Which attribution model gives all credit to the last interaction before a conversion?

The attribution model that assigns all credit to the last interaction before a conversion is known as Last-Click attribution. This model is popular because it is straightforward and makes it easy to determine which final touchpoint influenced the customer's decision to convert. In essence, it suggests that the last interaction has the most significant impact on the conversion outcome, emphasizing the importance of that final touchpoint in the customer journey.

This approach can be particularly useful for businesses seeking to optimize their marketing strategies based on the final channels that drove conversions. While it simplifies the analysis by focusing solely on the last interaction, it may not take into account the contributions of earlier interactions that may have played a critical role in leading a customer to make a purchase decision. However, in contexts where the last touchpoint's influence is paramount, this model can provide clear insights for marketers looking to allocate resources effectively.
