Match the following attribution types to their correct definition.

First Touch Attribution (3) assigns 100% of the credit for a conversion to the very first platform or touchpoint a user interacted with. This model is useful for understanding initial awareness and the effectiveness of top-of-funnel marketing efforts. Multi-Touch Attribution (2) distributes credit across all platforms or touchpoints that influenced a user's journey leading to a conversion. This approach provides a more holistic view of how different marketing channels contribute throughout the customer lifecycle, acknowledging that conversions are rarely the result of a single interaction. Last Touch Attribution, not directly matched here but implied, would give all credit to the final interaction before conversion.
