Negative keywords are a powerful yet often underused element of successful par-per-click (PPC) advertising. By telling your campaigns which search queries not to target, you can protect your budget from irrelevant clicks, avoid wasted spend, and focus your ads on high-intent traffic that’s more likely to convert.
Beyond simple exclusion, negative keywords also help refine your account structure. Isolating certain terms within specific campaigns and ad groups enables you to better match ads with relevant landing pages, boosting both Quality Score and conversion rates. For example, separating branded keywords into their own campaigns gives you more control over non-branded keyword performance, helping you focus specific campaigns on acquiring new customers rather than remarketing to existing ones.

What Are Negative Keywords and Why Do They Matter?
Before diving into implementation, it’s important to understand negative keywords and how they fit into your overall PPC strategy. When used correctly, negative keywords sharpen campaign focus and ensure your ads are shown only to the most relevant audiences.
So, what are negative keywords? In PPC advertising, these are terms that you specify within your PPC campaign management tools to prevent your ads from appearing in certain search results. Unlike standard keywords that trigger your ads, negative keywords do the opposite; they block your ad from showing when the search query contains those terms.
Here’s a negative keyword example:
If you're promoting a premium software product, you might add “free” as a negative keyword to avoid clicks from users looking for free tools. This ensures your budget goes toward higher-value users who are more likely to convert.
Are you wondering how negative keywords are different from other keywords? The difference lies in intent and targeting. While regular keywords aim to match ads to relevant search queries, negative keywords help you filter out traffic that doesn’t align with your goals. Strategic use of negative keywords leads to more qualified leads, lower cost-per-click (CPC), and better campaign performance.
What’s a benefit of negative keywords? We’ll get more into the benefits but in short: improved ad relevance, better click-through-rates (CTR), and smarter spending.

How Negative Keywords Improve PPC Campaign Performance
When used strategically, negative keywords can significantly enhance campaign efficiency and lead quality. They don’t just prevent wasted spend, they help advertisers shape more targeted, higher performing campaigns that drive stronger results from the same ad budget.
Negative keywords can aid advertisers in multiple ways. For one, they can better target their ads by eliminating queries that signal low purchase intent or misaligned interests. For example, excluding terms like “jobs” or “DIY” from an ecommerce campaign ensures your ads won’t show to people searching for employment or tutorials, both of which are unlikely to convert.
One of the most immediate benefits is reduced spending on irrelevant clicks. Every impression and click matters, and filtering out unqualified traffic keeps your budget focused on the users who are most likely to buy.
Negative keywords also contribute to a higher Quality Score by making ad copy and landing pages more relevant to the search query. A well-aligned experience, from keyword to ad to landing page, tells Google your ad deserves a better placement at a lower cost.
This improved alignment also lifts your conversion rates. By narrowing targeting to high-intent searches, you funnel users toward landing pages that match their needs, cutting down on bounce rates and improving ROI.
Negative keywords help advertisers refine their strategy even further by enabling campaign segmentation. Isolating branded terms into dedicated campaigns allows for smarter budget allocation, reserving one stream for brand protection and another for new customer acquisition using non-branded keywords. This structure not only sharpens targeting but provides clearer performance insights across campaign types.
Ultimately, negative keywords can help advertisers increase PPC ROI by filtering out noise and elevating ad relevance. They serve as a tactical lever for refining audience targeting, segmenting campaigns more effectively, and channeling ad spend toward the searches that matter most.

How to Find and Add Negative Keywords
Discovering and implementing negative keywords is a continuous process, not a one-time setup. As your campaigns run and your audience behavior evolves, you’ll uncover new search terms that either waste your budget or dilute your targeting. Here’s how to stay ahead and build a high-performing negative keyword strategy.
Research Methods and Tools
Before you can find negative keywords, you need to understand where low-value queries are slipping in. For Google Ads, start with the Google Search Terms report, this reveals exactly what users typed before clicking your ads. Look for queries that generate high impressions but low engagement, or terms that don’t align with your offerings.
