Last-click attribution is a marketing measurement model that gives credit for a conversion or sale to the last touchpoint a customer interacted with before completing the desired action. This approach assigns all the credit for a conversion to the final touchpoint, ignoring any previous interactions that may have influenced the customer’s decision. While it is a simple and commonly used method, it can often overlook the impact of other touchpoints in the customer journey and may not accurately reflect the true effectiveness of a marketing campaign.
