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 (-11%), the kind of month when one big site jumps. That’s why the range is wide.
2What is the market doing now?
Visits are down on a year ago (-7%), and the last three months were lower than the three before. Name searches are down (-7% since October 2025). Recent months are getting weaker; the forecast expects November 2026 to be about the same as October 2026.

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: -5%.
3Is November usually a big month or a quiet one?
November is usually a bigger month than average (12% above) for searches for “ai medical diagnosis”. But the sites’ visits follow rankings more than the calendar, so the pattern is shown and not allowed to move the numbers.

- No: average miss 6.1% as chosen, 6.1% without the pattern, 14.5% always with it

Miles explains
I tested the calendar against the last months and it made the forecast worse (14.5% average miss with it, 6.1% without), so I show it but leave it out.

6What the forecast expects for the ten most-visited sites
The forecast expects Aidoc (+7%), Heartflow (+6%), Dr.Khan AI Medical Assistant (+12%), Alethea (+4%) and Lunit (+3%) to rise, and RapidAI (-52%) to fall; 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 ten come to 824,258, inside the market forecast of 832,440 for every tracked site.
Miles explains
Dr.Khan AI Medical Assistant has the biggest expected rise (+12%). 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 medical diagnosis”.
- 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.
