Make sure all graphical navigation is clear and readable. If icons are used, make sure people can figure out what they stand for. Fonts should be clear and a reasonable size for screen viewing.

Basic screen design is broken up into four sections. Secondary navigation should be placed at the bottom of the page. After users read through the content, they will need additional navigation to avoid having to scroll to the top of the page to get to another section. All navigation, regardless of the kind, should be consistently located so users become familiar and dependent upon it. This will also help to create a consistent character or look and feel for the site.
