At a minimum, most conventional web pages tend to provide a back link and a home link. It's your web page, ask yourself what you want people to see the most. You can't control what people look at, but you can use some techniques to make the most important links more visible. Create a menu containing links to these more imporant pages and insert it into all of your web pages. Don't be worried about using up as much as a quarter of your working area for navigational links.
Users like to be able to make choices quickly and easily.
They like to be provided with choices. And most of all, they like to have the same choices provided to them at every bend in the road. If they get lost, confused, or annoyed they'll probably head straight for the URL bar and leave your page behind. If you've been designing web pages for a while, you may remember a time only one or two years ago when you were forced to design for users with different versions of popular web browsers. You probably learned fairly quickly that when Netscape 1.0 users viewed your website they saw something completely different than what you expected.
