Use graphics judiciously. Graphics are attractive, but often overused. Too many or too large graphics slow down the communication process and frustrate users. Include only those that add value to the information you are presenting. Include useful links.
Links are what make the Web a web.
Link to useful resources both within your site and on other sites. A few briefly described, well-chosen links are often more valuable to users than long lists of links of unknown value. Avoid dead ends. Use navigation aids freely. Don't let your visitors get stuck in dead ends with no way to navigate around.
