Facebook Ads: The Cheapest Traffic You'll Ever Buy
My Facebook ads experience in a nutshell: mega-targeted towards US women interested in elementary education & etc, used a seasonally appropriate image and tagline, spent $140, got 275 clicks (~$0.46), four free trial signups (pick email and password), and (unsurprisingly) no sales.  $140 of AdWords would typically get about 2.5k clicks and $300+ of sales.This was a year ago.  Every couple of months I wonder "Hmm, should I take another whack at FB?" and then I decide to do something useful with my money instead, like buying Frontierville dresses.
