In the competitive world of Google Ads, every click matters. While many advertisers focus on selecting the right keywords to attract potential customers, they often overlook the power of negative keywords—a critical tool for optimizing ad performance. By strategically filtering out irrelevant searches, negative keywords ensure your ads are shown only to the most qualified audience, reducing wasted spend and improving overall campaign efficiency.
Why Negative Keywords Are Essential?
Imagine you own an online store selling premium leather shoes. You invest in Google Ads, expecting high-quality leads, but soon realize that a significant portion of your budget is being spent on users searching for terms like “cheap leather shoes”, “free shoe giveaways”, or “how to clean old sneakers.” These clicks are unlikely to convert, yet they still consume your advertising budget.
This is where negative keywords come into play. By excluding irrelevant or low-intent search terms, you can:
✅ Reduce wasted ad spend by preventing unqualified traffic.
✅ Improve ad relevance, leading to a higher Quality Score and lower cost-per-click (CPC).
✅ Boost conversion rates by ensuring your ads are shown only to users with strong purchasing intent.

What Are Negative Keywords?
In Google Ads, keywords determine when and where your ads appear. However, not all searches are relevant to your business. Negative keywords allow advertisers to exclude specific search terms from triggering their ads, preventing wasted clicks and ensuring a more refined audience reach.
How Negative Keywords Work?
When a user searches on Google, the platform matches their query with the keywords in your campaign. If a search term includes a negative keyword you’ve specified, your ad won’t appear for that search, even if other keywords in your campaign match the query.
For example:
✅ If you sell luxury handbags and add “cheap” as a negative keyword, your ad won’t show for searches like “cheap designer handbags” or “affordable luxury bags.”
✅ If you run a premium fitness coaching service, adding “free” as a negative keyword ensures you don’t pay for clicks from users looking for “free personal training sessions.”
By carefully selecting negative keywords, you can prevent irrelevant traffic, improve your ad quality, and maximize your budget efficiency.
Negative Keywords vs. Regular Keywords
While regular keywords help your ads appear for relevant searches, negative keywords do the opposite—they block unwanted traffic. The key difference lies in intent: regular keywords tell Google when to show your ads, while negative keywords tell Google when not to show them.
Many advertisers focus solely on selecting the right keywords but fail to recognize the importance of filtering out unqualified traffic. This oversight can lead to wasted ad spend and lower overall campaign performance.
Why Negative Keywords Are a Game-Changer?
Using negative keywords effectively can:
🔹 Improve campaign relevance by ensuring ads reach the right audience.
🔹 Lower cost-per-click (CPC) by eliminating unqualified traffic.
🔹 Increase conversion rates by focusing on high-intent users.
🔹 Enhance Quality Score, leading to better ad placements.
With a clear understanding of what negative keywords are and how they function, the next step is to explore the different match types and how they affect your ad visibility.
Benefits of Using Negative Keywords in Google Ads
Negative keywords are a powerful tool that can dramatically improve the efficiency of your ad campaigns. By filtering out unwanted traffic, they help businesses maximize their advertising budget and drive higher-quality leads.
Key Benefits of Negative Keywords
✅ Reduce Wasted Ad Spend – Eliminating irrelevant searches prevents you from paying for clicks that are unlikely to convert.
✅ Improve Ad Relevance – Ensuring your ads only appear for the right audience increases engagement and leads to a better Quality Score.
✅ Lower Cost-Per-Click (CPC) – A higher Quality Score often results in reduced CPC, allowing you to get more value from your budget.
✅ Increase Click-Through Rate (CTR) – By showing your ads only to users with high purchase intent, you attract more qualified traffic, which improves your CTR.
✅ Boost Conversion Rates – When your ads are displayed only to the most relevant users, your chances of turning clicks into sales significantly increase.
By integrating negative keywords into your strategy, you ensure that your advertising spend is allocated to the right audience, making every dollar count.
Types of Negative Keyword Match Types
Negative keywords come in three different match types, each affecting how search terms are blocked. Understanding these distinctions is essential for precise targeting.
1. Broad Match Negative
Prevents your ad from appearing if the search contains all the negative keyword terms, in any order. However, if additional words are included, the ad might still appear.
🔹 Example: If you add “cheap shoes” as a broad match negative keyword, your ad won’t show for “where to buy cheap shoes”, but it might still appear for “cheap running shoes online”.
2. Phrase Match Negative
Blocks your ad if the exact phrase appears in the search, in the same order, even if other words are included before or after.
🔹 Example: If “cheap shoes” is a phrase match negative, your ad won’t appear for “best cheap shoes online”, but it could still show for “discounted shoes”.
3. Exact Match Negative
Prevents your ad from showing only if the search exactly matches your negative keyword.
🔹 Example: If [cheap shoes] is an exact match negative, your ad won’t appear for “cheap shoes”, but it will show for “best cheap shoes” or “cheap running shoes”.
Each match type serves a different purpose, and using a combination of them allows for a more refined and cost-effective campaign.
