How to access CCMN referral traffic in Google Analytics

Referral traffic from the Cars Commerce Media Network (CCMN) helps you understand how in-market shoppers move from digital experiences to your dealership website. Reviewing this traffic in Google Analytics 4 (GA4) helps you understand engagement and evaluate how CCMN products contribute to your funnel.

In this article, you’ll learn how to locate and review CCMN referral traffic in GA4, including traffic from In-Market Display (IMD), In-Market Video (IMV), VIN Performance Media (VPM), and Cars Social.

1 Log in to Google Analytics

• Sign in to your GA4 property for your dealership website
  
• From the left-hand navigation, click Reports.

2 Open the Traffic Acquisition report

From the Reports menu:

• Select Acquisition
  
• Click Traffic acquisition

This report shows how users arrive at your site.

3 Update the primary dimension

By default, the report displays Session default channel group.

Change the dimension to:

• Session source / medium

This allows you to view traffic originating from Cars.com and CCMN media.

4 Filter for CCMN referral traffic

Look for traffic with:

• Source: cars.com
