Are there any add-ons to create a google base data-feed, we used to have a modified one in our 2.1.4 site, but the newer 3.0.06 doesn't have anything. Thanks
Yes, the Data Feeds addon. If you haven't already activated it, do so under Administration>Addons. You can then access the data feeds via Administration>Data Feeds. Now you can build a data feed with all the required fields. You'll need to create Product Features (presume you already have given the fact you previously used Base) for things like Brands, MPN, UPC, etc as per the requirements for your Product Listing Ads targeted country.
Found it, Many Thanks
