Facebook advertising doesn’t work because they focus on showing you ads based on who you are, not what problem you are trying to solve.
Great post about advertising in general. What people are learning is that “targeting” and “click-throughs” aren’t nearly as important as “buying”. That’s why Google rakes in the dough: they present ads when you are ready and willing to buy. Facebook presents ads when you are stalking.
As of this writing, Facebook is trading at $29.32 — down again for the day.
