Allow Learning Phase: Give PMax and AI Max campaigns at least 2-4 weeks and sufficient conversions to exit the learning phase before making significant changes.
Embrace Asset Group Granularity: Create multiple asset groups within PMax, segmenting by product, service, or audience, to allow the AI to tailor messaging more effectively.
