Use Rating Column with the Bamboo Rating Web Part to rate site pages, rich content pages and Web Part pages. Once Rating Column has been added to the container library, such as the Site Pages Library, and Rating Column has been added to each desired site page or Web Part page, Rating Column is displayed on the page for users to rate pages.
Use Rating Column to rate pages just as you would for lists or libraries. See How to Use a Bamboo Rating Column in a List or Library for more information.
