AI crawler access checklist: verify the exact bot and exact page.
An AI crawler access audit should test the exact public URL and the documented user agent for each provider. Check robots.txt, HTTP status, authentication, canonical tags, rendered text, redirects, firewall logs and rate limits. A permissive robots file alone does not prove that a page is reachable, indexable or selected as an answer source.

The question this page answers
Check whether AI search crawlers can access a website
Which layers can block access?
A request can fail at DNS, CDN, firewall, robots rules, authentication, redirects, application rendering or canonicalization. Test from outside the logged-in browser because an owner session can hide the public failure.
Which providers should be checked separately?
Review current documentation for Google crawlers, OAI-SearchBot and PerplexityBot. Training, search and user-triggered agents can use different identifiers and controls, so avoid treating all AI traffic as one bot.
- Documented user agent
- Public status code
- Rendered text
- Server-log evidence
What does a successful check prove?
It proves that the tested path was accessible at that moment. It does not prove indexing or citation. Save the time, user agent, response and page hash so future failures can be distinguished from content changes.
Questions buyers ask next
Should every AI crawler be allowed?
That is a publisher decision. Separate search visibility goals from training preferences and use each provider's documented controls.
Can JavaScript prevent AI systems from reading a page?
It can when important content is unavailable in the initial or rendered response used by the crawler, so server-rendered public text is safer.
Does HTTP 200 mean a page is indexable?
No. Canonical, robots, content and provider policies can still affect discovery and selection.
