On September 30, Googled made an announcement that the company is expanding Google Shopping listings globally for free.
According to the Google Merchant Center page:
“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.”
To participate, all you have to do is opt in after you sign up for Merchant Center. Once you’re signed up, go to Growth in the left navigation menu and click on Manage programs. After that, just click on Surfaces across Google for more information.
This change will go into effect by the middle of October of this year.
