Abstract: In one embodiment, a method for interactive network session tracking from inbound source to net sale includes storing a unique session ID (identifier) in an entry in a session database, and associating the session ID with an inbound source (origin) of the user of an interactive network site. The user's actions, such as page views, product detail views, and shopping cart additions and deletions, can also be stored in the session database associated with the session ID. The unique session ID is embedded in a digital offer that is stored in a transaction database such that net sale data is associated with the session ID. Reporting and correlation of transaction data and the user activity data can be performed offline for analysis of purchase and traffic patterns.
