We are finally seeing the “Reach similar audiences” function populate across our DSP Advertisers - Excited to start testing and collecting data! What kind of results have you gotten with your initial testing?

• Similar audiences: You can enhance your line item's reach to consumers with similar shopping, streaming, and browsing behaviors or interests as your selected audiences across all inventory sources, regardless of the presence of ad identifiers. Using this feature can enhance the scale and reach of any line item which includes custom-built product or brand audiences. Note that your demographic and location settings will continue to apply. To enable similar audiences, you can click on the checkbox Reach similar audiences in the Audience section.
