You want to check your client's Brand Lift Study(BLS)inDisplay&Video 360 after recently launching a Programmatic Guaranteed deal for their new audio ads.You review the report and learn that the deal didn't receive any significant results.What could be causing this issue?

The reason for not receiving significant results in the Brand Lift Study(BLS)for a recently launched Programmatic Guaranteed deal for new audio ads in Display&Video 360 is that Brand Lift can't be measured for Programmatic Guaranteed deals.Unlike other campaign types,Programmatic Guaranteed deals do not support Brand Lift measurement.The Brand Lift Study is designed to assess the impact of digital advertising on key brand metrics,but this functionality is not available for Programmatic Guaranteed deals.Advertisers should be aware that when using this deal type,traditional Brand Lift metrics may not be applicable. Therefore,the absence of significant results in the Brand Lift Study report for the Programmatic Guaranteed deal is expected due to the limitations in measuring brand lift for this specific deal type.