To streamline discovery, use a negative keyword tool or negative keyword generator like Semrush, Ahrefs, Ubersuggest, or even Google’s own Keyword Planner. These tools can highlight search variations you might not consider on your own. Another simple trick: type your core keywords into Google and pay attention to autocomplete suggestions. They often surface tangential or off-target queries you’ll want to block.
Still wondering how to identify negative keywords? Focus on signals like:
- Misaligned user intent (e.g., “careers,” “free,” “how to make”)
- Geographic mismatches
- Searches for competitors (if you're not targeting brand conquest)
- Non-commercial or research-driven queries
These insights lay the foundation for building a targeted and effective exclusion list.
How to Add Negative Keywords in Google Ads and Bing Ads
Once you’ve gathered your exclusions, the next step is knowing how to add negative keywords in the platforms you use.
In Google Ads (formerly Google Adwords), negative keywords can be added at three levels:
- Campaign level – for broad control over entire campaigns
- Ad group level – for more precise control within themes
- Account level – using shared negative keyword lists for cross-campaign management
To add negative keywords:
- Navigate to the “Keywords” tab
- Click the “Negative Keywords” section
- Choose whether to apply them at the campaign or ad group level
If you manage multiple campaigns, using shared lists ensures consistent filtering without repetitive manual updates.
Here’s a quick walkthrough:
- Go to your Google Ads dashboard
- Click “Keywords” > “Negative Keywords”
- Select “Add” and choose your level (campaign/ad group)
- Paste your terms or upload via .CSV
- Apply or link a shared list if available
The process is similar in Bing Ads, with additional options to apply negative keywords in bulk. Make sure to test and validate changes before rollout, especially if you’re handling large accounts or high-volume traffic.
Adding negative keywords is most effective when lists are logically grouped and regularly maintained.
Best Practices for Managing Lists Over Time
Negative keyword management doesn’t stop after setup. To truly scale performance, your negative keyword lists should evolve alongside your campaigns.
- Start by grouping terms into themes, such as “free,” “career/job seekers,” “DIY,” or “competitor names.” This makes it easier to add negative keywords to all campaigns as needed and ensures your filters align with campaign goals.
- Build a comprehensive list of negative keywords that you revisit regularly. Google’s search behavior changes, and your audience might too. Continuously monitor the Search Terms report to spot new low-quality queries, especially after launching new ads or promotions.
- Every few weeks, audit and refine your lists to avoid over-filtering. You don’t want to accidentally block out valuable traffic by being too aggressive. Use account-wide lists where possible but tailor them at the campaign level for precision.
Don’t forget to use clear naming conventions for shared lists, such as “Brand-Free Terms” or “Non-Buyer Phrases – Q3” to stay organized and avoid duplicate efforts.
Examples of Negative Keyword Use Cases
Let’s take a closer look at specific examples across various industries to see how negative keywords can be applied effectively. Whether you’re running a Google Ads campaign or managing Amazon PPC, the right exclusions can drive better results and minimize wasted spend.
Here are some examples of negative keywords tailored to common business types:
Ecommerce
Online retailers often face budget-draining traffic from bargain hunters or irrelevant searches. One of the best keywords to block is “cheap” if your brand emphasizes quality or premium pricing. You might also add “used” or “free shipping” if those don't align with your product offerings.
Negative keywords example:
- “cheap [product name]”
- “used [brand]”
- “how to make [product]” (for DIY queries)
Local Services
Businesses offering location-specific services need to be extra careful with keyword geography. If you operate only in Chicago, for example, consider blocking other major city names to avoid impressions in unrelated regions. Competitor brand names can also be filtered out to avoid misdirected clicks (unless you’re deliberately targeting them).
Negative keywords example:
- “plumber New York”
- “[competitor brand] coupon”
- “service areas outside your zip code”
B2B Services
For business-to-business advertisers, excluding unqualified search intent is critical. Negative keyword research might reveal irrelevant terms like “internship,” “training,” or “free trial,” especially if your business doesn’t provide those services.
