If you access the Brand Lift tab inside the Campaign Overview in Ads Manager and don’t see your study results yet, there’s no need to worry — your data is on its way.
When no results are displayed, it simply means that the survey distribution to the two respondent groups is still in progress. As soon as the data collection phase is completed, all results from your Brand Lift study will automatically appear within the tab.
Important note: Your dedicated Account or Project Manager will promptly inform you as soon as the results are ready, so you can access and review them directly in the Ads Manager.
