I used Facebook to market an online campaign, wasnt too successful with it actually. But still a good learning experience.

I advertized on Facebook: Was not impressed with the amount of CTs. Not worth the money in my case, bare in mind the clientele is mostly students!
They key is to not advertise directly on facebook.. you need to advertise indirectly.. via groups, friends and apps.
I've been using facebook's marketplace listing lately to generate leads for a business I'm working, through giving away free energy drink samples. I guess it caters well to the facebook users, but not sure I'd have the same success promoting a scrap booking business .... It's all a matter of targeting your offer to your market in my opinion.
