Hi
This is 
Purposes of link shortning:
There are several reasons to use URL shortening. Often regular unshortened links may be aesthetically unpleasing. Many web developers pass descriptive attributes in the URL to represent data hierarchies, command structures, transaction paths or session information. This can result in URLs that are hundreds of characters long and that contain complex character patterns. Such URLs are difficult to memorize, type-out or distribute. As a result, long URLs must be copied-and-pasted for reliability. Thus, short URLs may be more convenient for websites or hard copy publications, the latter often requiring that very long strings be broken into multiple lines or truncated.
On Twitter and some instant-messaging services, there is a limit to the number of characters a message can carry – however, Twitter now shortens links automatically using its own URL shortening service, so there is no need to use a separate URL shortening service just to shorten URLs in a tweet. On other such services, using a URL shortener can allow linking to web pages which would otherwise violate this constraint. Some shortening services, such as goo.gl, tinyurl.com, and bit.ly can generate URLs that are human-readable, although the resulting strings are longer than those generated by a length-optimized service. Finally, URL shortening sites provide detailed information on the clicks a link receives, which can be simpler than setting up an equally powerful server-side analytics engine, and unlike the latter, does not require any access to the server.
Now a days, url shortning is a one of the easiest online earning way by use of some advertisements in between the process.
Today, there are many websites available which pays you on the basis of clicks on those short/tiny url's through their websites as they earn from advertisers and shares a part of their revenue with their users who shortens the url's and bring clicks on the url's.
Today their are a lots of websites available which will pay you for link shortning/shrink and bring clicks on those short url's.
If you have a group of members you may earn from link shortner websites (as on the picture) also as they pay on the basis of clicks say for 1000 clicks you may earn upto $1.5 in countries like india and upto $5 in countries like USA.
