historyorb.com — Global SEODiff Score 49/100

historyorb.com
📊

The AI-Readiness score for historyorb.com stands at a concerning 15/100, placing it among the least AI-accessible sites in the index. Compared to other saas sites (avg score: 57), historyorb.com is trailing the benchmark, indicating room for competitive improvement. While the majority of content is server-rendered, the 15% ghost ratio suggests some content remains invisible to static crawlers. The 9.6× token bloat ratio falls within the normal range, though there is room to trim navigation, footer, and script overhead. Minimal structured data (1 block) limits the site's ability to communicate entity relationships to AI systems. A total AI bot blockade means no AI-powered search or answer engine can crawl and index this domain's content.

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 →
