Which is TRUE regarding Brand Lift Studies on TikTok?

Multi-cell experiments are a core component of Brand Lift Studies. They allow advertisers to test different campaign variables (e.g., creative, targeting, bidding strategies) against each other or against a control group to isolate the impact of each variable on brand metrics. This helps optimize future campaigns by identifying the most effective elements. Surveys are typically sent within 2-3 days, not 24 hours, to allow for ad exposure and recall. While a significant number of responses are needed, 1,000 per group is a general guideline and not a strict minimum for all studies, as required sample size depends on desired statistical power and effect size. Ad Recall is a standard, not optional, question in most Brand Lift Studies as it directly measures memorability.
