Google Broadens Performance Max Product Reporting to All Networks, Triggering Metric Jumps
TLDR
Google expanded Performance Max product reporting to include all eligible networks as of June 15, causing one-time metric increases that reflect broader measurement scope, not improved performance.
Search Engine Land reports that Google has updated Performance Max product-level reporting to encompass data from all eligible networks—including Video, App, and Demand Gen campaigns—rather than Search network activity alone. The shift means advertisers will see sudden spikes in impressions, clicks, and conversions that don't reflect actual campaign improvements but instead signal expanded measurement. Anu Adegbola advises advertisers to use network filters when analyzing data and add context to month-over-month comparisons, since pre- and post-update reports aren't directly comparable.
