I came across merchants which were implementing checkout processes wrongly, which resulted in transactions over cerain payment types not tracking for affiliates completely. I came across merchants working with popups on the checkout page, trying to offer prospects special offers and sending them to different carts where no tracking happens. I came across merchants putting "order-now-by-phone" phone-numbers on the thank-you page, driving away leads to a channel where to tracking happens. I wonder how you deal with those issues. And what can be done if merchants are hesitant to change that?
