The rise of beauty Websites has become an indispensable tool for people to obtain information of skin care products. A research model of maintaining a successful membership beauty website was developed based on the commitment-trust theory (CTT)of the relationship marketing paradigm. This study proposes two determinants, including the perceived site quality of Website interfaces (system-based) and investment models (person-based). The research sample consists of 409 members who had used Fashion Guide Website for more than a year. This research adopts Structural Equation Modeling (SEM) to test the proposed model and the structural model shows a good fit. The results indicated that perceived Website quality, quality of alternatives and investment size directly influenced the user’s trust, affective commitment and calculative commitment, respectively. In the indirect effects, perceived Website quality appeared to indirectly influence stickiness intentions via trust and calculative commitment. Quality of alternatives and investment size appeared to indirectly influence stickiness intentions via calculative commitment. In addition, perceived habits directly influenced stickiness intentions and also moderated the effect of trust on stickiness intentions. This study also provides conclusions and practical implications to marketers.
