Every tradie who has run Google Ads has felt it. You set a daily budget, the clicks roll in, and at the end of the week you have spent a few hundred bucks and booked next to nothing. The problem usually is not your ad or your price. It is who is clicking. Negative keywords are the lever that stops the wrong people from ever seeing your ad, so your budget goes to folks who actually want to hire you.
What negative keywords actually are
When you run a search campaign, you tell Google which words should trigger your ad, like 'emergency plumber Brisbane'. But Google is generous. It also shows your ad for loads of loosely related searches you never picked. That is where the waste creeps in.
A negative keyword is the opposite of a normal keyword. Instead of saying 'show my ad when someone types this', you are saying 'never show my ad when someone types this'. Add 'jobs' as a negative and your plumbing ad stops appearing when someone searches 'plumber jobs Brisbane'. Simple as that.
Why they save you real money
You pay every time someone clicks, whether they are a homeowner with a burst pipe or a school kid doing a careers assignment. Both clicks cost the same. Negative keywords quietly filter out the tyre-kickers, the job-seekers and the DIY crowd before they ever cost you a cent.
Here are the usual culprits worth blocking for most trades:
- jobs, careers, hiring, apprenticeship, salary, wage, TAFE - people looking for work, not a tradie
- DIY, how to, how do I, tutorial, YouTube - people wanting to do it themselves
- free, cheap, cheapest, bargain, discount - price-shoppers who will not pay your rate
- course, courses, training, certificate, licence, ticket - people studying, not hiring
- second hand, used, wholesale, supplies, parts - people buying gear, not a service
- meaning, definition, what is, wiki - pure research, zero buying intent
Block those and you often trim a big slice off your spend without losing a single genuine enquiry.
How to find where your money is leaking
You do not have to guess. Google shows you the exact phrases people typed before they clicked your ad. This is the single most useful report in the whole platform, and most tradies never open it.
Find your search terms report
- In Google Ads, go to your campaign or ad group
- Open the 'Search terms' report (under Insights or Keywords, depending on your view)
- Sort by cost, highest first, so the biggest wasters float to the top
- Read down the list and flag anything with no chance of becoming a job
You will spot patterns fast. Maybe you are a sparky and half your clicks are people searching 'electrician jobs near me' or 'how to wire a powerpoint'. Each one is money gone. Tick the box next to those terms and add them as negatives right there in the report.
A starter negative keyword list
If you want a head start, drop these into a shared negative keyword list and apply it across all your campaigns. Adjust to suit your trade.
- jobs, job, careers, career, hiring, vacancy, recruitment
- apprentice, apprenticeship, trainee, work experience
- salary, wage, pay rate, award rate
- TAFE, course, courses, training, certificate, cert, diploma
- DIY, how to, how do i, tutorial, guide, steps
- free, cheap, cheapest, bargain, discount, budget
- second hand, used, wholesale, supplies, tools, parts
- meaning, definition, wiki, wikipedia, reddit
Keep it as a living list. Every few weeks, open the search terms report again and add whatever new junk has crept in.
Tighter targeting means every click could be a job
The real win is not just saving money, it is what you do with the money you keep. When your budget only chases people with genuine intent, more of your clicks turn into calls, and more of those calls turn into booked work.
That said, even a red-hot lead is worthless if you cannot pick up. You are up a ladder or under a sink, the phone rings, and it goes to voicemail. Most people just ring the next tradie. This is where InstantLead earns its keep: it texts back every missed call in under five seconds, works out the caller's name, job and how urgent it is, then pings you so you can jump on it the moment you are free. Pair tight Google Ads targeting with fast follow-up and you stop paying for clicks that slip away.
A few habits that keep spend clean
- Check the search terms report fortnightly - ten minutes now saves real dollars later
- Add negatives at the account or campaign level with shared lists so a new campaign inherits them automatically
- Do not go overboard - blocking too aggressively can hide you from good searches, so review before you bulk-add
- Watch for your own trade's oddities - a 'gas fitter' might want to block 'gas station' and 'gas prices'
