First, a word of caution for Jakob Nielsen ( http://www.useit.com/jakob/ ) followers. If you are the guy who laps up every word of Alertbox http://www.useit.com/alertbox/subscribe.html ), you probably are better off exiting this page now. You'd probably find this article a little hard to digest. No, I'm not one of those Jakob bashers. I'm not a Jakob lover either. I take for what it's worth. I believe his views are like a curate's egg. Some good in parts, the others awfully bad. And I mince no bones in letting you know my opinion. So like me, I suggest you take it for what its worth. No more, no less.
In one of his Alertbox columns, web usability "Guru" Jakob Nielsen asks the question, "Is navigation useful?" http://www.useit.com/alertbox/20000109.html ) In other words, does a "menu" of some kind make sense for web users? Boy, what a question! That's like asking a new visitor to Manhattan, "Is a road map useful ?!"
I do believe a lot in Nielsen's points. But sometimes he goes overboard with some truly outstanding flaws. For one, Nielsen says: "do not link to all sections of the site from all pages". Why not Mr.Nielsen ? Why not show users what's on the site? Won't this be helpful for the surfer to navigate through easily ? Of course! Nielsen backs up his argument with a ridiculous example: "what is the probability that a user will go from looking at hairdryers to looking at grunge music?" Not likely, admittedly, but few websites offer such a choice. A more reasonable example: what is the probability that a user will go from looking at "hardware" to "software" or "support" or "contact information"? A better one , I would say.
How users get around websites
Hey, I'm not an Usability "Expert" or the omniscient "Guru". But I do
understand that users can arrive at any page within a website by a number of
means: a link, a search engine, a directory, typing a web address directly,
and so on. There is often no way to predict how a user will end up at any
website. Therefore, web pages can't be isolated from the rest of the site if
the site is to be successful and have lots of users. Visitors need some way
of getting around the website:
A search mechanism is a must for fairly large websites, or for those that can't be assigned an easily-understood architecture (in other words, a simple site map). Many users head straight to search in order to find what they're looking for, especially if the users perceive that the website has a complex structure that is difficult to navigate.
Nielsen's own website ( http://www.useit.com ) doesn't really have good navigation. Instead, it relies mostly on well-implemented hypertext linking, and users can get around most of the website simply by clicking on links in the content. Nielsen's website gets away with basically no navigation, because Nielsen understands hypertext linking. In Nielsen's uthopian world wide web, sites wouldn't really need any navigation other than a "contact information" link on every page. In the real world wide web, sites NEED navigation. Hypertext is under used, sites aren't ultra-specific, and search is unreliable.
What is "navigation"?
Essentially, navigation can be any mechanism that constantly gives users access to certain sections of a website. It's very difficult to incorporate navigation into a paragraph of text and to use hypertext links, but it's easy to create a "menu" like the one on this site.
Why navigation is useful?
My final point
