A method and system are described for tracking user activity related to network resources using a browser. According to an exemplary embodiment, a user-initiated activity related to a network resource is detected in the browser. The detected user-initiated activity is associated with the network resource to form an activity-resource pair. The activity-resource pair is associated with a record in a data store related to the detected activity or the network resource. By associating the activity-resource pair with records in the data store that relate to the network resource and/or the detected activity, the information in the data store can be used to add context to and provide insight into users' browsing activities.
