access means the domain is visible to some AI systems but invisible to others — ClaudeBot remain blocked.

Fastest improvements

  • Allow ClaudeBot (many assistants rely on it) — blocking it often correlates with “AI invisibility.”
  • Add basic Organization and WebSite JSON-LD to fix “0 schema blocks” (see Schema Coverage).
  • Reduce token bloat (navigation/footer/code) so agents reach your main content faster (see Token Bloat).
  • Create an llms.txt file so AI crawlers can discover your content structure without heavy crawling. Generate llms.txt →
  • Run a full entropy audit to find which DOM regions waste the most tokens. Run Entropy Audit →
