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.
