Short answer: Negative keywords are terms you add to a Google Ads campaign to stop your ads from showing on irrelevant searches. By excluding words like “free,” “jobs” or competitor names, you prevent wasted clicks, protect your budget, and lift click-through rate, Quality Score and return on ad spend.
What are negative keywords?
In Google Ads, regular keywords tell Google which searches should trigger your ad. Negative keywords do the opposite — they tell Google which searches should not trigger it. If you sell premium software and add “free” as a negative keyword, your ad will not appear when someone searches “free software,” because those users are unlikely to buy.
Every irrelevant click costs money and dilutes your metrics. Negative keywords are the primary tool for filtering out that waste, making them essential to any profitable campaign.
Why negative keywords matter
- Stop wasted spend: You stop paying for clicks that will never convert.
- Higher relevance: Ads show only to genuinely interested searchers.
- Better CTR and Quality Score: Fewer irrelevant impressions raise click-through rate, which improves Quality Score and can lower your cost per click.
- Improved ROAS: Budget concentrates on searches that drive revenue.
- Cleaner data: Reports reflect real intent, so optimisation decisions improve.
Because negatives directly protect budget, they are one of the most effective ways to reduce CPC and improve efficiency — a natural companion to understanding what CPC is.
Negative keyword match types
Just like normal keywords, negatives use match types — but they behave slightly differently, and importantly, negative match types do not consider close variants, synonyms or misspellings.
| Match type | Format | Blocks when |
|---|---|---|
| Negative broad | free trial | The search contains all these words in any order (not close variants) |
| Negative phrase | "free trial" | The search contains this exact phrase in order |
| Negative exact | [free trial] | The search is exactly this term with no extra words |
Key nuance: With negative broad match, an ad is only blocked if the search includes every word in your negative. So “free trial” broad would not block “free software” because “trial” is missing. Use single-word negatives when you want to block a term wherever it appears.
How to find negative keywords
- Search terms report: The single best source — it shows the real queries that triggered your ads. Add irrelevant ones as negatives.
- Keyword research tools: Spot related but unwanted terms before launch.
- Common irrelevant modifiers: free, cheap, jobs, salary, DIY, PDF, tutorial, second-hand, review, meaning.
- Competitor and brand terms: Decide whether to bid on or exclude them.
- Intent mismatches: Informational queries when you want buyers.
Negative keyword lists and levels
You can apply negatives at three levels:
- Ad group level: Fine control; also used to stop keywords cannibalising each other between ad groups.
- Campaign level: Blocks a term across the whole campaign.
- Negative keyword lists (shared): Build one master list (e.g. of “free/jobs/DIY” terms) and apply it to many campaigns at once.
Shared lists are a huge time-saver for accounts with many campaigns. Maintain a universal exclusion list and reuse it everywhere.
A practical example
Suppose an academy advertises paid cyber security courses. The search terms report shows clicks from “free cyber security course,” “cyber security jobs” and “cyber security course PDF.” None of these searchers want to pay for training, so adding free, jobs and PDF as negatives immediately stops the waste and redirects budget to buyers. Over a month, that can meaningfully lower cost per enrolment.
Best practices for 2026
- Review the search terms report weekly — new irrelevant queries appear constantly.
- Build shared negative lists for account-wide junk terms.
- Do not over-block. Aggressive negatives can suppress valuable traffic; check impressions before adding.
- Use negatives to separate ad groups so the right ad shows for each theme.
- Add competitor terms carefully — sometimes you want them, sometimes not.
- Remember match-type behaviour — negatives ignore close variants, so add plurals and misspellings deliberately.

FAQ
What is a negative keyword in Google Ads?
A negative keyword is a term you add to prevent your ads from showing on searches that include it, so you avoid irrelevant clicks and wasted budget.
Do negative keywords save money?
Yes. By blocking irrelevant searches, they cut wasted spend, raise click-through rate and Quality Score, and can lower your effective cost per click.
What is the difference between negative broad, phrase and exact?
Negative broad blocks searches containing all the words in any order; negative phrase blocks the exact phrase in order; negative exact blocks only the precise term with no extra words.
Do negative keywords block close variants?
No. Unlike positive keywords, negatives do not automatically block plurals, misspellings or synonyms, so you must add those variations yourself.
