Google is reportedly testing an increase to the search themes limit for Performance Max campaigns from 25 to 50 per asset group, as noted by Thomas Eccel in a LinkedIn post. Currently, the official help documentation states the limit is 25, but the expansion could provide advertisers with enhanced flexibility in targeting. This allows businesses to offer more comprehensive insights into customer search behavior and potential conversion topics. A screenshot shared by Eccel illustrates the potential new limit, although many users have not yet observed this change in their accounts.
