Your colleague wants to measure the brand perception, or Brand Lift, on his clients’ new audio ad Programmatic Guaranteed deal. When he runs a Brand Lift Study in Display & Video 360, he doesn’t see significant results for this deal. What’s the reason for this?

Brand Lift can’t be measured for audio ads.
Display & Video 360 can’t support Brand Lift measurement.
It takes several days for the report to show up in Display & Video 360.
Brand Lift can’t be measured for Programmatic Guaranteed deals.