How to Find Negative Keywords for Your Campaigns?
Identifying the right negative keywords requires data analysis and strategic thinking. Here are some effective methods to discover which keywords should be excluded.
1. Analyze the Search Terms Report
Google Ads provides a Search Terms Report, which shows the actual queries triggering your ads. Regularly reviewing this report helps identify irrelevant or low-intent searches to add as negative keywords.
2. Use Keyword Research Tools
🔹 Google Keyword Planner – Provides insights into search volume and potential variations of keywords.
🔹 SEMrush / Ahrefs – Help identify unwanted keyword trends and common irrelevant searches in your industry.
🔹 Google Autocomplete & Related Searches – Typing your main keywords in Google can reveal variations that should be excluded.
3. Analyze Competitor Ads
Studying competitor search ads can give you insights into keywords that might not be relevant for your business. If a competitor is ranking for broad terms, their search results might contain unwanted phrases you should exclude.
4. Identify Common Mismatches
Think about words that often cause irrelevant clicks in your industry. Some typical negative keywords include:
❌ “Free” (if you only offer paid services)
❌ “Jobs” / “Careers” (if you are not hiring)
❌ “Cheap” / “Discount” (if you sell premium products)
A proactive approach to finding and implementing negative keywords ensures that your ads reach only the right audience and avoid unnecessary spending.
How to Add Negative Keywords in Google Ads (Step-by-Step)?
Once you’ve identified your negative keywords, it’s essential to add them correctly within your Google Ads account.
Step 1: Access the Negative Keywords Section
- Log into Google Ads.
- Click on the Campaigns or Ad Groups tab (depending on where you want to apply the negative keywords).
- Select Keywords → Negative Keywords.
Step 2: Add Negative Keywords Manually
- Click the + button to add new negative keywords.
- Enter your list of negative keywords (one per line).
- Select whether to apply them to a campaign level or ad group level.
Step 3: Create a Negative Keyword List (Recommended for Organization)
- In the same Negative Keywords section, click Tools & Settings → Shared Library → Negative Keyword Lists.
- Click Create a new list, name it appropriately, and enter your negative keywords.
- Apply the list to relevant campaigns to ensure consistent filtering across multiple ad groups.
Step 4: Regularly Update and Optimize
Negative keywords should not be a set-it-and-forget-it approach. Regularly reviewing and updating your list ensures continuous improvement in ad performance.
Common Mistakes When Using Negative Keywords (and How to Avoid Them)
Even experienced advertisers make mistakes when implementing negative keywords. Here are some common pitfalls and how to prevent them.
1. Being Too Aggressive with Negative Keywords
🚨 Problem: Overusing negative keywords can accidentally block valuable search traffic.
✅ Solution: Use phrase or exact match negatives instead of broad match when blocking specific queries.
2. Forgetting to Update Negative Keywords
🚨 Problem: Markets change, and keywords that were once irrelevant may become valuable.
✅ Solution: Review your search terms report weekly to adjust your negative keyword list accordingly.
3. Not Differentiating Between Campaign and Ad Group Levels
🚨 Problem: Applying negative keywords at the campaign level may block relevant searches for some ad groups.
✅ Solution: Use ad-group-level negatives to refine specific ads instead of blocking them across an entire campaign.
4. Ignoring Synonyms and Variations
🚨 Problem: A single negative keyword might not cover all unwanted variations.
✅ Solution: Use Google’s Keyword Planner to identify related terms to exclude.
5. Not Using Negative Keywords for Display and Shopping Campaigns
🚨 Problem: Many advertisers only use negative keywords for search ads, ignoring their impact on Display and Shopping campaigns.
✅ Solution: Apply negative keywords across all campaign types to improve targeting consistency.
By avoiding these mistakes, you ensure that negative keywords enhance your campaign’s effectiveness rather than limit its potential.
Advanced Strategies for Maximizing Performance with Negative Keywords
Once you’ve mastered the basics, advanced strategies can further refine your campaigns, improving efficiency and increasing ROI.
1. Segment Negative Keywords by Campaign Type
Different campaign types require tailored negative keywords:
✔ Search Ads: Exclude low-intent searches.
✔ Display Ads: Prevent ads from appearing on irrelevant websites.
✔ Shopping Ads: Block searches for products you don’t sell.
2. Prevent Keyword Cannibalization
Avoid competing against yourself by separating branded and non-branded campaigns.
🔹 Example: If you run Nike Running Shoes and General Running Shoes campaigns, add “Nike” as a negative keyword in the general campaign.
3. Use Negative Keyword Lists for Efficiency
Save time by organizing negative keywords into lists:
✔ Competitor Names – If you don’t want to bid on competitor searches.
✔ Low-Intent Terms – Words like free, cheap, DIY, tutorial.
✔ Job & Career Searches – To exclude jobs, hiring, career.
4. Monitor and Optimize Regularly
Negative keywords require continuous monitoring. Review the Search Terms Report, update exclusions based on new trends, and ensure your campaign remains optimized.
