Performance Max control loss: asset groups and insights
PMax alone hides where spend actually goes.
Performance Max bundles Search, Display, YouTube and Shopping — easy setup, hard transparency. Without spend visibility, budget leaks to brand traffic or low-quality placements. PMax management needs insights reports and asset group discipline.
Asset group structure
Product/service segments per asset group: different headlines, images, URLs. Add audience signals (custom segment, remarketing) to each.
Test final URL expansion on vs off; when on traffic may land on irrelevant pages.
- Asset group per segment
- Audience signal required
- URL expansion A/B
- Min 5 images 5 headlines
Insights and placements
Weekly PMax insights: channel split, search terms (if available), asset performance. If Display/Video >40% consider separate campaigns.
Brand search can inflate in PMax — separate brand Search and exclusion lists.
Feed and Shopping component
PMax Shopping fails if Merchant Center has errors. Fix catalog feed errors first.
ROAS targets depend on feed quality and margin; not one target for all SKUs.
Conversion goal selection
PMax optimises all primary conversions — make micro events secondary. Purchase or qualified lead as primary.
On new accounts collect volume before tROAS instead of Maximize conversion value.
Balance with manual campaigns
Brand Search + PMax non-brand in parallel; don't leave PMax alone. Brand campaign feeds search term data.

Reporting
PMax-specific: asset group ROAS, new customer acquisition, search category insights. Agency reports must show channel breakdown.
