Google this month announced a new update on the Combined Audiences in DV360. Combined Audiences will be more flexible, accepting the AND combination of generic Google audiences with first-party audiences. Until now, generic Google audiences and first-party audiences could only have the combination OR.
Advertisers will also be able to do target combined audiences with other audiences types on Line Item level. Google says that will also allow the inclusion of more than one combined audience per line item. Until now, only one combined audience coult be targeted.
Combined Audiences is available in DV360, on Advertiser > Audiences > All Audiences. Advertisers can create audiences from multiple first- and third-party audience lists, as well as interest-based Display & Video 360 Audiences lists for affinity and in market audiences.
