The purpose of this study is to evaluate the effects of the influencers' perceived characteristics (informativeness, perceived ease of use, and admiration) on purchase intention and purchase behavior. The main population of this research is people who use social media and follow at least one influencer. IBM SPSS 20 and SmartPLS 3.3.3 package programs were used in the analysis. In the study, confirmatory factor analysis and Structural Equation Modeling (SEM) analysis were performed to test the relationships in the proposed research model, respectively. As a result of the structural equation modeling analysis, it was found that informativeness, perceived ease of use, and admiration have significant and positive direct effects on purchase intention. In addition, informativeness, perceived ease of use, and admiration have significant and positive indirect effects on purchase behavior. The main contribution of this study to the literature is not only to explain the effects of informativeness, perceived ease of use, and admiration on purchase intention but also to comprehensively reveal the effects of these variables on both purchase intention and purchase behavior by considering them together in the context of influencer marketing.
