My toughts exactly mate! I was stunned to learn that, but i guess that it does make sense. People who browse facebook go there to get updates on their social circles and share what's happening in their lives. When they go to pinterest, they are much more in a "Buying" state of mind, because they go there to find products or things they LIKE. Starting from this fact, it goes by itself that the traffic will convert much better on Pinterest than on Facebook, even if you get less clicks in absolute numbersThis is interesting indeed! What's especially smashing is the fact that Pinterest traffic spends 60 % more than facebook traffic.
