This study explores the impact of the usability of E-commerce websites on user satisfaction and provides a reference for designing and assessing E-commerce websites, with the aim of improving websites usability for enterprises. This study proposes research hypotheses on the impact of the usability of E-commerce websites on user satisfaction based on Microsoft’s usability guidelines. In addition, the weighted scores and correlation analysis are used to test the hypotheses. One hundred and twenty three participants were selected for filling out questionnaires. Some countermeasures to improve E-commerce websites from the perspective of website usability are proposed in the end of this paper. The usability of web content, personalized services, and emotional states have the greatest impact on users’ satisfaction, which provides the relevant theoretical guides on usability construction of E-commerce websites.
