I wrote a tutorial on URL parameters for tracking clicks and conversions from facebook, LinkedIn, etc. a few years ago.
The technology of URL parameters hasn’t changed at all since then so you should be able to gain a solid understanding there. It’s less than a 10 minute read.
Bonus for you: the link above has URL parameters on it so we can track clickthroughs from this specific answer on Quora.
See? You’re learning already 🙂
