Case 01
Cut PMax brand bleed 74%, doubled non-brand contribution
Account had stacked four PMax campaigns across catalog tiers. Brand search was being absorbed into PMax at ~36% of total conversions, masking actual incremental performance. We rebuilt asset groups thematic-by-margin, added a brand exclusion list at the campaign level, and forked a feed-only PMax shadow campaign as control.
Within 8 weeks brand bleed dropped to 9%, non-brand contribution to revenue grew from 31% to 50%, and blended ROAS held at 6.4x while incremental conversions grew 41% q/q.
"They were the first agency that talked to me about incrementality without it being a sales pitch."
