We're aligning item-level enforcement across Shopping ads and free listings by extending limited performance enforcements to free listings. We'll introduce enforcement for products that are missing unique product identifiers, such as GTIN [gtin], MPN [mpn] and brand [brand].
Previously, if a product listing was missing these required attributes, the product was immediately disapproved and no longer shown in free listings. With the introduction of limited performance enforcements, products that are missing such attributes will remain eligible to be served but their performance may be limited.

Product identifier requirements: All products require a combination of unique product identifiers. If these required attributes (GTIN [gtin], MPN [mpn] and/or brand [brand]) are not provided, your products will remain eligible to be served but their performance may be limited.
