About this tool

AI search engines need the same technical foundation as Google — plus llms.txt and open access for AI crawlers. See how visible your site is to ChatGPT, Claude, Perplexity, and Google AI in one report.

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

  • llms.txt presence and structure

Best practices

Recommendations from official docs

Allow OAI-SearchBot first

ChatGPT search requires OAI-SearchBot access. Without it, your pages will not appear in ChatGPT search answers with 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.
