Free AI crawlability checker for your site
AI Crawlability checks whether AI bots can reach and read your public site. A pass means the tested access signals allow a bot to fetch your page; a fail identifies the rule or technical signal to fix.
Free. Checks GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more.

How to structure pages so AI answer engines can extract and cite them: direct answers, question-led headings, scannable formatting, and FAQ and Article schema.
ReadWhat is AI crawlability?
AI crawlability is the ability of AI answer engines — ChatGPT, Perplexity, Google AI Overviews and Claude — to reach, render, parse and cite a website's content. It overlaps with classic SEO crawlability but is not the same: AI engines use distinct crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) and most do not execute JavaScript, so a site that ranks in Google can still be invisible to them.
How do you make a site visible to AI answer engines?
Allow the AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) in robots.txt, serve your content as server-rendered HTML so it exists without JavaScript, add Article and FAQPage schema, and put the direct answer first in every section. Access enables eligibility; structure decides whether engines like Google AI Overviews actually quote you. The free checker tests the access layer; the complete guide covers the full checklist.
Frequently asked questions
Is being crawlable enough to get cited by AI?
No. Crawlability is necessary but not sufficient. Allowing a bot only makes you eligible — clarity, authority, source-grounding and a direct-answer structure decide whether an engine actually quotes you. The checker reports access; the guides cover extractability.
Which AI crawlers should I allow?
At minimum the retrieval crawlers that power live answers: GPTBot and OAI-SearchBot (ChatGPT), PerplexityBot, ClaudeBot, and Google-Extended (Google AI). Blocking these removes you from those engines' answers. Training-only crawlers like CCBot are a separate, optional policy decision.
· AI Crawlability Editorial
AI Crawlability Editorial maintains this guide and checker. Our method is to inspect publicly available robots.txt rules, page HTML, response headers, and discovery files for the signals described on this page; results describe access, not a promise of citation or ranking.
Crawlability is necessary but not sufficient for citation. We won't promise guaranteed rankings — we tell you exactly what AI engines can read today, and how to make your content the clearest answer.
