foresthistory.org — Global SEODiff Score 42/100

foresthistory.org
📊

foresthistory.org registers just 15/100 on the ACRI scale — a bottom-tier result indicating systemic AI visibility problems. Compared to other infrastructure sites (avg score: 58), foresthistory.org is trailing the benchmark, indicating room for competitive improvement. The low ghost ratio (0%) confirms that what crawlers see matches what users see — a hallmark of strong SSR implementation. A 50.0× token bloat ratio means crawlers must process significantly more tokens to reach the actual content — a drag on extraction efficiency. Minimal structured data (1 block) limits the site's ability to communicate entity relationships to AI systems. Comprehensive AI crawler restrictions limit this domain's presence in the growing AI search ecosystem.

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 →
