摘要:Internet has shaken up the tourism sector from the point of view of the consumer and of the company. Information is currently abundant and accessible; the traveler is more technological and has become an influencer. Thereby, ratings and reviews made by anonymous users on hospitality websites represent a form of influence with great impact on decision making that has transformed companies´ traditional communication models. This paper studies the mechanisms of social influence, specifically the role played by ratings and reviews in the choice of a tourist accommodation, taking into account the susceptibility of the user to the information that comes from others. An experiment was carried out. Conclusions reveal that ratings do constitute a critical factor in the decision, but are contingent upon the volume of reviews and that individual susceptibility to social influence moderated this process.
