Is your brand in it, or missing?

How we measure

Per industry, 50 questions the way customers ask them, without brand names. Each question goes to ChatGPT, Gemini, Google AI Mode and AI Overviews every three days, logged out, from the country measured, in its language.

Visibility = share of answers that name a brand. Answers to the same question are related; the 95% range accounts for that.

"Tied" means two brands' ranges overlap, so the difference may be chance. We only show a change from last week when the ranges don't overlap.
