← Back to How to Lower ACoS on Amazon Using Negative Targeting

Quick answer

Negative keyword targeting is a method used in Amazon Ads to prevent your ads from appearing for irrelevant or poor-performing search terms. By identifying and excluding these keywords, sellers can stop wasted spend and improve advertising cost of sales (ACoS). This technique is an effective way to focus your budget on the search terms that are actually bringing in sales, contributing to more efficient and profitable campaigns.

Curious whether negative keyword targeting can make a meaningful difference in your Amazon ad performance? Excluding low-value keywords is a smart way to ensure your ads run only where they’re most likely to deliver results, helping you get more from your ad budget.

How Negative Keyword Targeting Impacts ACoS

Adding negative keywords to your Amazon campaigns means your ads won’t show for search terms that have a record of high spend but low sales. This directly reduces wasted ad exposure and unnecessary clicks from shoppers unlikely to convert, leading to a lower ACoS. Rather than reducing traffic overall, you’re refining your audience to those most likely to buy.

Identifying the Right Negative Keywords

Regular review of Amazon’s Search Term Reports helps you spot which terms aren’t performing. Look for keywords with impressions and clicks but minimal or zero sales—these are strong candidates for negative targeting. Tools such as the Amazon Negative Keyword Tool by Todoza streamline this process by highlighting wasteful search terms and letting you decide what to exclude from your campaigns.

When This Matters Most

  • Budgets are tight and wasted spend must be minimized
  • You manage multiple campaigns or marketplaces and need clarity on ad performance
  • Your account frequently accrues high click costs without corresponding increases in sales volume
