Factors such as social media engagement, product quality, and brand trust influence consumers’ purchasing decisions.

The analysis method in this study uses quantitative primary data, and the test stages carried out are the convergent validity, discriminant validity, reliability, R-square, goodness of fit, and path coefficient tests. The data used in this study were collected using a questionnaire instrument, and the valid data collected were from 120 respondents. The sampling method in this study was non-probability sampling with a purposive sampling technique. The testing tool used was Smart PLS. The results showed that Social Media Engagement and Product Quality variables had a direct and indirect effect on Brand Trust and Purchase Decision variables. However, Brand Trust had no direct effect on the Purchasing Decision variable.
