ACOS (Advertising Cost of Sale) — Best Amazon Agencies
Answer in brief
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 best amazon agencies, ACOS measures how efficiently advertising spend converts into sales. A lower ACOS means less spend per dollar of ad-attributed revenue. Define the target ACOS for each campaign type before evaluating agency performance — a brand awareness campaign and a defensive keyword campaign should not be measured by the same ACOS target.
