Performance Max can scale quickly but needs clean feeds, conversion signals and asset discipline.
What sellers should know.
This page is written for ecommerce teams that need clear decisions, not surface-level definitions.
Asset groups should reflect product categories and buying intent, not random creative sets.
Brand and non-brand impact should be reviewed carefully.
Apex evaluates PMax with MER, product contribution and assisted growth.
