Abstract Despite firms’ continued interest in using influencers to reach their target consumers, academic and practical insights are limited on what levers an influencer can use to enhance audience engagement using their posts. We demonstrate that posting stories with or about people whom they share close ties with—such as family, friends, and romantic partners—can be one effective lever. Content that incorporates close social ties can be effective for several reasons: it may increase perceptions of authenticity, enhance perceived similarity, increase the perception that the influencer possesses more warmth, and could satisfy viewers’ interpersonal curiosity. We analyze texts and photographs of 55,631 posts of 763 influencers on Instagram, and after controlling for several variables, we find robust support that consumers “like” posts that reference close social ties. Furthermore, this effect enhances when first-person pronouns are used to describe special moments with these close ties. We supplement the Instagram data with an experimental approach and confirm the relationship between close ties and consumer engagement. Managerially, this is a useful insight as we also show that sponsored posts tend to be perceived negatively compared to non-sponsored posts; yet, embedding social ties on the sponsored posts can mitigate consumers’ negative responses.

Abstract Incidental waits are an unavoidable element of the consumer experience on any digital platform. Firms typically utilize no animation or single-speed, repeated animations during these waits. How might the use of such animations and their visual qualities influence perceived waiting time? Can simple design changes by managers influence the customer experience? Although prior research suggests a linear relationship in which faster animations reduce perceived waiting time, we find a convex relationship between animation speed and time perception: moderate-speed animations minimize perceived waiting time compared to no, slow-moving, or fast-moving animations (experiments 1a–1c). We refer to this effect as the convex effect of animation speed. This effect occurs when people use animation speed to infer wait time (experiment 2a) and because moderate-speed animations draw more attention than static images or faster animations (experiment 2b). Animations that introduce dual-attention elements (experiment 3a) or atypical animations (experiment 3b) shift attention away from movement speed, attenuating this effect. Finally, this effect extends to website click-to-landing rates (experiment 4), conversion rates (experiment 5), and product evaluations during mobile shopping (experiment 6). These findings highlight the practical value of optimizing animation speed in user interface design to enhance both customer experience and business outcomes.
