AI Search Checker — ChatGPT, Claude, Perplexity, Google

An AI search checker tests whether ChatGPT, Claude, Perplexity, and Google can technically fetch you — robots.txt, llms.txt, and indexability. It does not track citations inside those engines. Run one report instead of checking each bot separately.

About this tool

An AI search checker tests whether ChatGPT, Claude, Perplexity, and Google can technically fetch you — robots.txt, llms.txt, and indexability. It does not track citations inside those engines. Run one report instead of checking each bot separately.

Measure AI search visibility across ChatGPT, Claude, Perplexity, and Google AI crawlers — bot access, llms.txt, and machine-readable content.

What we check

In your free report

  • OAI-SearchBot and GPTBot robots.txt access
  • llms.txt presence and structure

Best practices

Recommendations from official docs

Allow OAI-SearchBot first

ChatGPT search uses OAI-SearchBot to fetch pages for citations. Allowing it in robots.txt is a core eligibility step — without crawl access, your pages are much less likely to appear in ChatGPT search answers. Access alone does not guarantee citations.

Publish llms.txt as your AI map

llms.txt gives ChatGPT and other LLMs a curated index of your best pages — faster than inferring structure from HTML alone.

Serve key content in initial HTML

Bots often fetch without JavaScript. Critical product and pricing text must appear in server-rendered HTML, not only after client-side JS runs.

Track utm_source=chatgpt.com

OpenAI documents that ChatGPT search links include utm_source=chatgpt.com. Add this as a custom channel in analytics to measure AI referral traffic.

How to fix

Step-by-step action plan

  1. 1 Allow OAI-SearchBot in robots.txt on all public pages you want cited.
  2. 2 Create llms.txt with your top product, docs, and pricing pages.
  3. 3 Fix noindex tags and HTTP errors on high-value landing pages.
  4. 4 Improve title and meta description clarity — AI snippets reuse this text.
  5. 5 Run a full-site audit to find weak pages before ChatGPT and Google do.
