Mastering Negative Keywords: Cutting Waste and Driving Efficiency
Negative keywords are an often underutilised but critical component of any high-performing PPC campaign. They act as a safeguard, ensuring your ads only appear for the most relevant searches—helping reduce wasted spend, improve click-through rates, and sharpen your targeting.
What Are Negative Keywords?
Negative keywords prevent your ads from appearing for specific search queries that are irrelevant to your offer. For example, if you offer premium financial consulting, you might add terms like “free” or “entry-level” as negatives to avoid clicks from users who aren’t your ideal customer.

Why They Matter
Implementing a solid negative keyword strategy can:
Reduce irrelevant traffic
Improve CTR and Quality Score
Lower CPC by avoiding uninterested users
Increase conversion rate by refining audience intent
How to Identify Negative Keywords
Search Terms Report: This tool reveals which queries triggered your ads. Regularly review it to weed out irrelevant terms.
Internal brainstorming: Think about what your service is not.
Competitor brand terms (when not bidding against them).
📌 Pro Tip: Be mindful of broad match types—they often bring in irrelevant traffic if not managed tightly with negatives.
Examples of Common Negative Keywords
Campaign Type | Suggested Negative Keywords |
|---|---|
B2B Lead Gen | Jobs, Careers, Internships |
High-End Services | Cheap, Free, DIY |
Local Services | Online-only, Out-of-area locations |
Niche Services | General/broad queries outside your scope |
Match Types for Negatives
Just like normal keywords, negative keywords use match types:
Broad: Blocks queries containing the negative term in any order
Phrase: Blocks queries containing the exact phrase
Exact: Blocks only the specific query entered

Ongoing Maintenance
A one-time setup isn’t enough. Ongoing optimisation of negative keywords ensures:
Continuous relevance as your campaign evolves
Better control as new search behaviours emerge
Less budget wastage over time
Set a recurring monthly reminder to review your Search Terms Report.
Why Work with a PPC Professional?
Choosing which keywords not to show for is as important as selecting the right ones. A PPC professional has the analytical lens and campaign experience to build and maintain a negative keyword strategy that saves money and sharpens targeting. It's this layer of precision that can make or break campaign profitability.
