Most guides on Amazon PPC negative keywords treat the decision as simple: if a search term spends money without generating a sale, add it as a negative and move on.
That advice sounds tidy, but it is also how sellers accidentally block search terms that would have converted with a little more data, a better bid, or a stronger listing.
This guide takes a different approach. Instead of only explaining what negative keywords are, it shows you how to decide whether a search term actually deserves to become one.
It also explains when to wait and where to apply the exclusion. The goal is to protect your budget without limiting future sales. The core idea behind every recommendation here is simple:
A negative keyword is not automatically a keyword that failed to generate a sale. It is a targeting decision that should be based on relevance, available performance data, campaign objectives, and business economics.
Everything in this article builds on a five-step framework by Brandock, an Amazon agency, that you can apply to any search term report:
Identify → Diagnose → Decide → Apply → Monitor
What Are Amazon PPC Negative Keywords?
Amazon PPC negative keywords are search terms or keyword targets you exclude from a campaign or ad group so your ads stop showing for those specific shopper searches. They work in Amazon Ads (Sponsored Products and, in a more limited form, Sponsored Brands) alongside your regular, positive keyword targets.
A useful way to think about it: your regular keywords tell Amazon where you want visibility. Your negative keywords, sometimes called Amazon PPC exclusion keywords or Amazon ad negative terms, tell Amazon where you specifically do not want to compete for an impression or a click.
Negative targeting exists to do one thing well: improve the quality of the traffic your ads attract. It is not primarily a way to “save money” in isolation, and it is not a substitute for good keyword research, strong listing content, or realistic bidding.
Used correctly, negative targeting redirects spend away from searches that are unlikely to convert and toward the search terms and product targets that actually drive profitable orders.
Negative Keywords vs. Regular Keywords
| Regular Keyword | Negative Keyword |
|---|---|
| Tells Amazon where you want visibility | Tells Amazon where you do not want visibility |
| Helps you discover and target shoppers | Helps you exclude unwanted or irrelevant traffic |
| Can expand reach and impressions | Refines and narrows reach |
| Requires ongoing performance monitoring to scale | Requires careful monitoring so it does not block opportunity |
Why Are Negative Keywords Important in Amazon PPC?
Negative keywords matter because Amazon’s matching logic, especially on broad and phrase match, will show your ads for search terms that are only loosely related to what you sell. Left unmanaged, that overlap quietly drains budget and muddies your campaign data.
Reduce Irrelevant and Wasteful Ad Spend
The most obvious benefit is cutting spend on searches that were never likely to convert, such as a shopper looking for a completely different product category or a competitor brand name your product has no real connection to.
Protect Budget for Higher-Value Searches
This is the more important benefit, and it is where the opportunity cost argument comes in. Amazon PPC budgets are finite.
Every dollar an irrelevant search term consumes is a dollar that was not available for a proven search term, a high-converting product target, or a new keyword you are still trying to test.
Thinking about negative keywords purely as “spend reduction” misses this. The real goal is better budget allocation, not just a lower total spend.
Improve Campaign Data Quality
Search term reports full of irrelevant clicks are harder to read. Noise from unrelated searches can distort your view of which keywords, match types, and campaigns are actually working.
Cleaning up obviously irrelevant traffic makes it easier to answer the question that matters most: which searches are genuinely capable of generating profitable results for this specific product?
Prevent Internal Campaign Overlap
When you run the same or similar keywords across multiple campaigns or match types, they can end up competing against each other for the same auction.
Negative keywords are one of the main tools used for campaign sculpting, the practice of directing specific search terms to a single, intended campaign instead of letting several campaigns bid against themselves.
Improve Budget Allocation
It is worth being precise here: negative keywords do not directly create sales. What they can do is help redirect available budget toward search terms, product targets, and campaigns that have already shown they can convert or that are still worth testing. That is a more accurate framing than claiming negatives “increase sales” on their own.
Types of Amazon PPC Negative Targeting
Amazon Ads gives you two broad ways to exclude unwanted traffic. Negative keyword targeting blocks ads based on the words a shopper searches for.
