Last summer, Google started enforcing its new unique product identifier feed specification for Google Shopping. Google said it was improving support for merchant-defined multipacks. The feed specification clarified how multipack products should be submitted. As it moved toward high-resolution displays, Google also started recommending higher-quality images with at least 800 pixels in height and width.
For products like custom goods, vintage items, collectibles, etc., which don't have unique product identifiers, Google introduced the “identifier exists’ attribute, and updated its requirements on unique product indentifiers.
Last year, Google began disapproving products that didn't have data in the feed for the unique product identifier attributes, demoting products that incorrectly used the identifier_exists attribute, and disapproving products that provided invalid GTINs that didn’t conform to standard GTIN specifications.
Google announced today that additional enforcement is on the way:
Soon we will start to (1) disapprove products with incorrect GTIN, MPN and brand and (2) globally demote products that incorrectly use the identifier_exists attribute. We will continue to ramp up enforcements to find and disapprove products with incorrect GTIN, MPN and brand data in the coming months.
We recommend reviewing product warnings and disapprovals in the Data Quality and Data Feeds tabs in Merchant Center. For pending product disapproval launches, the violations may show up as warnings and eventually show as errors in the UI after the enforcement launch date. For products demoted due to incorrect use of ‘identifier_exists’ attribute, please review your products where it is set ‘false’ to make sure you marked so only for custom goods.
