nerfstars.com — Global SEODiff Score 22/100

nerfstars.com
📊

nerfstars.com registers just 15/100 on the ACRI scale — a bottom-tier result indicating systemic AI visibility problems. Within the infrastructure vertical, this places nerfstars.com below the industry average of 57 —, indicating room for competitive improvement. Content is delivered server-side, meaning bots and AI agents can parse the full page without executing JavaScript. A 14.6× bloat ratio is typical for sites in this tech tier — not wasteful, but streamlining could further boost extractability. Minimal structured data (1 block) limits the site's ability to communicate entity relationships to AI systems. All major AI crawlers (GPTBot, ClaudeBot, CCBot, Google-Extended) are blocked by robots.txt — the site is effectively invisible to AI search.

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 →

💡BreadcrumbList schema missing. AI cannot understand your site hierarchy or how pages relate to each other.
