The influence of subjective characteristics of social network sites on consumers' word-of-mouth sharing

Purpose The purpose of this paper is to examine how subjective characteristics of social network sites (SNSs) affect consumers' positive and negative word-of-mouth (WOM) sharing. Design/methodology/approach The data used for this study were obtained from an online survey with a sample size of 369 consumers. Structural equation modeling was performed to test hypotheses and examine the research questions. Findings The authors found that the perceived anonymity of an SNS is negatively correlated with its perceived interpersonal closeness of friends, and the number of friends in an SNS is positively correlated with its perceived interpersonal closeness of friends. With regard to positive WOM, the perceived anonymity of the SNS has a significant negative influence on consumers' WOM, and both perceived interpersonal closeness and the number of friends have a significant positive influence on consumers' WOM. But, in the case of negative WOM, only perceived interpersonal closeness of friends has a significant positive influence on consumers' WOM. Practical implications When attempting to promote positive WOM, marketers should choose consumers who possess the "right" subjective characteristics of SNSs (i.e. low anonymity, high interpersonal closeness of friends and a large number of friends). At the same time, marketers should monitor the emergence of consumers' negative WOM, especially those consumers who have a high level of interpersonal closeness of friends in SNSs, and respond to the content of negative WOM without delay. Originality/value This study investigates the influence that subjective characteristics of SNSs have on consumers' WOM sharing and therefore contributes to the literature on the antecedents of WOM generation and also contributes to the research that compares positive WOM with its negative counterpart.
