What Is Multi-Channel Attribution?

Multi-channel attribution is a method used in marketing analytics that assigns credit to each touchpoint or interaction in marketing channels that a consumer engages with before completing a desired action, such as a purchase. This process helps marketers understand which channels and interactions within their marketing mix have the most influence on the decision-making process of the consumers. By accurately attributing success to the various channels, marketers can optimize their budgets and strategies to enhance ROI.

Importance of Multi-Channel Attribution

Multi-channel attribution provides insight into the effectiveness of different marketing efforts and helps allocate marketing resources more effectively. Understanding how each channel contributes to conversion allows businesses to invest more wisely in advertising and promotions, enhancing both efficiency and outcomes.

Key Models of Multi-Channel Attribution

1. Last Click Attribution

This model gives all the credit for the conversion to the last touchpoint before conversion. It’s straightforward but often oversimplifies the contribution of other channels that may have assisted in the conversion process.

2. First Click Attribution

Opposite to the last click, this model attributes all the conversion credit to the first interaction. While this highlights the channel that initiated customer engagement, it ignores subsequent interactions that may have been crucial to conversion.

3. Linear Attribution

A linear model assigns equal credit to all the channels that the customer interacted with throughout their journey. This approach acknowledges that each touchpoint played a role in the conversion, though it doesn’t weigh any single touchpoint more heavily than another.

4. Time Decay Attribution

This model gives increasing credit to touchpoints that occur closer in time to the event of conversion. It is based on the assumption that the final interactions before conversion are the most significant.

5. Position Based Attribution

Also known as the U-shaped model, it assigns a larger share of the credit to the first and last interactions, with the remaining credit distributed evenly among the middle interactions. This model recognizes the importance of the introduction and decision phases in the customer journey.


Multi-channel attribution is crucial for marketers seeking to understand the impact of their integrated marketing strategies across various platforms. By using sophisticated attribution models, marketers can gain accurate insights into the performance of each channel and tailor their efforts to maximize effectiveness and efficiency. As the digital landscape grows increasingly complex, the ability to dissect and interpret this data becomes ever more critical in shaping strategic marketing decisions.
