The most effective way to evaluate a website is to conduct a usability study among the people who make up your target audience. Nielsen and Loranger (2006) describe usability as “how quickly people can learn to use something, how effectively they use it, how memorable it is…and how much users like it. use it.” In other words, it's easy for someone to use your website. This assessment is based on research done by Nielsen, Loranger, and others in the field of usability research, as well as my own experiences conducting usability studies, creating prototypes, and redesigning websites.
