Abstract—Social network sites (SNSs) have highlighted as an imperative information source for experience sharing, particularly on the subject of electronic word-of-mouth (eWOM). In existing tourism literature, several studies have pointed that eWOM is a trustable source of information among friends, relatives, families and co-workers. This paper examines eWOM in SNSs as a means for sharing tourism experience and travel information, and in turn discusses its importance in assessing business administration and marketing in tourism destination. This conceptual paper contributes to the literature by presenting the decisive role of eWOM, in tourism business, from administration aspect.
