ACOS
ACOS (Advertising Cost of Sales) is Sponsored Ads spend divided by the revenue those ads directly generated, shown as a percentage. A 25% ACOS means you spent $25 in ads for every $100 of ad-driven sales. Sellers target an ACOS below their profit margin so ads stay profitable at the unit level.