Negative product targeting blocks ads from appearing on specific product pages or product targets. Most negative keyword guides focus only on the first option. However, both targeting methods matter.
Negative Exact Match
Negative exact match blocks your ad from showing only when the shopper’s search term matches the negative keyword exactly or very close to exactly (Amazon Ads also excludes close variants of the term).
- What it blocks: the specific phrase you added, in that exact word order.
- What it does not block: longer or shorter variations that contain the phrase, or the same words in a different order.
- Best use cases: a specific, clearly irrelevant search term you have already confirmed in your search term report.
- Risks: low, since the exclusion is narrow. The trade-off is that it will not catch related variations.
Example (hypothetical): a seller of leather laptop sleeves notices the search term “laptop skin vinyl” in their report. Adding it as a negative exact match blocks that specific search without touching related terms like “leather laptop sleeve 13 inch.”
Negative Phrase Match
Negative phrase match blocks any search term that contains your negative keyword phrase, in the same word order, regardless of what comes before or after it.
- How it works: broader than negative exact, because it catches multiple variations that include the phrase.
- When it provides broader exclusion: when you have identified a whole category of irrelevant intent, such as a wrong use case or wrong product type, expressed through a recurring phrase.
- When it can accidentally block useful traffic: because the exclusion is broader, it can also block search terms you would have wanted, if the phrase happens to appear in a genuinely relevant search too.
Use negative phrases carefully because a broad exclusion can affect multiple search variations, including some you have not reviewed yet.
Negative Product Targeting
Negative product targeting excludes your ad from appearing on specific product detail pages when you are running product targeting (ASIN or category targeting) campaigns. This is covered inconsistently across most competitor guides, but it is a genuinely useful lever. Negative product targeting can help you exclude:
- Irrelevant ASINs that do not match your product category or use case
- Poor-fit competitor products where the shopper intent rarely overlaps with your offer
- Product pages that generate clicks but consistently do not convert for your listing
Negative Keywords vs. Negative ASIN Targets
| Negative Keyword | Negative Product (ASIN) Target |
|---|---|
| Excludes based on what the shopper typed | Excludes based on which product page triggered the ad |
| Used in keyword-targeted campaigns | Used in product-targeting campaigns |
| Best for irrelevant search intent | Best for irrelevant or poor-fit placements |
Do Negative Keywords Work the Same Across All Amazon Ad Types?
No. Negative keywords do not work the same way across every Amazon ad type. The options available depend on the campaign and targeting method you are using.
For example, Sponsored Products and Sponsored Brands allow you to add negative keywords to stop your ads from appearing for irrelevant customer searches. However, the match types and level of control available may differ.
With Sponsored Products, you can also use negative product targeting. This allows you to exclude specific ASINs or product categories where you do not want your ads to appear.
The main takeaway? Always check the targeting options available for each campaign type before adding negatives. A strategy that works for one Amazon ad campaign may not work in exactly the same way for another.
How Do Amazon PPC Negative Keywords Actually Work?
When a shopper searches on Amazon, the platform evaluates which campaigns and ad groups are eligible to compete for that impression based on your targeting. Negative targeting is checked as part of that process before the auction:
- Shopper enters a search term
- Amazon evaluates which of your campaigns and ad groups are eligible based on your positive targeting
- Amazon checks that search term against your negative targeting at the campaign and ad group level
- If the term is not excluded, your ad can compete in the auction
- If the term matches a negative target, your ad is excluded from that auction entirely
Exact platform behavior, including how close variants are handled and how negative targeting interacts with different campaign types, can change over time and depends on your specific campaign setup. Platform-specific functionality should be verified against current Amazon Ads documentation rather than assumed from older guides.
How to Find Negative Keywords for Amazon PPC: Brandock Negative Keyword Decision Framework
This is the section where most guides give you a list of red-flag metrics and stop. That advice is incomplete, because a metric on its own does not tell you why a search term underperformed.
