Google Ads is testing a Customer Match option called enhanced matching, which pairs an advertiser’s consented user lists against publisher consented lists to widen audience reach, according to Google’s own help documentation. The feature works in environments without third-party cookies and lets advertisers upload email addresses not tied to a Google account, a gap traditional Customer Match cannot fill.
Membership under enhanced matching lasts a maximum of 60 days, compared with 540 days for standard Customer Match lists. That shorter window means teams running always-on campaigns will need to refresh audience lists roughly nine times more often to keep coverage current.
Advertiser Alec Perelman said on LinkedIn that testing the feature on an exact and phrase match campaign produced search query results he called inappropriate matches, and he disabled it. Search teams piloting Customer Match should treat that report as a reason to audit query-match quality before scaling enhanced matching broadly.
