ChatGPT SearchBot Checker

Check whether a site is technically ready for ChatGPT Search: OAI-SearchBot access, robots.txt policy, indexability, readable HTML and sitemap discovery.

When to use this

Use this checklist when a page should be eligible for ChatGPT Search but you are not sure whether the public source can be crawled and understood.

What to allow

OpenAI documents OAI-SearchBot as the crawler for ChatGPT search features. GPTBot is a separate training-oriented crawler, and ChatGPT-User is user-triggered rather than automatic search crawling.

  • Allow OAI-SearchBot for pages you want surfaced in ChatGPT search-style answers.
  • Do not assume allowing GPTBot is required for search visibility.
  • Verify that edge security allows the published OpenAI crawler IP ranges when you enforce bot rules.
User-agent: OAI-SearchBot
Allow: /

User-agent: GPTBot
Disallow: /

Sitemap: https://example.com/sitemap.xml

What to inspect

A robots.txt allow rule is not enough if the page returns a 403 to crawler-like traffic, hides the real content behind JavaScript, or marks the canonical page noindex.

  • HTTP 200 on the final canonical URL
  • No accidental noindex, nosnippet or restrictive X-Robots-Tag on public pages
  • Enough product, documentation or answer text in initial HTML
  • A sitemap that includes the public URLs you want discovered

Checklist

Fetch /robots.txt and confirm OAI-SearchBot has an explicit allow or inherits a non-blocking wildcard rule.

Fetch the target URL with a crawler user agent and confirm it does not hit a WAF challenge.

View source and confirm the answer-critical text appears before JavaScript runs.

Check canonical, meta robots and X-Robots-Tag headers.

Submit the updated sitemap in Search Console and request indexing for the highest-value URLs.

FAQ

What does ChatGPT SearchBot Checker check first?

Fetch /robots.txt and confirm OAI-SearchBot has an explicit allow or inherits a non-blocking wildcard rule.

Does this guarantee ranking or inclusion in AI answers?

No. It checks public technical signals that can make a page easier to crawl, parse and cite, but no tool can guarantee ranking, indexing or citation in ChatGPT, Claude, Perplexity or Google.

Should I fix robots.txt, llms.txt or page rendering first?

Fix public reachability, indexability and readable initial HTML first. robots.txt should express crawler policy, and llms.txt is optional supporting documentation rather than a replacement for normal search fundamentals.
