Credibility in the blogosphere: A study of measurement and influence of wine blogs as an information source

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.

A positive evaluation of credibility (believability) will ultimately determine its usability for decision making.

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
