Google Ads for a one-truck shop: you're not buying jobs — you're buying clicks
Google Ads is not a do-it-yourself job when you're the one on the truck — and for some shops it isn't worth doing at all. This page hands you the honest math to tell which shop you are, and if the numbers say yes, exactly how to hire it out and inspect whoever runs it, the way you'd inspect a sub.
The search ads you'll be sold charge you every time a stranger clicks. Not when they call. Not when they book. Just the click. So the real question was never "what does a click cost." It's "what does one booked job cost me, once I count all the clicks that never called."
What you are actually paying for
Search ads on cost-per-click bidding charge you each time someone clicks your ad, whether they call you or close the tab a second later. You are not charged for the ad just showing up on the screen.
You set a cap called your maximum cost-per-click — the most you're telling Google you'll pay for one click. Google's page says a click won't cost more than the cap you set, and on the same page says the cap is the most you'll typically be charged, naming a setting — bid adjustments — that bills above it. Both sentences are Google's, as of July 2026. So don't budget off the cap. Once a month, open the account and read the average cost-per-click Google actually charged you. That number is your real click price.
So a click is not a customer. A click is a stranger who tapped your ad. Some of them call. Fewer of them book. And you paid for every last one, callers and closers and tire-kickers alike.
Picture your truck stopped at a red light with the trade painted on the door. Now picture paying a few bucks every time somebody leans in the window. The guy asking if you know a good electrician. The tire-kicker who "just had a quick question." They wave and drive off. That's a click. Google's meter runs on the lean-in, not the job.
The one number that matters: cost per booked job
Because you pay per click, your true cost hides one level down. A booked job costs you the click price, times how many clicks it takes to get a phone call, times how many calls it takes to land one job.
Let's run it with round made-up numbers, just to see the shape. These are not real rates — yours come from your own account, and they'll be different. Say a click costs $10. Say it takes 10 clicks to get one phone call. Say you book 1 of every 3 calls.
Ten dollars, times ten clicks, times three calls. That's $300 in ad spend for one booked job. If your job nets you less than that $300, you're upside down — you paid more to win the work than the work earned. If it's a full install worth many times that, you're way ahead.
Where these numbers come from, straight. Your close rate you already know, or you can count it off a month of your own call log. The average click price sits in a Google Ads account. Clicks-per-call is only there if call or conversion tracking was switched on — if it wasn't, count calls off your own log against the clicks the account reports. Never run ads? You don't have an account. So borrow a click price and run it anyway. If a $10 click needs a $300 job to break even and your ticket averages $180, you have your answer before you spend a dollar. If the account exists but a vendor holds the login, that's item 1 below, not a math problem.
Say this
A click costs me about your click price. It takes about how many clicks clicks to get one call. I book about 1 of every how many calls calls. So one booked job off Google Ads costs me about multiply them — and my average job nets me your profit per job.
If the cost-per-booked-job line is smaller than the profit line, ads can pay. If it's bigger, they don't — not at your job size, not yet.
Why this is a hire-out, not a Saturday project
The problem isn't really the click price. The problem is that you are the guy on the truck.
Somebody has to watch which words people are typing, cut the ones that waste money, and adjust the bids. That's not work you do from inside a crawlspace with your phone in your other hand.
So this is a hire-out. You don't stop being the boss; you sub the part you can't stand over all day, and then you inspect it.
Two honest exits before you hire anybody. If your phone already rings and you're booked weeks out, you may not need ads at all — that's the phone-problem chapter's whole point. And the honest "not yet" and "not you" both live in when ads make sense.
One door before you hire, if you're brand new. Google publishes 1-800-838-7971 for advertisers and a one-to-one call or chat scheduled "within the first 30 days of signing up." The same page sends active-campaign questions back to the Help Center. It's a door in, not a door through.
How to inspect whoever runs your ads
You already know how to inspect a sub's work. You do the same thing here. A straight ad-runner shows you all of this without being chased. A wolf hides it. Run the list:
- The account is in your name and on your card. You can log in and see everything. If a vendor sets it up on their own account, they can walk off with your ad history — and sometimes your leads — the day you part ways. Already the other way around? It isn't a lost cause. An existing account can grant Admin access to your own email address, and Admin sees billing, users, and every campaign. Ask for it in writing. If he stalls, you've learned what you needed to know: stop the card, and be ready to start a fresh account. Losing the ad history costs you some learning. Leaving him the keys costs you the leads too.
- The search-terms report, every month. This is the list of the actual words people typed that you paid for. It's where you see the clicks that were never your customer — "plumber salary," "fix a leak myself." A straight runner shows you this and cuts the junk. A wolf never brings it up.
- Calls and booked jobs — not clicks and impressions. An impression just means your ad appeared on a screen. "Impressions are up" is not a number you can put in the bank. Ask for calls and jobs, in plain text.
- The fee versus the ad spend. Ask two numbers: what they charge you to run it, and what actually goes to Google for the clicks. If the fee is bigger than the ad money it steers, ask what you're actually buying. The one math that judges every machine runs that rule out with numbers.
- No guarantees. Treat a promise of the top spot, or of a set number of leads, as a reason to walk. The honest version is "here's what we'll spend, here's what we'll watch, here's what it can't promise."
That's not web knowledge. It's show me, then I'll believe you.
"Before I hand you a dollar: the ad account goes in my name, on my card, and I can log in. Every month, show me the search-terms report — the actual words I paid for — and tell me calls and booked jobs, not clicks. And give me two numbers straight: your fee, and what's actually going to Google for the ads."
A straight runner answers each one plainly. A wolf gives you a paragraph about "getting you found" and never names a number. But a smooth talker can answer all five and still be no good. Talk isn't the test — the second month is. So get the five answers, then hold him to them: the account in your name before the first dollar, and the search-terms report plus calls-and-jobs on your screen by day 30. If day 30 comes and the report doesn't, you're out one month instead of one season. What to do on day 31 is when to fire your vendor, then leaving clean.
Print this: the one-truck Google Ads inspection
You can't turn a click into a customer, and neither can anyone you hire — no matter what they promise. What you can do is stop paying for the clicks that were never going to call, and only hand your money to someone who'll prove, every month, which clicks were which. Run your own math first, then judge whoever runs it by month two, not by the meeting. The rest of the paid-lead map, judged the same way, lives at the lead-machines hub. Google's other paid product bills a different way — that's Local Services Ads.
