A real anonymised architecture for an online shop (fashion/home, 5,000 products, two countries) — from one PMax covering the whole catalogue at ROAS 4 to a hybrid structure by margin with standard Shopping, PMax by product family, catalogue Demand Gen, dynamic labels and feeds per country — with the numbers, the step-by-step migration and the role of POAS.
