Yes, it is possible to launch a Brand Lift even if your campaign has already ended. However, there are a few important guidelines to ensure the reliability and relevance of the results.
Ideally, a Brand Lift should be launched once your campaign reaches around 70% completion, as this timing ensures proper exposure and maximizes the accuracy of the measurement. Still, late requests do happen. In those cases, running a Brand Lift remains feasible, but with some considerations:
If the campaign ended more than one month ago, we recommend not launching a Brand Lift. After this timeframe, ad recall becomes too diluted, reducing the ability to extract meaningful insights.
As with every Brand Lift, your campaign must have reached 100,000 unique impressions to initiate the study.
Finally, when launching a Brand Lift after the campaign has ended, expect the process to take longer — both in terms of response collection and delivery of the full report.
This approach ensures that even in post‑campaign scenarios, your Brand Lift maintains consistency, statistical reliability, and actionable results.
