Frequently asked questions
What is ROAS?
Return On Ad Spend is the revenue you earn for every unit of currency spent on advertising. ROAS = revenue ÷ ad spend. A ROAS of 4 means you earned 4× what you spent.
What is a good ROAS?
It depends on your margins, but many businesses aim for a ROAS of 3–4 or higher. Lower-margin products need a higher ROAS to be profitable.
What is ACoS?
Advertising Cost of Sale is the inverse — ad spend as a percentage of revenue (spend ÷ revenue × 100). It’s commonly used for Amazon ads.
