Amazon Negative Keywords & Negative Targeting
The average seller wastes 28–40% of ad budget on searches that never convert. Negative keywords are how you stop the bleeding — the highest-leverage habit in all of Amazon PPC.
Negative keywords tell Amazon not to show your ad for certain searches, and negative targeting does the same for certain products. They do two jobs: cut wasted spend on irrelevant or non-converting queries, and stop your own campaigns from bidding against each other. There are two types — negative exact and negative phrase — plus negative product targeting.
01What negative keywords are and why they matter
A negative keyword is a term you add to a campaign to prevent your ad from showing for it. If you sell a premium leather wallet and your ad keeps appearing for “cheap wallet” or “free wallet,” those clicks cost money and rarely convert — so you add them as negatives and the spend stops. It sounds minor. It isn’t. The average seller pours 28–40% of their ad budget into queries that never result in a sale, which makes negative keywords the single biggest efficiency lever most accounts are leaving unused.
02Negative exact vs negative phrase
Sponsored Products gives you two negative keyword match types — and choosing the right one is the whole skill:
| Type | Blocks searches that… | Use for |
|---|---|---|
| Negative exact | Match one specific term exactly (plus close variants like plurals) | Surgically killing a single known non-converting query |
| Negative phrase | Contain those words in that order, anywhere in the search | Blocking a whole theme across many queries at once |
Use negative exact when a specific search term has proven it doesn’t convert but you don’t want to block related, useful searches. Use negative phrase to wipe out an entire theme in one move — adding free as a negative phrase blocks “free wallet,” “wallet free shipping code,” and every other search containing that word. Phrase is powerful, so aim it carefully: a badly chosen negative phrase can block good traffic too.
03Negative product targeting
The same idea applies to product targeting. Negative product targeting lets you exclude specific ASINs or entire brands so your ad won’t appear on those detail pages. It’s how you stop an automatic campaign from placing your camera lens beside an incompatible camera body, or keep your ad off a brand’s pages where it never converts. If keyword negatives control what searches you show for, product negatives control what pages you show on.
04The two jobs negatives do
Negatives aren’t just for cleanup. They do two distinct jobs:
1. Cut waste. The obvious one — stop paying for searches that are irrelevant or have proven they don’t convert.
2. Route traffic between your campaigns. This is the structural one beginners miss. When you harvest a converting term into a manual exact campaign, you must add it as a negative in the auto, broad, and phrase campaigns that discovered it. Otherwise those campaigns keep bidding on the same term and compete against your own exact campaign — driving up your CPC by fighting yourself. This “negative bridge” keeps each search flowing to exactly one campaign.
05When to add a negative
Timing separates good pruning from panic. Two cases:
- Irrelevant terms — immediately. If a search is clearly wrong for your product (wrong use, wrong category, “free,” a brand you don’t carry), negate it the moment you see it. No need to wait for data; it will never convert.
- Relevant-but-underperforming terms — after data. For terms that should work but aren’t, wait for a meaningful sample before cutting. A common threshold is around 20–30+ clicks with zero sales (or spend well past your target cost-per-order with no orders). Negating on two or three clicks is how you kill terms that were just unlucky.
You find all of these in the search-term report, which is the subject of its own lesson.
06Campaign level vs ad group level
You can add negatives at two levels. Campaign-level negatives apply across every ad group in the campaign — use these for universal blocks like “free” or an irrelevant category term. Ad-group-level negatives apply only within one ad group — use these for the surgical routing work, like negating a harvested exact keyword in just the broad ad group that surfaced it. Matching the level to the intent keeps your structure clean.
07Don’t over-negate
Negatives are powerful enough to hurt you. Block too aggressively and you strangle discovery — an auto campaign smothered in negatives stops finding the new, conversational searches that are so valuable in 2026. The goal isn’t the longest negative list; it’s the right one. Cut proven waste and route your own traffic, but leave enough room for your discovery campaigns to keep doing their job.
08A simple weekly routine
Turn this into a habit and your account stays lean automatically:
- Open the search-term report for the last 1–2 weeks
- Negate clearly irrelevant terms on sight (phrase where it’s a theme)
- Flag relevant terms with 20–30+ clicks and 0 sales → negate
- For each harvested exact winner, add it as a negative upstream
- Check high-ACoS terms — isolate or negate
- Confirm you haven’t blocked a term that later started converting
- Negatives stop wasted spend — and sellers waste 28–40% of budget without them.
- Negative exact is surgical; negative phrase blocks a whole theme; negative product excludes ASINs/brands.
- They do two jobs: cut waste, and stop your own campaigns bidding against each other.
- Negate irrelevant terms instantly; wait ~20–30+ clicks with zero sales before cutting relevant ones.
- Don’t over-negate — leave your discovery campaigns room to keep finding new terms.
Frequently asked questions
What are negative keywords on Amazon?
They’re terms you add to a campaign to stop your ad from showing for those searches. They prevent wasted spend on irrelevant or non-converting queries and keep your budget focused on traffic that actually buys.
What’s the difference between negative exact and negative phrase?
Negative exact blocks only one specific search term (and close variants), so it’s surgical. Negative phrase blocks any search containing those words in that order, so it wipes out a whole theme at once. Use exact for single terms and phrase for broad themes.
When should I add negative keywords?
Add clearly irrelevant terms immediately — they’ll never convert. For relevant terms that are underperforming, wait for a meaningful sample, commonly around 20–30 or more clicks with zero sales, before negating, so you don’t cut terms that were simply unlucky.
How many negative keywords should I have?
There’s no target number — you want the right negatives, not the most. Cut proven waste and route your own traffic, but avoid over-negating, which strangles the discovery campaigns that find new converting searches.
What is negative product targeting?
It excludes specific ASINs or brands so your ad won’t appear on those product pages. It’s the product-side equivalent of a negative keyword, used to avoid incompatible or poorly converting placements.
