Shrinking, but visits are up 33% over the last six months.

Over two years, visits went from 11M in October 2024 to a high of 11M in October 2024, fell to 3.9M in May 2026, and recovered to 5.8M in September 2026. Much of the year’s change is one site, Brevo, which is why I also look at the market without it.

Miles explains

I only call a market growing when visits and name searches agree. Here visits are down and name searches are down, so they agree.

“ai marketing automation” is searched about 1,600 times a month worldwide, 30% of it in the US.

Google Trends barely registered “ai marketing automation” until June 2025; interest then climbed to its peak in May 2026. Americans make 30% of the searches but only 16.4% of the visits, because the big sites also draw heavily from India, Canada and Brazil.

Miles explains

Google Trends shows direction, not volume. Interest is about the same than a year ago, and I only trust that when the visits move the same way.

More visits than a year ago only because of Brevo, but fewer people searching by name, and the next six months look about flat.

The fastest growers over the year, Brevo, Klaviyo and Customer.io, grew fastest, mostly from a smaller base. The losers, led by Drip, lost most of their search visits (-86%).

Miles explains

Huge percentages like Brevo’s +449% usually mean one site won a big Google ranking from a small start. I watch whether it holds the next month.

I expect October 2026 to be about the same as September 2026, and the next six months to look up.

The forecast carries the level of recent months forward, not the trend line, because that version missed least when tested on past months. October is usually a busier month than average for searches, but the calendar did not improve the forecast, so it is left out.

Read the range, not the single number: tested on the last 6 months, my method landed inside its range 4 times.

The most visited is Brevo, with 3 million visits a month, 52% of all visits.

Brevo and Mailchimp together hold 79% of all visits. Below the top five the market is long and thin: the other 15 sites share 5.7%.

Miles explains

Brevo alone has 52% of all visits. That’s a big lead, but one Google update can close it fast.
