A good web site MUST also be well-organized and easy to navigate. Most visitors will leave a web site if they can't get its purpose in 5 - 7 seconds.
People come to a site for information.
For this reason, it is critical that you provide interesting and well thought out content. Visitors to your web site will be more inclined to do business with you, if you have provided them with the information they came for. Bookmark web sites that have styles and tastes that are similar to yours. This helps in many ways to get people to bookmark your site and return at a later time. Make sure your web site has content, but not too wordy.
