Performance Max network segmentation is now available via API v23
Network segmentation is now available via the Google Ads API for Performance Max campaigns, enabling breakdowns by network, time, device, product attributes, CPC, CPM, and ROAS. Mike Ryan published a first-of-its-kind analysis using 41.5 billion impressions from Smarter Ecommerce (smec), offering deeper insight than the UI-based Channel Performance report.

Why it matters for advertisers
For you, this means PMax transparency is now nearly on par with other campaign types when using the API. Other key additions include campaign-level invoice cost details, campaign start/end time fields, store location data in PerStoreView, Life Event audience dimensions, Demand Gen surface-level conversion rate suggestions, and AI-based audience definition from free text.
