Shorten the URLs

Whenever you are posting any external link from any of your profiles, it is a good practice to shorten the URL of the link first. See, in Twitter, there's the character restrain, for which you should shorten the link. As for other social medias, a long URL makes the post (and hence your profile) messy. Shortening a link makes you look more professional. 

URL shortening websites, like Bitly, TinyURL and goo.gl, are free to use and takes only a moment. Do use these to your benefit.
