About this tool
The AISearch Global AI Crawler Checker looks at the two most common ways a site
accidentally blocks AI systems from reading it: a blanket Disallow: / rule in robots.txt
under User-agent: *, and a page-level noindex directive in the meta robots tag.
Either one can silently remove your business from consideration by ChatGPT, Perplexity, Gemini, and
other answer engines — even if the rest of your AEO signals are strong.
For a full technical AEO review beyond crawler access, see the AISearch Global AI Visibility Audit.
Frequently asked questions
What does the AI Crawler Checker actually check?
It fetches your site's robots.txt and checks whether it disallows all crawlers under a User-agent: * block, and it checks the page's meta robots tag for a noindex directive. These are the two most common ways a site accidentally blocks AI crawlers.
Why would AI crawlers be blocked?
Many sites use a blanket Disallow: / rule in robots.txt intended for staging environments, or a noindex tag left over from development, without realising it also blocks AI systems like GPTBot, ClaudeBot, and Google-Extended from reading and citing the page.
If AI crawlers are blocked, can I fix it myself?
Yes — remove the blanket disallow rule from robots.txt or the noindex meta tag from the page, then re-run this check to confirm. If you're unsure which crawlers to allow, AISearch Global's AI Visibility Audit reviews this as part of a full technical AEO check.
