ROAS (Return On Ad Spend)

ROAS = revenue ÷ ad spend. A ROAS of 4 means every $1 of spend returns $4 of revenue.

ROAS ignores margin, so a high-ROAS low-margin product can be worse than a lower-ROAS high-margin one. Always pair ROAS with contribution margin.

MyAd breaks ROAS down by product category, brand, audience and campaign so you can see which slice is actually profitable.
