Web page design may seem simple these days with web page design software and online services that make it almost as easy as putting together a report with a word processor.
There are some key elements to be aware of before putting your web site together:
A good design will be usable and easily navigable. If your customers can't find their way around then all your other pages don't really matter. Navigation must be simple and consistent.
When a visitor wants to find information it must be within a couple of clicks on your site. If it takes 5 clicks to get to the right information they will give up and look elsewhere.
