AI visibility

Glossary

AI visibility

Whether AI engines name a company when buyers ask about its market, and how often. It is where AI authority starts: a company the engines do not name cannot be recommended.

What it tells a buyer or a marketer

Most buyers describe a need before they know a name. When they put that need to an AI engine, the answer names a handful of companies. AI visibility is whether a company is among them, and how often, across the engines buyers use and the questions they ask.

For a marketer, it is the first thing to know, because nothing else follows without it: a company the engines do not name cannot be recommended, compared, or chosen from the answer. It is also the easiest to misread. An AI answer changes from one asking to the next, and from one engine to another, so one question asked once says little.

How it relates to AI authority

AI visibility is where AI authority starts. AI authority asks three things in turn: whether the engines name a company, whether they recommend it, and whether they describe it accurately. CRISP™ reads AI visibility mainly through Presence, how often the engines name a company when buyers name nobody, and Consensus, whether every engine does.

The AI Authority Index™ publishes both for every company on its Leaderboard, market by market, so a company can see its visibility beside its competitors', measured the same way.

How to check it, and what moves it

To check it, ask the questions your buyers ask, without your name in them, on every engine they use, more than once, and count how often you are named against your competitors. The free AI Authority Check™ does that for a company's market, across every engine it measures. AI visibility moves when the engines have more to read about the company in the places they look, which means the sources they cite for the market as much as the company's own site.
