Abstract
PurposeThis study investigates the antecedents that nudge followers of social media (SM) influencers into brand evangelism (BE). In doing so, we study how influencer-related attributes such as their homophily, trust, and popularity impact their followers’ BE. Additional interlinkages pertaining to popularity, content, warmth, and prestige are examined, impacting BE.Design/methodology/approachA cross-sectional survey obtained information about the focal constructs from 206 participants. Quantitative procedures using partial least square-based structural equation modeling were implemented to analyze the collected data and the proposed relationships.FindingsThe findings indicate homophily’s role in influencing trust, content, and prestige. BE is developed through warmth and content, whereas trust and prestige inspire warmth. Further, an influencer’s popularity impacts homophily and content. Lastly, the mediating role of warmth, homophile, trust, exciting content, and prestige advances the understanding of influencers and BE.Research limitations/implicationsWe converge literature from branding, influencer marketing, and social psychology to understand consumers' facets of promoting BE on SM. This work is a primary attempt to interlink and tie these crucial research streams together.Practical implicationsThe study offers managers helpful guidance on strategically assessing influencers' traits to build BE. Additionally, recommendations for tactically assessing and engaging influencers for brands are offered.Originality/valueThis is the first study to identify influencer-related parameters contributing to BE. Secondly, we study unique drivers such as homophily, trust, and warmth, which are important yet remain unexplored as far as BE in influencer marketing is concerned. Furthermore, this study also highlights the mediating role of key constructs that possess a potential to strengthen consumer brand relationships.
