AI Visibility
Quick answer
AI visibility is how often, how accurately and how favorably a brand shows up when someone asks an AI answer engine a question related to buying a product in its category. It covers whether the brand is named at all, how it is described, and which competitors appear alongside it, across each engine checked.
Why it matters
A brand can rank well on Google and still be effectively invisible inside an AI-generated answer, because the two systems draw on different inputs and reward different things. As more buyers start a purchase decision by asking an AI assistant directly, a brand with no visibility there is losing consideration at the exact moment a prospect is deciding who to shortlist, with no equivalent to a search-ranking report to show it happening. Because the gap does not show up in ordinary web analytics, a brand can lose this kind of consideration for a long stretch before anyone on the team notices.
How to measure it
Run a fixed set of buying questions through each AI engine a brand cares about on a repeating schedule, and record whether the brand is mentioned, in what position relative to competitors, and what the answer says about it. MarketHQ runs this weekly across six engines, so a single bad answer on one day is less likely to be mistaken for a trend, and a real shift after a content change is visible instead of anecdotal. Keeping the same question wording across every run also matters, since a reworded question can change the answer regardless of anything else changing.
Example
A note-taking app ranks on the first page of Google for its main category term, but a weekly AI-visibility check shows it is never mentioned when the same category question is asked across any of the engines tracked. The team treats that gap as a separate problem from search ranking, not a symptom of it, and starts by checking which third-party pages the engines do cite for the category instead. A few weeks after publishing a page that directly addresses the same question, one of the engines begins naming the brand for the first time.
Frequently asked questions
Is AI visibility the same as SEO?
No. SEO is about ranking in a search results page; AI visibility is about whether and how an AI engine's generated answer mentions the brand, which depends on different sources and can move independently of search rankings.
Which AI engines count toward AI visibility?
MarketHQ checks ChatGPT, Claude, Gemini, Perplexity, Grok and DeepSeek on a weekly schedule; other tools may define the set differently.
How quickly can AI visibility change?
It depends on the engine's own crawl and update schedule, which a brand cannot control directly; a weekly check is frequent enough to catch real movement without mistaking normal day-to-day variation for a trend.
Is a single AI answer enough to judge AI visibility?
No. The same question can get a slightly different answer on different days from the same engine, so a pattern across repeated checks is what actually shows a brand's standing, not any one answer.
