I don’t think so as only the advertiser has data you need. Let’s say sales increase but your advertiser just burns 20% of your spend because it can and you won’t know. That’s the scam part. It’s not that your spend doesn’t increase sales. It’s that part of your spend is wasted and you could increase sales more if it wasn’t scammed away as wastage. I just bought a dozen bagels for $20. I’m happy, pretty good deal. But if the store was throwing away a dozen bagels for every one I bought, that’s wastage. Just because I’m happy doesn’t mean it’s not a scam.
