Good website design:

• File names should ALWAYS be lowercase with NO spaces and NO special characters other than an underscore ( _ ) or dash ( - ). It is best to limit them to eight characters, but not mandatory.
• The file structure you create on your local drive should be an exact mirror of the file structure you will have on the web server.
• Lots of short pages grouped by theme or content, rather than one very long page with everything on it.
• The main page fore the site, must be index.htm or index.html.
• Limit the number of graphics.
• Keep this page as a template so that you only change the contents and the graphic, but the links remain constant. The idea is to maximize your efficiency by making interesting changes while avoiding spending a huge amount of time every time you update your index page.
• For secondary pages, if each page is in it’s own subdirectory, it is easy to clean-up and modify.
• Every subdirectory on your site MUST have an index.htm or index.html file to prevent directory browsing.
• PowerPoint projects that you convert into html should DEFINTELY be in their own subdirectories.
• Graphics should be meaningful and add to the value of the site.