Step 1: Identify Suspicious Search Terms
Start by pulling your Amazon Ads search term report and scanning for terms that fit one or more of these patterns:
- Clearly irrelevant terms with no connection to your product
- High-spend search terms with no orders
- Repeated clicks over time with no meaningful outcome
- Low-relevance search terms that only loosely match your listing
- Poor-fit product searches, where the shopper is likely looking for a different category
- Expensive search terms with weak economics relative to your product’s margin
Important: a bad metric alone does not automatically make a keyword negative. This step only creates your list of candidates. The next step decides what to do about each one.
Negative keyword decisions are really the other half of keyword research. If you have not already built a structured process for discovering and qualifying keywords, Amazon PPC keyword research explains how to find and prioritize the terms worth targeting.
This makes it easier to distinguish a genuinely irrelevant search term from one you simply have not tested properly yet.
Step 2: Diagnose Why the Search Term Performed Poorly
This is the step most competitor content skips, and it is where the real decision-making happens. For each candidate search term, work through these questions in order.
Is the search term irrelevant to what you sell?
If yes, it is a strong negative candidate. There is little to lose by excluding it, because it was never going to convert regardless of bid, listing quality, or price.
Is the search relevant, but the listing is weak for that intent?
If yes, investigate before negating. A relevant search term with poor conversion may point to a listing problem, missing keyword coverage in your title or bullets, a weak main image, or a price that does not match shopper expectations for that search, not a targeting problem.
Is the search term relevant but too expensive relative to what it returns?
If yes, consider alternatives before adding a negative:
- Lowering the bid on that specific search term or keyword
- Adjusting daypart or placement modifiers if spend is concentrated in low-value placements
- Testing a different match type to control how broadly it is triggered
- Reviewing whether the campaign structure is putting this term in the right context
Is there simply not enough data yet to judge the term fairly?
If yes, continue monitoring rather than negating. A term with a handful of clicks and no orders is not the same as a term with hundreds of clicks and no orders. Cutting off a search term before it has had a fair chance to convert is one of the most common ways sellers accidentally block future sales.
Step 3: Evaluate the Search Term Against Your Economics
Once you know a search term is relevant but underperforming, the decision usually comes down to your specific product economics rather than a universal rule. The evaluation path looks like this:
- Relevance: does the search term genuinely match shopper intent for this product?
- Clicks: how much traffic has this term generated?
- Spend: how much budget has it consumed?
- Orders: has it produced any conversions at all?
- Conversion rate: how does it compare to your other keywords in the same campaign?
- ACoS or profitability: does the resulting cost per sale fit within what this product can absorb?
The same dollar amount can mean very different things depending on the product. A $20 spend with no orders may be statistically insignificant for a $60 product with a healthy margin and steady sales velocity.
That same $20 could be a meaningful warning sign for a $12 product with thin margins.
The right decision depends on several factors. Consider the product price, profit margin, average CPC in your category, typical conversion rate, break-even ACoS, and the specific goal of the campaign.
Step 4: Choose the Right Action
Once you have diagnosed the search term, the decision is rarely limited to “add as negative.” Use the situation to guide the action:
| Situation | Possible Action |
|---|---|
| Completely irrelevant search term | Add as negative |
| Relevant but expensive | Adjust bid, review economics, or restructure targeting |
| Relevant but insufficient data | Continue monitoring |
| Relevant, converting well | Harvest into a dedicated exact-match campaign and scale |
| Poor-fit product page (product targeting) | Add a negative product target |
| Overlapping traffic across campaigns | Use campaign sculpting |
The “harvest and scale” row deserves its own note, since negative keyword work often uncovers strong performers along the way.
When a search term is consistently converting well, it is worth isolating into its own exact-match campaign and treating it as one of your platinum keywords, the small set of proven terms that typically deserve a higher bid and closer, individual monitoring.

The 5 Main Categories of Negative Keyword Candidates
Once you have applied the diagnostic questions above, most negative keyword candidates fall into one of five categories.
1. Completely Irrelevant Searches
The easiest negative decision. The shopper’s intent has no meaningful connection to your product. There is little diagnostic work needed here beyond confirming the term truly has no relevance.
