Google AdWords announced a new Feed Rules to manage product data feed for merchant center.
Google said, “To make feed management easier, we’re excited to introduce Feed Rules, a self-service tool to help you transform your existing data from your inventory management systems into the format accepted by Google Shopping. Feed Rules helps you streamline your data feed uploads, whether you’re already running Shopping campaigns or you’re just getting started.”
Once new rules are specified for a feed, all uploads of this feed in future will be processed as per these rules.
