Negative keywords are the search terms you tell Google Ads not to show your ads for. They are one of the simplest ways to cut wasted clicks, because every click you block from a job seeker, a do-it-yourselfer or someone in the wrong city is money that stays in your budget. In 2026, with broad match and automated bidding doing more of the work inside Google Ads, negative keywords are the main guardrail you still control.
This guide explains what negative keywords are, how match types work for them (they behave differently from regular keywords), where to apply them, and how to build and maintain a list that protects your budget without blocking good leads.

What Are Negative Keywords?
Negative vs. positive keywords
Positive keywords are the searches you want to appear for. If you run a painting company, "house painter" and "exterior painting near me" are positive keywords.
Negative keywords are searches you do not want to appear for. For the same company, "paint jobs hiring", "diy house painting" or "paint brush set" would be good negatives, because those searchers want a job, a tutorial or a product, not a painter.
Google Ads checks every search against your negative keywords before it decides whether to show your ad. If a search matches a negative keyword, your ad does not run for that search.
How Negative Keyword Match Types Work
You choose broad, phrase or exact match for negative keywords just like you do for regular ones, but the behavior is different, and it is where many accounts go wrong. According to Google Ads Help, negative keywords do not expand to close variants. A negative keyword for "shoe" does not automatically block "shoes", and misspellings or synonyms are not blocked unless you add them yourself.
1. Negative broad match (the default)
Your ad will not show if the search contains all of the words in your negative keyword, in any order. If the search contains only some of the words, your ad can still show.
- Negative keyword: free template
- Blocks: "free website template", "template for free"
- Does not block: "website template" (the word "free" is missing)
| Pros | Cons |
|---|---|
| Easy to set up | Does not cover synonyms or plurals |
| Catches word-order changes | Multi-word negatives can miss searches that contain only one of the words |
2. Negative phrase match
You put the negative keyword in quotation marks. Your ad will not show when the search contains those words in that order, even if there are other words before or after.
- Negative keyword: "diy kitchen"
- Blocks: "diy kitchen cabinet ideas", "best diy kitchen remodel"
- Does not block: "kitchen diy tips" (the order is different)
| Pros | Cons |
|---|---|
| More precise than broad | Order matters, so you may need variations |
| Good for blocking a specific idea | Can still block more than you intended if the phrase is short |
3. Negative exact match
You put the negative keyword in square brackets. Your ad is blocked only when the search is exactly those words with nothing added.
- Negative keyword: [paint brushes]
- Blocks: "paint brushes"
- Does not block: "buy paint brushes", "paint brushes near me"
| Pros | Cons |
|---|---|
| Safest way to avoid over-blocking | Blocks very little on its own |
| Ideal for a single bad search you spotted | Needs a lot of entries to cover many variations |
Tip: When you add a negative keyword directly from the search terms report, check the match type Google pre-selects and change it if you want to block more than that exact search.
When to Use Each Match Type
- Use negative phrase match for clear intent signals like "jobs", "salary", "diy", "how to" or "free" combined with your service. It is the workhorse of most local accounts.
- Use negative broad match for short, unambiguous words that should never trigger your ads, such as "jobs" or "careers". Be careful with single common words.
- Use negative exact match when one specific search is wasting money but similar searches are fine.
Why Negative Keywords Matter
- They protect your budget. You pay for clicks, not for conversions. Blocking irrelevant searches means more of your spend goes to people who might become customers.
- They improve relevance. When your ads appear for searches that fit your offer, click-through rate and landing page experience tend to improve, and these feed into the diagnostics Google shows you.
- They sharpen your reports. With less junk traffic, your conversion data is cleaner, which helps you and Google's bidding systems learn from the right signals.
- They counter loose matching. Broad match and automated bidding are designed to find extra searches. Some are great, and some are not. Negatives let you set boundaries.
- They lower cost per lead. For local businesses, this is the number that counts. If every wasted click is removed, the cost of each real lead drops.
Common Negative Keyword Categories for Local Businesses
Every business has its own list, but these categories are a good starting point.
- Job seekers: jobs, hiring, careers, salary, resume, apprenticeship, internship
- Do-it-yourself intent: diy, how to, tutorial, instructions, youtube, course, class, training
- Free or low-value intent: free, freebie, coupon codes if you do not offer them, cheap (only if it does not fit your positioning)
- Research only: definition, meaning, history, wiki, pdf, template, example
- Wrong products or services: terms for related services you do not offer, such as "supplies" when you provide labor
- Wrong locations: cities and states outside your service area when they appear in searches
- Competitors and brands: only if you do not want to appear for those names
Review each term carefully. A word like "cheap" is a bad search for a premium contractor but a good search for a discount service.
How to Build Your Negative Keyword List
Step 1: Brainstorm before you launch
List every reason a person might search your main keywords but never hire you. Think about jobs, free help, products, other services, and locations you do not serve.
Step 2: Use research tools
- Google Keyword Planner lists related searches for your keywords. Many of them show what you do not want.
- Google search itself. Search your main keywords and read the related searches and People Also Ask boxes to see what else people mean.
- Your own data. Past call logs, form submissions and customer emails show how real people describe their needs and what they ask for that you do not offer.
- Competitor ads. Look at how competitors word their ads. Terms they avoid are often irrelevant ones.
