Every month I add up the Google visits to the 38 AI agent builder sites I track (DataForSEO estimates) and how often people in the US search for them by name (Google Ads). In October 2026 they got about 3.2 million visits. n8n gained more visits in October 2026 (405,281) than the whole market did (233,276); without it, visits to the other sites fell 7.9% on September 2026.
The total hides very different stories: one site grew 1807% in a year while another lost 88% of its visits. See who grew and who shrank, the visits month by month and the name searches, plus what I expect for November 2026.

Miles explains
Visits are lower than a year ago, but the fall looks like it has stopped: October 2026 was up on September 2026. Name searches rose (+7344%) and Google Trends interest in the term held about level (+4%), so the drop looks like a few big sites losing Google rankings, not people losing interest.
2.Are people searching for AI agent builder sites by name?
Up 7344% on a year ago; 198K name searches a month in the US
Yes, more than before. People in the US searched Google for the names of the counted AI agent builder sites 198,000 times in September 2026, 7344% more searches than a year earlier. Someone who searches a site’s name already knows it, so this is the clearest sign of people coming back on purpose.

Name searches are up while visits are down. People still want these sites; what fell was Google rankings, not interest.
