In the past few years, technology has generated a new business paradigm shift (Buhalis & Law 2008).

With such a condition, the extent of argument quality and information usefulness became necessary for the readers.Given all of the importance that has been explained above, this research focused on the e-WOM source credibility, consumer's perceived risk, argument quality, information usefulness, and consum-
