Attribution Model

What is an Attribution Model?

In advertising, an attribution model will allow marketers to look at the team of ads that contribute to a sale or conversion over an extended period of time. So instead of the traditional method of crediting a sale or conversion to the last ad clicked or viewed, an attribution model will attribute credit to each ad or “touch point” within the sales funnel.

The goal behind attribution modeling is to obtain a full picture of what is happening along each marketing channel and to understand the degree of influence each ad has on a consumers’ decision.  By using an attribution model to track and analyze multiple touch points, marketers can gain new insights, optimize campaigns, and get a more accurate reading on ROI.

Below is a basic attribution model graph.  Notice how the model attributes credit to multiple ads over time, not just to the last ad clicked.

The Pitfalls of Attribution Modeling

The biggest challenge to setting up an attribution model is identifying how much credit to assign each attribution. In other words, a marketer must determine how much influence to assign each touch point or ad.  Does the initial ad get most of the credit or was it the third ad in the sales funnel that was most influential?  This can prove extremely difficult when we consider that there are many other contributing factors, such as the timing of the ad, decay rate of the ad, what products were sold, the amount spent, etc.

A good attribution model should also account for the factor of uncertainty. Was the buyer recommended by a friend? Did they see the product in a magazine ad or on a TV commercial?
In order to ensure accuracy in the credit attributed to each ad, analysts must continually test and re-calibrate attribution models for extended periods of time.  Only then will they have successful models that will allow them to make effective marketing decisions.

Nice Post.
Definitely a fan of an attribution model as opposed to the 'last click'
