Your colleague wants to check the Brand Lift Study(BLS)on his client's new audio ad Programmatic Guaranteed deal.When he runs aBL S in Display&Video360,hedoesn'tfind any significant results for the deal.What could be the reason?

If your colleague is unable to find significant results for the Brand Lift Study(BLS)inDisplay&Video 360 concerning hisclient's new audio ad Programmatic Guaranteed deal,the likely reason is that Brand Lift cannot be measured for Programmatic Guaranteed deals.Brand Lift studies are typically designed for campaigns where impression-level data is available for analysis,and Programmatic Guaranteed deals,which involve reserved inventory and fixed pricing,do not provide the granularity needed for Brand Lift measurement.InDisplay&Video360,Brand Lift Studies are better suited for campaigns where impressions are auctioned,like those in the open auction or private auction setups.Therefore,the absence of significant results in this context is expected due to the nature of the deal structure.
