I have not used any form of ppc for a while after the saga I've been through with Google
I setup my ads only just yesterday, so far I've spent a measly amount $13 for 1 promoted post and 1 like ad and i've now got 200+ likes and growing, plenty of likes on my posts, 2 new registrations to my website and my web traffic has started to climb.
So far so good from me and I give FB 2 thumbs up!
If this continues ill be using FB ads well into the future.
Just thought I would share.
