FAQ
- What's the difference between ROAS and ROI?
- ROAS only shows revenue relative to ad spend and ignores your costs. ROI is based on net profit after subtracting both cost of goods and ad spend, so it gives a far more accurate picture of real profitability.
- What counts as a good ROAS?
- It depends on your industry and margins, but many advertisers treat a ROAS around 300% as the break-even mark. If your product costs are high, it's essential to look at ROI alongside it.
