When you need actively to track where your visitors are coming from – say because you are running several campaigns – you need to now where your visitors are coming from. No, seriously, it DOES matter. 🙂
The “normal” way to do this is to add some parameters to the URL. Like e.g. myrurl.com/?track=siminar_url 
The downside of this is that the URL then is seen as a new URL by the seach engines (Google in short). This triggers dublicate contect filters since you can basically find the same stuff on 2 or more different URLs.
One solution is to use the new canonical tag : https://webhaj.boostme.dk/canonical-tag-state-your-canonical-url/
But an easier one is to use the # (called hash or pound sign), since this is basically seen as an internal link on the same page and the seach engines therefore just ignores this!
To have Google Analytics track these you need a little hack provided by Avinash Kaushik. Use this JavaScript:
var pageTracker = _gat._getTracker("UA-12345-1"); 
// Solution for domain level only pageTracker._trackPageview(document.location.pathname + "/" + document.location.hash);
// If you have a path included in the URL as well pageTracker._trackPageview(document.location.pathname + document.location.search + "/" + document.location.hash);

 I have found this great little piece of software, which you can install on you cell phone and then if it stolen, you can track it just be sending an SMS (text message) from another phone and recieve the coordinates of your phone back. I even works when the thief have replaced the sim cards with the added bonus that you will recieve the new number and owner information along with the GPS position.
