Beyond Usability: Designing Web Sites for Persuasion, Emotion, and Trust

The next wave in Web site design is persuasive design, designing for persuasion, emotion, and trust. While usability is still a fundamental requirement for effective Web site design, it is no longer enough to design sites that are simply easy to navigate and understand so users can complete transactions. As business mandates for Web site design have grown more strategic, complex, and demanding of accountability, good usability has become the price of competitive entry. So, while usability is important, it is no longer the key differentiator it once was.
