Pinterest referral traffic is growing at an alarming rate. In fact, a recent study from Piqora found that the average visit-per-pin increased 172 percent in the first half of 2014. Moreover, the average revenue-per-pin grew by 67 percent in the same time period. This data proves that Pinterest offers many opportunities to brands who are taking advantage of the platform. Brands that haven’t established a presence on the social network, however, are seriously missing out.
