Despite of the increasing importance and the high frequency of the action of recommending websites, marketing has not specified reasons for which a person recommends a website more than others, and the determinants of this behavior. Based on an interdisciplinary literature including Marketing, Information Systems and Knowledge Management, this thesis presents a model of website recommending behaviors. The proposed model has been validated on a sample of 776 Vietnamese web users. The results highlight the impact of utilitarian and hedonistic benefits of the website for interlocutors on the transmitter’s decision and behavior.
