Abstract
The rapid growth of social media has established influencer marketing as a key medium through which brands seek to shape consumer behaviour; however, despite increasing academic interest, the mechanisms through which influencer attributes affect purchasing decisions remain largely theoretical. This paper proposes a comprehensive conceptual framework that positions audience engagement as the central mediating variable linking two primary antecedents—namely, influencer credibility and content authenticity—to consumer purchase intention. Drawing on Source Credibility Theory, the Elaboration Likelihood Model (ELM), and Consumer Engagement Theory, the study develops five formal propositions that explain the pathways through which influencer marketing influences consumer behaviour. The proposed model contributes to existing literature by integrating prior research, identifying key gaps, and clearly defining core constructs, while also offering a strong conceptual foundation for future empirical validation using structural equation modelling (SEM) and partial least squares structural equation modelling (PLS-SEM) techniques.
