The entire purpose of content and social media marketing is to drive people back to your site, so that they can ultimately buy what you’re promoting. It may take some time, but eventually you turn your social media followers into site visitors, site visitors into leads and leads into sales. This is social e-commerce, and it’s a complex process. But now there’s a marketing innovation that may simplify things: Facebook Storefronts, occasionally called f-commerce. They allow you to eliminate the middleman and sell products directly from your Facebook page.
