Track your AI visibility.
Across every assistant.

Measuring something that gives a different answer every time

Rank tracking assumes a stable, orderable result you can record as a number. AI visibility breaks that assumption completely, and any tool that reports it as a tidy position is hiding the problem rather than solving it.

Why the measurement is genuinely hard

Responses are non-deterministic: the same prompt can produce different sources on consecutive runs. There is no ranked list, only a passage that either mentions you or does not. Phrasing changes everything, since "best SEO tool" and "what SEO tool should a small team use" retrieve differently. Models are updated silently, so a shift can come from them rather than from you. And each engine behaves differently, with some retrieving live from the web and others leaning on training data with a cutoff.

What is worth measuring anyway

Given that, useful measurement is statistical rather than absolute.

Mention rate. Across a fixed set of prompts run repeatedly, how often are you named at all? This is the base metric, and it only means anything if the prompt set stays constant.

Citation rate. How often are you named with a link, as opposed to mentioned in passing? Being the linked source is a materially better outcome.

Share of voice. Of the brands named for your prompts, what proportion are you? This is more robust than your own rate alone, because it partly cancels out model-wide changes in how many sources get cited.

Sentiment and accuracy. Being described wrongly is worse than not being described. This is the check that catches the reputational problems, and it is the one most easily forgotten.

Reading the results honestly

Run the same prompts on a schedule and treat individual results as samples rather than facts. A single absence proves nothing. A mention rate that falls from 60% to 20% over a month across several engines is a real signal. Anyone promising precise, repeatable AI rankings is describing something that does not exist yet.

How UtilitySEO handles this

We track brand visibility across ChatGPT, Claude, Perplexity and Grok over time rather than reporting a single position, so you are looking at a trend across engines instead of one sampled answer.
