How do you track which ads actually make conversions for you if you don't have a tracking pixel on the thank you page of the offer.
In other words, if I am running 3 ad groups with 2 ads each for 1 affiliate offer, I can obviously track my CTR - but if I make a sale, how do I know which ad to attribute the sale to?
