IS GOOGLE ADS WORTH IT? DO THE MATH FIRST.
A simple 3-number test that tells you whether Google Ads will make you money, with real-world examples, the lifetime value most people forget, and when it's honestly not worth it yet.
"Is Google Ads even worth it?" Usually asked by someone who tried it once, spent $600 and got two calls from people who wanted a free quote and a discount. I get it. If that was my experience, I'd be skeptical too.
But "worth it" isn't a feeling. It's math. And the math is simple enough to do on the back of a Tim Hortons napkin. Let's do it together.
The quick answer
- Google Ads is worth it if what a customer is worth is comfortably more than what it costs to win one.
- You need three numbers: average job value, close rate and cost per lead.
- Repeat customers and referrals make it even more worth it.
- It's not worth it yet if you can't answer the phone or don't have tracking set up.
Section 01The 3-number test
Grab these three numbers. Rough is fine.
- Average job value: what a typical new customer pays you.
- Close rate: out of every 10 leads, how many become paying customers?
- Cost per lead: what you'd pay Google per call or form. If you don't know yet, use your industry's range from What Google Ads Actually Costs.
Now compare that to what the customer is worth, after your costs. If winning a customer costs a small slice of your profit on the job, Google Ads is a money machine. If it eats the whole profit, it's not, at least not the way it's set up right now.
Section 02Let's run some real-world examples
| Business | Job | Close | Per lead | Per customer |
|---|---|---|---|---|
| Junk removal | $450 | 1 in 2 | $45 | $90 |
| Plumbing (repair) | $600 | 1 in 3 | $90 | $270 |
| Roofing (replacement) | $12,000 | 1 in 5 | $250 | $1,250 |
| Personal injury law | $15,000+ fee | 1 in 10 | $200 | $2,000 |
Example numbers to show the math, not promises. Your real numbers depend on your market and setup.
Look at roofing. $1,250 to win a customer sounds scary until you remember the job is $12,000. That's one of the best deals in business. Meanwhile, a $90 cost per customer on a $450 junk job is also great, especially if your crew has the time.
Now the counter-example: say you sell a $60 service and close 1 in 5 leads at $40 each. That's $200 to win a $60 customer. No amount of ad wizardry fixes that. You'd need repeat business, a higher-value offer or a different marketing channel.
Corny joke break
Doing the math before running Google Ads is like checking the price before ordering the lobster.
Nobody likes surprises when the bill comes. Especially not the lobster.
Section 03The part most people forget: lifetime value
A lot of service businesses don't just win a job. They win a customer. Pest control comes back every season. HVAC customers need maintenance every year. A happy cleaning client might book you twice a month for years. And happy customers send referrals.
So if a customer is worth $300 on the first job but $1,500 over three years, you can afford to pay a lot more to win them than your competitors think. That's how smart businesses outbid everyone and still make more money.

Section 04When it's not worth it (yet)
I'd rather tell you this now than take your money. Google Ads probably isn't worth it yet if:
- You can't answer the phone during business hours and don't have a plan for it.
- You don't have tracking, so you'll never know what's working.
- Your website is a disaster on mobile and there's no landing page.
- You're already fully booked and can't take more work. (Congrats. Raise your prices.)
- Your budget can only buy a couple of clicks a day and you want to cover five services in ten cities.
Fix those first, and Google Ads goes from "maybe" to "why didn't I do this sooner."
Pano's take
Every client I work with, I start with this exact math. If the numbers don't work, I'll tell you. I'd rather lose a sale than take money from a business that's set up to lose it on ads.
FAQQuick answers
Is Google Ads worth it for a small business?
It's worth it when the profit from a customer is comfortably more than the cost to win one. Work out your average job value, close rate and cost per lead. If the cost to win a customer is a small slice of your profit, it's worth it.
What is a good return on Google Ads?
It depends on your margins, but many service businesses aim to bring in several dollars of revenue for every dollar of ad spend. Repeat customers and referrals make the real return even higher.
Why didn't Google Ads work for me before?
The most common reasons are poor settings, broad or irrelevant keywords, no landing page, broken tracking and missed calls. Most of these are fixable, so one bad experience doesn't mean it can't work.
