Starting August 18, Google is automatically activating conversion-based customer lists for advertisers already using Enhanced Conversions and Customer Match. Understand what this means for your ad spend and audience targeting.
As of August 18, 2026, Google Ads is automatically turning on conversion-based customer lists for eligible advertisers. If you're already using both Enhanced Conversions and Customer Match in your account, Google will begin processing conversion data to build new audience segments without requiring you to flip a switch.
The auto-enrollment applies specifically to advertisers running both Enhanced Conversions and Customer Match. If you've enabled only one of these features, or haven't set up either, this won't impact your account. The change is broadest for mid-market and larger advertisers who've invested in conversion tracking infrastructure.
Privacy regulations continue to tighten globally, forcing digital advertising platforms to move away from third-party data and cookies. Google is responding by shifting advertisers toward first-party data, information you collect directly from your customers. Conversion-based customer lists let you build audiences using conversion data you've already gathered, making your ad targeting more compliant and more effective as privacy walls rise.
This is part of a larger pattern: Google wants advertisers to invest in direct customer relationships and first-party data collection, not rely on external data brokers or cookie-based targeting.
Starting August 18, Google will automatically begin building conversion-based customer lists using the conversion events already tracked in your account. You don't need to manually activate the feature or change any settings, but you should verify that your Enhanced Conversions setup is capturing the right customer actions.
Once active, these lists segment your customers based on conversion behavior, who bought, who downloaded, who requested a quote. You can then use these segments to retarget past converters, suppress high-value customers from cheaper placements, or build lookalike audiences of people similar to your best customers. All of it runs on data your business already owns.
Data processing begins August 18, 2026. There's no deadline for action on your part, enrollment is automatic. However, we recommend auditing your conversion tracking in the weeks before this date to ensure data quality.
