ACoS — Full Service Amazon Agency
Advertising Cost of Sale — the percentage of ad-attributed revenue spent on advertising, calculated as ad spend divided by ad revenue.
Meaning in this directory
In the context of a full service Amazon agency, ACoS measures the efficiency of individual advertising campaigns and keywords. A 25% ACoS means $0.25 was spent in advertising for every $1.00 of ad-attributed revenue. Lower ACoS indicates more efficient advertising, but an optimal ACoS depends on margin structure and growth strategy.
