What is AI search visibility?
AI search visibility is how often AI engines name, link to, or draw on your business when they answer questions in your category. It is measured by mentions, linked citations, and recommendations, not by a position in a list of links. It covers engines like ChatGPT, Perplexity, Google AI Overviews, and Microsoft Copilot.
- AI search visibility is about being named, linked, or recommended inside an answer, not about holding a position in a list of links.
- An engine can name your business without linking it, or link your page without recommending you, so each outcome is counted on its own.
- Google says its AI features use query fan-out, which means one question triggers several related searches.
- Bing's AI Performance report counts citations in Copilot and Bing's AI summaries, and Google's Search Console has a Generative AI performance report that counts impressions.
- Researchers introduced generative engine optimisation (GEO) in 2023 as a framework for improving visibility in these answers.
When someone asks an AI engine a question, it writes one answer and shows the sources behind it. AI search visibility is how often your business appears in that answer, either by name, as a linked source, or as a recommendation.
What does "visible" mean in an AI answer?
It means one of three things, and each is a different result. Your business can be named in the text, your page can be linked as a source, or the engine can recommend you.
- Named. The answer mentions your business. It may not link to you.
- Linked. Your page appears as a source. Perplexity says PerplexityBot is designed to surface and link websites in its search results [5], and Google says its AI features show clickable links to supporting web pages [1].
- Recommended. The answer tells the buyer to choose you.
Links and mentions are not the same thing. OpenAI says a site that blocks OAI-SearchBot will not be shown in ChatGPT search answers, though it can still appear as a navigational link [3]. Counting each outcome on its own keeps you from mistaking one for another.
Researchers also measure it by share. The GEO paper scores a source by how many of the response's sentences relate to its citation, and by a second score that weights sentences near the start of the response more heavily [4].
How is it different from ranking in search results?
A ranking is a position in a list of links. An AI answer is one written response built from several sources, so your business is either in it or it is not.
Google's ordinary results do have positions. Search Console reports average position as "a relative ranking of the position of your link on Google, where 1 is the topmost position" [7]. An AI answer has no list order like that, so keep the two measures apart.
Google's AI features use query fan-out, which its guide defines as "a set of concurrent, related queries generated by the model to request more information and fetch additional relevant search results" [1]. They show "prominent, clickable links to relevant web pages that support the information in the response" [1].
The GEO paper describes generative engines the same way. They retrieve relevant documents and generate a response grounded in those sources, with attribution [4].
To be eligible, a page must be indexed and eligible to be shown in Google Search with a snippet [1].
Which engines does it cover?
It covers any engine that answers a question in its own words and shows sources. The ones this page draws on are ChatGPT search [3], Perplexity [5], Google AI Overviews and AI Mode [1], and Microsoft Copilot [2].
Each engine has its own crawler and its own controls. Being visible in one does not mean being visible in the others.
What are GEO and AEO?
They are two names for the work of improving AI search visibility. The GEO paper, accepted to KDD 2024, introduced generative engine optimisation as a framework for helping content creators improve their visibility in generative engine responses [4]. Many practitioners use answer engine optimisation (AEO) for the same goal. The terms are used loosely, so check how a writer or vendor defines them.
How do you measure it?
Count mentions, linked citations, and recommendations for the questions your buyers ask. Bing gives you the most direct first-party report. Its AI Performance report covers Microsoft Copilot, AI-generated summaries in Bing, and select partner integrations. It reports total citations, average cited pages, grounding queries, and page-level citation activity [2].
Google has a Generative AI performance report in Search Console [1]. It shows impressions, pages, countries, devices, and dates, and it does not include clicks or queries [6]. Google also says no third-party tool has access to its internal ranking or AI systems [1]. The sources used here describe no equivalent report for ChatGPT or Perplexity. For those, you ask your buyer questions yourself, several times, and record what appears.
We asked 11 buyer questions, 3 times on each engine.
C8 check, October 2026. ChatGPT (chatgpt.com, logged out, model not shown), Perplexity (Perplexity API (sonar)), Gemini (Flash-Lite). Each prompt asked 3 times on each engine, logged out, one fresh session per run.
