I'm an offline marketer trying to learn online marketing. Been suggested with my background I should start with CPA offers. I was accepted by 2 that are recommended a lot here and had questions. I've advertised a ton with Facebook, but am I allowed to or,one CPA offers on there? If so, do you just link the ad to an external landing page for the offer? Is there anything I need to make sure of so my Facebook account doesn't have any issues?
