Social media has changed the interaction between businesses and customers. Many businesses started to utilize social media for their marketing strategy, intentionally influencing consumer-to-consumer communications. The purpose of this article is to examine the effect of social media marketing on motivating Facebook users to spread electronic word-of-mouth (eWOM) and make decisions. We used a content analysis to survey 513 posts from a Facebook fan page of Yilan International Children's Folklore & Folkgame Festivel (YICFFF) and conducted poisson regression to test our hypotheses. The findings show that businesses provide brand post characteristics of brand centrality and interactivity could enhance eWOM and attention of Facebook users; brand post characteristics of information and entertainment could enhance interest, desire and action of Facebook users. Specifically, brand sentiment partially mediates brand post characteristics of brand centrality and interactivity on the number of likes, the number of comments, attention, interest, desire and action of Facebook users. Discussions and implications for the marketer are presented at the end of the article.
