As I am sure you are all aware, Google is making some changes to their Google Product Search (GPS) feeds as of May 3, 2011.
They are now requesting Unique Product Identifiers (UPI) to be added to specific listings. If your items do not have these identifiers they will be rejected from Google Shopping.
Below you will learn what UPI's are and what is needed to keep your specific items in compliance. And please remember, we are here to help walk you through this.
