Don't use jargon. If you are offering technical expertise, include descriptions that appeal to your client base, not your peers. For example, if you are showing that you can code with PHP and AJAX, don't say "in this case, if the input field is empty (str.length==0), the function clears the content of the txtHint placeholder and exits the function." The person who needs you to work on their site will just scratch their head and say "huh?" Say, instead, "Start entering text into this field, and it will auto-complete."
The internet is the great equalizer. In business specifically, it has leveled the playing field. Anyone can start a money-making online business—anyone with a computer, that is. But here’s the thing: virtually no technical experience is needed. Today there are plenty of tools you can use to build an online business that makes the technical work a lot easier than it was in the past.
