Google Base will host your item details and images. It will then supply a unique URL (web address) where searchers can visit and view your content. This URL will be activated within a few hours after you publish your item.
You can submit multiple items to Google base using Bulk Upload. Google Base will accept bulk uploads in Tab-Separated, RSS 1.0, RSS 2.0 and Atom 0.3 formats. This means that content providers who already have RSS feeds can easily submit their content to Google Base without requiring much additional work.
You can describe any item you post with attributes, which will help people find it when they search Google Base. Depending upon your item, it may also be included in the main Google search index and other Google products like Froogle and Google Local.
