Google Ads Unveils Channel-Level Reporting for Enhanced Campaign Insights
Google announced channel-level reporting for Performance Max campaigns as part of the Google Ads API v23 release. Developers can now retrieve performance metrics broken down by channel (Google Search, Search Partners, Gmail, YouTube, Display, Discover, Maps) at the campaign, asset group, and asset levels. The API will return specific channel enum values instead of the previous generic MIXED value; asset-group-level reporting is available only via the API (not the Google Ads web UI). Channel-level performance data will be available for dates on or after June 1, 2025. The announcement advises developers to upgrade client libraries to v23 and to prepare reporting systems for the new enum values, and highlights that v22 segmentation fields ad_using_product_data and ad_using_video can be combined with the new channel breakdowns for more granular insights.
Major platform (Google) released a technical API update that increases reporting transparency for Performance Max campaigns, changes API behavior (new enum values), and requires developer/client library upgrades—impacting measurement and reporting workflows across the advertising ecosystem.

Google Ads API expands product reporting June 15, 2026
Google announced that starting June 15, 2026 the Google Ads API will broaden product reporting to include data from all Performance Max networks and provide more comprehensive metrics across campaign types and channels (Performance Max, Shopping, Video, App, Demand Gen). Cost and conversion metrics for shopping_product will begin returning data for Video, Demand Gen and App campaigns (previously limited). All campaigns using Google Merchant Center will return results via shopping_performance_view, and Performance Max will expose all networks in that view — which may cause a one-time increase in reported product metrics. The expanded data will be available only for queries covering June 15, 2026 onward; historical requests for prior dates will not include the new metrics.
