Social media has emerged as a flexible and interactive communication medium in the present digital era. Contemporary businesses use social media to achieve different communication objectives. However, using social media as a communication medium for corporate social responsibility (CSR) communication with stakeholders like, consumers is not well-explored in the existing literature. Furthermore, prior studies have also failed to consider the blend of CSR communication and social media to achieve consumer-related outcomes, for example, their loyalty and purchase likelihood. To this end, the objective of this study is to examine the relationship of the CSR communication of a bank through social media with consumer loyalty and purchase intention. The current study also proposes brand admiration as a potential mediator between this relationship. The data were collected from the banking consumers through a self-administered questionnaire in a developing economy. The data were analyzed through the structural equation modeling (SEM) technique using AMOS software. The results of the current survey confirmed that CSR communication of a bank on social media has direct and indirect, via brand admiration, relations with consumer loyalty, and purchase intentions. The outcomes of this survey will be helpful for the policymakers to understand the importance of CSR communication on social media to enhance the loyalty, and purchase intention of banking consumers.
