Create a customer list

Customer Match lets you target ads to your customers using the data they share with you. You create a CSV file including customer data and upload it into Google Ads to incorporate this targeting into your campaigns.

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

If you run into any issues with the upload process, learn how to fix customer list issues.

This article explains how to upload your data files to create customer lists.

Before you begin

You can use all data types specified in the formatting guidelines below in the new Google Ads experience. Determine which Google Ads experience you’re using.

 

Instructions

The new Google Ads experience is now the exclusive way for most users to manage their accounts. Note, automatic targeting is only available in the new Google Ads experience.

The following instructions will guide you through the process of uploading a customer customer data file to create a new Customer list.

    2. If you choose to hash your data, make sure it meets the requirements described in the Formatting guidelines for Customer list data files of this article. 
  7. Choose your new file.
