What Are Negative Keywords in PPC?

Negative keywords prevent your ads from showing for irrelevant searches, saving money and improving targeting. For example, a bakery selling cakes might add “free recipes” as a negative keyword to avoid clicks from people looking for DIY instructions rather than purchasing cakes.

Strategic use of negative keywords can reduce wasted spending by 15-30% while improving conversion rates.

How Negative Keywords Work

When you add a negative keyword to your campaign, Google won’t show your ads when someone’s search includes that term.

If you sell premium furniture and add “cheap” as a negative keyword, your ads won’t appear for searches like “cheap furniture” or “cheap dining tables.” This filters out bargain hunters unlikely to buy your high-end products.

Negative keywords work across match types just like regular keywords, with broad, phrase, and exact match options.

Why Negative Keywords Matter

Without negative keywords, you’ll pay for many irrelevant clicks that never convert.

Blocking unqualified traffic reduces costs per conversion. You spend the same amount on ads but get more qualified clicks.

Better targeting improves CTR and Quality Score. When your ads only show to relevant searches, more people click, which signals to Google that your ads are high quality.

Types of Negative Keywords to Add

Several categories of negative keywords apply to most businesses.

Job-Related Terms

Add “jobs,” “careers,” “salary,” and “hiring” unless you’re recruiting. These searches want employment, not your products or services.

Free or Cheap Searchers

Block “free,” “cheap,” “discount,” and “coupon” if you sell premium products. These searchers rarely convert for higher-priced offerings.

DIY Terms

Add “DIY,” “how to,” “tutorial,” and “instructions” if you provide services. People searching for DIY guides want to do it themselves, not hire you.

Unrelated Products

Block terms for products you don’t sell. A Toyota dealer should add “Ford,” “Chevy,” and other competitors as negatives.

Information Seekers

Consider blocking “what is,” “how does,” and similar research terms if they don’t convert for your business.

Finding Negative Keyword Opportunities

Mine your search query reports for irrelevant terms costing you money.

In Google Ads, review the search terms report weekly. Look for queries that triggered your ads but have nothing to do with your business.

Sort by cost and impressions. Focus on expensive irrelevant terms wasting budget and high-volume terms diluting your CTR.

Check conversion rates by search term. Queries with zero conversions after 50 clicks probably belong in your negative keyword list.

Negative Keyword Match Types

Choose match types carefully to block the right searches without being too restrictive.

• Broad Match Negative: Blocks searches containing all negative keyword terms in any order.
• Phrase Match Negative: Blocks searches containing the exact phrase in that order.
• Exact Match Negative: Only blocks that exact query, nothing else.

Use broad match negatives carefully. Blocking “free” as broad match might block “free shipping,” which could be relevant.

Organizing Negative Keywords

Create negative keyword lists for different campaign types or industries.

Build a master list of universal negatives like “jobs” and “free” that apply to all campaigns. Create specific lists for particular services or products.

Share lists across campaigns to save time. Update one list and it applies everywhere automatically.

Common Mistakes with Negative Keywords

Avoid these errors that can hurt performance.

• Too Aggressive: Blocking too many terms limits reach and misses potential customers.
• Not Reviewing Regularly: New irrelevant searches appear constantly as campaigns run.
• Wrong Match Types: Using exact match when you need broad, or vice versa.
• Blocking Relevant Terms: Accidentally excluding keywords that actually convert.

Testing Negative Keywords

Before adding negatives broadly, test their impact.

Add questionable terms to one campaign first. Monitor how it affects impressions, clicks, and conversions for a week.

If performance improves or stays the same with lower cost, roll out to other campaigns. If performance drops, remove the negative.
