Web site navigation must be easy to use and understand, otherwise people
will not return to your site. Therefore, keeping clean and simple navigation
is extremely important.
Users of your site should always know where they are. If they have to
guess, or are at all confused or frustrated, they most likely won't stay
around for long. Users should also be able to find out how to get to other
parts of your site from where they are.
When the navigation elements of your site appear on all of your pages
you have created persistent navigation. There are five elements that should
be included in persistent navigation: site id, sections, utilities, search
options, and a way back home.
Your site id or logo should show up on every page, reminding users that
they are still on your site and haven't wandered off.
Also known as primary navigation, the sections link to the different parts
of your site.
Utilities are used to help visitors with the site or to provide information
such as contact or biographical information.
Using a search box or a link to a search page is extremely useful and
important to help users who prefer searching to browsing. Search options
may be unnecessary however, if your site is small and well organized.
One of the most important parts of persistent navigation is a way to get
back to the home page. Whether you use the site id as a link back home
or some other button/link, make sure it is always visible, reassuring
users that they can always find their way back to where they began.
