The navigation scheme you set up for your web site acts as its road map so it needs to be clear, structured and intuitive. No matter how good a site looks or how much useful information it has, if it does not have sensible navigation it will confuse visitors or drive them away. If a person has to look hard to find where they need to go, then they quickly lose focus and that is fatal to your chances of keeping them on site.

There are many ways of presenting navigation: down one side of the screen, along the top and bottom or in a frame. However, think of the search engines, as well as visitors as most search engines don't like frames or java script - which they can not be understand. As search engines need to read the links to index the site properly and you want good organic listings, java script is not a good idea and anyway some visitors will have it disabled.
