About Customer Match

Customer Match lets you use your online and offline data to reach and re-engage with your customers across Search, the Shopping tab, Gmail, YouTube, and Display. Using information that your customers have shared with you, Customer Match will target ads to those customers and other customers like them.

As Apple’s App Tracking Transparency (ATT) policies go into effect, your data segments (especially website, app and automatically created lists) and Customer Match lists may be impacted on iOS 14 traffic (including the use of these lists for exclusions). Campaigns promoting web-based conversion goals - particularly those using Customer Match and your other data segments - may also see performance fluctuations. During this time we will be expanding modeled conversions to more iOS 14 traffic.

Customer Match is a useful advertising tool for many business goals, from increasing brand awareness to driving conversions. Here are a few examples of different audiences you can target with Customer Match:

  • On the Search Network and the Shopping tab, you can optimize your campaigns by adjusting your bid based on what you know about your customers’ activities.
  • On Gmail, you can reach your customers or similar audiences using personalized ads at the top of their inbox tabs.
  • On YouTube, you can reach new audiences, by targeting audiences similar to your most valuable customers.
  • On Display, you can reach your customers or similar audiences using personalized ads on the Google Display Network.

How it works

Let's say you want to advertise a new loyalty program to your existing customers with Google ads. Here's how it works:

Step 1 Step 2 Step 3
You create and upload a customer list data file of contact information your customers have given you. Use this template and check this article for formatting instructions. You create or update a campaign to target your Customer Match audience — customers from your uploaded data file who are Google users. When those users are signed in to their Google account, they see your ads as they use the Search Network, YouTube, and Gmail or when they browse on the Google Display Network.

For more information about how Google uses the data files you upload for Customer Match and how the matching process works, read How Google uses Customer Match data.

Customer Match is currently available on Search, the Shopping tab, YouTube, Gmail, and Display.

User choice and control

Google users can control the ads they see on Google services, including Customer Match ads, in their Google Ads Settings.
