If a person wants to opt in to the Product Ratings Program, where should they go?

To opt in to the Product Ratings Program, a merchant must use Google Merchant Center. This platform is specifically designed for merchants to upload product data, manage their product feeds, and control how their products appear across Google properties, including Shopping ads. Product ratings are directly linked to the product data submitted through Merchant Center, making it the central hub for managing this feature. Product feed is a component managed within Google Merchant Center, not a separate platform for opting into programs. Google My Business is for managing local business listings and is unrelated to product ratings for Shopping ads. Google Ads is used for managing ad campaigns and bidding, but the initial setup and management of product ratings happen in Merchant Center.
