With the Next and Previous links, it's particularly good for long scrolling forms. The primary advantage of hypertext over other media formats is that it keeps extra information in the background as an option for those who need it. This nonlinear system for accessing information lets a user quickly jump to related references, letting both novice and advanced readers get useful information from the same document. To measure the accessibility of information on a web site, an increasingly important issue for web developers and site owners, we have developed an approach to modeling web site use behavior by creating a standard web site user model called the Max Model. This model user is based on the GOMS modeling approach, but is unique to web usage patterns by incorporating new research on web site behavior and unique assumptions about a standard web site user's characteristics.
Good design can make a Web site stand out among dozens of competing sites selling similar products.
The best-designed sites keep customers coming back. After three years working with online commerce, I've noticed some common sense rules about designing the commerce interaction. The lesson is that any interface requires ongoing and devoted attention, because when users have trouble with an interface, the interface is usually to blame. The top four vertical inches of your home page are the most valuable real estate in your Web site, and should be the most dense area in your site in both visual and functional complexity. Layout for any online document is really about the design of screens of information.
