Google expands Performance Max product reporting to include all advertising networks
Google has updated Performance Max reporting to include product-level data across all advertising networks, resulting in a one-time increase in reported metrics for many accounts.
1. Expanded Reporting Scope
As of June 15, 2026, Google has broadened product-level reporting for Performance Max campaigns. Previously, metrics such as cost and conversions were limited to data from the Search network and Standard Shopping campaigns. The updated reporting now incorporates product performance data across all eligible networks, including Video, App, and Demand Gen campaigns, where applicable through the Google Merchant Center.
2. Impact on Metrics
This change is intended to provide advertisers with a more comprehensive view of how products perform across Google’s entire advertising ecosystem. However, the update has resulted in a one-time increase in reported metrics, such as clicks and impressions, for many accounts. Because this shift reflects an expanded scope of measurement rather than a change in actual campaign performance, historical data comparisons may be complicated.
3. Recommendations for Advertisers
Google Ads specialists advise advertisers to account for these reporting changes when analyzing month-over-month performance to avoid misinterpreting the data as a sudden improvement in results. To better understand the source of campaign activity, advertisers are encouraged to use the "Network (with search partners)" filter to break down performance by specific channels.
