transfermarkt.es — Global SEODiff Score 43/100

transfermarkt.es
📊

The AI-Readiness score for transfermarkt.es stands at a concerning 15/100, placing it among the least AI-accessible sites in the index. Within the infrastructure vertical, this places transfermarkt.es below the industry average of 57 —, 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 token bloat ratio sits at a lean 4.5×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. Only 1 schema block is present — adding Organization, WebSite, and Breadcrumb schemas would significantly improve structured data coverage. With only minimal AI bot access, the domain is largely invisible to the ecosystem of AI-driven discovery tools.

Fastest improvements

  • Allow GPTBot in robots.txt so AI crawlers can access your pages (see Crawl Access).
  • Allow ClaudeBot (many assistants rely on it) — blocking it often correlates with “AI invisibility.”
  • 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 →
