Influencer marketing is a popular strategy to connect with consumers. However, influencers’ use of overly high-arousal language in promoting products (e.g., “it's totally AMAZING!”) has raised questions about their true motivations. This article investigates how high-arousal language in micro- versus macro-influencers’ sponsored posts might shape engagement. A multimethod approach, combining automated text, image, video, and audio analyses of thousands of Instagram and TikTok posts with controlled experiments, demonstrates that high-arousal language increases engagement with micro-influencers, but it decreases engagement with macro-influencers, seemingly because it makes micro- (macro-) influencers appear more (less) trustworthy. Yet the negative effect of arousal for macro-influencers can be mitigated if their posts provide counterbalanced valence (both positive and negative assessments) or if they indicate an informative, rather than commercial, goal. These findings deepen understanding of how language arousal shapes consumer responses, reveal a psychological mechanism through which language arousal affects perceptions, and provide actionable insights for crafting more effective social media content.

The vast amount of content on social media platforms makes it challenging for firms to create posts that get noticed. An increasingly popular approach to increase customer engagement relies on text overlays, where text is placed directly on images. Such practices raise questions of how to balance the visual and text elements for the best impact. Three key factors, commonly used by practitioners, can trigger engagement because of their visual salience: (1) the degree of dynamism or implied motion in the image as well as the (2) size and (3) centrality of the text overlay. Using multiple methods, including field studies, online experiments, and managerial interviews, the authors establish that a text overlay that is too large and centrally placed, combined with a dynamic image, has negative effects on consumer engagement, because these design combinations make the post visually unappealing. The authors leverage these findings to develop an interactive app that can help managers compose more engaging multimodal social media posts.

To date, the literature offers multiple suggestions for how to recover from service failures, albeit without explicitly addressing customers’ negative, high-arousal states evoked by the failure. The few studies that do address ways to improve negative emotions after failures focus on face-to-face interactions only. Because many customers today prefer to complain on social media, firms must learn how to effectively de-escalate negative, high-arousal emotions through text-based exchanges to achieve successful service recoveries. With three field studies using natural language processing tools and three preregistered controlled experiments, the current research identifies ways to mitigate negative arousal in text-based social media complaining, specifically, active listening and empathy. In detail, increasing active listening and empathy in the firm response evokes gratitude among customers in high-arousal states, even if the actual failure is not (yet) recovered. These findings provide a new theoretical perspective on the role of customer arousal in service failures and recoveries as well as managerially relevant implications for dealing with public social media complaints.

Organizations lose billions of dollars due to inadequate customer service. To improve service, and enhance customer satisfaction, frontline employees’ (FLEs) use of relational communication may be key. During online customer service chats, FLEs provide key information and offer solutions, but they also can build customer relationships through conversations. In this article, we establish how relational perceptions get evoked in conversations and what influences they have for the outcomes of customer service interactions. Accordingly, we present an empirical field study that illustrates how FLEs influence customer satisfaction by mirroring or complementing four key themes, in line with relational communication theory: intimate communication, task orientation, assertiveness, and composure. Our results indicate that FLEs should mimic customers’ use of intimate communication and task orientation, complement their assertiveness, and exhibit high levels of composure. Moreover, FLEs should emphasize their task orientation at the conversation's outset, gradually incorporate more intimate communication as it progresses, and adopt assertiveness late in the service chat. These insights, corroborated by four experimental studies, underscore the significance of FLEs’ relational communication. Our findings highlight the value of training FLEs to tailor their word choices adeptly, and leverage the potential benefits of text-monitoring tools, which can help FLEs increase relational perceptions and satisfaction among their customers.
