What are Negative Keywords and How to Use Them Effectively
Key Takeaways
- Negative keywords stop your ads from showing on irrelevant searches that never convert.
- They improve click quality, CTR, Quality Score, and overall return on ad spend.
- Search terms reports and real customer enquiries are the most reliable discovery sources.
- Malaysian SMEs benefit most when exclusions reflect mixed-language searches and location intent.
- Regular reviews prevent small inefficiencies from quietly draining advertising budgets.
Negative keywords stop your Google Ads from appearing on irrelevant searches, saving budget and improving performance by filtering out low-intent traffic.
What Are Negative Keywords?
Negative keywords tell Google Ads when not to show your ads.
They are keywords or phrases that block your ads from appearing when users include those terms in their searches. This ensures your ads only appear for queries aligned with your business goals.
Search engines match user queries with ad keywords. Without negatives, your ad may show for searches that you don’t want, like “free”, “cheap”, or unrelated product types, leading to clicks that waste budget without conversions. Negative keywords prevent these.
How Do Negative Keywords Work In Google Ads?
Negative keywords act as filters stopping ads from showing on irrelevant searches.
In Google Ads, they are applied at campaign or ad group level to block certain search queries.
When someone searches on Google, the system compares their query against your positive and negative keywords:
- If the query matches a negative keyword, the ad will not show.
- If the query matches positive keywords but contains a negative that applies, the negative will override and block the ad.
This prevents showing ads to users who are unlikely to buy. For example, a local salon in Penang may not want ads showing for “salon jobs” or “free haircut tips”.
Negative keywords are not about avoiding traffic. They are about attracting the right moment of intent.
Without negative keywords, you’re paying for clicks you never wanted and customers you never asked for.
What Are The Types Of Negative Keywords?
Negative keywords come in three match types, each controlling how strictly your ads are filtered from irrelevant Malaysian searches.
| Match Type | How It Works In Practice | Malaysian Example |
| Negative Broad Match | Blocks searches containing all words, in any order. | Negative: kedai murah → Blocks “kedai murah shah alam”, “murah kedai perabot kl” |
| Negative Phrase Match | Blocks searches containing the phrase in the same order. | Negative: “kerja kosong” → Blocks “kerja kosong admin pj”, but allows “servis admin syarikat” |
| Negative Exact Match | Blocks only the exact search term. | Negative: [free delivery] → Blocks only “free delivery”, not “delivery murah kl” |
Search behaviour in Malaysia is rarely single-language. Queries often blend English, Bahasa Malaysia, and location cues like “KL”, “PJ”, or “near me”.
Broad negatives remove large volumes of waste quickly but can over-filter if used carelessly. Phrase and exact negatives provide safer control in multilingual environments where buying and research intent overlap closely.
What Are Common Negative Keyword Examples For Malaysian SMEs?
These negative keyword categories reflect real search intent patterns seen across Malaysian Google Ads accounts.
| Negative Keyword Category | Example Keywords | When Malaysian SMEs Should Use Them |
| Job And Career Intent | kerja, jawatan kosong, internship, career, vacancy | When you sell services or products and are not actively hiring. Prevents wasting spend on job seekers browsing ads during lunch breaks or late-night searches. |
| Education And Learning Intent | kursus, kelas, training, belajar, syllabus | When you offer done-for-you services, not workshops or certifications. Common among users researching skills rather than purchasing solutions. |
| DIY And Informational Intent | cara buat, how to, tutorial, DIY, contoh | When customers must buy from you instead of doing it themselves. Often appears in searches made at home after dinner when users want instructions, not vendors. |
| Free Or Extreme Price Seekers | free, percuma, murah gila, cheap, lowest price | When your business is positioned as value-based or premium. Helps avoid leads who abandon enquiries once pricing is discussed. |
| Research And Comparison Intent | review, comparison, vs, terbaik, ranking | When campaigns are optimised for conversions, not awareness. These users are still evaluating options and rarely convert on first click. |
| Irrelevant Transaction Modifiers | sample, template, pdf, download | When your offer is a paid service or product and not a downloadable resource. Common with office-hour searches from desktop users. |
| Geography-Based Exclusions | overseas, international, specific states you do not serve | When your service area is limited. Useful for SMEs that only operate within Klang Valley or selected cities. |
| Unrelated Industry Meanings | terms with double meanings in Malay or English | When keywords overlap with unrelated industries. Prevents accidental clicks from users searching for something entirely different. |

Why Negative Keywords Matter For Malaysian Businesses
They save advertising budget while increasing campaign relevance and conversions.
