What a brake job Google Ads campaign costs a repair shop, and when it pays back
A line-by-line look at a small Google Ads campaign built around brake jobs: budget, cost per call, close rate, and the point where it starts paying for itself.
Most shop owners who try Google Ads run one broad campaign for "auto repair," spend a few hundred dollars, get a pile of oil change shoppers and price checkers, and decide ads do not work. The problem is usually not Google. It is that the campaign was not aimed at a job worth paying for.
Brakes are one of the better places to start. Drivers who search "brake repair near me" usually have a noise, a warning light, or a pedal that feels wrong. They need it fixed soon, and a typical brake job is a solid ticket. Here is what a small, focused brake campaign costs and how to tell when it has paid for itself.
The pieces and what they cost
Every number below is a range or a hypothetical. Your market, your rates and your competition will move them.
Ad spend. A small single-service campaign in a mid-size market often runs $20 to $40 a day. Call it $600 to $1,200 a month.
Cost per click. Brake and auto repair clicks commonly land somewhere between $4 and $12, higher in big metros. At $8 a click, $900 a month buys about 110 clicks.
Setup. If you build it yourself, it costs a few evenings. If you hire help, a one-time setup is often a few hundred dollars, and ongoing management commonly runs $300 to $800 a month. The agency guide covers what fair looks like.
Call tracking. Google can count calls from the ad itself for free. A separate tracking number tool, if you want recordings, usually runs $20 to $50 a month.
A hypothetical month
Here is how $900 in spend might play out for a single shop:
| Step | Number |
|---|---|
| Clicks at about $8 | 110 |
| Calls or form requests (about 1 in 6) | 18 |
| Answered and quoted | 15 |
| Booked into a bay | 8 |
| Average brake ticket | $450 |
| Revenue | $3,600 |
On paper that is $3,600 in work from $900 in spend. But revenue is not profit. If your gross margin on brake work is around 50%, that month made about $1,800 in gross profit against $900 in ads. Add $500 in management and you are at roughly $400 ahead.
That is a thin first month. The payback gets better from the second visit on.
Where the real payback comes from
A new customer who trusts you with their brakes often comes back for tires, fluids, an alignment, and the next inspection. If one of those eight customers turns into a regular worth $800 a year, the campaign math changes a lot.
Put your own numbers into the calculator. The question is not whether month one was profitable. It is how many new regulars the campaign brought in and what they are worth over two or three years.
The four things that decide whether it works
1. Answer the phone. The single biggest leak in shop ad campaigns is calls that ring out while the service writer is with a customer. If 4 of those 18 calls go to voicemail, you paid for them and got nothing. Set up a text-back so missed callers hear from you within a minute. The missed calls guide covers how.
2. Send clicks to a brake page. Do not send brake searches to your home page. Send them to a page that says brake repair, shows your warranty, shows your hours and has a tap-to-call button at the top. In our data on 90,000 repair shops, 44.3% have no website at all, which means no landing page for ads either. The website guide lays out what that page needs.
3. Block the junk. Add negative keywords like "DIY," "how to," "parts," "pads only," and "free." You do not want to pay for someone looking for a parts store or a video.
4. Keep the radius tight. Most drivers will not go far for brake work. Start with a radius you would actually drive to pick up a car, often five to ten miles.
When to stop or change it
Give the campaign at least 60 days. The first few weeks are noisy while Google learns.
At 60 days, look at booked jobs, not clicks. If the campaign brought fewer booked brake jobs than it would take to cover spend at your margin, look at the call recordings before you blame the ads. Unanswered calls and price-shopping quotes fix differently than bad keywords. The Google Ads guide goes deeper on campaign structure.
Reviews make every click cheaper
A driver who clicks your ad will look at your reviews before calling. The median repair shop has 44 Google reviews, and the top 10% have 343 or more. If you are well below the median, ad clicks convert worse because the comparison on the map hurts you. The benchmark report shows where your shop stands.
