Last-click attribution is a success measurement model in affiliate marketing that credits the last touchpoint before a purchase or conversion with full acknowledgment. This means the advertiser the customer interacted with last before completing the action is seen as the key to success. This approach has the advantage of clearly identifying the decisive final step in the purchase decision.

All previous contacts the customer had with ads or affiliate offers are ignored for attribution. This model is popular because it makes billing transparent and easy to understand. However, it doesn’t capture the contributions of other touchpoints in the customer journey.

Last-click attribution offers a simple and practical way to measure the effects of individual publishers directly. For a more comprehensive evaluation, complementary models can also be used. Overall, last-click attribution is a proven tool to steer marketing campaigns precisely and track success accurately.
