Similar audiences make it easy for you to find new customers by expanding the reach of your remarketing and Customer Match lists. Previously, you were only able to see estimated list sizes for your similar audiences when applying them to campaigns. To make it easier to see your expected reach with new customers, we’re making the estimated list size available directly in the Audience Manager in Google Ads.
To start, these estimates are available for Search audience lists with more than 20,000 users, and for YouTube audience lists with more than 5,000 users. We’re working on expanding coverage in the future.
Check out our best practices guide to learn how you can use similar audiences with your first-party data to find new, qualified customers.
