FAQ
What is a good ROAS?
It depends on your margins, fulfillment costs, and fixed costs. A ROAS that looks 'good' can still lose money if margins are low.
How to interpret
How to use ROAS
- Use the same attribution model as your ad platform or analytics reports.
- Compare ROAS by channel, campaign, and creative to spot winners.
- Always pair ROAS with margin to avoid ‘profitable-looking’ losses.
Common pitfalls
- Mixing attribution windows (e.g., 7‑day click vs. 1‑day view).
- Ignoring returns, discounts, shipping, and payment fees.
- Counting revenue but excluding subscription churn impact.
