Every month I measure Google visits to the 26 AI voice agent sites I track, and how often people search for them by name. In October 2026 they got about 666,707 visits, 49% fewer than a year ago and 5% fewer than in September 2026.

AI voice agent market: the key numbers for October 2026
Four numbers for October 2026. Visits mean visits from Google search to the tracked sites. Tap one for the detail below.
- The tracked sites got 666,707 visits from Google in October 2026, 49% fewer than a year ago and 5% fewer than in September 2026. PolyAI alone takes 57.5% of the visits, so the totals mostly follow it. Without it, visits would be down 57.4% on a year ago instead of down 49.2%. PolyAI lost more visits in October 2026 (50,094) than the whole market did (35,896); without it, visits to the other sites rose 5.3% on September 2026.
- Google Ads gives no search figure I can publish for “ai voice agents” this month. People searched the site names 54,710 times in the US in September 2026, 4% less often than in October 2025.
- 1 tracked site is on Google’s first page for “ai voice agents”; the highest is Retell AI at position 1. PolyAI is the most-visited site.
- 24.1% of visits came from the US (28.4% a year ago), then India, Canada and United Kingdom. The five most-visited sites took 90.9% of all visits.
1How many visits
In plain words: These sites got fewer visits from Google than a year ago (-49%), and October 2026 was a weaker month than September 2026 (-5%). PolyAI alone takes 57.5% of the visits, so the totals mostly follow it. Without it, visits would be down 57.4% on a year ago instead of down 49.2%. PolyAI lost more visits in October 2026 (50,094) than the whole market did (35,896); without it, visits to the other sites rose 5.3% on September 2026.
- Visits, October 2026

Miles explains
Judge this line on the year, not the last dot: visits are 49% below a year ago, and 61% below the December 2025 high. One site winning or losing a ranking can swing a single month a lot.
2How many people went looking
People typed a site’s name into Google 4% less often than in October 2025 (-4%). That is the loyalty number, because nobody types a name by accident.

Ordered by US searches for the brand name in September 2026. A measured order, not a ranking.
Miles explains
Name searches are the number I trust most. They are down 4%, and nobody types a site’s name by accident, so this shows fewer people coming back on purpose.
