Starting June 2024, Google Merchant Center will automatically separate supplement feeds linked to multiple primary feeds into distinct feeds.
This adjustment affects merchants who use a single supplemental feed to improve product data for various countries with similar languages. Previously, one supplement feed could be connected to several primary feeds, but now each connection will need to be listed separately.
This update likely stems from the recent feed label changes introduced last month. While the practical benefits remain unclear, this shift complicates feed management for merchants.
