Google continues to refine Performance Max (PMax) with an increase in Search Themes cap from 25 to 100 per asset group. The update will provide advertisers with increased ability to guide AI-driven campaigns through allowing greater control over how queries are matched.
Search Themes act as a key signal for Google’s automation; therefore, quadrupling the limit grants advertisers the ability to better guide their PMax campaigns. Alongside this, where Performance Max campaigns are highly automated, these increases in Search Themes support improved advertiser control for targeting.
