What Is AI Visibility? How to Measure Your Brand

AI visibility, or AI brand visibility, is how often AI assistants name your brand and cite your website when people ask them for advice. It's the AI-search counterpart of ranking in Google, except that the result is a sentence in an answer rather than a position in a list.

What AI visibility means

When a buyer asks ChatGPT, Gemini, Claude, Perplexity or Google AI Mode what to buy, the answer usually names a few options and may link to a few sources. Your AI visibility is how often you're in those answers, how you're described and which pages are used. The work of improving it is usually called answer engine optimization.

The four things worth tracking

Named: how many answers mention your brand.
Cited: how many answers link to your website.
Who else: which competitors appear in the same answers.
Accuracy: whether what's said about your price and product is right.

Named and cited are different results. In our measurement of 869 answers, the brand named most in each category appeared in 92% of answers on average, but its own site was cited in only 27%.

What affects it

Providers don't publish how their answers are chosen, so anyone claiming a formula is guessing. These factors are ones you can check:

Crawler access. A page a crawler can't reach can't be retrieved. The AI crawler directory explains which bot does what.
Clear pages. A passage that answers the question directly is easier to use. See answer-ready passages.
Other websites. 83% of the links in our sample went somewhere other than the vendors we track. Which websites AI cites most has the list, and it differs for each AI.

How to measure it honestly

AI answers vary between runs, so one check proves little. Use a fixed set of real buyer questions, ask more than one AI, repeat on a schedule and keep the sample size beside every figure. Measuring AI visibility without false claims goes into the pitfalls.

You can start by hand with a spreadsheet. When you need repeated checks or reports for other people, compare the best AI visibility tools, and see how whole categories look on the AI recommendation leaderboards.

What it can't tell you

A high count doesn't prove AI drove a sale, because many readers never click. A low count on a few questions doesn't prove you're invisible everywhere. Treat AI visibility as evidence to act on, and give any comparison between brands the same questions, the same sources and the same dates.

Common questions

What is a good AI visibility score?

Be wary of single scores. A number with no sample size can hide everything that matters. Named in 12 of 60 answers tells you more than 20%, and much more than a score out of 100.

How is AI visibility different from SEO?

SEO measures where a page ranks in a list of results. AI visibility measures whether a written answer names your brand or links to your site. The two are related, but a page can rank well and still be missing from AI answers.

Can I check my AI visibility for free?

Yes. Write down ten questions your buyers ask, put them to two or three AI assistants, and record who is named and which sites are linked. It's slow but real, and it shows what the numbers mean before you pay for anything.
