AI Visibility Checker
Inspect crawl directives, structured data, public entity search matches and page structure. This technical diagnostic uses our own heuristics; it does not query live AI answers or measure retrieval, recommendations or citations.
Bot roles differ: OAI-SearchBot supports ChatGPT search, while GPTBot concerns model training. PerplexityBot supports Perplexity search. Googlebot controls Google Search crawling, including AI features; Google-Extended covers some other Google uses.
Allowing a bot in robots.txt does not prove that firewalls permit it or that the page will be selected. User-requested fetchers also have different rules. Neither llms.txt nor FAQ markup is required for Google AI features.
