Measuring Social Network-Based Interaction with Web Content External to a Social Networking System

A social networking system includes a mechanism for generating nodes in the social graph corresponding to web content external to the social networking system. These nodes allow the social networking system to track user interactions within the social networking system about web content external to the social networking system. The web content markup language document(s) include one or more tags, which contain information for defining the node in the social networking system. Users may then interact with the node, and these interactions are tracked by the social networking system. From this, the social networking system generates analytics, which include historical data and user demographic and behavioral information, and which can be provided to the web content provider via the social networking system. A user interface within the social networking system can be used to provide access to the analytics.
