Abstract. Easy accessibility of information on banking activities has enabled customers to easily compare various bank products and thereby easily switch from one bank to another, resulting in diminishing customer loyalty. This results in retail banks continually working hard to make new innovations or improve their internet banking services in order to make their bank a better choice for the customer. Previous researches have shown that customer loyalty is essential for the survival and profitability of e-commerce. We investigate whether customers' trust, satisfaction, commitment, bank reputation, and the bank's website quality predict customer e-loyalty in a survey using structured questionnaire. Ordered logistic regression analysis was used to analyse the data. The results of the study revealed that bank reputation, satisfaction, trust, and commitment have a significant and positive impact on customer e-loyalty towards internet banking in Nigeria. However, website quality has a positive but insignificant influence on customer e-loyalty towards internet banking. The result further showed that reputation is an essential factor in building customer e-loyalty.
