Publication/Presentation Date



Abstract. Uncovering what drives the consumer to action is of interest to academia and industry alike, and the advent of social media has added a confounding layer to the consumer decision process. In some ways, it has changed nothing, and in other ways, it has changed everything. Information is at the heart of decision making, and blogs offer a plethora. A positive evaluation of credibility (believability) will ultimately determine its usability for decision making. Using centered resonance analysis of wine blog writers and readers focus group data, this study attempts to address the full range of blog characteristics (subsequent scale items) that can be evaluated for credibility, anchoring them to the relevant research streams of media, website, and word of mouth. Structural equation modeling of viral blog and Twitter survey data is used to test the hypothesized scale with three dimensions site, message, and source for validity and also evaluate the credibility influence on behavioral intentions as mediated by trust. Evidence suggests that the author (source) is central to credibility evaluation. The data also support the influence of wine blog credibility perceptions on trust, which leads to following wine blog recommendations and continuing to participate with the wine blog.
