A new returns section has been added to the structured data type definitions within Google’s product structured data document. You can use the following new properties to make your merchant listing eligible to show return policy information, including return fees and the window of time to return a product, Google explained. The required properties include:applicableCountry: The country code that the return policy applies to, using the two-letter ISO 3166-1 alpha-2 country code formatting. If you have outstanding shipping and return policies, you may want to highlight that through Google Merchant Center and structured data so that can be visible within Google Search.
