How to Use Negative Keywords to Improve PPC Performance

  • Post last modified:April 28, 2025

Running a pay-per-click (PPC) campaign is exciting. But, if you’re not careful, your ads could show up for the wrong people. That’s where negative keywords PPC strategies come in. In this guide, we’ll explore how to use negative keywords to improve your PPC performance without getting too technical. Let’s dive in!


Understanding the Basics of Negative Keywords

What Are Negative Keywords?

Negative keywords are words or phrases you tell your ads to avoid. They prevent your ads from showing up when people search for things that don’t match what you’re selling. Think of it like a filter for your ads.

For example, if you sell luxury watches, you might want to block searches like “cheap watches” or “free watches.”

Why Are They Important in PPC Campaigns?

Without negative keywords, your ads can appear for unrelated searches. That means you’re wasting money on clicks that don’t lead to sales. Negative keywords help you tighten your audience and only pay for clicks that matter.


How Negative Keywords Work in PPC Advertising

Blocking Irrelevant Traffic

Negative keywords tell platforms like Google Ads, “Don’t show my ad if someone types this word.” It’s a smart way to cut out traffic that’s unlikely to convert.

Saving Money on Ad Spend

Every click costs you money. Why pay for clicks from people who aren’t even looking for what you offer? Negative keywords keep your budget focused on real opportunities.


Types of Negative Keywords

Broad Match Negative Keywords

Broad match negative keywords block any search that contains all the words, in any order. It’s flexible but can sometimes block too much traffic if you’re not careful.

Phrase Match Negative Keywords

Phrase match blocks searches that include the exact phrase you specify, in the same order. This gives you more control than broad match.

Exact Match Negative Keywords

Exact match only blocks searches that are exactly the word or phrase you list. It’s the most precise way to control your ad triggers.


Finding the Right Negative Keywords

Using Search Query Reports

After your ads run for a bit, check the search query reports. They show exactly what people typed to see your ad. Find any irrelevant terms and add them as negatives.

Keyword Research Tools

Tools like Google’s Keyword Planner or SEMrush can also help spot words you don’t want to target.

Brainstorming Common Irrelevant Terms

Put yourself in your customers’ shoes. Think about what they might type when they aren’t a good fit for your offer.


How to Add Negative Keywords to Your Campaigns

At the Campaign Level

Adding negative keywords at the campaign level ensures that none of the ads in that campaign will show for unwanted searches.

At the Ad Group Level

If you have different products or services in the same campaign, you can add negatives to specific ad groups. This keeps things neat and targeted.


Best Practices for Managing Negative Keywords

Regularly Review Search Terms

Check your search terms every week or two. Trends change, and new irrelevant terms can pop up.

Update Negative Keywords Lists

Don’t just set it and forget it. Keep building and improving your negative keyword lists.

Organize by Themes

Group your negative keywords by common themes (like “cheap,” “DIY,” “free”) to stay organized.


Common Mistakes When Using Negative Keywords

Overblocking Valuable Traffic

Be careful not to block keywords that could actually bring you customers. Always double-check before adding a term.

Not Updating Lists Regularly

If you forget to update your negative keywords, your campaign performance might dip over time.


How Negative Keywords Help Improve PPC Metrics

Better Click-Through Rate (CTR)

When your ad shows only to the right people, your CTR goes up.

Higher Conversion Rate

Fewer wasted clicks mean more real buyers visiting your site.

Lower Cost Per Click (CPC)

Better targeting usually lowers your CPC because Google rewards relevant ads.


Examples of Negative Keywords in Action

Customizing Lists Over Time

As you gather data, refine your list to match real-world search behavior.


Advanced Strategies for Negative Keywords

Using Negative Keyword Lists Across Multiple Campaigns
