Most contractors waste money on Google Ads in six predictable places: broad match keywords pulling in searches that were never jobs, geographic targeting that covers areas you will not drive to, conversion tracking that counts form fills while your customers call, ads running at hours nobody can answer the phone, traffic pointed at a homepage instead of the matching service page, and a negative keyword list that was built once and abandoned. Home service clicks are expensive because the jobs are valuable, which means each of these mistakes costs more here than in almost any other industry.
Where does the money actually go?
Start with the mechanism. You are paying per click, and the cost per click in the trades is high because everyone knows an HVAC replacement is worth a lot. That makes the economics unforgiving: a modest share of wasted clicks eats the margin on the jobs you do win.
Waste is not usually one dramatic failure. It is a steady leak from several places at once, none of which looks alarming on its own.
The pattern worth internalizing is that Google's defaults are not built for you. Broad match, automatic targeting expansion and the default conversion settings all favor volume, because volume is what the platform optimizes toward. A contractor working one county needs the opposite of volume — precision.
Is my keyword matching too broad?
This is the biggest single leak in most contractor accounts.
Broad match lets Google show your ad for searches it considers related. "Water heater repair" can pull in "how to repair a water heater yourself," "water heater repair parts," "water heater repair jobs" and "water heater repair course." Every one of those costs the same as a homeowner who needs a plumber today.
The DIY searches are the worst offenders because the intent is explicitly not to hire anyone. Someone searching how to fix it themselves will click, read, and leave.
How to check: open the search terms report in your account, not the keyword list. It shows what people actually typed. Sort by cost and read the top fifty. Most contractors find something in there that makes them wince within the first ten rows.
Am I paying for areas I will not serve?
Geographic targeting has two settings that quietly cost money.
The first is radius. A thirty-mile radius drawn around your shop looks generous on a map and includes towns you would decline a job in. Every click from those towns is money spent on work you will not take.
The second is subtler. Google's location options default to including people who show interest in your area, not just people in it. That means someone in another state researching contractors in your city can trigger your ad.
How to check: look at the location report for where clicks actually came from, and check whether your campaign is set to "presence" or "presence or interest." The second is the default and it is rarely what a contractor wants.
Is my conversion tracking measuring the wrong thing?
If you take most bookings by phone and your account only counts form fills, then the data steering your budget is describing a minority of your business.
This matters more than it sounds. Google optimizes toward whatever you tell it is a conversion. If form fills are the only signal, it learns to find people who fill in forms — a different and usually less valuable group than people who call.
How to check: look at what is listed under conversions in your account. If there is no call tracking, or calls are counted without being tied back to the keyword that produced them, the account is being optimized on partial data. Fixing this is usually the highest-value change available, because everything downstream depends on it.
Are my ads running when nobody can answer?
An ad that runs at 9pm produces a call at 9pm. If nobody answers, you paid for a lead and handed it to whoever called next.
This is the most straightforwardly wasteful pattern in contractor advertising, and it is common because ad scheduling is not on by default.
Two ways to fix it, and they are not mutually exclusive. Restrict the schedule to hours you can cover. Or keep running and put missed call text back or an AI voice agent behind the ads so after-hours calls get an immediate reply instead of a voicemail. The second usually earns more, because urgent after-hours calls are often the most valuable work you get.
What you should not do is run ads around the clock with voicemail as the safety net. That is paying full price for a lead and giving it away.
Where is my traffic landing?
Someone who searched "drain cleaning" and lands on a homepage listing eleven services has to work out where to go next. A meaningful share do not bother.
Matching the landing page to the search does two things: it converts better, and it lowers what you pay per click, because Google rewards relevance. It is one of the few changes that improves both sides of the equation at once.
How to check: look at the final URL on each ad group. If several point at your homepage or at a general services page, that is the fix. This is also why service pages that stand on their own matter for paid traffic and not just for organic ranking.
When was my negative keyword list last updated?
Negatives are where most of the recoverable savings sit, and they decay.
New waste appears constantly. Searches nobody predicted, job-seekers, students, parts buyers, people researching a DIY repair. A negative list built at launch and never revisited stops catching things within a couple of months.
The categories worth excluding in almost every trade: job and career searches, salary searches, DIY and how-to, parts and supplies, training and certification, free, cheap, and the names of competitors you do not want to bid against.
How to check: the search terms report again. This is a job for once a month, not once a year.
What should I fix first?
In this order, because each one makes the next more effective:
- Conversion tracking, including calls. Without it you are guessing at everything else.
- Response handling. Missed call text back or a live answer path before spend goes up. Paying for a click and missing the call is the most expensive mistake available.
- Search terms review and negatives. The fastest saving, available this week.
- Geography and location settings. Quick, and usually reveals something.
- Landing pages. Slower, compounding, improves cost per click as well as conversion.
A note on the second one: it is out of order if you think of this as an ads problem. It is in order if you think of it as a revenue problem, which is the right frame. There is no point improving the efficiency of a funnel that leaks at the bottom.
Frequently Asked Questions
How much should a contractor spend on Google Ads?
There is no useful universal figure — it depends on your trade, your market and what clicks cost there. Anyone quoting a number without looking at your service area is guessing. A more useful question is what a booked job is worth to you, because that sets the ceiling on what a click can sensibly cost.
Why are my clicks so expensive?
Because the jobs are valuable and competitors know it. Emergency trades searches are among the most expensive in any industry. The response is not to bid less, it is to waste less — precision in keywords, geography and landing pages does more than lowering bids.
Should I run ads or focus on SEO?
Both, with ads first for urgency. Ads produce calls immediately and stop the moment you stop paying. Local SEO takes months and keeps producing. Ads buy time while the organic side builds.
Is Google's automated bidding worth using?
It can be, but only once conversion tracking is accurate. Automated bidding optimizes toward the signal you give it, so feeding it form fills when your business runs on phone calls teaches it to find the wrong people faster.
How long before I can tell if an account is working?
You need enough clicks for the data to mean something, which for a small local account can take several weeks. Judging performance after a few days is reading noise. Judging it after three months without checking search terms is expensive.
Should I pause ads in my slow season?
Not necessarily — costs usually fall too, and staying visible in the quiet months is cheaper than rebuilding momentum. What matters more is matching spend to the capacity you actually have, in both directions.
