Intense competition in the banking industry emphasizes the importance of implementing maximum E-Service Quality, particularly in aspects such as ease of access, platform reliability, transaction security, and service responsiveness.

A quantitative approach is applied in this research using descriptive and verificative methods. The sampling technique employs purposive sampling with 180 participants. Data is obtained through questionnaire distribution and evaluated using Partial Least Squares–Structural Equation Modeling (PLS-SEM) to test the relationships between variables. The research findings reveal that E-Service Quality has a positive and significant influence on Customer Satisfaction. Furthermore, Customer Satisfaction is proven to positively and meaningfully affect Customer Loyalty. In addition, customer satisfaction is confirmed to act as a mediator in the relationship between E-Service Quality and Customer Loyalty.
