Each month I forecast Google visits to the AI symptom checker sites I track, then score myself when the real number lands. For November 2026 I expect about 87 million visits, about the same as in October 2026.

Below: how my last forecast did, the next six months and site by site.

Each row uses only data from before that month.

Miles explains

5 of 6 in range is honest, not perfect. The biggest miss was July 2026 (-13%), the kind of month when one big site jumps. That’s why the range is wide.

2What is the market doing now?

Visits are up on a year ago (+6%), and the last three months were lower than the three before. Name searches are down (-31% since October 2025). Recent months are getting weaker; the forecast expects November 2026 to be about the same as October 2026.

Green grew, red shrank. Source: DataForSEO.

Miles explains

Big green or red bars are usually one site winning or losing a Google ranking, not the whole market moving. What I watch is the last three months against the three before: -8%.

3Is November usually a big month or a quiet one?

No seasonal pattern is used in this forecast: the five-year Google Trends series for "ai symptom checker" has too many empty months (24 of 61, the last in February 2024) to read a seasonal pattern from.

On the calendar, November brings Black Friday and Cyber Monday and Thanksgiving (US). Once the Google Trends series for the term can be read month by month, this section scores each month against an average month and tests whether that helps the forecast.

4What to expect in November 2026

About 87M visits in November 2026, about the same as October 2026. The likely range is 79M to 95M.

5What to expect over the next six months

6What the forecast expects for the 5 most-visited sites

The forecast expects Symptomate (+5%) and Isabel Symptom Checker (+3%) to rise, and none to fall by more than 3%; the rest are within 3% of October 2026. Single sites are harder to forecast than the whole market, so their ranges are wider.

Together the 5 come to 87,129,999, inside the market forecast of 87,346,114 for every tracked site.

Miles explains

Symptomate has the biggest expected rise (+5%). Single sites are much harder to call than the whole market, so read these as direction, not promises.

7What could change the forecast

What could knock November 2026 off course:

  • A big site winning or losing a page-one position for “ai symptom checker”.
  • A Google update.
  • A site going offline.
  • A news story that spikes interest for a week and then fades.

None of these are in the numbers until they happen, which is why the range exists.
