Growing your social media follower base is extremely important. It is advantageous to have a growing community anywhere from Facebook to Vine. The more social media 'eyeballs' you have on your product or service, the greater an impact you will make in increasing the reach of your business. In addition, you will also transition yourself in becoming a social brand to really set yourself apart from your competitors.
Another importance of having a growing community is that your follower base fits the ideal description of your target market - regardless if they are prospect or suspect.
