Google Ads either prints money or burns it, and the difference is arithmetic you can do in ten minutes. Here is the exact framework, plus the cases where you should not run ads at all.
Ask ten business owners about Google Ads and you get two camps. One says it is the best money they spend. The other says they tried it, burned two grand, and got nothing but tire kickers.
Both camps are telling the truth. Google Ads is not good or bad, it is a multiplier. It multiplies whatever math your business already has. So before anyone spends a dollar, do the math. It takes ten minutes and four numbers.
The four numbers
1. Average job value
What is a new customer worth on the first job? Be honest, not optimistic. A drain clearing might be $300. A heating system replacement might be $8,000. If your jobs range widely, use a realistic blend, not your best month.
Then ask the bigger question: what is that customer worth over time? A landscaper who lands a weekly mowing account in Marion is not winning one cut, he is winning a season, maybe five seasons, plus the fall cleanup and the mulch job. Recurring-revenue businesses can afford to pay far more for a lead than one-shot businesses, and most owners underprice this in their heads.
2. Close rate
Of the people who call or fill out your form, how many become paying customers? Most decent service businesses land somewhere between three-in-ten and six-in-ten on real inquiries. If you do not track this, start this week with a notebook by the phone. Guessing here breaks the whole calculation.
3. What a lead is worth to you
Multiply. If your average job brings in $600 of revenue and you close half of your leads, a lead is worth $300 of revenue to you. Now apply your margins and decide what you can actually pay. If roughly a third of revenue can go to acquiring work and still leave healthy profit, you can pay up to about $100 per lead and win. That number, your break-even cost per lead, is the whole ballgame. Write it down.
4. What a lead will cost
This is where the click market comes in. For local service keywords, clicks commonly run anywhere from a few dollars into the tens of dollars, and competitive emergency trades like plumbing and HVAC sit at the expensive end. Those are market ranges, not quotes, and your actual costs depend on your trade, your towns, and how well the account is run.
Cost per lead is cost per click divided by your site's conversion rate, the percentage of visitors who actually contact you. And that is the number nobody talks about, because it belongs to your website, not to Google.
A worked example
Take a hypothetical Wareham HVAC company. Say clicks in their market average $15. Send those clicks to a slow, generic homepage that converts 2 of every 100 visitors, and each lead costs $750. If their break-even is $150 per lead, that account is a bonfire, and no amount of keyword tweaking saves it.
Same company, same $15 clicks, but now the traffic lands on a fast page built for lead capture that converts 10 of every 100 visitors. Each lead costs $150. At break-even or better, with recurring maintenance customers stacking up behind the first jobs, the account prints money. Nothing about the ads changed. The website changed. A five-times difference in conversion rate is a five-times difference in cost per lead, and swings like that between weak and strong pages are exactly why the two camps of owners disagree so bitterly.
When Google Ads is a money pit
Ads reliably lose money in a few recognizable situations:
- The landing site is weak. Slow on phones, vague about services and service area, buried phone number, untested form. You are paying real dollars per click to introduce people to a site that quietly sends them away.
- Nothing is tracked. If you cannot say which calls and form fills came from ads, you cannot calculate cost per lead, which means you are not running a campaign, you are making a donation.
- Nobody answers the phone. A missed call from an ad click is among the most expensive missed calls in your business. If you cannot answer or return calls fast, fix that before buying more of them.
- The math never worked. Low job values plus expensive clicks plus no repeat business can make break-even impossible. Better to learn that on paper for free than in the account for thousands.
When ads print money
Flip those conditions and the picture changes completely. Ads tend to work beautifully when job values are high or customers are recurring, when the destination page is fast and built to convert, when every lead is tracked back to its source, and when someone competent is managing the account: pruning wasted spend, tightening the service area to the towns you actually want, and writing ads that match what people search. For a South Coast trades business that checks those boxes, ads are often the fastest lever available, because they put you in front of someone at the exact moment their furnace died.
The honest caveat: some of you should not run ads yet
We manage Google Ads for local service businesses, so believe us when we say this against our own interest. If your website is weak, do not hire us for ads. Fix the site first. Sending paid traffic to a page that does not convert is renting a billboard for a store with a locked door. And if you are booked out months with no capacity, ads would just buy you leads to disappoint. Improving your site helps you at every future moment. Ads only help while the meter is running, and only when the rest of the machine works.
The right order for most service businesses is simple: a fast site or landing page built for lead capture first, tracking wired in, then ads to pour fuel on something that already burns.
Do your math with us
You now have the framework: job value, close rate, break-even cost per lead, likely cost per lead. If you want a second set of eyes on the arithmetic, bring us your numbers at sippicandigital.com/website-checkup and we will run the math with you, straight, including telling you if ads are the wrong move right now. Ten minutes on paper beats two thousand dollars of finding out the hard way.
