Google monthly search volume: Google Ads, worldwide, read 10 Nov 2026. Third-party estimated keyword demand is a separate source, many times apart in size, so it has its own axis at the right: read the two lines for their trends.
Each site's latest estimate of its visits from this keyword; “As ads”: those visits at its cost per click, what they would cost to buy; DR: Ahrefs Domain Rating; linking sites: sites linking to it (third-party link index).

Listed A–Z. A top search keyword is one of the searches that bring a site the most visitors, by estimate. It is not a position in Google, and the order here is not a ranking. Visits (est.): the traffic estimate's own figure for the keyword on that site, which behaves like visits a month, not an amount of money (2026-09-29: it had been shown in dollars). This page is kept out of search results until 15 sites share the keyword.
