Marketers increasingly use social media platforms as a promotion channel, and doing this, they prefer highly interactive social media because it allows consumers to socialize and network better. However, in this media, attention is often restricted towards primary purpose only as a result of the level of interactivity, thereby affecting consumer response towards the advertisement(ad). In this setting, the study analyzes the role of media interactivity and the effects it has on the reaction of customers towards the social media ad. Further, the study also introduces the conditional role of message relevant aspects, such as message vividness and anthropomorphism, and examines the intervening role of flow experience. Results from a between-subjects study indicate that interactivity hurts the consumer ad reactions. It also suggests that the right use of message relevant aspects can mitigate these adverse effects. Thus, the study makes a significant contribution to the literature and practice regarding the effects of social media interactivity which is relatively recent and has been overlooked by past researchers.
