Amazon Negative Targeting:
A Complete Guide
How to stop paying for clicks that never sell. The two match types, the steps to add negatives, the spend rule that beats raw click counts, and the mistakes we see most in client accounts.
What Is Negative Targeting on Amazon?
If you run Amazon ads, you are probably paying for clicks that will never turn into sales. It happens to most sellers. Your campaigns target the right keywords, but Amazon still shows your ad on searches and product pages that have nothing to do with what you sell, and every one of those clicks costs you money.
Negative targeting is how you stop it. It lets you tell Amazon which searches and product pages should not trigger your ad, so more of your budget goes toward shoppers who are ready to buy. In this guide we will cover what negative targeting is, the two match types, how to set it up step by step, when a search term is worth blocking, and the common mistakes to avoid. The examples and numbers here come from accounts we manage at Ecom Brainly, mostly in the pet, supplement, and home goods categories.
Negative targeting is an Amazon Advertising feature that prevents your ads from appearing on searches or product pages you choose to exclude. Instead of paying for clicks that are unlikely to convert, you tell Amazon where you do not want to show up. It works in automatic and manual Sponsored Products campaigns, as well as in Sponsored Brands and Sponsored Display.
There are two types of negative targeting, and sellers often confuse them.
Negative keywords block searches. You add a word or phrase, and your ad stops appearing when a shopper’s search contains it. For example, if you sell premium dog collars, you can add “cheap” as a negative keyword so your ad does not show for “cheap dog collar.”
Negative product targeting blocks placements. Sponsored Products and Sponsored Display ads can appear on competitor product pages, and not every page is worth showing on. With negative product targeting, you exclude specific ASINs or whole brands so your ad stops appearing next to products that are not relevant to yours.
One thing to know if you have used Google Ads: Amazon automatically includes close variants in negative matching. If you add “refurbished,” Amazon also blocks “refurbish” and “refurbishes.” If you add “cheap” as a negative exact, it also blocks the misspelling “cheep.” This makes Amazon negatives more powerful, but it also means a single negative can block more than you expect.
Where negatives stop: Negative targeting will not fix a campaign that loses money because the listing does not convert. If your traffic is relevant and still not buying, the problem is usually the listing or the price, not the search term. Negative targeting removes irrelevant traffic. It does not create demand.
Negative Exact vs Negative Phrase
Negative keywords have only two match types. There is no negative broad match. If you want a refresher on how the positive side works, our guide to Amazon Ads match types covers exact, phrase, and broad in full.
Negative exact blocks only the exact search term, plus close variants and plurals. If you add “blue collar” as a negative exact, you block “blue collar” but not “blue dog collar.” Use it when one specific search is wasting money and you want to remove it without affecting related searches.
Negative phrase blocks any search that contains your phrase in order. If you add “blue collar” as a negative phrase, you block “blue collar,” “large blue collar,” and “blue collar leather.” Use it when an entire theme is irrelevant to your product, no matter how it appears.
| Negative Exact | Negative Phrase | |
|---|---|---|
| What it blocks | The exact search only, plus plurals and misspellings | Any search containing the phrase, in order |
| Risk level | Low | Higher |
| Word limit | 10 words | 4 words |
| Best for | One specific term that wastes money | A whole theme that never fits: “free,” “used,” “for kids” |
We recommend starting with negative exact in almost every case, and using negative phrase only when you are sure a whole concept does not belong in your traffic. For a seller of dog collars, “for cats” works well as a negative phrase, because no cat-related search will buy a dog collar. But “leather” as a negative phrase would be a mistake, because “leather dog collar” is one of the highest-converting searches in that category.
This is where negative phrase often causes problems. A supplement seller might add “kids” as a negative phrase to keep a children’s vitamin search off an adult product, only to find it also blocked several converting long-tail searches, with no error to warn them. Before you add a negative phrase, check your Search Term Report and read every search it would block. When in doubt, use negative exact.
How to Add Negative Keywords in Seller Central
Here is how to add negative keywords in the ad console:
Open the Advertising menu in Seller Central and go to Campaign Manager.
Select the campaign you want to edit. To apply a negative to one ad group only, open that ad group instead.
In the left menu, click Negative targeting, then the Negative keywords tab.
Click Add negative keywords.
Choose Negative exact or Negative phrase as the match type.
Enter each keyword on its own line, then click Add and Save.
One detail most guides leave out: negatives are not instant. According to Amazon’s targeting documentation, a negative keyword can take up to 72 hours to take full effect, and Amazon recommends letting any negative run for two weeks or more before you judge the result. So if you add a negative today and still see a few impressions tomorrow, the change is working, it just has not finished processing. Do not add more negatives in a panic during that window.
