Is Google Ads worth it for small business owners like plumbers, electricians, cleaners or dentists? It is when three things hold: people in your area search for the job you do, the profit on a booked job covers what Google charges for the clicks it takes to win one, and you can answer the phone when those clicks turn into calls. If any of the three fails, you’ll pay for clicks that never become work, which is the complaint that opens the most-answered Reddit thread on this question.
You can check all three before you spend anything. Below are the follow-up questions owners ask on Reddit and in Google’s “People also ask” box, with the sums and settings that answer each one for your own business. Example figures are marked as examples. Your numbers will be different, and they’re the only ones that matter.
Is Google Ads worth it for small business? How to work out if it will pay for itself
Work backwards from the profit on one job to the most you can pay for a click, then compare that with what clicks actually cost for your searches. On Search campaigns you pay for each click on your ad, so the click price is where the maths starts.
- Profit per job. Take the average invoice and subtract materials and labour. Use profit, because a $400 job that leaves you $200 can’t carry $300 of advertising.
- Most you’d pay to win one job. Decide what share of that profit you’re willing to spend on getting the job. If the customer tends to come back or refer others, you can afford more; our guide to customer lifetime value shows how to count that.
- Your close rate. Out of every enquiry, how many become booked jobs? Check your last few months of calls and forms.
- Most you’d pay per lead = most you’d pay per job × close rate.
- Your lead rate. How many visitors from an ad call or fill in the form. Before you have data, pick a cautious guess and replace it with your real figure once ads run.
- Most you’d pay per click = most you’d pay per lead × lead rate.
- Compare with real click costs. In your Google Ads account, go to Tools, then Keyword planner. Enter the searches your customers use and your area. Keyword Planner estimates monthly searches and the average cost for your ad to show on each one, and can forecast clicks and conversions for a daily budget. (You need to finish account setup and add billing before it works.)
Worked example: an electrician (example figures)
| Step | Small jobs (call-outs, repairs) | Bigger jobs (switchboard upgrades) |
|---|---|---|
| Average invoice | $400 | $1,500 |
| Profit per job | $200 | $600 |
| Most you’d pay to win the job (half the profit) | $100 | $300 |
| Close rate (1 in 3 enquiries booked) | 33% | 33% |
| Most you’d pay per lead | $33 | $100 |
| Lead rate (1 in 10 visitors call or enquire) | 10% | 10% |
| Most you’d pay per click | $3.30 | $10.00 |
Now say Keyword Planner shows clicks costing around $8 for the searches this electrician wants. Small jobs don’t work at that price: every booked repair would cost more than the profit you set aside for it. Switchboard upgrades do work, with room to spare. So the answer to “is it worth it” here is yes, for one kind of job, and the campaign should be built around those searches with the small-job keywords left out or bid low.
Two numbers in the chain are in your control. Doubling the lead rate from 10% to 20% doubles the click price you can afford, and that comes from the page the ad sends people to (see our landing page diagnostic). A better close rate does the same, and that comes from answering the phone quickly and calling back missed calls. If the clicks are coming but the calls aren’t, our guide to Google Ads clicks with no calls lists what to check.
How much should a small business spend on Google Ads?
Spend enough to get enough leads in a month or two to judge the result, and no more until the numbers say it’s working. You can work that figure out:
Test budget per month = leads you want to judge on ÷ lead rate × cost per click.
Example: you want 10 leads before deciding, your lead rate is 10% and clicks cost $5. That’s 100 clicks, so $500 a month. Google budgets are set per day, as an average daily budget, and Google’s monthly cap is 30.4 times that figure for most campaigns. So $500 a month is about $16.50 a day. On a single day Google can spend up to twice the daily budget, which is normal, but over the month it won’t charge more than 30.4 times the daily budget.
If the budget you’re comfortable with buys fewer clicks than it takes to get a lead a week, narrow the campaign to one service and the towns closest to you. A small budget spread over everything you do won’t get enough clicks on any one service to show you anything.
For heating and cooling companies, see our guide to Google Ads budgets for HVAC companies.
Is $20 a day enough for Google Ads?
It can be for one service in one area, if your clicks are cheap enough. At $20 a day the most Google will charge in a month is $608 (30.4 × $20). At an example $5 a click, that’s about 120 clicks; at a 10% lead rate, about 12 leads; at a 1 in 3 close rate, about 4 booked jobs. Whether 4 jobs a month is worth $608 depends on the profit per job you worked out above.
If clicks for your trade cost $15 in your city, the same $20 a day buys about 40 clicks and 4 leads, which is too few to tell a good month from bad luck. That’s when you either raise the budget, cut back to your most profitable service, or look at Local Services Ads instead.
Should I use Local Services Ads or Google Search ads?
