What is ROAS?
ROAS measures ad revenue divided by ad spend, but it does not prove profit by itself.
Direct answer
ROAS stands for return on ad spend. A 3.0 ROAS means each 1 dollar of ad spend produced 3 dollars of attributed revenue, before product cost, shipping, refunds, fees, and overhead.
Why this matters
Media buyers need ROAS to compare campaigns, but operators need margin and cash-flow context before scaling.
What to check
Use this term as an operating checkpoint, not just a glossary definition.
- Compare ROAS to break-even ROAS, not to a random target.
- Check the attribution window before comparing platforms.
- Reconcile platform revenue with Shopify and finance reports.
Common mistake
A campaign can have high ROAS and still lose money if gross margin is low or refund risk is high.
FAQ
What is a good ROAS for ecommerce?
A good ROAS is above your break-even ROAS and leaves enough contribution margin for overhead and growth.
Can I use ROAS to decide budget increases?
Use ROAS as one input, then check margin, inventory, refund rate, fulfillment capacity, and whether the campaign is incremental.
Why do Meta, Google, GA4, and Shopify show different ROAS?
Each system uses different attribution rules, conversion timing, and deduplication logic. Treat them as lenses, not a single truth.
