The Internet, particularly the Web, has opened new vistas for businesses. The ability that anyone, using (virtually) any device could be reached anytime and anywhere presents a tremendous commercial prospective. In retrospect, the fact that almost anyone can set up a Web Application claiming to offer products and services raises the question of credibility from a consumers’ viewpoint. If not addressed, there is a potential for lost consumer confidence, thus significantly reducing the advantages and opportunities the Web as a medium offers. Establishing credibility is essential for an organization’s reputation (Gibson, 2002) and for building consumers’ trust (Kamthan, 1999). The rest of the article is organized as follows. We first provide the motivational background necessary for later discussion. This is followed by the introduction of a framework within which different types of credibility in the context of Web Applications can be systematically addressed and thereby improved. Next, challenges and directions for future research are outlined. Finally, concluding remarks are given.
