Designing a web site needs careful thinking and planning. The most important thing is to KNOW YOUR AUDIENCE.
Users are Scanners
A typical visitor will NOT read the entire content of your Web page! No matter how much useful information you put into a Web page, a visitor will only spend a few seconds scanning it before he/she decide whether to leave or to stay. Be sure to make your point in the very first sentence of the page! After that, try to keep the user occupied with short paragraphs, and new headers down the page.
Create a consistent navigation structure that is used by all the pages in your Web site. Don't use hyperlinks inside each paragraph, to send visitors to every page of your Web. This will destroy the feeling of a consistent navigation structure.
If you must use hyperlinks, add them to the bottom of a paragraph, or to the menu.
Sometimes developers are not aware of the fact that some pages take a long time to download.
Most visitors will leave a Web page that takes more than 7 seconds to download. Test your web pages over a low-speed modem connection. If your pages take a long time to download, consider removing graphic or multimedia content.
