Hello, I do actually some FB ad testing and use WC and PPE ads. I can't actually tell which ads did bring me a sale. Of couse if my WC ad would do a conversation I would know it but how can I check which of my PPE ad converted? I see of course which of my PPE ad get more interactions but I can't tell if PPE1 get more interactions but 0 sales and PPE2 get less interactions but 5 sales?` Is there a way how I can check this? (Extra questions) Would you recommend WC or PPE more? Actually it feels like PPE does better because I also get engagment and friends will also see my ad?
