Hey,
I've been testing going from FB to pay per call but haven't had much luck. Being able to target mobile i thought this would have some big opportunities...anyone have any luck?
Tried it briefly but nothing stuck. Search would be my recommendation, either Bing, Adwords, or some 2nd tier stuff.
FB ads really needs some type of call extension, that allows click to call directly from the ad.
Adwords and Bing are great places to start.
