Negative Keywords in Google Ads: A Simple Guide
Negative keywords help prevent your Search ads from appearing for searches that are unlikely to be useful to your business.
Negative keywords help prevent your Search ads from appearing for searches that are unlikely to be useful to your business.
Negative keyword example
A company that only installs new kitchens might review whether searches containing “DIY”, “jobs”, “training” or “used” match its offer. Do not exclude terms blindly: check actual search intent and the match-type implications before making changes.
Practical next step: Note your business-specific assumptions and discuss them before setting an advertising budget.
This guide is for UK business owners considering or improving paid search. The examples explain practical decisions rather than predicting results for a particular account.
What negative keywords do
They exclude selected search terms from eligible ad traffic. They can help reduce wasted spending on irrelevant searches.
How to find candidates
Look at the search terms report and compare real searches with services you do and do not provide. Common examples could include jobs, courses, free or unrelated products—but never assume a term is always irrelevant.
Match types matter
Negative broad, phrase and exact match behave differently from positive keywords. Test carefully to avoid blocking worthwhile customer searches.
Build lists carefully
Keep obvious account-wide exclusions separate from service-specific exclusions. Review conflicts between campaigns.
Review regularly
Customer behaviour and search wording change. Negative keywords are an ongoing quality tool, not a one-off setup task.
Example: protecting a service campaign from irrelevant intent
A company selling paid commercial services may want to review searches containing words such as “free”, “jobs”, “salary” or “DIY”, but not blindly block them: a relevant service can contain an otherwise unexpected term. Review actual search queries and account goals before adding negatives, and check match types and campaign scope.
Practical next steps
- Write down one commercial goal and what a qualified enquiry means.
- Check the search terms, business economics and tracking information relevant to this topic.
- Record a baseline and review enough genuine data before changing the budget.
- Keep your Google Ads account accessible and management fees clearly documented.
Common questions
Do negative keywords improve campaign performance?
Review the search terms report to identify queries that are clearly irrelevant to the services or locations you sell. Avoid excluding words that also appear in valuable queries.
Can too many negative keywords reduce leads?
Negative match types work differently from positive keywords. Test the exact exclusions and their potential impact before adding broad lists across an account.
Before you make a decision
Use this short decision check alongside your own account and commercial information:
- Confirm the action you want a customer to take and how you will measure it.
- Check the assumptions behind any worked example against real business costs.
- Separate Google advertising spend from management charges and other costs.
- Review customer outcomes and lead quality, not simply clicks or impressions.
