Do AI search engines read your website?

ChatGPT, Claude, Perplexity and Gemini send crawlers to read websites. A single line in your robots.txt can lock them out, making you invisible in AI answers. Check in 10 seconds which AI search engines are allowed to read your site.

Why this matters

More and more people no longer search on Google, but ask their question directly to ChatGPT, Perplexity or Gemini. Those tools can only recommend you if their crawlers are allowed to read your website. Many sites block those crawlers, often by accident, via a single line in their robots.txt.

What this tool checks

We fetch your robots.txt and look, per AI search engine, at whether the corresponding crawler (such as GPTBot for ChatGPT, ClaudeBot for Claude or Google-Extended for Gemini) gets access or is blocked. A block means that AI cannot read your content and therefore cannot cite you.

And if I am blocked?

No panic. Often you can fix it by adjusting a few lines in your robots.txt. If you want to become structurally more discoverable in AI search engines, take a look at our AI search optimization (GEO).

Which firms does ChatGPT name in your city and industry?

Ask ChatGPT for "the best accountant in Brussels" or "a good installer in Antwerp" and you get a short list of names. Whether your business is on it depends on three steps. This check covers the first one.

Can AI read your site? If you block OAI-SearchBot, ChatGPT will not show your site in its search answers, as OpenAI's documentation states. That is what you test above.
Is your page citable? A clear service page per city or region, your name, address and industry stated consistently, and answers in short paragraphs. You test that with the GEO checker.
Are you mentioned elsewhere? AI assistants lean on what others write about you: reviews, industry directories, local media and comparison lists. You measure that by asking the questions your customers ask, as we explain in measuring AI visibility without tools.

Want to know which competitors ChatGPT recommends for your industry and region today, and what it takes to get on that list yourself? Read how to get recommended by ChatGPT or see our GEO approach.

Frequently asked questions about AI visibility

Does this tool show which firms ChatGPT recommends in my city?

No, this check tests whether AI crawlers may read your site. That is the precondition for ever being recommended. To see which firms ChatGPT names, ask the question your customers ask, for example the best provider in your industry and city, and track the answers for a few weeks.

Why does ChatGPT name my competitor and not me?

Usually because that competitor is mentioned more often and more clearly on other sites, such as review platforms, industry directories and local media, and because its own site says plainly what it does and where. A blocked crawler or a site without clear service and location pages plays a part too.

Which crawler should I allow for ChatGPT?

For ChatGPT's search answers it is OAI-SearchBot. OpenAI uses GPTBot to train its models; you can allow or block it separately. ChatGPT-User fetches pages when a user asks for it.

How often does ChatGPT's answer change?

Answers vary by question, by wording and sometimes by session. Measure with a fixed set of questions at fixed moments, and look at trends rather than a single answer.
