We are happy to announce the release of a new version 4 of our GooglebaseXML component for Joomla 2.5 and Virtuemart 2.0.x. This component generates a product feed for your Virtuemart store which can be submitted to Google shopping through the Google Merchant Centre.
The component is designed to allow you to match Google's product feed specification exactly, so that Google should accept your feed without problems. The latest version is designed to make it even easier to generate multiple feeds, making it straightforward to submit feeds to Google even for very large sized online stores.
You can find out more by viewing the documentation for the component.
We also have legacy versions available for previous versions of Joomla and Virtuemart. View the documentation for the legacy versions.
