Return on Ad Spend is a revenue ratio. Profit on Ad Spend is what you keep after cost of goods sold, fees, shipping and ad spend. Pythago shows both, per product and per campaign.
That is the difference between a campaign that looks like it works and a campaign that pays you. Once you can see both numbers, deciding where to push spend and where to pull back stops being guesswork.
Every campaign and product shows Return on Ad Spend next to Profit on Ad Spend, so you optimize on margin instead of revenue.
See which variants sell profitably and which ones only look good in aggregate — size, colour and bundle level, not just the parent product.
The same variant behaves differently per country. Compare markets so you scale where the margin holds and stop paying for the ones where it doesn't.
Each product has its own margin, so it has its own break-even target. Pythago calculates it instead of applying one blanket number to your whole catalogue.
