How this service works
AI crawler visibility audit: is your website visible to AI crawlers (GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot) so ChatGPT, Claude and Perplexity can read and cite it? Fetched like an AI crawler, without JavaScript: robots.txt, llms.txt, sitemap, soft 404, JSON-LD, and which crawlers are blocked at the edge. $0.10 per check, one payment per check: every rule, a model verdict, a fix with evidence for every finding. Pass: a dated badge and a registry listing. No account, no human.
Output
Returns a numeric visibility score, categorized findings grouped by severity, and the five most critical issues (empty JS shell, soft 404, www/apex redirect mismatch, robots.txt AI bot blocking, sitemap presence) each with supporting evidence. Passing sites are queued for a free catalog check.
Example use cases
Pre-launch AI discoverability sanity check
“Before I launch my new SaaS site, can you run a quick AI crawler check on it to see if GPTBot and ClaudeBot will actually be able to crawl and index it? Just the fast $0.1 check — I want to know the score and top issues.”
Diagnosing why a site isn't showing in AI results
“My company blog never shows up when people ask AI assistants about our topic — can you run a quick AI visibility audit on blog.example.com to see what's blocking the crawlers?”
Checking a client site before SEO handoff
“I'm about to hand off this client site at acmecorp.com to their team — can you do a quick AI crawler check to see if GPTBot and PerplexityBot can see it and flag any critical issues like bad robots.txt rules or missing sitemaps?”
