Generally, participants did not speak favorably about corporate Web sites, especially those of drug companies. Collectively, participants identified a number of characteristics that would increase the credibility of a Web site: (1) the provider organization is known to them (experiential credibility); (2) the Web site was publicized in their doctor’s office (reputed credibility); (3) the Web site identified the sources of information, including references to medical evidence; and (4) the Web site did not include corporate advertising (Feightner et al., 1999; Quintana, Feightner, Wathen, Sangster, & Marshall, 2001).
