Monthly estimate, refreshed at the start of each month. The latest month is highlighted.
Estimates can move a lot month to month: one rank change in a single high-volume category can shift a site's total noticeably.

How often ChatGPT places this site at each position across its prompt topics.
Sites that come up for the same prompts as Mayoclinic.org, ranked by how many topics they share.
ChatGPT doesn't publish prompt data. We measure real demand for each commercial topic from Google search volume, scale it to ChatGPT's user base (about 1 ChatGPT user for every 8 Google searchers), and run each topic through ChatGPT 5 times to record which sites it recommends and in what order. A click-through-by-rank curve splits each topic's demand across the recommended sites. Every figure is a modeled estimate, not measured analytics. Full methodology →
