Shrinking, but visits without Mayo Clinic Symptom Checker are up 316% on a year ago.

Over two years, visits went from 70M in November 2024 to a high of 111M in January 2025, fell to 76M in April 2025, and recovered to 89M in October 2026. Much of the year’s change is one site, Mayo Clinic Symptom Checker, which is why I also look at the market without it.

Miles explains

I only call a market growing when visits and name searches agree. Here visits are up and name searches are down, so they don’t agree yet.

“ai symptom checker” is searched about 2,900 times a month worldwide, 55% of it in the US.

Google Trends barely registered “ai symptom checker” until July 2024; interest then climbed to its peak in May 2026. Americans make 55% of the searches but only 32.6% of the visits, because the big sites also draw heavily from India, Canada and United Kingdom.

Miles explains

Google Trends shows direction, not volume. Interest is lower than a year ago, and I only trust that when the visits move the same way.

More visits than a year ago, but fewer people searching by name, and the next six months look flat.

The fastest growers over the year, Ubie and Mayo Clinic Symptom Checker, grew fastest, mostly from a smaller base. The losers, led by Ada, lost ground (-34%).

Isabel Symptom Checker -17%

Miles explains

Huge percentages like Ubie’s +1841% usually mean one site won a big Google ranking from a small start. I watch whether it holds the next month.

I expect November 2026 to be about the same as October 2026, and the next six months to look flat.

The forecast carries the level of recent months forward, not the trend line, because that version missed least when tested on past months.

Expected in November 2026

87,346,114 visits

Likely range

79M to 95M

Expected in May 2027

Miles explains

Read the range, not the single number: tested on the last 6 months, my method landed inside its range 5 times.

Mayo Clinic Symptom Checker alone has 96% of all visits. That’s a big lead, but one Google update can close it fast.
