Every month I add up the Google visits to the 20 AI marketing automation sites I track (DataForSEO estimates) and how often people in the US search for them by name (Google Ads). In September 2026 they got about 5.8 million visits. Much of the year’s change is one site, Brevo; without it, visits are down 27% on a year ago.
The total hides very different stories: one site grew 449% in a year while another lost 86% of its visits. See who grew and who shrank, the visits month by month and the name searches, plus what I expect for October 2026.

Miles explains
More visits than a year ago means new people are still finding AI marketing automation sites through Google. Most of that growth is one site, Brevo; without it, visits are down 27% on a year ago.
2.Are people searching for AI marketing automation sites by name?
Down 16% on October 2025; 799K name searches a month in the US
Fewer than before. People in the US searched Google for the names of the counted AI marketing automation sites 799,160 times in September 2026, 16% fewer searches than in October 2025. Someone who searches a site’s name already knows it, so this is the clearest sign of people coming back on purpose. The term “ai marketing automation” itself gets about 480 US searches a month (Google Ads, 12-month average).

Miles explains
Name searches are down, so fewer people are coming back on purpose. Better Google rankings will not fix that.