To remove a negative, follow the same path, select it in the Negative keywords tab, and archive it. You cannot recover an archived negative, but you can always add the same term again, so there is no risk in cleaning up your list.
Campaign vs Ad Group Negatives
Where you add a negative matters as much as which negative you add. Amazon gives you two levels.
Campaign-level negatives apply to every ad group in the campaign. Use them for terms that are never relevant to anything in that campaign, such as competitor brands, “free,” “used,” “rental,” or wrong product categories.
Ad group-level negatives apply only to that one ad group. Use them when different ad groups sell different versions of a product and you want to keep each one matched to the right shopper.
Here is a common example. Say a campaign has two ad groups, one for the men’s version of a product and one for the women’s version. You add “women’s” as a negative in the men’s ad group and “men’s” in the women’s ad group. Now each ad group only shows for its own shopper, and the two stop competing for the same searches.
The rule is simple: use campaign level for terms that are never relevant to any product in the campaign, and ad group level for terms that are wrong for one ad group but fine for another. When you are not sure, ad group level is the safer choice because it affects less.
Do not break your campaign into too many small ad groups. When you do, each ad group gets so few sales that the data is never reliable enough to act on. We once rebuilt a supplement account that had fourteen ad groups split across nearly identical keywords, and none of them had enough sales to judge. We combined them into four, and within a month each one had enough data to work with.
Used the right way, negatives are also the cleanest way to stop your own campaigns from bidding against each other, which is the main cause of PPC cannibalization.
When to Add a Negative Keyword
The most common mistake is adding a negative too early. A term with three or four clicks and no sale has not told you anything yet. Give it time to gather real data before you judge it.
Most guides, and most articles written by AI, tell you to negate any term that gets 20 or more clicks with no sale. That rule is not wrong, but it ignores price. Twenty clicks on a $12 product and twenty clicks on a $90 product cost very different amounts of money, so a flat click count treats a cheap product and an expensive one the same way.
We use a spend-based rule instead: add a keyword as a negative once the ad spend on it passes 50% of the product’s price with no sale. Base the limit on what the product sells for, not on a fixed number of clicks. On a $30 product, you negate a term once it has spent $15 with no sale. On a $90 product, you let it spend up to $45 before you cut it. A cheap product and an expensive one each get a fair limit, and you protect your profit on both.
Amazon does suggest waiting until a term has at least 20 clicks before you judge it, which is a good way to make sure you are looking at real data and not a few random clicks. But the decision to negate should come from how much the term has spent against the product’s price, not from the cost per click count alone.
| Signal | What to Look For | Action |
|---|---|---|
| Spend over half the price | Ad spend above 50% of the product’s price, no sale | Add as negative exact |
| ACoS well above target | Around double your target, and it stays there | Negate, or lower the bid |
| Enough data to judge | At least 20 clicks, so the result is not just luck | Apply the spend rule above |
| Clearly irrelevant words | “free,” “used,” “diy,” or the wrong category | Add as negative phrase |
The spend rule already takes your margin into account most of the time, but it still helps to know your break-even ACoS. A search that looks expensive against a 25% target may be fine against a 45% break-even, and negating it would cost you sales. If you have not worked out that number, our break-even ROAS calculator does it in a few seconds.
You can also go too far. Add negatives too aggressively and your campaigns stop finding new keywords. We have seen accounts where a manager negated every term after a dozen clicks with no sale, then could not work out why the automatic campaign had gone quiet. Automatic and broad match campaigns are there to test new searches, and a little wasted spend is the price of finding your next winning keyword. Give these campaigns room, and save the strict limits for your exact-match campaigns that are already proven.

How to Find Negatives in the Search Term Report
Every negative keyword you add should come from the Search Term Report. It shows the exact searches shoppers typed before they clicked your ad, which is not the same as the keywords you chose to target. Automatic campaigns give you the most to work with here, because Amazon picks the matches itself.
Here is the process we follow. It takes only a few minutes once you are used to it.
First, sort the report by spend, from high to low. Your biggest problems are at the top, so start there instead of scrolling through hundreds of rows. Look for searches that have spent money but brought in no orders. Any term that has spent more than half your product’s price with no sale is a candidate for a negative.
Next, look for patterns. The same irrelevant word often turns up across many searches. In one home goods account, “rental” appeared in eleven different search terms, all of them wasting money, and a single negative phrase handled all of them at once.
While you are in the report, look for the winners too. You can spot the good and bad terms in the same review, and most sellers stop once they have found the bad ones. Any search that converts at or below your target ACoS is a keyword worth moving into an exact-match campaign. Move it, then add it as a negative in the original campaign so the two do not compete for the same shopper. This keeps your account organized, and it ties back to the campaign setup covered earlier. If you are building your campaigns from scratch, our guide to Amazon PPC campaign structure walks through the full setup.
