URL shorteners are used to make short link of a site. URL Shorteners provides a short nice looking( ! ) link. You can share them everywhere. Twitter will give you 140 words to share something, if your link eats much word, there will not be enough place to share your thoughts. On the other hand URL shorteners are helpful because they can save a link to a specific web page even if the URL to that page changes in the future. Some URL shorteners like as Bit.ly will give you the chance to track the number of clicks your shortened link. So that you can measure your Clicks. It has also a impact on your SEO of the website. See here in Wikipedia to know more about URL shortening.
