Digital marketing’s fast pace allows for unprecedented testing of what drives ad success. This study combines human coding and machine learning across over 2,300 food, beverage and restaurant video ads, to reveal how sensory cues like “crunch sounds” and human interaction can significantly boost brand awareness, consideration and purchase intent—while some commonly used tactics, surprisingly, fall flat.

In the digital age, marketers are increasingly utilizing online sales promotions. However, this study hypothesized that offline (versus online) media more effectively induce consumer behavioral responses to sales promotion. Field and lab experiments supported this hypothesis, showing that sending print (versus online) coupons increased redemption behavior. This effect was mediated by cognitive engagement with the content and was more pronounced among consumers with low (versus high) brand attachment. These results were consistently replicated across different product categories.
This study provides behavior-based evidence supporting the effectiveness of offline media and highlights brand attachment as a new moderator of the effect. The findings caution against marketers’ overdependence on online sales promotion and suggest that offline promotional media can enhance consumers’ cognitive engagement with the content, leading to better behavioral outcomes.
