What is ROAS?

ROAS, or return on ad spend, is how much revenue you earn for every dollar you put into advertising. The formula is simple: ROAS = revenue from ads / ad spend. A ROAS of 4 (or 400%) means you made four dollars back for every dollar spent.

What is a good ROAS?

It depends entirely on your margins. A business with 80% gross margin can thrive at a 2x ROAS, while one at 20% margin loses money at 3x. That is why the number that actually matters is your break-even ROAS, the point where the campaign pays for itself. Work it out with the break-even ROAS calculator.

The catch with reported ROAS

The ROAS your ad platform shows is only as good as the conversions it can see, and browser pixels miss a large share of them to ad blockers and cookie limits. Your true ROAS is usually higher than the platform reports, and bidding is optimising on the incomplete number. Trakt recovers the missed conversions and reports them back, so the ROAS you optimise on is the real one. See how it works.
