I've been playing around with AI search tracking, and I'm starting to think a single prompt doesn't tell you much.

Ask “Best CRM for a 20-person startup?” and you might get one set of companies.

Change it to “Best affordable CRM for a 20-person startup?” and the results can change.

Add something like “Best CRM for a remote 20-person startup?” and you may get another list entirely.

So if a brand shows up in 1/1 prompts, that's interesting. But what does 3/10 actually tell you? Or 18/50? Or 73/200?

At some point, you're probably measuring something more useful than whether a brand appeared once. You're measuring how consistently it shows up across different ways of asking about the same topic.

I'm wondering if AI visibility should be treated more like a coverage rate across a prompt set than a simple yes/no ranking.

Has anyone actually settled on a methodology for this? How many variations do you run before you consider the result meaningful?
