ROAS
By the AdFlint research team · Last reviewed July 2026
Revenue attributed to advertising divided by the ad spend that produced it, expressed as a ratio or multiple of spend.
It compares topline revenue against media cost and ignores everything else: margin, shipping, returns, fulfillment, and the fixed cost of operating. It also inherits every weakness of the attribution feeding its numerator. The most common misreading is taking a strong platform figure as proof of profit, when the same customers may well have purchased without ever seeing the ad.
