The aim of this study is to investigate the impact of online customer reviews and ratings on purchasing decisions. The research population consists of individuals residing in the Gempol area, with a sample size of 50, selected through purposive sampling to focus on those who have made at least two online purchases from Shopee e-commerce. This study employs an associative quantitative research approach, designed to assess the influence of the variables of online customer reviews and ratings on purchasing decisions within the Shopee e-commerce platform. Data analysis was conducted using PLS 4.0, utilizing two model types: the measurement model and the structural model. The findings indicate that online customer reviews do not significantly influence purchasing decisions, while online customer ratings exhibit a positive and significant effect on these decisions.