2. Wrong Product Type Searches
The shopper is looking for something in a similar space but not the actual product you sell, for example, a related accessory instead of the core product, or a different product format entirely.
3. Wrong Use-Case Searches
The product may technically relate to the keyword, but it does not satisfy what the shopper is actually trying to accomplish. These are worth reviewing carefully, since the line between “wrong use case” and “underserved use case you could actually target” is not always obvious.
4. High-Spend Searches With Poor Economics
These require investigation before automatically negating, using the diagnostic questions from Step 2 above. Poor economics can come from an irrelevant term, but they can just as easily come from a relevant term with a listing problem, a bidding problem, or a temporary data gap.
5. Repeated Low-Value Search Terms
Terms that consistently consume impressions, clicks, and budget without meaningfully contributing to your campaign objectives over an extended period, even after you have already tried bid or placement adjustments.
Common Amazon Negative Keyword Examples to Start With
Some search terms are unlikely to lead to a relevant sale and can be considered for negative targeting. However, always review your campaign data before adding them, as the right negative keyword depends on your product and targeting strategy.
Common examples include:
- Free: free, free sample, giveaway
- Jobs and careers: jobs, career, salary, hiring
- Information-only searches: how to make, DIY, tutorial, recipe
- Competitor or unrelated brands: Brand names that are not relevant to your product or strategy
- Wrong product types: Search terms for products you do not sell
- Wrong sizes, materials, colors, or variations: Terms that clearly do not match your product
- Low-intent terms: Queries that repeatedly generate clicks but show no meaningful conversion potential
Low CTR, High Clicks, or High Spend: When Should You Add a Negative?
Most guides address click-through rate, click volume, and spend as separate metrics. In practice, they should be read together as part of the same decision, not in isolation.
Low CTR
A low click-through rate on its own is not a negative keyword signal, since negative keywords are about excluding traffic you are already receiving, not traffic that is not clicking. Low CTR is more often a sign of a listing or creative issue. Common causes include:
- Weak relevance between the search term and your product
- Overly broad targeting pulling in loosely related impressions
- A listing mismatch, where the main image or title does not answer the shopper’s specific search
- Highly competitive search results where your listing is being outcompeted for attention
Low CTR alone is not an automatic negative keyword signal.
High Clicks With No Orders
Work through this in order:
- Is the keyword actually relevant to the product?
- Does the listing satisfy what that specific search implies the shopper wants?
- Is there enough data to judge the term fairly, given normal conversion variability?
- Is the offer, price, and review profile competitive against what else shows up for that search?
A relevant term with high clicks and no orders often points to a listing or pricing issue rather than a targeting issue. Negating it may reduce spend in the short term without addressing the underlying reason shoppers are not converting.
High Spend With No Sales
Analyze high-spend, no-sale terms against:
- Your break-even ACoS for this specific product
- What this campaign is actually trying to achieve (for example, launch visibility versus profitability)
- The historical conversion rate for similar search terms in this campaign
- The product’s margin, since the same spend threshold means different things at different price points
Relevant but Unprofitable Search Terms
This category deserves more attention than most competitor content gives it. A search term can be genuinely relevant, well-matched to your product, and still fail to be profitable at your current bid or listing conversion rate. Before treating it as a negative, consider the fuller range of options:
- Reduce the bid on that specific term or keyword
- Isolate the search term into its own ad group or campaign for closer control
- Change the match type to reduce how broadly it is triggered
- Move it to a different campaign structure better suited to its performance level
- Continue monitoring if the data is still limited
- Negate it, if none of the above changes the underlying economics
How to Use Search Term Reports to Find Negative Keywords
Review Actual Shopper Search Terms
The keyword you are targeting and the search term a shopper actually typed are not the same thing, especially under broad and phrase match. Your Amazon Ads search term report shows the real query, and that is the only place a genuine negative keyword decision should start.
Look for Patterns, Not Just Individual Terms
Reviewing search terms one at a time is slow and easy to get wrong. It is usually more productive to look for a recurring pattern.
