Be simple and sober

Understand the need of your website. Unless you have some out of the box need, your site is basically, to provide information about your product/services or company. Hence your site should be easy to use and to navigate. Visitors might not spend a lot of time to know about your site functionality, so you should make your site more user-friendly. If your site has new age heavy graphics, it's difficult to load and users can't find it easy to use then you might lose valuable clients.
