Abstract
<jats:p>This study aims to analyze the effect of store reputation on consumer purchasing decisions on the Shopee e-commerce platform, with a case study of the people of Bengkalis District. This research employed a quantitative approach with an associative research design. The sample consisted of 100 respondents selected using the Lemeshow formula and purposive sampling technique. Data were collected through questionnaires measured using a Likert scale and analyzed using validity and reliability tests, classical assumption tests, and simple linear regression analysis with the assistance of IBM SPSS Statistics. The results indicate that store reputation has a positive and significant effect on consumer purchasing decisions, as evidenced by a t-value of 3.798 and a significance level of 0.000. The coefficient of determination analysis shows an R² value of 0.128, indicating that store reputation explains 12.8% of the variation in consumer purchasing decisions, while the remaining 87.2% is influenced by other factors outside the research model. This study concludes that store reputation is an important factor in building consumer trust and encouraging purchasing decisions, particularly among the people of Bengkalis who are increasingly active in using e-commerce platforms.</jats:p>
