AI visibility

How often, how favorably and how prominently a brand appears in answers generated by AI systems such as ChatGPT, Gemini and Perplexity.

What it measures

AI visibility is not one number but a set of related signals: whether a brand is mentioned at all, whether it is actively recommended, where it appears relative to competitors, whether the AI cites the brand’s own website, and whether that holds across more than one provider.

Why it differs from search rankings

A traditional search result page has a fixed set of ten blue links you can check on demand. An AI answer is generated fresh for each question and can vary between runs, providers and phrasing. There is no single "position one" to track — visibility has to be estimated by sampling representative questions and observing patterns.

How to measure it without guessing

The only reliable approach is to ask the same kind of commercially relevant questions a real buyer would ask, across more than one provider, and record what actually comes back — not what a single spot-check happened to show.