Best keywords to block:
- “internship opportunities”
- “free CRM software”
- “entry-level jobs”
Amazon Sellers
With Amazon PPC, high visibility can backfire if it’s paired with poor conversion intent. Common Amazon PPC negative keywords include search terms that attract browsers, not buyers, like “manual,” “review,” or “accessories” for a standalone product.
Amazon PPC negative keywords:
- “manual for [product]”
- “[product] review”
- “cheap [product variant]”
Proactively excluding irrelevant or low-conversion terms ensures your ads show only to the right shoppers, improving return on ad spend (ROAS) and reducing advertising cost of sales (ACoS).
Common Mistakes to Avoid with Negative Keywords
While negative keywords are essential for campaign efficiency, they can backfire if not managed carefully. Missteps can limit your reach, suppress visibility, or interfere with your campaign structure. Knowing how to use negative keywords is just as important as knowing which ones to choose.
Here are the most common pitfalls, and how to avoid them.
Overusing Negative Keywords
Adding too many exclusions, especially in the early stages of a campaign, can cause under-delivery. If your ads aren’t being shown, check whether your negative keyword list is over-filtering important search variations.
Applying Negatives Too Broadly
It’s tempting to apply exclusions across your entire account, but that approach can lead to issues. Different campaigns have different goals, and what’s irrelevant in one may be useful in another. Avoid bulk applying terms unless they truly don’t apply to any of your offerings.
Ignoring Match Types
When adding negatives, many advertisers forget that negative keyword match types matter. A broad-match negative could unintentionally block valuable searches. Use phrase and exact match strategically to maintain control and avoid unintended exclusions.
Failing to Review the Search Terms Report
Negative keyword strategy is not set-and-forget. One of the biggest oversights is neglecting keyword campaigns by skipping regular audits. The Search Terms report reveals evolving search behavior, and missing those changes means you’ll keep paying for irrelevant traffic.
To truly understand how negative keywords work, it’s critical to monitor, refine, and balance exclusions based on campaign performance and user intent.

PPC Advertising and Negative Keyword FAQs
Frequently asked questions about pay-per-click advertising, Google Ads, and negative keywords.
What are negative keywords in PPC?
Negative keywords in PPC are terms you add to your campaigns to prevent your ads from showing for irrelevant or low-intent searches. Instead of triggering an ad, a negative keyword blocks it from appearing when the search query contains that word or phrase. This helps improve ad targeting, reduce wasted spend, and increase ROI.
How do I find negative keywords in Google Ads?
To find negative keywords in Google Ads, start by reviewing the Search Terms report. This report shows the actual queries that triggered your ads. Look for patterns of unrelated or unqualified traffic, such as terms related to free products, jobs, or research, and add them to your negative keyword list. You can also use keyword tools like Google Keyword Planner, Semrush, or Ahrefs for broader discovery.
What’s the difference between regular and negative keywords?
Regular keywords tell Google which searches you want your ads to appear for, while negative keywords tell Google which ones you don’t. Regular keywords trigger your ads; negative keywords block them. Using both helps fine-tune your targeting and ensures your budget is spent on the most valuable traffic.
Can negative keywords hurt my campaign?
Yes, if misused. Adding too many negative keywords, or applying them too broadly, can restrict your ad reach and cause under-delivery. For example, a poorly chosen broad match negative might accidentally block high-performing queries. Always test, review, and refine your lists carefully.
How often should I update my negative keyword list?
You should update your negative keyword list regularly, at least once or twice a month. As new campaigns launch and search trends shift, fresh irrelevant terms can start slipping through. Frequent audits of your Search Terms report will help you catch and eliminate these before they affect performance.
What tools are best for negative keyword research?
Some of the best tools for negative keyword research include:
- Google Ads Search Terms report
- Google Keyword Planner
- Semrush
- Ahrefs
- Ubersuggest
- Autocomplete suggestions in Google search
These tools help you identify search trends, filter out low-intent queries, and build smarter keyword targeting strategies.