For example, if several poor-performing search terms share the same irrelevant modifier, such as a word describing a different size, material, or use case, that pattern is worth investigating as a potential negative phrase.
Before creating a broad exclusion, check whether that word also appears in search terms that have converted. A pattern that looks irrelevant in isolation can still show up inside genuinely valuable searches.
Group Poor Performers by Theme
Grouping underperforming search terms into themes makes the review process faster and more strategic than evaluating each term individually. Common themes include:
- Wrong audience intent
- Wrong product entirely
- Wrong material or specification
- Wrong size or variation
- Wrong use case
Use an Appropriate Data Window
Avoid rigid rules like “review after seven days” applied to every campaign. The right review window depends on:
- Overall sales volume for the product
- Traffic volume the campaign is generating
- Average cost per click in the category
- Typical conversion cycle length, since some categories involve longer research before purchase
- Product category norms
A high-traffic campaign can produce a statistically meaningful pattern in days. A lower-traffic campaign may need weeks before a search term has had a fair chance to convert.
Search Term Isolation and Campaign Sculpting
Search term isolation helps you separate high-performing queries from irrelevant or low-converting traffic, giving you greater control over where your Amazon Ads budget goes.
What Is Search Term Isolation?
Search term isolation means using negative keywords to route specific search terms toward a single, intended campaign rather than letting the same term trigger multiple campaigns at once.
Why Campaigns Sometimes Compete for Similar Traffic
It is common for sellers to run overlapping targeting across discovery, phrase, exact, branded, and defensive campaigns. Without negatives, the same shopper search can trigger more than one of your own campaigns, which can distort performance data and create unnecessary internal competition for the same auction.
How Negative Keywords Can Help Separate Campaign Types
Negative keywords are one of the main tools for keeping these campaign types cleanly separated:
- Discovery campaigns (broad match, auto targeting) used to find new search terms
- Phrase campaigns used for controlled expansion around proven terms
- Exact campaigns used for your highest-confidence, best-converting keywords
- Branded campaigns targeting your own brand terms
- Competitor or defensive campaigns targeting competitor brand and product terms
Campaign sculpting should simplify control, not create unnecessary complexity. If your negative keyword lists are becoming difficult to track across campaigns, that is a sign the structure needs simplifying, not a sign you need more negatives.
Defensive and competitor-targeting campaigns are a common source of this kind of overlap, since they intentionally sit close to branded and category search terms.
If you are running (or considering) that layer of targeting, Amazon retargeting ads cover how Sponsored Display remarketing and defensive ASIN targeting fit alongside your keyword campaigns without competing against them for the same traffic.
Where Should You Add Negative Keywords?
The right placement of negative keywords depends on how broadly you want to control traffic. Choosing between campaign-level and ad-group-level negatives can help you reduce wasted spend without blocking searches that could still drive valuable sales.
Campaign-Level Negative Keywords
Best when the exclusion should apply everywhere within that campaign, regardless of which ad group triggered it. This is common for broad, clearly irrelevant terms.
Ad Group-Level Negative Keywords
Useful when the exclusion is specific to one ad group’s products or targeting, but the same term might still be relevant elsewhere in the campaign.
How to Decide Between Campaign and Ad Group Level
| Question | Likely Level |
|---|---|
| Should this term be blocked across the entire campaign? | Campaign-level |
| Is the conflict specific to one product or ad group? | Ad group-level |
| Could the term still be valuable somewhere else in the account? | Avoid a broad exclusion until you have reviewed other campaigns |
How to Add Negative Keywords in Amazon Seller Central
The mechanical steps are straightforward. The important part is what happens before and after you click save.
- Select the campaign you want to modify.
- Choose whether the exclusion belongs at the campaign level or the ad group level.
- Open the negative targeting section for that campaign or ad group.
- Add the search term or product target you want to exclude.
- Choose negative exact match or negative phrase match, based on how broad the exclusion should be.
- Review the term one more time before saving, especially for phrase match, to confirm it will not exclude valuable variations.
- Monitor the impact over the following days and weeks rather than treating the change as finished.
