Measuring this means focusing on how viewers emotionally encode the message, not just whether they laugh or notice it. Tracking recall after exposure, ad recognition in follow-up surveys, and time spent viewing different formats shows which style sticks. Analyzing confusion or misattributed brands highlights gaps in clarity versus entertainment. Engagement signals like rewatching or sharing act like behavioral heatmaps of memory formation. Insights from these patterns guide refining tone, balancing emotional cues, and tightening brand cues within the ad.
