5. Social Media:
Social media has forever changed the way we do business in the 21st century. Facebook has more than 800 million active users and more than 50% of them log on every day*. The average user has 130 friends. Twitter has 106 million users, and 140 million tweets are being sent on average per day**.
Users now take cues increasingly from tastemakers and aficionados in their social media circles, linking out to pages and companies recommended by their friends, and in turn, referring their own friends. The reach of social media has brought the world to your doorstep. It would be in your best interests to gather as much of this social media data as possible, to see how it is coming in, how it converts, and optimize content around the goldmine of profile information available at your fingertips.