Without negative keywords, Google Ads shows your ad broadly, including terms that are not relevant, resulting in:
- Wasted clicks that cost money but do not convert.
- Lower click-through rates (CTR) because ad is shown to uninterested users.
- Poor Quality Score, increasing Cost Per Click (CPC).
- Reduced conversion rates, hurting ROI.
- Misleading performance data
For example, a Kuala Lumpur café might inadvertently show ads when people search “café recipes”, drawing traffic that will never convert into customers.
Many SMEs only realise the cost of irrelevant clicks after reviewing accounts with an experienced Google Ads Agency that audits search intent and wasted spend patterns.
How To Find Negative Keywords
The most effective negative keywords come from observing real user behaviour, not assumptions.
1. Review The Search Terms Report Weekly
The Search Terms Report is the fastest way to identify wasted spend.
Focus on:
- Queries with clicks but no conversions
- Searches that clearly signal research or job intent
- Terms unrelated to your core offer
Common Malaysian patterns that often appear:
- “kerja”, “jawatan”, “internship”
- “kursus”, “kelas”, “belajar”
- “cara buat”, “DIY”, “contoh”
Search intent reveals itself through phrasing. A home renovation contractor in Puchong gains nothing from clicks on “cara buat kabinet sendiri”. Weekly reviews prevent these small leaks from compounding into serious budget loss.
2. Identify Intent Modifiers That Never Convert
Certain words consistently signal low or zero purchase intent.
Common modifiers to evaluate:
- free, percuma
- murah gila, bajet
- tutorial, guide, how to
- review, comparison (for service-based SMEs)
These words indicate a mindset rather than a demographic. Someone searching “free logo design” is not negotiating price. They are avoiding it. Blocking these searches improves conversion rate without shrinking real demand.
3. Use Google Autocomplete And “People Also Ask”
Autocomplete exposes how Malaysians naturally structure searches.
How to use it:
- Type your main keyword into Google
- Observe suggested completions
- Identify patterns unrelated to purchasing
Example for “accounting services”:
- “accounting services salary”
- “accounting services course”
- “accounting services example”
Autocomplete reflects collective behaviour at scale. It helps surface irrelevant intent before it starts consuming ad spend.
4. Analyse Behaviour Using Google Analytics
Negative keyword decisions improve when paired with on-site behaviour.
Look for:
- Very high bounce rates
- Short session duration
- No scroll or engagement events
When users leave immediately, it signals a mismatch between search intent and landing page promise. Negative keywords fix the issue upstream, before the click happens.
5. Listen To Sales Enquiries And WhatsApp Messages
Offline conversations often reveal online targeting gaps.
Repeated enquiries like:
- “I’m just researching”
- “Do you offer this for students?”
- “Are you hiring?”
These phrases belong in your negative keyword list.
Front-line interactions expose intent patterns that dashboards miss. SMEs that listen closely often optimise faster than larger competitors.
How Do You Add Negative Keywords In Google Ads?
Negative keywords are added directly inside Google Ads campaigns or ad groups.
Steps:
- Open Keywords and Search terms
- Review terms with spend but no conversions
- Select irrelevant queries
- Add as negative keyword and choose match type
This iterative process refines targeting continuously and prevents recurring waste.
Negative Keywords vs. Positive Keywords
Positive and negative keywords work together to shape intent.
| Feature | Positive Keywords | Negative Keywords |
| Purpose | Makes your ads show | Stops ads from showing |
| Goal | Capture relevant search | Prevent irrelevant traffic |
| Impact on CPC | Can raise through competition | Can lower by improving Quality Score |
| Role in Budget | Uses budget | Saves budget |
Positive keywords attract the audience. Negative keywords deny the audience who won’t buy from you. Both are essential to a healthy Google Ads strategy.
How To Use Negative Keywords Strategically
Negative keywords are not only about blocking waste. They shape demand quality.
1. Align Negative Keywords With Funnel Stage
Different campaign goals require different exclusion logic.
| Campaign Objective | Negative Keyword Approach |
| Brand awareness | Light filtering, avoid over-blocking |
| Lead generation | Exclude learning and job intent |
| Sales focused | Aggressive exclusion of low-intent terms |
A café in Bangsar running awareness ads should tolerate broader searches than a law firm in KL running lead generation. Over-filtering too early suppresses discovery.
2. Use Shared Negative Keyword Lists With Intention
Shared lists prevent repeated mistakes across campaigns.
Create shared lists for:
- Job-related searches
- Education and course intent
- DIY and tutorial intent
Apply them across all non-recruitment campaigns.
