Brand microblogs have been adopted as a new approach to promote products or services and maintain relationships with consumers for companies, but literature on why consumers are willing to participate on these microblogs is still relatively limited. The purpose of this study is to examine factors affecting consumers’ participation on brand microblogs and then indicate the underlying mechanism of this process based on elaboration likelihood model (ELM), commitment–trust theory and social presence.,An online survey was conducted in China to investigate consumers who followed brand microblogs. A total of 380 valid responses were collected, and the data were analyzed by the partial least squares structural equation modeling to assess the proposed research model.,The findings show that argument quality and source credibility of a brand microblog are two important factors that enhance consumers’ community commitment and trust toward the microblog, which, in turn, promote their participation intention. In addition, social presence has a moderating effect on the relationship between trust toward brand microblog and participation.,This study extends the understanding regarding consumers’ information adoption processes in brand microblogs from both central and peripheral routes based on ELM. Besides, the role of trust in affecting consumers’ participation and community commitment in the context of brand microblog has been examined from a more detailed perspective. Finally, this paper better reveal the role of social presence in brand communities by focusing on its moderating effect on the relationship between commitment–trust and consumers’ participation. These findings can provide entrepreneurs with insights into strengthening consumers’ participation and operating their brand microblogs in the long-term.
