Google Product Search (formerly known as Froogle) is a price comparison service launched by Google. It is currently in beta test stage. It was invented by Craig Nevill-Manning. Its interface provides an HTML form field into which a user can type product queries to return lists of vendors selling a particular product, as well as pricing information. Product Search is only available for selected countries at this point.
Google Product Search is different from most other price comparison services in that it neither charges any fees for listings, nor accepts payment for products to show up first. Also, it makes no commission on sales. Any company can submit individual product information via Google Base or can bulk submit items for inclusion. Google sells advertising through AdWords to be displayed in Product Search results adjacent to the unpaid results.
