Authority
Authority is the credibility of the author, which refers to the extent to which an author is known and verified. The credibility of the author should be easily identified in the blog (Tillman, 2003). The authority of the author’s assessment indicators that should be clearly indicated are shown in Table 3. In fact, disclosing authors’ identities and motivations can enhance authority (Gunter; et al., 2008), raising the quality of blogs. Subsequently, a high-authority author produces high quality content (Chai, Potdar; & Dillon, 2009).
