In recent years, social media influencers (SMIs) have brought dramatic shifts to the marketing trend. Apart from product endorsement and ad campaigns, they are increasingly hired by brands for promoting social causes including Black Lives Matter movement, COVID-19, and LGBTQ+ issues owing to their perceived authenticity and expertise (Open Influence, 2022). As such, brands promoting social causes to take ethical obligations to the society, namely, corporate social responsibility (CSR), has become an indispensable business practice (McWilliams & Siegel, 2001). Accordingly, past studies revealed that SMIs’ capability of creating authentic connection with target consumers and the fact that stakeholder awareness and authentic motives are preconditions for the success of CSR initiatives can create a synergic effect (Yang et al., 2021).