Step 3: Check the search terms report regularly
This is the most important habit. In Google Ads, open the search terms report and look at the actual searches that triggered your ads. Sort by cost, and look for searches with clicks and no leads. Add the clearly irrelevant ones as negatives. Note that Google may only show search terms with enough volume, so some spend will not be itemized.
- Weekly in the first month of a new campaign
- Every two weeks or monthly after that
- After any budget increase or change in keywords
Step 4: Decide the level
Google Ads lets you apply negatives at several levels:
- Ad group level for exclusions that only matter to one theme
- Campaign level for exclusions that apply to one campaign
- Shared lists for reusable lists you apply to many campaigns, such as a job-seeker list
- Account level for terms that should be blocked everywhere in your account. Check your account's available settings, as options have expanded in recent years, including negative keyword support in more campaign types.
Remember that a negative keyword at one level can block a positive keyword at another. Keep your structure simple so you can see conflicts.
A Worked Example: A Local Roofing Company
Imagine a roofing company that serves Orange County and runs Google Ads for "roof repair". After two weeks, the search terms report shows these clicks:
- "roof repair jobs near me" (job seekers)
- "how to fix a leaking roof yourself" (do-it-yourself)
- "roof repair kit" (product shoppers)
- "roofing contractor license exam" (research)
- "roof repair Phoenix" (wrong city)
- "emergency roof repair Santa Ana" (a great lead)
The right response is not to block "roof repair" or "roof". Instead, the company adds negative phrase match terms such as "jobs", "diy", "kit", "license exam" and "Phoenix", checks that "emergency roof repair Santa Ana" is still allowed, and adds the other states and cities it does not serve to a shared list. A week later, it repeats the review and finds fewer irrelevant clicks, so the budget reaches more people who could actually hire the company.
The same process works for any local service. Look at what real searchers did, sort the useful from the wasteful, and block the wasteful ones as precisely as you can.
Next-Level Tips
Use multi-word negatives instead of single words
Say you run a bakery and offer a free recipe card with each order. If you add "free" as a negative keyword, you block people searching for "free recipe card bakery". Instead, block a more specific phrase such as "free bread recipes". Multi-word negatives remove specific bad searches without over-blocking.
Try n-gram analysis
An n-gram is a short sequence of words that appears in many search terms. Export your search terms report, then count how often each word or two-word phrase appears alongside clicks and conversions. If a word like "download" shows up in many searches that cost money and never convert, it is a strong candidate for a negative keyword. You can do this in a spreadsheet, a script, or a PPC tool.
Maintain shared lists
If you run several campaigns, a shared negative keyword list saves time. Create one master list of universal exclusions, such as jobs and DIY, then apply it to all relevant campaigns. Add campaign-specific negatives on top.
- Create the list in the Shared Library under Tools.
- Add your terms with the right match types.
- Apply the list to the relevant campaigns.
- Update it when you spot new waste.
Use this view to access different ad groups and campaigns.
Consider other platforms
Microsoft Advertising also supports negative keywords with match types. The rules are similar but not identical, so check the platform's help pages before you copy a list across. In Google Shopping and similar feed-based campaigns, negative keywords still work, and you can also exclude products you do not want to promote.
Mistakes to Avoid
- Over-blocking. Do not exclude words that could still bring qualified traffic. Start with obvious negatives and add more based on data.
- Set and forget. Search behavior changes. Audit regularly and remove negatives that block good searches.
- Ignoring plurals and misspellings. Negatives do not match close variants automatically. Add the variants that matter.
- Blocking your own keywords. Check that a new negative does not conflict with a positive keyword you want.
- Forgetting seasonal changes. If you run a promotion on something you usually exclude, such as free estimates, pause or remove that negative for the promotion.
- Ignoring landing pages. If irrelevant searches keep getting through, the problem may be your ad text or landing page, not just the negative list.
Negative Keywords and Your Wider Strategy
PPC and SEO work well together. Paid ads can bring leads quickly while your organic rankings grow, and the search terms report gives you real data on how customers search, which you can use for content and page planning.

Negative keyword thinking also starts with a good keyword analysis, and it belongs inside a broader market analysis of your customers and competitors.
FAQs
What is the difference between negative broad, phrase and exact match?
Negative broad blocks searches that contain all your negative words in any order. Negative phrase blocks searches that contain those words in that order. Negative exact blocks only the exact search with nothing added.
Do negative keywords block plurals and misspellings?
No. Google Ads does not apply close variants to negative keywords, so add plural forms and common misspellings yourself.
How many negative keywords should I have?
There is no ideal number. Start with a core list of obvious exclusions, then add based on your search terms report. Quality matters more than quantity.
How often should I review search terms?
Weekly for new campaigns, then every two weeks or monthly. Review them sooner if your spend or keywords change.
Can negative keywords hurt my campaign?
Yes, if you block terms that bring good leads. Use specific multi-word negatives, use exact match for isolated problems, and recheck your lists regularly.
Should local businesses use account-level or shared negative lists?
Both are useful for universal exclusions like jobs and DIY. Keep campaign-specific negatives at the campaign or ad group level.
Final Thoughts
Negative keywords will not fix a weak offer or a poor landing page, but they are a cheap, fast way to stop paying for clicks that were never going to turn into customers. Build a starting list before launch, review your search terms regularly, and keep your match types precise.