If your trade is covered by Local Services Ads in your country, try them alongside Search ads, because they charge per lead and Search ads charge per click. Local Services Ads are only available for certain service categories, which include home services such as plumbers and electricians and health providers such as dentists, and availability varies by country and area.
| Google Search ads | Local Services Ads | |
|---|---|---|
| What you pay for | Each click on your ad | Leads: you pay when a customer gets in touch from your ad, for leads related to the services you offer |
| Who can use it | Any business that meets Google’s ad policies | Only certain service categories, in the areas where Google offers them |
| Trust badge | None | Google Verified badge for businesses that pass Google’s screening (where offered) |
| Targeting | You choose the keywords, locations and ad schedule | Highly targeted by location |
| Main risk | Paying for clicks that never call | Paying for leads that turn out not to be a fit |
| Best fit | Jobs where you need control over which searches you pay for, or trades Local Services Ads don’t cover | Trades in covered categories that mostly win work by phone |
Google’s own comparison for small businesses puts it the same way: with Search ads you pay each time someone clicks, and with Local Services Ads you pay only when a customer contacts you directly by phone, text or email. The break-even maths above still applies to Local Services Ads. Use the “most you’d pay per lead” figure and compare it with what you’re charged per lead. For roofing figures, see what a good roofing Google Ads cost per lead is.
Why do so many small businesses say Google Ads doesn’t work?
Usually because the account pays for the wrong clicks and nobody measures the calls. These are the setup problems to check, each with its fix:
| Mistake | What it costs you | Fix |
|---|---|---|
| No call tracking | You judge the ads on clicks and can’t see which ones bring calls | Set up phone call conversion tracking for calls from ads and calls to the number on your website, with a minimum call length so short calls don’t count |
| Paying for searches you don’t want | Clicks from people looking for jobs, DIY help or free advice | Every week, open Campaigns, then Insights and reports, then Search terms, and add the wrong ones as negative keywords |
| Ads showing outside your area | Calls from towns you don’t travel to | In your campaign’s location options, choose “Presence” so ads reach people in your areas. Google recommends “Presence or interest” for Search, which also reaches people outside your areas who’ve shown interest in them; a trade that only works locally usually wants “Presence” |
| Ads running when nobody answers | Paid clicks that hit voicemail | Set an ad schedule to the hours someone picks up the phone |
| Small budget spread over every service | Too few clicks per service to learn anything | Start with your most profitable job and closest towns, then add more once it pays |
| Every ad goes to the home page | Low lead rate, which lowers the click price you can afford | Send each service’s ads to a page about that service, with the phone number at the top |
Location settings are explained in Google’s help page on targeting ads to geographic locations. Once the account tracks calls, the bid strategy question comes next; for low-volume accounts we’ve written up Manual CPC or Target CPA separately.
When is Google Ads not worth it for a small business?
When the problem is something ads can’t fix. Hold off, or fix the gap first, if any of these is true:
- You’re already booked up for weeks. More leads will just go to a competitor while they wait for you.
- Nobody can answer the phone in the hours the ads would run.
- Keyword Planner shows very few searches for your service in your area.
- Click costs for every service you offer are above the “most you’d pay per click” figure, even for your best jobs.
- You have no way to tell which calls came from the ads, so you’d be judging on gut feel.
- Your website has no page for the service you’d advertise and no clear phone number.
If none of these apply and the maths works for at least one service, Google Ads is worth testing with a budget sized by the formula above.
If few people search for your service because customers plan it weeks ahead, such as remodels or roof replacements, Facebook ads may be the better first test. Our answer to do Facebook ads work for contractors sorts jobs by how well they fit. If you go that way, our comparison of Facebook lead ads vs a landing page covers which one brings better enquiries.
Should I run Google Ads myself or pay someone?
Run it yourself if you’ll spend time every week in the search terms report and you can set up call tracking properly. Pay someone when your hours are worth more on the tools than at a desk, or when the account spends enough that a month of wasted clicks costs more than the management fee. If you already pay someone, here is how to know if your Google Ads agency is doing a good job.
Whoever runs it, ask for the same things: the account in your name with admin access, call tracking that counts real calls, and a monthly report that shows leads and booked jobs. If you want a specialist to set it up, our Google Ads management for trades and local service businesses starts with two months of management free. You still pay Google directly for your ad spend. We also have pages for plumbers and electricians.
FAQ
Is $1 a day good for Google Ads?
No, not for a service business. A $1 average daily budget caps your month at about $30. At an example $5 a click, that’s 6 clicks, which may not bring a single lead. You won’t learn whether Google Ads works from that, so it’s better to run a properly sized test on one service.
Is $10 a day enough for Google Ads?
It’s enough only if clicks for your service are cheap. Google’s own example shows a $10 daily budget works out to about $304 a month. At an example $5 a click that’s around 60 clicks, so with a 10% lead rate you’d expect about 6 leads a month.
Are Google Ads still worth it in 2026?
The question is the same as any year, because Search ads still charge per click. Check today’s click costs for your searches in Keyword Planner and run them through the break-even steps above. If the cost per click you can afford is above what Keyword Planner shows, it’s worth testing.
What is the minimum amount to spend on Google Ads?
You set your own average daily budget. The useful minimum is the amount that buys enough clicks to get the number of leads you need to judge results, which is leads wanted ÷ lead rate × cost per click.
