Word-of-mouth (WOM) has been recognized as one of the most influential resources of information transmission. However, conventional WOM communication is only effective within limited social contact boundaries. The advances of information technology and the emergence of online social network sites have changed the way information is transmitted and have transcended the traditional limitations of WOM. This paper describes online interpersonal influence or electronic word of mouth (eWOM) because it plays a significant role in consumer purchase decisions.
Electronic Word of Mouth (eWOM) is a form of buzz marketing and it can become viral if the message is persuasive or funny enough. In eWOM we focus on person-to-person contacts that happen on the internet. You may think this is new but in fact it’s the oldest type of marketing we know. You come across something new, odd, funny or relevant and you tell your friends or the people you meet at the gym about your discovery.
