The Best Social Channels to Use for B-to-B Marketing

I really like to use ShortStack for this, and of course it drinks its own kool-aid and conducts lead gen on its Facebook page. ShortStack uses its Facebook cover photo to immediately draw attention to the helpful resources it's making available for download.

In fact, it's featuring a new e-book called Beyond Contests that you can see spotlighted in the last app spot to the right of the Monthly Giveaway app.
When you click Beyond Contests you're taken to a Facebook landing page that allows you to download the e-book in exchange for your contact info. Once a visitor submits that form, he or she becomes a Facebook lead.
