Google Base Feedgator

Automatic Google Base (Google Shopping also called "Google") Shopping feed generator and uploader. This efficient application generates a valid Google Base Product Feed that has to be uploaded to your Google Account (You need a Google Marketplace free account that can be opened in 5 minutes).

Once the feed containing information on the products you are selling is uploaded (Picture, price, URL of the site, description etc...), they will appear within a day or two in Google Shopping search engine (different than the general search engine).
