Com GoogleBaseXML

The product listing generated by the component is in XML format, and can be manually uploaded, or submitted to Google Merchant Center for scheduled upload. Once uploaded to your Google Merchant centre account the feed can be used for Google Product Search, Google Product Ads, and Google Commerce Search

You can find more about how it works here in the documentation.

You can sign up for the Google Merchant Center at http://www.google.com/merchants/.

Please note that Google Product search is currently only available for the following countries: USA, UK, Germany, France, Netherlands, Italy, Spain, China, Japan and Australia. The data feed generated by our GooglebaseXML component can be used to submit products for any or all of these target countries. However Google product search will reject product listings that are not in the language of the target country.
