Social media-based brand community becomes an important information channel strategy for marketing firms. Despite the growing academic interest in the issue, little knowledge exists on how social media-based brand community (hereafter SMBBC) could influence consumer brand evaluation. Accordingly, this study attempts to remedy the literature gap by integrating the community integration model, engagement in the OBC or SMBBC, and consumer brand evaluation to propose a conceptual model for investigating the effect of SMBBC environment on consumer brand evaluation. This study collected data from 402 respondents experienced in using SMBBC. The result revealed that SMBBC identification and company identification have a positive impact on brand engagement; whereas brand identification has a positive effect on SMBBC engagement, peer identification has a positive influence on company identification. In addition, both brand engagement and SMBBC engagement are found to benefit corporate brand equity and corporate reputation, respectively.

The purpose of this study is to offer conceptual foundations of social brand community by developing an integrated overview of the current research. Concepts from the Structuration theory are used for synthesizing the consumer behavior literature. This study attempts to find and fill the gaps between brand community and social brand community. To fill the gaps in the literature, potential research questions and future research directions are suggested. This study offers foundations to develop a conceptual model of social brand community by considering the basic concepts in the Structuration theory and critical characteristics of the social media environment.
