How to Create a Negative Keyword List for Google Ads: A 5-Step Process
A negative keyword list tells Google Ads which searches you do not want your ads to appear for. To create a negative keyword list, review your campaign goals, inspect actual search terms, identify irrelevant themes, choose the right negative match type, and apply the list to campaigns.
What Are Negative Keywords in Google Ads?
Negative keywords are words or phrases that prevent your ads from showing for searches containing terms you want to exclude. They help separate relevant searches from queries that do not match your offer.
For example, a paid digital marketing course may not want “digital marketing jobs” or “free digital marketing course.” Adding suitable negative keywords can help prevent those searches from triggering ads.
Google Ads distinguishes between keywords and search terms. A keyword is added by the advertiser, while a search term is what a person actually enters into Google. Real search data can reveal irrelevant intent you did not anticipate.
Why Do Negative Keywords Matter in Google Ads?
Negative keywords help advertisers control irrelevant search traffic and focus campaigns on searches that better match their offer. Google recommends using the Search terms report to identify irrelevant searches and add suitable negative keywords.
A campaign can attract different intentions even when searches share a topic. A paid course may want “digital marketing course,” but not “digital marketing jobs.” The topics are related, but the user’s intent is different.
How to Find Negative Keywords
Actual Google Ads search data should be your starting point.
- Review the Search terms report: It shows searches that triggered your ads and can reveal irrelevant queries.
- Use keyword research: Look for related terms with clearly different intent, such as jobs, free resources, or used products.
- Check search suggestions and related searches: These can uncover variations you missed during initial research.
- Review previous campaign data: Consider performance data before excluding a term.
- Look for recurring intent: If several queries share one unwanted theme, consider whether a broader exclusion makes sense.
Check whether the query is genuinely irrelevant before excluding it.
How to Create a Negative Keyword List
Creating a negative keyword list involves defining unwanted intent, reviewing search terms, identifying patterns, organizing exclusions, and selecting appropriate match types.
1. Define What You Don’t Want to Advertise For
Start with the campaign goal and offer. Ask which searches indicate that someone wants something you do not sell.
For a paid course, employment searches or free resources might be poor fits. For ecommerce, repairs or used products might be irrelevant.
2. Review Your Search Terms
Examine the queries that triggered your ads. Google specifically recommends the Search terms report for finding negative keyword ideas.
| Search term | Relevant? | Action |
| digital marketing course | Yes | Keep |
| free digital marketing course | No | Consider “free” |
| digital marketing jobs | No | Consider “jobs” |
| digital marketing certification | Yes | Keep |
Identify why a search is irrelevant rather than copying every unwanted query.
3. Identify Recurring Irrelevant Themes
Look for patterns across searches, such as employment, free resources, product repair, or unrelated learning intent. A recurring theme can be more useful than treating queries separately.
4. Group Negative Keywords
Grouping keywords by theme makes lists easier to maintain across campaigns.
- Employment: jobs, careers, salary, vacancy
- Free resources: free, PDF, download, template
- Learning or research intent: tutorial, definition, how to, examples
These are not universal exclusions. A business offering free resources may want some of these terms.
5. Choose the Right Negative Match Type
Google Ads supports broad, phrase, and exact negative match types for Search campaigns, and they behave differently from positive keyword match types.
Negative broad match: Excludes searches based on the negative keyword terms. For example, free digital marketing can block searches containing those terms.
Negative phrase match: Use quotation marks when the words need to appear together in that order, such as “free digital marketing”.
Negative exact match: Use brackets to exclude a specific search, such as [free digital marketing course].
Review exclusions because a broad negative can block valuable searches.
Negative Keyword Examples
Negative keyword examples vary by business because exclusions depend on what you sell and the search intent you want to avoid.
Example 1: Digital Marketing Course
A paid course might consider “free,” “jobs,” “salary,” “internship,” or “PDF” if those searches do not match the offer.
Example 2: Ecommerce Product
An online retailer selling new products might consider “used,” “repair,” “DIY,” or “wholesale” when those searches do not represent its target customers.
Example 3: Local Service Business
A local service provider might exclude “jobs,” “careers,” “course,” “training,” or “DIY” when the campaign is designed to generate service enquiries.
Note: There is no universal negative keyword list. The right exclusions depend on your business, offer, campaign, and search intent.
How to Add a Negative Keyword List in Google Ads
Google Ads lets you create a negative keyword list and apply it to relevant campaigns. The process is:
- Sign in to Google Ads.
- Go to Keywords within the Campaigns menu.
- Open the Negative keywords tab.
- Add your negative keywords, one per line.
- Choose Save to new or existing list.
- Name and save the list.
- Apply the list to relevant campaigns.
Negative keyword lists can also be applied across multiple campaigns.
Common Negative Keyword Mistakes
Common mistakes include excluding terms without checking intent, using overly broad exclusions, and failing to review lists.
1. Adding Keywords Without Checking Intent
A word can appear in an irrelevant search and still be useful in another context. Review the complete query before excluding it.
2. Using Overly Broad Exclusions
A broad exclusion can remove relevant searches. Consider what else could contain the term.
3. Creating a Huge List and Never Reviewing It
Negative keyword management should evolve with campaign data. Search behavior can reveal new irrelevant themes.
4. Using the Same List for Every Campaign
Shared lists are useful when campaigns have the same exclusions. Different offers may need different lists.
5. Forgetting Recurring Search Themes
Repeated queries with the same unwanted intent may reveal a useful exclusion.
What We’ve Learned Through Real Google Ads Campaigns
At Cvilians, our digital marketing courses use practical campaigns to teach how paid search works in real-world situations. Our Google Ads campaign analysis also shows why negative keyword management deserves attention.
Accounts using at least one negative keyword recorded a 15% average monthly conversion rate, compared with 4% among accounts without a single negative keyword. That’s a 275% higher conversion rate among accounts using negative keywords.
This doesn’t mean adding negative keywords automatically produces a 275% improvement. Campaign type, audience, budget, keyword selection, landing pages, and other factors can affect conversion rates. However, the difference highlights why filtering irrelevant search intent should be part of ongoing Google Ads management.

Conclusion
A strong negative keyword list is not about excluding as many searches as possible. It is about filtering out the searches that do not match your offer while protecting the ones that can drive qualified traffic and conversions.
Start with your campaign goals, review actual search terms, identify recurring irrelevant intent, and choose negative match types carefully. Most importantly, keep reviewing the list as your campaign generates new data.
When negative keywords are based on real search behavior, they become an ongoing tool for improving traffic quality and controlling wasted spend.
