5. Discussion and conclusion
To serve as a stepping stone to advance the theoretical knowledge of CEO-public engagement on social media, this study provides one of the earliest empirical analyses to explore how and why publics engaged with corporate executives on SNSs. It tested the conceptual model linking CEO-public engagement to important interpersonal communicative variables of perceived authenticity and approachability as well as relational outcomes of trust and satisfaction. Based on the findings, important implications for public relations scholars, professionals, and corporate leaders are discussed.
