How to Find Negative Keywords for Amazon FBA: PPC Optimization Guide

You run Amazon ads to get sales, but many times your budget goes to clicks that do not convert. This is where negative keywords come in. In simple words, negative keywords are terms that you block so your ads do not show for the wrong searches.

If you want to learn how to find negative keywords for Amazon FBA, you need to understand one main problem first.

What Are Negative Keywords in Amazon FBA PPC

Negative keywords are specific search terms that you tell Amazon not to show your ads for. This means your ad will not appear when a shopper types those terms.

There is a clear difference between positive keywords and negative keywords. Positive keywords are the ones you target to get traffic and sales. Negative keywords are the ones you block to avoid useless traffic.

For example, if you sell premium skincare, you may target “face serum,” but you may block words like “cheap” or “DIY.” This helps your ad reach buyers, not browsers.

In Amazon PPC, negative keywords play a very important role. They help you control where your ads show. Without them, Amazon may show your ads for many unrelated searches. This reduces your efficiency and wastes your budget. The negative keyword amazon meaning is simple, but its impact is very powerful.

Why You Must Find Negative Keywords (Stop Wasted Ad Spend)

Wasted spend is one of the biggest problems in Amazon PPC. You pay for clicks, but those clicks do not lead to sales. This means your money is going out, but nothing is coming back.

Bad keywords are the main reason for this issue. These keywords bring traffic, but the intent is wrong. For example, someone searching for “free samples” is not ready to buy your product.

When your campaigns include such keywords, your ACoS increases. A high ACoS means you are spending more than you earn from ads. Over time, this reduces your profit.

In FBA, your costs are already higher because of fulfillment fees. So if your ads are not efficient, your margin becomes very low.

This is where traffic sculpting becomes important. It means you guide the right traffic to the right campaigns and block low-intent traffic. This helps you lower ACoS on Amazon and improve ROAS.