Shared lists create institutional memory inside the ad account. As campaigns scale, they protect consistency and reduce human error.
3. Localise Negative Keywords By Service Area
Not every location represents viable demand.
Examples:
- Exclude “Johor” if you only serve Klang Valley
- Exclude “Penang” for same-day delivery businesses in KL
- Exclude “overseas” if you only serve Malaysia
Geographic mismatches inflate CPC without improving conversions. Location-based negatives sharpen intent without reducing relevance.
4. Protect Premium Positioning With Price-Based Negatives
Price language filters perception.
Premium businesses often exclude:
- murah
- bajet
- cheap
- lowest price
Price shoppers convert poorly for premium offers. Excluding them aligns traffic with brand positioning and improves sales efficiency.
5. Prevent Campaign Cannibalisation
Negative keywords control internal competition.
Typical setup:
- Brand campaign excludes generic service terms
- Generic campaign excludes brand terms
This ensures the right campaign serves the right intent, stabilising CPC and improving attribution clarity.
6. Re-Evaluate Negative Keywords After Offer Changes
Promotions alter search behaviour.
If you introduce:
- Free consultations
- Trials
- Limited discounts
Previously excluded terms like “free” may require reassessment.
Negative keywords reflect strategy, not dogma. As offers change, exclusions must evolve.
Best Practices For Negative Keywords In Google Ads
Negative keywords work best when treated as a living system, not a one-time checklist.
Negative keywords should evolve with search behaviour, offers, and campaign maturity. The strongest Google Ads accounts treat them as operational hygiene, reviewed as often as budgets and bids.
How Often Should You Review Negative Keywords?
Weekly reviews for active campaigns prevent silent budget leaks.
Search behaviour shifts quickly in Malaysia due to:
- Seasonal promotions
- Festive periods
- Sudden trends driven by social media or news
A campaign that ran cleanly last month can start leaking budget this month. A weekly review catches low-intent queries before they quietly drain spend. For smaller SMEs with limited spend, bi-weekly reviews are acceptable, but monthly is already too slow.
Where Should You Add Negative Keywords?
Use the correct level to avoid over-blocking valuable traffic.
| Level | Best Use Case |
| Account Level | Universal exclusions like “jobs”, “internship”, “free” |
| Campaign Level | Intent-specific filtering based on campaign goals |
| Ad Group Level | Fine-tuning similar keywords with different intent |
Adding everything at account level feels efficient but often blocks future growth. A café running both catering and dine-in campaigns may need different exclusions. Structure preserves flexibility.
How Should You Choose The Right Match Type?
Start broad for obvious waste, then narrow for control.
Best practice approach:
- Broad match negatives for clear non-buying intent
- Phrase match for mixed-language or multi-word intent
- Exact match when blocking a very specific query
Malaysian searches often blend English, Bahasa Malaysia, and location cues. Phrase and exact match reduce accidental blocking when intent is ambiguous, such as “murah” combined with branded or premium queries.
How Do You Avoid Over-Filtering Your Campaigns?
Every negative keyword should answer one question: will this user ever convert?
Warning signs of over-filtering:
- Sudden drop in impressions without CPC improvement
- Loss of branded or high-intent long-tail searches
- Declining conversion volume despite stable CTR
A law firm excluding “cost” may remove price shoppers, but excluding “fees” entirely could block high-intent clients comparing options. Precision matters more than aggression.
Do’s And Don’ts For Using Negative Keywords
Do
- Review Search Terms Reports
- Use data, not assumptions.
- Use shared negative lists across campaigns.
- Balance between excluding irrelevant terms and not overblocking.
Don’t
- Add negative keywords once and forget them.
- Use overly broad negatives that block valuable searches.
- Ignore search trends or changes in behaviour.
- Optimise purely for lower CPC at the expense of conversions
Final Thought
Negative keywords are one of the highest-impact, lowest-cost optimisations in Google Ads.
Used correctly, they:
- Prevent wasted spend from non-buying searches
- Improve click quality, CTR, and Quality Score
- Protect campaign data from misleading signals
- Align ads with real purchase intent across mixed-language searches
For Malaysian SMEs, effectiveness depends on:
- Understanding how English and Bahasa Malaysia mix in daily searches
- Filtering job, learning, and DIY intent early
- Adjusting exclusions as offers, pricing, or service areas change
- Reviewing search terms consistently, not reactively
The most successful advertisers do not chase traffic volume. They refine intent until each click has a realistic chance of becoming a customer.
