AI visibility checker.

The AI visibility check finds out whether AI search engines like ChatGPT, Claude, Perplexity or Google AI Overviews can read and cite your website. It checks AI crawler access in robots.txt, the llms.txt file, structured data about your company, an answer right under the heading, questions and answers, and text structure. It also drafts an llms.txt file.

We check whether AI search engines (ChatGPT, Claude, Perplexity, Google AI) can read and cite you: crawler access, llms.txt, structured data and text structure. We also draft an llms.txt.

How to use it

Step01

Enter the address
Ideally the home page or the page of your main service.
Step02

Go through the results
Most important: AI search engines must have access, and the text must answer right at the start.
Step03

Download llms.txt
Edit the draft and upload it to your site's root as /llms.txt.

Five things that decide AI visibility

Access. If robots.txt blocks AI search engines, they can’t cite you. Fix it with the robots.txt generator.
An answer at the top. A short paragraph that directly answers the page’s main question.
The entity. Structured data about the company (Organization, LocalBusiness) and linked profiles, so AI knows who you are. Use the JSON-LD generator.
Facts in structure. Lists, tables, questions and answers, data with a cited source.
Freshness. A last-updated date and regular content updates.

How to tell if it works

Ask ChatGPT, Perplexity or Gemini about your field and city, such as “AI agency Prague” or “café with breakfast Prague 4”, and see who they cite. Do it regularly, say monthly, because results change. In analytics you’ll also see visits from chatgpt.com or perplexity.ai as a source.

FAQ04

Questions people ask

01What is GEO?

Generative Engine Optimization: making AI assistants cite and recommend you in their answers. It rests on the same foundations as SEO: accessibility, clear and factually accurate content, structured data and trust.

02Does llms.txt work?

Honestly, it isn't confirmed yet. The file was proposed by the llmstxt.org initiative and no major AI search engine has publicly confirmed using it. But it takes minutes to create and breaks nothing, so we recommend it as a cheap bet.

03Should I let training crawlers in too?

That's your call. Training crawlers (GPTBot, ClaudeBot, Google-Extended) collect data for models. Search crawlers (OAI-SearchBot, Claude-SearchBot, PerplexityBot) collect data for answers with links. The check scores only search crawlers and just shows the training ones.

04Why does an answer at the top matter?

AI search engines pick short passages from a page that directly answer the question. A 40–60 word paragraph under the main heading saying who you are and what you offer is the easiest way into an answer. Every page on this site starts with one.
