For those who THINK they know what a professionally designed website
is, take a tip from a professional website design company's website
design elements.

From http://www.roserockdesign.com/elements_of_a_professional_web_site.php

" Is your web site capable of providing the return on investment?

• Your web site is content driven?
  (hint: Make sure your most important content is at the top of each page.)
• Ensure there are no grammatical or spelling errors.
  (hint: Use spellcheckers and use the primary definition of the word.)
• Your site is designed to work well with search engines.
  (hint: Proper placement of keywords and phrases.)
• You've limited your graphics for faster download time.
  (hint: more content, less graphics = better search engine indexing)
• Is it well organized?
  (hint: Navigation is extremely important.)
• Do you update it frequently?
  (hint: The object is to get them to come back!)
• Are your links all working?
  (hint: Use a strong designer program.)
• Is your email address on it?
  (hint: Make sure they can contact you.)
• Is your web site accessible to everyone?
  (hint: Make your web site compliant with the American's with Disabilities Act.)
• Does your web site need to be accessible via portable devices? Do you have the appropriate coding set up for your web site?
  (hint: Examine whether people would be using devices like Palm Pilots™ to access your web site.) "

My sites tend to fulfill these elements, so, I'm not worried about design.
