I have never needed to track anything else than what Google Analytics offers me, but today I have decided to go into the PPC buisness on facebook and maybe Adwords... Therefore it would be very convenient to be able to track sales from these sources. I cannot use Clickbank TIDs, 'cause I am using a landing page inbetween the PPC ads and the pitch page. Is there anything else I can do to track these sales? Anything facebook, Google or Clickbank offers? Any specific code?
