The session window in affiliate marketing defines the time frame during which a user action—such as a purchase or sign-up—is credited to a Publisher. Within this window, all user activities originating from a Publisher's link are tracked and rewarded. This ensures that the right Publishers are recognized and compensated for their referrals.

This time window typically starts with the click on a Publisher's link and ends after a specified period, which varies depending on the program. If an action occurs within this duration, it is attributed to the Publisher. This way, the effectiveness of a Publisher's marketing efforts and the revenue generated through their recommendations become clear.

Accounting for the session window is crucial for transparent and fair settlement within the affiliate platform. By clearly defining and tracking this period, successes can be measured accurately and attributions are error-free.

In professional use, the session window improves traceability and optimizes collaboration with Publishers. It guarantees all parties a fair chance and enables efficient evaluation of marketing activities.
