PMax + feed optimisation: +41% revenue on the same budget

An online store running Performance Max in Google Ads. The budget was flat and so was revenue: the campaigns ran on top of a product feed nobody had prepared for them — no structure, generic titles, incomplete attributes.

We started with the feed, not the campaigns. The Google Merchant Center feed was rebuilt, and the Performance Max structure rebuilt around it.

• Product titles, attributes and categories written to match real search queries.
• Asset groups and audience signals per product category instead of one campaign for everything.
• Optimisation on revenue from real orders, not on clicks.

On the same budget, revenue grew 41% in the target period, conversion rate by 2.2 points, ROAS 2.7×. Total campaign revenue growth: 148.8%.
