Google is prompting advertisers to update their brand guidelines in Performance Max campaigns, as these are now managed at the campaign level. This change became default for all new PMAX campaigns starting July 15, 2025.
The update is part of Google’s broader migration to centralize brand guidelines, moving them from asset group level to campaign level for better consistency.
Advertisers are encouraged to review these campaign-level settings and add additional brand details such as colors and font to ensure consistent creative output across channels.
