Introduction

Amazon advertising has evolved much more rapidly as a necessity for businesses and sellers wishing to leverage millions of customers through the world's largest online marketplace.

Understanding ACoS: The Basics

ACoS measures the effectiveness of your Amazon ads based on the relation between ad spend and sales.

ACoS = (Ad Spend ÷ Ad Sales) * 100

If the ACoS value is low, then it means that your campaign performs better because a smaller percentage of budget was used to produce sales.

Amazon makes campaign performance reports more readable so as to track one's ad metrics. All it takes is an ad spend divided by attributed sales multiplied by 100, which is your ACoS percentage.
