Implementation of TradeDoubler Tracking

This is a technical guide on how to implement the TradeDoubler sales tracking including the Merchant review functionality.

Technical introduction TradeDoubler tracking system "G2", uses both persistent cookies and session cookies to track the traffic generated within the network. Session cookies are used when users doesn't allow persistent cookies. By combining both session and persistent cookies, set by both TradeDoubler and the advertiser, we get very reliable tracking solution.

In short: If a visitor blocks persistent third-party cookies, the advertiser will use a first party cookie. And if no persistent cookies are allowed, we use a session cookie instead. Since the session cookie is deleted when the browser is closed the tracking will only be possible within the session in this case.
