Users need to be able to find what they are looking for on your
site, and most of them want to find it quickly. If people have difficulty
navigating around your site they are likely to go elsewhere to find
what they are looking for, and they will probably not bother adding
your site to their favourites menu.
Another thing that turns many users off is finding that they have
headed of on the wrong track and then have to go back to the start
and try again. Your visitors should be able to jump to different
sections of your site without having to go back to your start page.
You may feel that you don't need to worry too much about your navigation
because you only have a small site. That may be true at the start,
but web sites tend to grow, and if you don't plan at the start,
you may get to the stage where even you have trouble finding your
way around your own site.
Make sure that you don't have any pages on your site that could
become orphaned. You can't have a page that relies on the user clicking
the back button to get back to the page that you linked it from.
If you have a page like this, somebody on another site is bound
to link to it. When this happens, the user will have no obvious
way of getting to the rest of your site.
Even if you don't have full menus on all of your pages, you should
at least have a link back to your home page on every page
in your site, except of course, your home page.
The most common way of doing this is to have your logo in the top
left corner of every page, and link it to your start page. Most
users soon get to know that clicking on the logo will jump to the
home page of the site, mainly because so many sites now use this
