This research applies the stereotype content model and innuendo effect theory to explore the effects of micro-influencers' personality attributes, advertising appeal, and language style on spokespersons' effects of promoting affordable luxury jewelry. The results demonstrated that the hybrid personality attributes generated more positive advertising effects. In addition, micro-influencers with warm (competence) personality attributes and competence (warm) appeal, those with warm (competence) personality attributes and implicit (explicit) language style, and those with warm personality attributes, warm appeal, and implicit language style were more persuasive than those who show other combinations of personality attributes. These findings have practical implications and provide a new path for finding suitable micro-influencer spokespersons.
