ROAS
Return on ad spend: revenue attributed to ads divided by what the ads cost.
What it means in practice
A ROAS of 3 means three euros of revenue for every euro spent. It says nothing about profit: a high ROAS on a product with thin margins or many returns can still lose money. Compare it with your break-even ROAS before you scale.
