Performance Max (PMax) is Google newest and most automated campaign type. But automation without strategy leads to wasted spend and poor results.
Mistake 1: No Asset Group Segmentation
Running all products or services in one asset group means Google cannot optimize effectively. Create separate asset groups by product category, audience, or intent.
Mistake 2: Ignoring Brand Exclusions
Without brand exclusions, PMax will cannibalize your branded search campaigns and report inflated ROAS from easy conversions.