That last step is easy to skip, but it is what separates a one-time cleanup from an actual negative keyword strategy.
Common Amazon PPC Negative Keyword Mistakes
Here are some of the most common mistakes sellers make when adding and managing negative keywords in Amazon PPC.
Negating a Keyword Too Early
Cutting off a relevant search term before it has accumulated enough clicks or spend to judge fairly. This is the single most common way sellers lose future sales while trying to “clean up” their account.
Using One Performance Metric in Isolation
Treating clicks, spend, or CTR as a standalone verdict. No orders yet does not automatically mean bad keyword; it may simply mean not enough data yet, or a listing issue unrelated to targeting.
Ignoring Product Economics
Applying the same spend threshold across every product in the account, without accounting for price, margin, and break-even ACoS differences between listings.
Overusing Negative Phrase Match
Using phrase match by default for convenience, which can quietly exclude valuable variations that were never actually reviewed.
Blocking Keywords That Are Valuable in Another Campaign
Adding a campaign-level negative without checking whether that same term is performing well elsewhere in the account.
Ignoring Negative Product Targeting
Focusing only on keyword-based negatives while leaving irrelevant or poor-fit product targeting placements unmanaged.
Never Reviewing Existing Negative Keywords
Treating the negative keyword list as permanent once it is built, even as the product, listing, and market conditions change.
Treating Negative Keywords as a One-Time Cleanup Task
Approaching negative targeting as something you do once during campaign setup, rather than an ongoing part of account management.
Negative keyword mistakes rarely happen in isolation. They tend to show up alongside other structural issues, like bid management, campaign structure, or budget pacing. The broader guide to Amazon PPC mistakes covers those related errors in more depth if you want a fuller account-level review.
How to Manage Negative Keywords Without Limiting Growth
Negative keyword management works best as a repeatable cycle rather than a one-time task. This lifecycle approach is what keeps a negative keyword list useful instead of becoming an outdated blocklist that quietly caps growth.
The Negative Keyword Review Cycle
Discover → Analyze → Classify → Act → Monitor → Reassess
The reassess step matters more than it might seem, because decisions that were correct when you made them can become outdated as conditions change:
- Product pricing changes, shifting break-even ACoS
- Listing quality improves, potentially changing conversion rate for a previously weak term
- Conversion rate improves over time as reviews and ranking build
- Seasonality changes shopper intent and search volume
- Campaign goals change, for example shifting from launch visibility to profitability
- Amazon’s search behavior and matching logic can evolve
How to Measure the Impact of Negative Keywords
Most competitor content stops at “negatives reduce wasted spend.” A proper evaluation looks at several metrics together over an appropriate time period:
- Wasted spend trends on the excluded terms and similar variations
- Click-through rate changes in the campaign
Conversion rate changes for the remaining search terms - Cost per click shifts as the auction composition changes
- ACoS or TACoS movement over time (see this comparison of ACoS vs. TACoS for how the two metrics differ)
- How spend is now allocated across your remaining keywords and product targets
- Overall search term quality in subsequent reports
Do not assume ACoS will immediately improve after adding negatives. Measure changes over an appropriate period and account for other campaign changes that may be happening at the same time, such as bid adjustments, budget changes, or new keyword launches.
Amazon PPC Negative Keywords Checklist
Before Adding a Negative
- Is the search term genuinely relevant to the product or not?
- Does it match the product category and use case?
- Is there enough performance data to judge it fairly?
- Have I checked this product’s specific economics (price, margin, break-even ACoS)?
- Could a bid adjustment solve the problem instead?
- Could this same term be valuable in a different campaign?
When Adding
- Correct match type selected (negative exact or negative phrase)
- Correct level chosen (campaign or ad group)
- Checked for overlapping traffic that is currently converting elsewhere
After Adding
- Monitor traffic changes in the following search term reports
- Monitor spend reallocation across the campaign
- Review overall search term quality
- Reassess the decision periodically as conditions change
Tools That Can Help Find and Manage Negative Keywords
Manual Analysis
Reviewing search term reports directly in Seller Central works well for smaller accounts with a manageable number of campaigns and a lower search term volume. It also forces a closer, more accurate read of each term, since nothing is being auto-classified for you.
