Frequently asked questions

What is a good ROAS?

It depends on margins, but a 4× ROAS (400%) is a common benchmark. Your true target is your break-even ROAS, which depends on your profit margin.

What is break-even ROAS?

It's 1 ÷ profit margin — the ROAS at which ad revenue exactly covers product cost plus ad spend. Above it you profit; below it you lose money.

What's ACoS?

Advertising Cost of Sale — ad spend as a percentage of revenue. It's the inverse view of ROAS, popular on Amazon.
