AI CRAWLER ACCESS CHECKER

AI crawler access checker

Enter any URL. We fetch the site's robots.txt and test whether 10 major AI bots — GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and more — can crawl it. Blocked AI bots mean missed citations in ChatGPT, Perplexity, and Claude answers.

How it works

How does this tool work?

  • Enter a URL. The tool fetches robots.txt from the root domain server-side (no CORS issues).
  • The parser applies user-agent matching and longest-path specificity — the same logic crawlers use.
  • Results show allowed or blocked status for each bot with the matching rule line number.

FAQ

Questions people ask before using this tool.

Which AI crawlers does this tool check?

GPTBot and ChatGPT-User (OpenAI), ClaudeBot and Claude-User (Anthropic), PerplexityBot (Perplexity), Google-Extended and Gemini-Google-Bot (Google), Applebot-Extended (Apple), CCBot (Common Crawl), and Meta-ExternalAgent (Meta) — 10 bots in total.

What does "blocked" mean for an AI crawler?

Blocked means the site's robots.txt contains a Disallow rule that matches the bot's user-agent token for the root path. The crawler should not fetch those pages. This reduces the site's AI-visibility score.

Should I allow all AI crawlers?

That depends on your goals. If you want your content cited by ChatGPT, Perplexity, or Claude, you should allow their crawlers. If you want to block AI training but allow AI search retrieval, you can Disallow GPTBot (training) but Allow ChatGPT-User (retrieval), for example.

Does allowing AI crawlers guarantee citation in AI answers?

No. Allowing access removes the most disqualifying signal, but citation also depends on content quality, structured data, answer-oriented headings, and llms.txt guidance. The full audit checks all five GEO signals.

Why does the tool check the root path (/)?

Robots.txt rules cascade: a Disallow: / blocks the entire site. Checking the root first tells you if any bot is completely locked out. Use the full robots.txt tester to test specific paths like /blog/ or /tools/.
