The google-trusted-stores tag should be used for questions related to integration with the Google Trusted Stores program for E-Commerce retailers
Google Trusted Stores is a Google program which offers purchase protection, merchant ratings and reviews, and merchant verification to e-commerce shops.
The program gathers order metrics from retailers and tracks the order volume and customer satisfaction. Qualifying for the program requires submitting this data for a period of time before Google awards the Trusted Store status. Once a store becomes a Google Trusted Store then a badge is displayed on the site via a javascript integration and customers are prompted at check-out to opt-in for order protection and to rate their experience with the retailer.
Trusted Stores are also featured in Google Shopping listings, with the GTS badge being displayed for listings belonging to Trusted Stores.
