Last year Google introduced Google Shopping, where the search engine migrated their Merchant Center product to a commercial model via Product Listing Ads through AdWords. Last week, Google announced that they are making some changes to the Google Shopping Feed Specification in order to improve the quality of data that merchants provide. Some of the changes include:
Google says that it will start enforcing the new requirements for new unique product identifiers on July 15, 2013 for merchants within the United States. For all other target countries, enforcement will begin on September 16, 2013. In addition, Google says that non-compliant items may be disapproved and disappear from Google Shopping.
Be sure to keep abreast of the latest product feed changes to ensure that your Google Product Listing Ads do not disappear or lose revenue.
