Each month I forecast Google visits to the AI writing assistant sites I track, then score myself when the real number lands. For November 2026 I expect about 264 million visits, about the same as in October 2026.
Below: how my last forecast did, the next six months and site by site.

Miles explains
3 of 6 in range is honest, not perfect. The biggest miss was October 2026 (-21%), 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 (-32%), and the last three months were lower than the three before. Name searches are down (-29% 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: -25%.
3Is November usually a big month or a quiet one?
November is usually a quieter month than average (11% below) for searches for “ai writing assistant”. But the sites’ visits follow rankings more than the calendar, so the pattern is shown and not allowed to move the numbers.

Miles explains
I tested the calendar against the last months and it made the forecast worse (12% average miss with it, 8.7% without), so I show it but leave it out.
4What to expect in November 2026

6What the forecast expects for the ten most-visited sites
The forecast expects GPTZero (+7%) to rise, and Turnitin (-14%) 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.

Turnitin is held to its own range from October 2026. Together the ten come to 259,902,678, inside the market forecast of 263,881,115 for every tracked site.
Miles explains
GPTZero has the biggest expected rise (+7%). 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 writing assistant”.
- 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.
