Abstract
The share of electronic commerce (e-commerce) in total commerce is increasing day by day and this affects the competition between companies. E-commerce companies should be able to hold the customer in order to increase their competitiveness. Retaining the customer is possible by ensuring customer loyalty. Therefore, the purpose of the study is determining the effects of factors that ensure customer loyalty in e-commerce companies on e-loyalty and determining the differences in customers' perceptions of loyalty factors depending on their demographic characteristics. Within the scope of the study, the attitudes of e-commerce customers about e-loyalty factors are evaluated and the effect of these factors on e-loyalty is investigated. In this context, the questionnaire prepared with 5-point Likert scale and demographic questions is presented to the participants online. Reliability and factor analysis are made to the items in the questionnaire. In order to test the hypotheses of the research, t-test, Anova, correlation and regression analyses are applied. In the findings of the study, it is observed that the majority of the participants make purchases several times a month and make these purchases mostly via mobile phones. Clothing and shoes, besides being the most preferred product groups, Trendyol.com is the most commonly preferred e-commerce website in Turkey. It is determined that e-loyalty factors (security, website design, customization, customer satisfaction) in the study have a low and medium positive effect on e-loyalty. It is observed that the customer satisfaction factor could explain 39.9% of the change on e-loyalty
