Social media are increasingly becoming a strategic vehicle of modern companies’ way of communicating and interacting with consumers. Actually, social media marketing (SMM) has recently emerged as an effective two-way communication channel able to provide the sharing and exchange of information, ideas, and user-generated content in virtual environments. This is especially true for fashion brands, which are progressively creating interactive platforms such as online brand communities in order to enhance their consumer-based brand equity (CBE), interpreted as the consumers’ assessment of a company brand image, identity, and value. Scholars have widely analyzed the relationship between a company’s SMM and brand equity, thus finding a direct positive impact of the five main constructs depicting perceived SMM activities, namely entertainment, interaction, trendiness, customization, and word of mouth, on CBE. Despite this relevant scholarly interest, the consumer behavioral responses linking a company perceived SMM activities and CBE have been largely neglected. Actually, consumers’ benefits from virtual environments and online brand experience may represent significant elements marketing strategists should focus on in order to enhance a company’s brand equity. Building on the uses and gratifications theory and experiential marketing, we develop a conceptual model that unpacks such linkages, by relating SMM activities, perceived benefits of using social media, online brand experience, and CBE. Specifically, we interpret SMM activities as significant brand-related stimuli able to influence consumers’ cognitive, social interactive, personal interactive, and hedonic benefits, which in turn influence consumers’ sensory, affective, behavioral, and intellectual online experience. Moreover, we investigate the experiential responses of consumers that mostly affect a company’s brand equity, which finally impacts on consumers’ purchase intention of the fashion brand. The model is validated using structural equation modeling (SEM) on a sample of real users of online brand communities operating in the fashion industry. Our sample is composed of Millennials, which currently represent the most influential grown-digital generation of consumers. Overall, our findings shed light on consumers’ online behavioral and experiential responses to a company’s perceived SMM activities, thus proposing strategic implications for the management of brand online communities and suggesting interesting possibilities of future research on social media and fashion consumers.

New communication challenges for companies that use social media are: 1) the knowledge and control of the degree of alignment between communicated and perceived brand personality in order to measure the effectiveness of competitive positioning, and 2) the measurement of engagement among consumers who share comments about brands in online communities. Our research proposes research tools that can help fashion companies meet these challenges. In particular, we present an innovative methodological approach that combines netnography and text-mining to extract and analyze data from online communities of fashion brands.
