The model comparison report (or attribution model comparison report) is used to compare different attribution models to each other. This comparison is carried out to determine how a marketing channel can be valued from a different perspective.

An attribution model is a set of rules or algorithm which is used to determine how credit for conversion should be attributed to various touchpoints in a conversion path.

The attribution model that you select as a starting point for comparison is called the ‘Base model’.

The attribution model that you select for comparing with the base model is called the ‘Potential Model’.

The model comparison report is similar to the ‘Model Comparison Tool’ report in GA multi-channel funnels.

In order to access and use the ‘Model Comparison’ report follow the steps below:

Step-1: Navigate to https://analytics.google.com/analytics/attribution/ 

Step-2: Click on the ‘Model Comparison’ link on the left-hand side:
