Today we announced that we’re bringing free listings to the Shopping tab in countries across Europe, Asia, and Latin America. Just as we don't charge sites to be part of the Google Search index, listings for participating retailers are eligible to appear in these results at no cost to them. Paid listings will continue to appear in ad slots and will operate in the same way as Shopping ads do today.
This change will take effect by mid-October 2020.
How to participate
To show your products in free product listings on the Shopping tab, opt in when you sign up for Merchant Center. If you already have an account, navigate to Growth in the left navigation menu, click Manage programs, and then select Surfaces across Google to learn more.
