This study has shown the influences of expectations toward eWOM information occurred by the outcomes of eWOM usage experience, degree of perceived perception at the time of eWOM’s informative evaluation and receiver’s response in the post-eWOM stage. Specifically, perceived performance is influenced by eWOM expectations, as well as is related to three types of receiver’s behavioral responses (additional search behavior, retransmission behavior and favorable behavior) and purchase intension. These results indicate that expectations and perceived performance of eWOM information have significant relationship with receiver’s response at the post-adoption stage of eWOM. Also, the authors assume that receiver’s responses are varied according to the degree of expectations and perceived performance. As the results, four kinds of receiver’s behavioral responses were revealed as proposed. In sum, those results suggest the importance of expectations management and perceived perception in view of receiver’s various responses as the secondary contributor for eWOM diffusions and as social supporter for the first eWOM senders.
