When shopping, people would like to know the total price of the products that they are purchasing, including the shipping price. The shipping speed, cost, and return policy are major factors that shoppers consider when buying online. When shipping cost is too high, the shipping time is not fast enough, or return information is not clear, consumers will not complete the purchase. Displaying the shipping and return information clearly and upfront is critical to the success of online sales.
Google can already display product pricing and now, it will also be eligible to display shipping and return information in the search result listings. At this time, it is only available in Google Search in the US but it is expected to roll out in more countries soon.
To show shipping and returning information on product search results, add the information using structured data markup similar to how you have marked your products. If you already submit your product information to Google in the Merchant Center, Google will use your Shipping & Returns information from Merchant Center the same way. If your products don’t have shipping and return information or the shipping and return information was added incorrectly, you’ll receive warnings in the Merchant Listings report and via email notifications.
