The purpose of this paper is to investigate how social media affects US retailers’ customer-based brand equity (CBBE) which is an important indicator of brand success. The authors find strong impacts of owned and earned social media on CBBE across the board. However, they find that owned social media harms CBBE of retailers dealing in hedonic and high involvement products. Whereas owned social media helps general retailers in building CBBE, it reduces CBBE of specialty retailers.

Companies that engage in corporate activism risk taking stances that reflect the values of their management but alienate key segments of a politically divided customer base. Our data suggests that company executives should think carefully about customers’ political affiliations and likelihood to engage in positive and negative word-of-mouth.

Analyzing daily data for 45 brands in 21 sectors using vector autoregression models, we find that social media brand fan following improves brand awareness, purchase intent, and customer satisfaction. Earned social media engagement volume affects brand awareness and purchase intent but not customer satisfaction, while positive and negative valence have the largest effects on customer satisfaction. Owned social media increases brand awareness and customer satisfaction but not purchase intent, highlighting a nonlinear effect of brand-controlled social media.
