- Visits, last six months

- Name searches vs October 2025
- -6.6%
Every month I add up the Google visits to the 13 AI medical diagnosis tool sites I track (DataForSEO estimates) and how often people in the US search for them by name (Google Ads). In October 2026 they got about 839,660 visits. Much of the year’s change is one site, Ada Health; without it, visits are up 56% on a year ago.
The total hides very different stories: one site grew 164% in a year while another lost 95% of its visits. See who grew and who shrank, the visits month by month and the name searches, plus what I expect for November 2026.

Miles explains
Visits are lower than a year ago, but the fall looks like it has stopped: October 2026 was up on September 2026. Name searches (-7%) and Google Trends interest in the term (-65%) fell too, so people are less interested, not just finding these sites less often.
2.Are people searching for AI medical diagnosis tool sites by name?
Down 7% on October 2025; 33.0K name searches a month in the US
Fewer than before. People in the US searched Google for the names of the counted AI medical diagnosis tool sites 33,000 times in September 2026, 7% fewer searches than in October 2025. Someone who searches a site’s name already knows it, so this is the clearest sign of people coming back on purpose. The term “ai medical diagnosis” itself gets about 2,900 US searches a month (Google Ads, 12-month average).

Miles explains
Name searches are down, so fewer people are coming back on purpose. Better Google rankings will not fix that.
