Abstract

This study examines the influence of unique selling proposition (USP) and value proposition (VP) on consumer preferences among Generation Z, with social media digital marketing as a mediating variable. The research employed a quantitative approach, collecting data from 100 Generation Z respondents in Medan City and analyzing them using Partial Least Squares-Structural Equation Modeling (PLS-SEM). The results indicate that the unique selling proposition and value proposition do not have a significant direct effect on consumer preference. However, social media digital marketing significantly mediates the relationship between both independent variables and consumer preference. The model explains 29.5% of the variance in consumer preferences for local brands and 18.9% for international brands, highlighting the strategic role of digital communication in shaping purchasing behavior. The study offers theoretical insight into mediated customer behavior and provides managerial implications for digital brand strategy development.
