Traditional celebrities can represent both types of endorsers (mega and macro) with a strong online presence but varying numbers of followers. This study conducted an online survey to determine the antecedents and consequences of endorsers' participation in marketing and communication strategies. The results of path analysis showed that brand and endorser credibility played a significant role in determining customer brand engagement and brand equity.
