When designing a site, content is king. You should design a site around the site's content. However, if you have great content and poor navigation, your content is useless, if users can't find it. If you have great navigation and poor content, users will leave if they can't find anything useful.
So which is more important: content or navigation?
Well, they are both equally important, for the reasons stated above. To make good navigation, focus on getting users to the content as quickly as possible, and show them other choices of content if they are not interested. Good content depends on the purpose of your site.
Writing for the Web is something all Web designers should learn. When writing for the Web, keep things short and simple. Here are some hard facts on the way users react to text written not for the Web:
The title of your site is more important than most people think. It is displayed in search engine listings, and in some peoples' Favorites or Bookmarks list. When users review search results, they scan the listed site titles. If a title is uninteresting, they will skip it. If that title is yours, then you have a lost visitor.
Let's say a visitor comes to your site (the title being "Welcome to my site! www.coolsite.com") , likes it, and bookmarks it. When they go to their bookmark list, they search and search but can not find your site. Finally he/she finds it, hidden way down at the bottom of the list, under W. What's wrong with your title?
Well, since your title started with "Welcome" it was categorized under "W". If the site title began with "The", it would be under "T". A good title for the site would be "CoolSite – A site with cool free stuff!". In the new title, users know what to expect of the site, and it would be properly categorized under "C".
