Google Ads put US searches for "ai agent builder" more than five times higher in August 2026 than in the months before, while Google Trends interest in the US in August 2026 was 49 out of 100, against 24 in July 2026, so the term's search volume is held back on these pages until a later pull confirms it.

Brand-name searches leave out Browser Use, CAMEL, Composio, Cua, Lindy, Pickaxe and Stagehand: the name is shared with an ordinary word or another product.

2How many people visited

In plain words: These sites got fewer visits from Google than a year ago (-27%), and September 2026 was about the same as August 2026 (-2%).

Miles explains

Judge this line on the year, not the last dot: visits are 27% below a year ago, and 28% below the January 2026 high. One site winning or losing a ranking can swing a single month a lot.

3How many people went looking

People typed a site’s name into Google 31% less often than in October 2025 (-31%). That is the loyalty number: nobody types a name by accident.

US searches a month for the counted brand names, summed. Google Ads data via DataForSEO, to September 2026.

Miles explains

Name searches are the number I trust most. They are down 31%, and nobody types a site’s name by accident, so this shows fewer people coming back on purpose.

4Where the visitors live

About 11 of every 100 visits come from the United States. Outside the US I measure 7 countries one by one; the largest is India.

6Who grew and who shrank

The fastest grower in a year was MindStudio (+1953%); the steepest fall was at CustomGPT (-90%). Big swings are usually one site winning or losing one Google ranking.
