Facebook Drives Most Retail Traffic, But Pinterest Drives the Big Spenders

Any retail site knows that social media is their friend. Not only do sites like Facebook, Twitter and Pinterest have the massive user bases to drive traffic, but they also have the opportunity to drive traffic based on the trust factor. If one of your friends recommends a product (as opposed to a typical ad), you're much more likely to check it out. That's the thought behind Facebook's main advertising platform, the Sponsored Story (and why it's crushing traditional ads). But not all social media sites are created equal when it comes to driving retail traffic.
