If you have been on Twitter for a while, you are familiar with the 140 character limit that Twitter has set forth from the very start. That’s what Twitter is all about. To express yourself and communicate with others in under 140 characters. But if you waste half or more of your character limit on a URL, you are not going to be able to say much. That’s why you should use a Twitter URL service that not only allows you to share shorter URLs but also helps you track the number of clicks and the sources for those clicks as well. Thankfully, there are lots of cool URL shortening service to choose from that let you do just that:
