Miles explains
3 of 6 in range is honest, not perfect. The biggest miss was September 2026 (-20%), 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 (-24%), and the last three months were lower than the three before. Name searches are about level (-3% since October 2025). Recent months are getting weaker, yet the forecast expects October 2026 to be up on September 2026, because it averages September 2026 with the months before it, which were higher. The backtest below shows how often this method calls the direction right.
- Visits, September 2026
- 602,538 (-18.2% on the month before, -23.9% on a year ago)
- Last 3 months vs the 3 before
- -33.9%

- 34/100 (0% on a year ago)
- 12-month trend
- -2.7% a month; the forecast carries the level of recent months, not the slope

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: -34%.
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 voice agents" has too many empty months (36 of 60, the last in September 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

5What to expect over the next six months
By April 2027 the forecast expects about 624,410 visits a month, +4% on the 602,538 of September 2026, so the next six months look flat, after a step up from September 2026.

6What the forecast expects for the 9 most-visited sites
The forecast expects PolyAI (+5%), Retell AI (+4%) and SquadStack (+15%) to rise, and Vapi (-6%), Replicant (-4%) and Regal (-6%) 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.

|---|---|---|---|---|
 PolyAI | 433,416 | 453,871 | 349K to 559K | +4.7% |

Together the 9 come to 623,799, inside the market forecast of 624,410 for every tracked site.
Miles explains
SquadStack has the biggest expected rise (+15%). 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 voice agents”.
- 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.
