Ever notice how some Facebook URL's are short and specific (https://www.facebook.com/425Media) and others are very long and complicated (https://www.facebook.com/pages/Healing-Romance-and-Revolution/257326091016985)? Facebook has a feature called USERNAME. Username is a name that you can pick that makes your URL shorter. One caviaite though... you must have at least 25 fans. There are some cases where Facebook will grant you a username before you have the 25 fans, but most of the time, you will have to have 25 before you can create it.
A short Facebook URL is good for a number of reasons. There are a few reasons to get it done, but it helps a TON when marketing your Facebook page. You are able to add it to email signatures, business cards and other marketing material much easier with a shorter URL. Clean and simple always looks better.
