Facebook and Pinterest are already going face-to-face in the Social Media Marketing war. Is the younger Pinterest set to over throw the Social Media giant? Depending on what statistics you look at each has its own slice of the Social Media Marketing pie, but Pinterest is certainly grabbing its share of the Social Media audience.
In my opinion the smart Social Media Marketer will be focusing strongly on Pinterest with a Facebook presence to secure a strong following. Considering Facebook has Intergram in their pocket they could be doing a lot better as the new comer Pinterest surges forward in popularity. If Pinterest steps into the Ad serving arena (which it is sure to do eventually) it will certainly give Facebook something more to worry about.
Are you on Facebook and Pinterest like so many others and do you have a preference?
