Grounded in Source Credibility Theory, the research employs a quantitative design, gathering responses from 270 social media users via a structured online survey. Employing Structural Equation Modeling (SEM-PLS), the analysis uncovers that while trustworthiness and attractiveness significantly sway consumer behavior, expertise surprisingly falls short of exerting measurable impact. This departure from prior emphasis on knowledge-based persuasion suggests a shifting consumer landscape—where authenticity and visual appeal resonate more than authority. Even more striking is the discovery that variations in age, gender, and social media habits do not meaningfully moderate these relationships. This uniformity underscores a broad psychological consistency in how consumers evaluate influencers. Marketers and practitioners, therefore, are encouraged to recalibrate their strategies, prioritizing emotional resonance and personal branding over technical qualifications.</p> Yosef Dema Elisabeth Vita Mutiarawati Yohanes Langgar Billy Copyright (c) 2025 Jurnal Ekonomi Perusahaan https://creativecommons.org/licenses/by-nc-sa/4.0 2025-08-21 2025-08-21 32 1 8 26 10.46806/jep.v32i1.1424 https://jurnal.kwikkiangie.ac.id/index.php/JEP/article/view/1536 <p>Product-moment correlation is often used to verify the internal structure of a construct. Despite its widespread use among undergraduate and graduate students, and its inclusion in nationally distributed textbooks, the author argues that this technique is fundamentally flawed. This study aims to explain the shortcomings of product-moment correlation. This study found that Confirmatory factor analysis (CFA) is the appropriate technic for that purpose because use only common variance, latent variable score is obtained only from its verified indicators and the researcher can check the ability of each indicator ability to explain its latent variable.</p> Bilson Simamora Copyright (c) 2025 Jurnal Ekonomi Perusahaan https://creativecommons.org/licenses/by-nc-sa/4.0 2025-08-21 2025-08-21 32 1 1 7 10.46806/jep.v32i1.1536
