nanboya.com — Global SEODiff Score 68/100

nanboya.com
📊

nanboya.com shows strong AI visibility with an ACRI of 76/100, outperforming 83% of indexed domains. Compared to other infrastructure sites (avg score: 57), nanboya.com performs above the benchmark, suggesting strong competitive positioning in AI search. Content is delivered server-side, meaning bots and AI agents can parse the full page without executing JavaScript. The token bloat ratio sits at a lean 4.7×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. The site includes 3 schema blocks, providing adequate structured data for basic entity recognition. Some AI crawlers are permitted while others are blocked — a mixed robots.txt policy that limits visibility in certain AI ecosystems.

  • 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 →
