Where should someone go to opt into the Product Ratings Program?

The Product Ratings Program is designed to display product reviews and ratings in Google Shopping ads and on product listings. To participate in this program, a merchant needs to manage their product information and settings, which is done through the Google Merchant Center.

The Google Merchant Center serves as the hub for advertisers, allowing them to upload product data, monitor performance, and manage their online marketing strategy for ecommerce. By opting into the Product Ratings Program specifically through the Merchant Center, merchants can ensure that their product information is properly linked to the reviews they wish to display.

The other options do not serve the purpose of opting into the Product Ratings Program. Google Ads is primarily focused on ad campaign management, the product feed is where product information is submitted but not where the program is opted into, and Google My Business is related to business information for local search visibility rather than product data management in an ecommerce context. Thus, the appropriate and correct venue for opting into this program is the Google Merchant Center.
