AI visibility checker: can ChatGPT read your site?

The check reads your public signals in 30 seconds. It tells you, bot by bot, who is allowed to read you.

100% free · no signup · 0 cookies · result shareable with a link

Then Snorklee counts the hits every day from €8/month ex. VAT. 14-day free trial, no card.

The check only reads what your site already publishes, with no login.

Six checks. No guesswork.

The check does not predict your place in AI answers. It looks at what can stop them from reading you.

  • AI bot accessYour robots.txt, read bot by bot: GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Bingbot, MistralAI.
  • llms.txt filePresent or missing. That convention can help; it guarantees no citation.
  • IndexabilityThe directives that block: noindex, robots meta, X-Robots-Tag, noai.
  • Structured dataThe schema.org markup that tells a machine what the page is about.
  • Content readable without JavaScriptMany bots do not run JavaScript. If everything loads afterwards, they see nothing.
  • SitemapA sitemap.xml, or its link in robots.txt, so your pages get found.

A new kind of diagnostic

A classic audit hands you a grade, then leaves you guessing. This check is the start of a measurement.

  • An audit grades your setup.Snorklee counts what AIs actually do on your site: which bots read which pages, and how many times.
  • Other tools ask the AIs questions.Snorklee simulates nothing: it reads the traffic your server receives, and estimates no percentage.
  • A one-off report ages by the next day.Snorklee measures every day, and compares each period with the previous one.

And all of that — web analytics included — from €8/month ex. VAT, 14-day trial, no card. This check stays free.

After the check: €8 a month, and you measure.

Frequently asked questions

What exactly does this check look at?
Six public signals on your site: robots.txt, llms.txt, indexability, sitemap, structured data and content readable without JavaScript.
How do I let ChatGPT read my site?
Check that your robots.txt blocks neither GPTBot nor ChatGPT-User. The check tells you which ones are allowed, bot by bot.
How do I block GPTBot?
Add "User-agent: GPTBot" then "Disallow: /" to your robots.txt. Careful: ChatGPT-User is a different bot — the one that brings you visitors.
Do I need an llms.txt file?
It is an emerging convention, not a standard. It can help; it guarantees no citation.
Does this check guarantee ChatGPT will cite me?
No. It checks that AIs can technically read your pages. What they do next depends on nobody but them.
How do I find out who really reads my site?
This check is a snapshot. Snorklee counts AI bot hits and the visitors they send you every day, from €8/month ex. VAT.
Is the check really free?
Yes: no account, no card, no cookie. The result is shareable with a link.

The check says whether AIs can read you. Snorklee says whether they do.

€8/month ex. VAT: 200,000 pageviews, 10 sites, web analytics included. 14-day free trial, no card.
