# 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.

## FAQ

### 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.