Amazon Advertising Reports
Amazon’s own bulk operations and search term reports remain the best source for first-party account data, since they reflect exactly what Amazon’s system recorded.
PPC Software
Third-party PPC software is useful for automation, bulk analysis across large catalogs, pattern identification across many search terms, and ongoing monitoring once your account has grown past what manual review can reasonably cover.
Brandock’s free Amazon seller tools include calculators that can help sanity-check the profitability side of these decisions, such as break-even ACoS and margin, alongside whatever PPC software you use for the search term analysis itself.
Amazon PPC Agencies
Working with a PPC agency tends to make sense when campaigns have become complex, spend is substantial enough that mistakes are costly, or internal resources and expertise are limited relative to the account’s size.
When Should You Manage Negative Keywords Yourself vs. Hire an Amazon PPC Expert?
DIY May Work If:
- Your campaign structure is still relatively simple
- Ad spend is manageable and mistakes are low-cost to fix
- You have consistent time available to review search term reports
Expert Help May Make Sense If:
- Campaigns are complex, with multiple products, campaign types, and overlapping targeting
- Wasted spending has become significant relative to the total budget
- Internal teams do not have the time or PPC-specific expertise to run this process consistently
If you are trying to get a clearer picture of where your account currently stands before making changes, it is worth starting with a full PPC campaign audit rather than negating terms one at a time.
For sellers who would rather hand off ongoing optimization, Brandock’s Amazon PPC management services cover search term review, negative keyword strategy, and campaign structure as part of ongoing account management.
Frequently Asked Questions
There is no universal click threshold that applies to every product. The right amount of data depends on your product’s price, margin, average CPC, and typical conversion rate. A term needs enough clicks to be statistically meaningful for that specific product before a no-conversion result should be treated as a real signal.
No. A non-converting search term can still be relevant and simply need more data, a bid adjustment, or a listing improvement. Automatically negating every non-converter is one of the most common ways sellers block future sales.
Yes, if applied too broadly or too early. A negative phrase match added without checking other campaigns, or a keyword negated before it had enough data to convert, can block search terms that would have eventually produced profitable sales.
Use campaign-level negatives when the exclusion should apply everywhere in that campaign. Use ad-group-level negatives when the conflict is specific to one ad group and the same term could still be relevant to other ad groups within the same campaign.
Negative product targeting excludes your ad from appearing on specific product detail pages in product-targeting campaigns, based on the ASIN or category rather than a search term a shopper typed.
There is no fixed universal schedule. Review frequency should reflect your traffic volume, how often pricing or listing content changes, and whether seasonality or campaign goals have shifted since the negatives were added. Treat it as an ongoing part of account management, not a one-time task.
Yes. Relevance and profitability are separate questions. A search term can genuinely match shopper intent and still fail to be profitable at your current bid, price point, or listing conversion rate.
Without negative targeting, broad and phrase match campaigns will typically continue matching to loosely related and irrelevant search terms over time, which can increase wasted spend, dilute campaign data quality, and make it harder to see which keywords are genuinely driving profitable performance.
No. Negative keywords do not directly affect your organic ranking on Amazon. They only control where your paid ads can appear.
However, excluding irrelevant searches can improve ad budget allocation, which may help you focus spend on more relevant terms that generate sales. Any impact on organic performance would be indirect, not a direct result of adding negative keywords.
The Bottom Line on Amazon PPC Negative Keywords
Amazon PPC negative keywords are a targeting decision, not an automatic reaction to a metric.
The sellers who get the most value from negative targeting diagnose the problem before making a decision. They first determine whether a search term is irrelevant, under-optimized, under-priced, or simply still collecting data.
Only then do they decide whether adding it as a negative keyword is actually the right move.
If your search term reports show irrelevant traffic across several campaigns, a structured review can help. It can also help if you are unsure whether your current negative keyword list is reducing wasted spend or quietly limiting growth.
