Abstract

This paper tries to study online word-of-mouth (WOM) effect from a holistic perspective. We associate 303 new-release books' sales data from Amazon.com, Barnesandnoble.com, with WOM data from Amazon and Barnes &Noble reviews, Google Blog Search and Twitter.com. Our empirical results show that WOM of online reviews, blogs, and tweets have orthogonal impacts on book sales indicating incremental value of different types of online WOM.
