Google is revamping Merchant Center performance reports on August 24 with four updates including YouTube affiliate separation, definition alignments, expanded ads reporting, and new segmentation options.
SERoundtable reports that Google announced four updates to Merchant Center performance reporting launching August 24, 2026, with retroactive data changes beginning July 1. The changes separate YouTube affiliate commissions from organic traffic, align YouTube reporting definitions with established standards, expand product-level Google Ads reporting across all channels and formats, and introduce new performance segmentation by network—though the network dimension will roll out later. Merchants should expect potential one-time drops in reported organic traffic and increases in ad metrics as these definitions realign across the Google ecosystem.
