3. Screen Resolution
The amount of scrolling required when a viewer visits the site is extremely critical to the chances of repeat viewership. Stretch layouts that would be compatible with any resolution will be most appealing to the viewer
4. Load Time
Make sure that your load time is low. Most people won't wait more than five seconds for a web page to load. The home page must have the least load time, as viewers are usually directly taken to that page first. Minimize Graphics, Flash and scripts as they hugely increase your file size. Use Server Side Include (SSI) files wherever possible. SSI files once called from the web server reside in its cache so on subsequent requests they load faster. All pictures, animations, graphics that you plan to use on your home page should be stored in the same directory as your main HTML program file. The use of tables to align and keep content is recommended as it gives a more attractive feel. Moreover they are faster to load and are easily generated from most HTML Editors.
Options for smooth navigation must be addressed while designing your website. This is extremely important as it ensure that viewers will stay around to visit all the features that your site offers
6. Cross browser Compatibility
Make sure you check your site for compatibility with all the major internet browsers like Internet Explorer 5+, Mozilla Firefox 1.0, Opera 7.0 and Netscape Navigator 6+
These and many more will help you to bring about an effective design for your website
