Abstract:
The subject technology provides a session associated with web site or application traffic data. An analytics tracking data communication is received. The subject technology determines analytics tracking data from the received analytics tracking data communication in which the analytics tracking data includes data for tracking an activity associated with a web site or application and includes visitor information. A new session associated with the analytics tracking data is created if it is determined that the activity is associated with an initial visit of a unique visitor corresponding to the visitor information. The subject technology determines campaign information for populating the new session associated with the analytics tracking data. The analytics tracking data including the determined campaign information is then stored.
