Facebook has made things a little difficult for marketers. First, there was free earned media. Then there were paid ads as a way to attract and engage millions of followers. But now they've created restricted access. Facebook has systematically reduced access to a brand's fanbase back in 2012. That's when they restricted a brand's organic reach to about 16 percent. And in 2013, the restricted it even more. A recent study shows that around 2% of a brand's fanbase actually see brands posts. A lot of marketers assume that brand reach will soon be down to zero.
