This study aims to investigate the influence of factors of online brand communities (OBC) on customer brand engagement (CBE). Specifically, this study examines the role of community related factors including OBC experience, community relationship investment (CRI) and self-congruity (SC) on CBE towards the brand. It examines the role of collective psychological ownership (CPO) as a mediator between antecedents of CBE. Using social exchange theory, a conceptual research model is developed and empirically tested through structural equation modelling using cross-sectional data of 251 members of online brand community. PLS-SEM was used for analysis. Results suggest that community related factors influence an individual's CBE towards the brand, which also leads to higher brand equity. Findings also reveal that CPO strengthens the relationship between community related factors and CBE. In addition, the study shows the importance of CPO in predicting CBE. This study allows marketers to navigate through OBCs and design promotion strategies by creating meaningful experiences for the members. It also provides marketers with the tools to create a framework tapping into the collective will of the community.
