Findings – The result of this study shows that determinants considered in this study; generation of stimulus, information search and service quality have a major impact over the loyalty of the consumer which determines the consumer behavior towards the e-tourism services for travel planning purposes. Originality of the research – This is the first kind of research done over consumer behavior of youth specifically in e-tourism industry in Taiwan’s perspective and secondly as the data is collected directly from Taiwan’s youth and is empirically evaluated so we believe its results will help the organizations for making the e-tourism industry more consumer oriented in case of Taiwan.
