How does the position-based attribution model assign conversion credit?

The position-based attribution model assigns 40% of the conversion credit to the first interaction and 40% to the last interaction. The remaining 20% of the credit is then distributed equally among all other interactions in the conversion path. This model recognizes the importance of both the initial touchpoint that introduces a customer to a product or service and the final touchpoint that closes the conversion. The other options describe different attribution models: "Majority of credit is given to the first interaction, with remaining credit given to other interactions" describes a first-interaction model. "All credit goes to the last click" describes a last-click model. "Majority of credit is split across click interactions, with remaining credit given to any impressions" is not a standard attribution model.
