Detailed definition
With PMax you supply the assets (images, video, headlines, descriptions), the signals (audience suggestions) and a conversion goal, and Google AI optimises which asset goes where. The advantage: high scale plus AI optimisation. The disadvantage: it is a black box (you cannot see clearly where the budget went). The best result: Search for brand queries combined with PMax for generic queries.
Examples
- PMax + a product feed for e-commerce = scale comparable to Google Shopping.
