An Update on Unique Identifiers in the US

Over the past two months, we've posted about our plans to change the way we display results to help users access all the information we have on a product from one "product page." This week, we have begun to make these changes in the United States. Product offers in the Electronics, Books, and Media categories that are submitted without Unique Product Identifiers may not be listed, or may appear in a lower position in the results. We recommend checking the Data Quality tab in your Merchant Center account to see examples of products which may have missing or incorrect identifiers, and as always you can refer to our Help Center for more information.
