Customer Match
A targeting feature that lets advertisers upload first-party customer data such as email addresses so platforms can match those users and build audiences for search, YouTube, or display campaigns.
How Customer Match works in practice
Customer Match becomes more valuable as third-party audience data weakens because it is built from real first-party relationships rather than inferred interest pools. The strongest uses are not just retargeting existing customers, but excluding them from acquisition campaigns, building lookalikes from high-value users, and tailoring messaging for upsell or reactivation audiences. Match rates vary by platform and list quality, so the operational discipline around data hygiene matters as much as the ad strategy itself.
