The static brand ad ran in the first week of the campaign with the second week running the multiple dynamic ads.

The contextual dynamic ads out performed the brand ad for spontaneous ad awareness and prompted ad attribution. // Any brand awareness +3% +60% // Spontaneous brand awareness +22% // Prompted ad attribution // Brand creative // DCO creative People exposed to the brand ad only (Wave 1) and those only exposed to the dynamic contextual ads (Wave 2) were asked about statements they agreed with.
