AI Visibility Check for ChatGPT & Co.

An AI visibility check is a one-time audit that shows whether and how your company appears in answers from AI assistants such as ChatGPT, Perplexity, Gemini and Google AI Overviews. It covers two layers: your presence in the answers themselves, and the technical conditions that allow those systems to read your content in the first place. What you end up with is a baseline you can measure later work against.

What the check measures

The basis is a prompt set, not one lucky question. We collect the phrasings buyers in your market actually use: vendor comparisons, problem questions, regional questions with a place name, price questions, alternatives to named competitors. That set runs repeatedly across several systems, and every run gets logged.

• Mentioned without a link, mentioned with a citation, absent: three different states with three different causes.
• Which domains get cited instead, from trade directories and industry media to forums and competitor blogs.
• Your share of mentions against the three to five vendors you meet most often in pitches.
• Differences between German and English prompts. In our own measurements, the assistants lean on English sources noticeably often, even for DACH topics.

Why a single test proves nothing

Language models do not answer deterministically. Ask the same question twice and you get different sources and sometimes different vendors. Anyone who asks once, fails to find themselves and calls that a finding has measured noise. So every prompt is repeated, with and without personalisation, and the results are read across all runs rather than judged one by one.

The technical layer

Content an assistant cannot fetch does not exist for that assistant. We check whether GPTBot, OAI-SearchBot, PerplexityBot and ClaudeBot are allowed in your robots.txt, whether a WAF or bot rule filters them out, and whether your pages stay readable without JavaScript execution. Blocking happens by accident more often than by decision, usually through a default CDN rule that drops unknown user agents. On top of that come the things that help the systems summarise you correctly: clear definition paragraphs, clean heading logic, JSON-LD, and company data that does not contradict itself across imprint, directories and your Google Business Profile.

Where the check stops

The check is diagnosis, not delivery. Ongoing work on entities, citability and monitoring belongs to our GEO service. And if you want the classic Google side of your visibility first, the free SEO check runs automatically, tests technical and on-page criteria and mails you the report. It does not replace the AI visibility check, because it says nothing about what ChatGPT tells people about you.

What you get

A document with the prompt set used, the logged answers per system, the source list, and a fix list sorted by impact and effort. Plus an assessment of what your team can handle in-house and what needs work on content and entities. If you keep going, the prompt set is already the measuring instrument for your next round.
