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, Cassidy, Composio, Cua, Lindy, Pickaxe, Rasa 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 (-44%), and September 2026 was a weaker month than August 2026 (-3%).

Miles explains

Judge this line on the year, not the last dot: visits are 44% below a year ago, and 55% below the October 2025 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 7344% more often than a year ago (+7344%). 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 up 7344%, and nobody types a site’s name by accident, so this shows more people coming back on purpose.

4Where the visitors live

About 12 of every 100 visits come from the United States. Outside the US I measure 18 countries one by one; the largest is India.
