Short answer: AI visibility measures whether AI assistants (ChatGPT, Claude, Gemini, Perplexity) mention and recommend your company when someone asks them about what you sell. It shares SEO's goal, being found, but almost everything else changes: the format of the answer, the sources that carry weight and the way it's measured.
From ten links to a single answer
In a classic search engine, the user sees a list of results and decides which one to click. In an AI assistant, they get a written answer that usually includes a handful of options, often with an explanation of why each one fits. If you're not in that answer, you don't exist for that conversation: there is no second page.
This work goes by several names: GEO (Generative Engine Optimization), AEO (Answer Engine Optimization) or simply AI visibility. They all refer to the same thing.
What an AI assistant takes into account
There's no public formula, and each model works differently. What you can observe is where the information comes from:
- What the model learned during training. If your brand appears often and consistently on websites, in the press, in forums and in directories, the model is more likely to know it.
- What it finds when it searches in real time. ChatGPT, Claude, Gemini and Perplexity can search the web before answering. In that case, the pages they cite carry a lot of weight: comparison articles, industry directories, media outlets, reviews and your own website.
- How clear your content is. A website that explains directly what you do, who it's for, where and with what results is easier to summarize and to cite.
How it's similar to SEO and how it isn't
| Classic SEO | AI visibility | |
|---|---|---|
| Result | List of links | Written answer with a few options |
| What's measured | Position of a URL | Whether you're mentioned, where and how you're described |
| Sources that matter | Your website and its links | Your website and, above all, what others say about you |
| Stability | Fairly stable | Answers vary across questions, models and days |
Much of what works in SEO still helps: a fast, crawlable website with good content. But that alone isn't enough. If the industry comparisons that AI consults don't include you, it's unlikely to recommend you.
Why it has to be measured methodically
AI answers aren't fixed. The same question, asked twice, can give different results. That's why a screenshot proves nothing. To really know whether you show up, you need to:
- Ask the questions your customers would ask, not the ones you'd like them to ask.
- Repeat them several times and across several models.
- Calculate percentages with their margin of error.
- Repeat the measurement over time to see whether your changes have an effect.
That's how we measure at Visaeon. The full methodology is on our methodology page.
Where to start
- Check that your website lets AI crawlers in (we explain how in this robots.txt guide).
- Explain clearly on your website what you do, who it's for and where.
- Identify which pages AI cites when it talks about your industry and work on getting onto them.
- Ask real customers for reviews, legally (here's how).
- Measure before and after.