How often should you review the report? Weekly for high-spend or newer accounts, and every two weeks once things are stable. Search behavior changes over time, and a negative that saved money in January can block profitable traffic by June, so the review is ongoing.
Negative Product Targeting
Keywords are only half of negative targeting. The other half is controlling where your ad appears.
Sponsored Products and Sponsored Display both place ads on competitor product pages. That is useful when the page is relevant and wasteful when it is not. Amazon’s documentation gives a clear example: you advertise a camera lens, your ad appears on a page for a camera body it does not fit, and you pay for clicks that cannot convert because the products are not compatible. Adding that ASIN as a negative product target stops the waste.
To find and block wasteful ASINs:
Run a Search Term Report for your automatic and product-targeting campaigns over the last 30 days.
Filter for ASINs with at least 8 clicks and zero orders. Those are your candidates.
In the campaign or ad group, open Negative targeting and click the Negative product targeting tab.
Add the ASINs, or exclude a whole brand by name, then save.
We use negative ASINs in three ways. First, to block product pages that are not compatible with ours. Second, to stop showing on listings that heavily undercut our price, where the shopper has already decided to buy the cheapest option. Third, to keep our ads off our own other listings, so we are not paying to compete with ourselves.
One caution: negative ASIN lists go out of date quickly. ASINs sell out, get rebranded, or change category, so a target you set in the first quarter may be blocking a page that no longer exists by the third. Review the list every quarter. The same idea applies to broader product targeting, where what you exclude is as important as what you target.
Common Mistakes to Avoid
Most of the problems we see in client accounts come from the same short list of mistakes. Avoid these and you are already doing better than most sellers.
Adding negatives too early. A decision based on three or four clicks is a guess. Wait until you have enough data.
Over-using negative phrase match. One broad phrase can block dozens of profitable long-tail searches. You rarely see an error for it. You just notice your impressions drop. When in doubt, use negative exact.
Negating your own brand by accident. If your brand name contains a common word, a careless negative phrase can block your own branded traffic. Read every variation a phrase would block before you save it, and keep your branded and non-branded keyword strategy separate.
Only cleaning manual campaigns. Automatic campaigns produce the most irrelevant search terms because the algorithm explores broadly. They need negatives the most, and they are the ones sellers forget.
Setting and forgetting. Negatives are not permanent. Seasons change and so does how people search, so a negative that was safe last winter can block good traffic this summer. Make the review part of your routine.
Borrowing Google negative lists. Search intent on Amazon and Google are different, and a Google-built list will block the wrong terms. Build every Amazon negative from your own Amazon Search Term Report.
A few tools make this faster. We use Amazon’s bulk operations to add negatives across many campaigns at once, and tools like Helium 10 and Ad Badger can point out wasteful terms before they cost you much. No tool replaces reading the report yourself, but they save time.
Key Takeaways
Decide based on spend, not just clicks. Add a term as a negative once it has spent more than half your product’s price with no sale, and use the 20-click mark only to confirm you have enough data first. Start with negative exact, and only use negative phrase when a whole theme is clearly irrelevant, since phrase blocks more than you might expect. Use campaign-level and ad group-level negatives to keep each campaign matched to the right shopper and to stop your own campaigns from bidding against each other.
If you do one thing after reading this, open this week’s Search Term Report, sort it by spend from high to low, and find every search that has spent more than half your product’s price with no sale. Those are your first negatives, and removing them will save money before you change anything else.

Negative Targeting Questions Answered
Negative exact blocks only the precise search term, plus plurals and slight misspellings. Negative phrase blocks any search that contains your phrase in order. Use exact for one specific term, and phrase for a whole theme that never fits your product.
Negate any keyword where the ad spend has passed 50% of the product’s price with no sale. This scales with what the product sells for, so a cheap product and an expensive one are treated differently. The common “20 clicks with no sale” rule is only useful as a floor to confirm you have enough data, not as the decision itself.
Up to 72 hours to take full effect. If you still see a few impressions on a negated search the next day, the change is still processing. Let negatives run two weeks before judging the result.
Use campaign level for terms that are never relevant to any product in the campaign, such as “free,” “used,” or competitor brands. Use ad group level for finer control, such as keeping the men’s and women’s versions of a product matched to the right shopper.
Yes, more than any other campaign type. Automatic campaigns let Amazon explore broadly, which surfaces the most irrelevant searches. Without negatives, they waste budget quickly.
Yes, if you use them too aggressively. Over-broad negative phrases can block profitable long-tail searches, and adding negatives too early stops your automatic campaigns from finding new keywords. Start with negative exact and wait until you have enough data.
Yes. That is negative product targeting. Filter your Search Term Report for ASINs with clicks and no orders, then add them in the Negative product targeting tab, or exclude a whole competitor brand by name.
