In 2005, the Internet became available to one billion people worldwide with about 845 million people using it regularly (Emarketer, 2006). The United States has one of the largest Internet populations with 175.4 million online users (Weisman, 2006). It is estimated the Internet is used by 80% of advertisers and it is projected that 90% of them will adopt the Internet for advertising by 2008. Effective Web site design is essential in online advertising and in attracting and maintaining consumers’ interest. Many organizations include a Web site as part of their advertising and media mix (Arens, 2006; Geissler, Zinkham, & Watson, 2006). Web design experts assert that interface features and designs influence a site’s traffic and sales. Although there are no definite guidelines for successful Web site designs, some important constructs related to effectiveness are (1) page design, (2) navigation, (3) color usage, (4) graphics and typeface, (5) content, and (6) online advertising (Arens, 2006; Kovarik, 2002; Song & Zahedi, 2005; Van Duyne, Landay, & Hong, 2003).
