This data feed will allow you to easily share your e-commerce sites product data with Google Shopping and other channels. At Geta we've used it for quite a few 3rd party integrations.
This module is following the official product data specification from Google. You can easily share the feed through the merchant center or with any 3rd party services or providers.
