AI Bot & Crawler Checker

Check robots permission and real server responses for GPTBot, ClaudeBot, PerplexityBot and more.

Run a deterministic technical check

The result comes from HTTP requests, parsers and maintained rules — no AI guessing, so it is reproducible.

The check runs against the site root, e.g. yourbrand.com

About this check

01

What does this tool check?

Four gates decide whether AI can read your site: robots.txt permission, whether the server actually lets the crawler UA through (WAFs often 403 GPTBot even when robots.txt allows it), how much content survives without JavaScript, and meta/header blocking directives.

02

How should I read the result?

We probe from our own servers, so we can only test UA-level blocking. Every probe ships with a normal-browser control request: if the control itself fails, verdicts show "inconclusive" — never a false "blocked". Google-Extended and Applebot-Extended are robots tokens only, so they are marked not probeable.

03

What should I do next?

If a crawler is blocked at the server level, fix it in your CDN/WAF bot settings — robots.txt cannot help there.

Access rules change without warning

robots.txt edits and CDN bot rules usually ship without anyone telling you. The DaleGEO workspace re-checks on a schedule and alerts you when a crawler starts getting blocked.
