Given the tremendous impact of online reviews on consumer choice, responding to online word of mouth (WOM) has become an important channel for firms to engage the consumers. This thesis investigates how firms can proactively respond to online product reviews to engage customers and manage customer relationships. In Study One, based upon the data of hotel reviews on Tripadvisor.com, I propose that responding by firms differ in three aspects, namely frequency, speed, and the amount of information, and these metrics exert significant influence on subsequent consumes’ WOM engagement, hotel rankings, and votes of usefulness of the reviews. Moreover, in contrast to responding to positive reviews, responding to negative reviews greatly affects consumption decisions given the negativity bias among consumers. Thus, the subsequent two studies examine whether responding help to alleviate the detrimental impact of negative reviews. Drawing from the literature on crisis management, service failure recovery, Study Two posits that sellers’ responses to negative WOM can be categorized as defensive and accommodative. Further, whether accommodative or defensive responding is more effective depends upon the nature of NWOM, namely regular NWOM or product failure. Based on the results of a between-subject experiment, Study Two provides evidence for the asymmetric impact of accommodative versus defensive responding. When confronting regular NWOM, defensive response outperforms accommodative response or no response, whereas accommodative response is superior to defensive response or no response when coping with a service failure. Further, based on the attribution of negative reviews, a moderated mediation effect is found. To enhance the external validity and robustness of these findings, Study Three provides econometric evidence that the relative effectiveness of accommodative vs defensive response on subsequent consumers’ evaluation of their consumption experience. Upon analyzing the hotels’ responses on Tripadvisor.com, responding can be a double-edged sword in that it works only when seller takes the appropriate responding strategies. In particular, the higher proportion of accommodative responses (defensive responses) for product failure reviews (regular negative reviews), the higher the subsequent consumers’ satisfaction. However, responding can backfire when the proportion of defensive responses (accommodative responses) for product failure (regular negative reviews) is high. To recapitulate, this thesis identifies whether and how online responding influences consumer experiences on social media. These research findings can help firms formulate effective responding strategies to take advantage of social media’s unique ability to engage customers and improve consumer satisfaction and loyalty.

The goal of this thesis is to investigate the effects of different hotel response strategies to negative user-generated electronic word of mouth on online travel guide sites and subsequently to identify managerial implications that would lead to an effective online review management in the hotel industry. Three basic response strategies to a negative review were identified: no-response strategy, defensive response strategy and accommodating response strategy. An experimental research method with 240 respondents proved that accommodating response to a negative review has positive impact on customer's perception of a hotel. The most negative perception was observed by the defensive response strategy. The results of this experimental research were confirmed in a Mann-Whitney U-test.
