Update your customer list

To provide a comprehensive and consolidated view of your Audiences and make audience management and optimization simpler, you’ll find the following improvements in Google Ads:

  • New audience reporting
    Detailed reporting about audience demographics, segments, and exclusions is now consolidated in one place. Click the Campaigns icon Campaigns Icon and open the “Audiences, keywords and content” tab and click Audiences. You can also easily manage your Audiences from this report page. Learn more About Audience reporting.
  • New terms
    We’re using new terms on your audience report and throughout Google Ads. For example, “audience types” (these include similar, custom, in-market, and affinity) are now referred to as audience segments and “remarketing” is now referred to as “your data”. Learn more about the Updates to Audience terms and phrases.

This article explains the steps you need to follow to update and manage your existing customer lists.

Once your customer data file has been uploaded, you have the option of updating your customer list. Learn more about how to create a customer list.

To successfully use your customer data file, it’s important to ensure that you format your customer list correctly.

Refresh your Customer list audiences regularly so that your most important customers remain in your audiences targeting.
