Each month I forecast Google visits to the AI agent builder sites I track, then score myself when the real number lands. For October 2026 I expect about 1.9 million visits, about the same as in September 2026.
Below: how my last forecast did, the next six months and site by site.

Miles explains
5 of 6 in range is honest, not perfect. The biggest miss was April 2026 (-30%), 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 (-27%), and the last three months were higher than the three before. Name searches are down (-31% since October 2025). Recent months are getting stronger; the forecast expects October 2026 to be about the same as September 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: +14%.
3Is October usually a big month or a quiet one?
No seasonal pattern is used in this forecast: the five-year Google Trends series for "ai agent builder" has too many empty months (30 of 60, the last in March 2024) to read a seasonal pattern from.
On the calendar, October brings the start of the fourth quarter and next year's budget planning. 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 October 2026
About 1.9M visits in October 2026, about the same as September 2026. The likely range is 1.8M to 2.1M.

5What to expect over the next six months

6What the forecast expects for the ten most-visited sites
The forecast expects Lindy (+6%) to rise, and Botpress (-4%), LangChain (-6%) and Relevance AI (-3%) to fall; the rest are within 3% of September 2026. Single sites are harder to forecast than the whole market, so their ranges are wider.

Together the ten come to 1,806,082, inside the market forecast of 1,921,511 for every tracked site.
Miles explains
Lindy has the biggest expected rise (+6%). 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 October 2026 off course:
- A big site winning or losing a page-one position for “ai agent builder”.
- 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.
