Google is expanding Performance Max reporting in Google Ads, adding asset-level segmentation and a beta channel performance report. The features are rolling out gradually across advertiser accounts.
What's new
Asset reports now support segmentation by device, time, conversion action, and network. A new Network with search partners view is available in asset group reports.
The channel performance report (beta) breaks down results and costs by Google surfaces in a single view. It includes ROI-style columns, budget distribution across surfaces, and account-level bulk downloads. See the official updates.
How to read the data
Availability and access
The channel performance report is in beta and will roll out gradually (updates). Access it in Google Ads under Insights and reports (help doc).
Background
Performance Max is an automated campaign type that serves ads across YouTube, Display, Search, Discover, Gmail, and Maps. Bidding, budgeting, creatives, and placements are managed by Google's systems. The channel performance report shows how each surface contributes to primary goals, while asset reports list individual assets with impressions, clicks, and costs tracked independently.
