PurposeThe purpose of this study was to discuss the importance of customer-based brand equity (CBBE) and identify the critical attributes of how to develop CBBE during the most difficult time of the COVID-19 pandemic.Design/methodology/approachThis study collected 386 restaurant managers' viewpoints to examine the mutual relationships among CBBE and other critical attributes of corporate social responsibility (CSR), electronic word of mouth (EWOM) and brand personality. Furthermore, structural equation modeling (SEM) was conducted to examine the proposed moderation and mediation hypotheses.FindingsThe results show that corporate social responsibility (CSR) mediates the relationship between brand personality and brand image. Furthermore, the mutual relationship among CBBE is discovered in that brand image may indirectly affect brand loyalty through perceived quality and brand awareness. Furthermore, with the reliance on social media, the moderating roles of electronic word of mouth (EWOM) are also revealed that strengthen the indirect effect of brand personality on brand awareness through CSR and brand image.Originality/valueWith the increasing attention to CBBE, which aims at tourism destination brand equity, hotel branding from the customer perspective, restaurant managers' viewpoints are not considered. Further, because of the impacts of the COVID-19 pandemic, customers are paying more attention to food safety and food delivery processes, which are important for CSR and connected to CBBE. However, until now, fewer studies have addressed these issues as such. The present study reflects the bidirectional effects of such a comprehensive viewpoint.
