How to Use Negative Keywords for Plumbing Google Ads
Negative keywords are an important part of managing Google Ads for a plumbing company.
They can help prevent your advertisements from appearing for searches that aren't relevant to the services you provide.
When used properly, negative keywords can help reduce wasted advertising spend and improve the quality of your traffic.
What Are Negative Keywords?
A negative keyword tells Google Ads that you don't want your advertisement to appear for certain types of searches.
For example, a plumbing company that provides professional services may not want to advertise for searches related to plumbing jobs or DIY instructions.
Potential negative keywords might include:
Jobs
Careers
Training
Classes
DIY
Tools
Supplies
The appropriate list depends on your business.
Why Negative Keywords Matter
Not every person searching for plumbing information is looking to hire a plumber.
Someone may be searching for:
How to fix a pipe
Plumbing tools
Plumbing jobs
Plumbing training
Plumbing supplies
Free plumbing advice
Those searches may not represent the customers you're trying to reach.
Negative keywords can help reduce exposure to these types of searches.
Start With Your Actual Search Data
Don't create your entire negative keyword strategy based on assumptions.
Review the searches that are actually triggering your advertisements.
Look for patterns involving:
Irrelevant services
DIY searches
Employment searches
Educational searches
Product searches
Unrelated locations
This can reveal opportunities to improve your campaigns.
Common Negative Keyword Categories
Jobs and Careers
If you're advertising plumbing services, you may not want to appear for searches such as:
Plumber jobs
Plumbing careers
Plumbing apprenticeships
Plumbing hiring
Training and Education
You may also want to exclude searches related to:
Plumbing classes
Plumbing courses
Plumbing certification
How to become a plumber
DIY Searches
Depending on your campaign strategy, you may want to review searches involving:
DIY plumbing
How to fix a leak
How to unclog a drain
How to replace a faucet
Some DIY searches can potentially become customers, so decisions should be based on actual performance.
Products and Supplies
A customer looking for a plumbing product may not be looking for a plumbing company.
Potential searches might include:
Plumbing supplies
Plumbing tools
Pipe fittings
Faucet parts
Toilet parts
Again, the right exclusions depend on the services and business model.
Don't Overuse Negative Keywords
Negative keywords can improve targeting, but they should be used carefully.
You don't want to exclude searches that could actually generate valuable customers.
For example, a search that looks informational at first may still result in someone hiring a professional.
Review actual lead quality before making major exclusions.
Review Search Terms Regularly
Negative keyword management isn't a one-time task.
As your campaigns generate more traffic, you'll discover new searches.
Some will be valuable.
Others will be irrelevant.
Regular review allows you to continually improve campaign targeting.
Connect Negative Keywords to Your Services
Your negative keyword strategy should reflect the services your company offers.
For example, a company that doesn't offer commercial plumbing may need to handle commercial searches differently from a company that actively serves commercial customers.
Don't automatically exclude an entire category without considering whether it could produce business.
Negative Keywords and Local Targeting
Location-related searches should also be reviewed.
A plumbing company may receive searches from areas outside its service area.
If those searches aren't valuable, they may identify opportunities for additional geographic controls.
Use Conversion Data
Search relevance is important, but actual business results are even more important.
Ask:
Did the search generate a call?
Was the lead qualified?
Was the customer within the service area?
Did the customer book a job?
Was the job profitable?
This information can help determine whether a search should be excluded.
Negative Keywords Are Part of Ongoing Management
Google Ads campaigns shouldn't simply be created and left alone.
Effective management can include:
Search-term reviews
Negative keyword updates
Keyword adjustments
Advertisement testing
Budget changes
Geographic optimization
Landing page improvements
