2How many people visited

In plain words: These sites got fewer visits from Google than a year ago (-7%), and October 2026 was a better month than September 2026 (+5%). Ada Health, which takes 49.4% of all the visits, lost more visits on its own than the whole market lost in a year. Without it, visits would be up 56.0% on a year ago instead of down 6.6%.

Miles explains

Judge this line on the year, not the last dot: visits are 7% below a year ago, and 39% below the December 2024 high. One site winning or losing a ranking can swing a single month a lot.

3How many people went looking

People typed a site’s name into Google 7% less often than in October 2025 (-7%). That is the loyalty number: nobody types a name by accident.

US searches a month for the counted brand names, summed. Google Ads data via DataForSEO, to September 2026.

Miles explains

Name searches are the number I trust most. They are down 7%, and nobody types a site’s name by accident, so this shows fewer people coming back on purpose.

4Where the visitors live

About 31 of every 100 visits come from the United States. Outside the US I measure 7 countries one by one; the largest is India.

Miles explains

The US is the biggest single market, but only about 31 in every 100 visits. India alone is 58.2% of the countries measured outside it.

5The most-visited sites

Ada Health gets the most visits, Heartflow is the name people search for most, and no tracked site ranks on Google for “ai medical diagnosis”. The five most-visited sites take 96.9% of all visits.

By worldwide search visits

By US brand-name searches

Miles explains

The five most-visited sites take 96.9% of all visits. When one of them gains or loses a big ranking, the whole market total moves with it.

6Who grew and who shrank

The fastest grower in a year was Docus (+164%); the steepest fall was at Paige (-95%). Big swings are usually one site winning or losing one Google ranking.
