Auto repair is one of the best performing categories in all of Google Ads, and there is confirmed data to prove it. Automotive repair, service and parts averages a 15.51% conversion rate and a $29.96 cost per lead, against an all industry average of 8.18% and $66.69.
That is roughly double the conversion rate at under half the cost per lead. Those figures come from a study of 13,474 US search campaigns run between April 2025 and March 2026.
The reason is simple. A car problem is urgent, local and non negotiable. Nobody researches a broken alternator for three weeks.
What the benchmarks mean for your shop
| Metric | Automotive repair | All industries |
|---|---|---|
| Click through rate | 5.56% | 6.64% |
| Conversion rate | 15.51% | 8.18% |
| Cost per lead | $29.96 | $66.69 |
What this means for you: at around $30 a lead, the arithmetic works at almost any ticket size. A $400 average repair order against a $30 lead and a 50% booking rate gives you a $60 acquisition cost on a $400 job. The constraint on most shops is bay capacity, not lead cost.
That changes the goal. You are not trying to buy as many leads as possible. You are trying to buy the right ones to fill the bays you actually have. Our cost per lead benchmarks put automotive next to other categories.
Fill the profitable bays, not just the bays
This is specific to a shop and it is where the money is.
An oil change and a transmission rebuild both occupy a bay. One earns a fraction of the other. If you run every service in one campaign with one target, Google will fill your schedule with the cheapest conversions, which are usually the lowest margin jobs.
Split by job value:
- Diagnostics and repair, where the value is unknown at booking but usually good. This is your core.
- High ticket work like transmission, engine or AC systems. Own campaign, own budget.
- Routine servicing, which fills gaps and builds a customer base but should not consume the budget.
- Tyres and quick fit, if you do them, which are price driven and behave differently again.
Then judge each on revenue per booking, not on cost per lead.
Auto repair is a phone and walk in business
Most enquiries are calls. Many are people who will simply drive over. Neither shows up as a form submission.
- Track calls as conversions, with call assets and tap to call on mobile.
- Use a duration threshold so wrong numbers do not count as leads.
- Send completed repair orders and their values back into Google Ads so bidding learns which calls became work.
That last step separates shops that scale from shops that plateau. At a 15.51% conversion rate you will get plenty of calls. Knowing which ones became a $900 job is what lets you bid harder for more of those. From 15 June 2026 Google moved offline conversion imports to the Data Manager API and blocked them in the Google Ads API, so check any older integration from your shop management software. Our guide to conversion tracking covers the setup.
Local Services Ads and the local pack
Auto care is among the categories Google lists as eligible for Local Services Ads, so it is worth checking availability in your market.
One current detail: Google discontinued the Google Guarantee badge and its money back guarantee, replacing it with a single Google Verified badge, with reimbursement claims closed on 7 December 2025. Our comparison of Local Services Ads and Google Ads covers running both.
Worth saying plainly: for a local shop, your Google Business Profile and reviews do a great deal of the work for free. Get that right first. Ads buy visibility above it, not instead of it.
The negatives that matter in auto repair
Automotive search volume is dominated by people diagnosing problems themselves and by parts shoppers.
- DIY. How to fix, replace, symptoms of, why is my car, warning light meaning.
- Parts. Part numbers, brand names, prices, unless you sell parts over the counter.
- Buying and selling cars. Used cars, valuations, dealerships, unless you also trade.
- Careers. Mechanic salary, apprenticeship, courses, ASE certification.
- Free. Free diagnostic shoppers who go elsewhere for the work, unless that is a deliberate funnel.
Set location targeting to presence rather than presence or interest. A shop has a drivable radius and the default setting ignores it. Our post on negative keywords covers building the list.
How to choose an agency for an auto shop
- “What conversion rate should we expect?” They should know automotive benchmarks sit around 15%, not 8%. If they quote the all industry average, they have not looked.
- “How will you separate high ticket work from oil changes?” One campaign fills bays with the wrong jobs.
- “How will repair order values get back into the account?” Call counts are not enough.
- “What is our bay capacity and how does that change the plan?” An agency that never asks is selling volume you cannot service.
- “What would make you tell us to stop?” No answer means they are selling.

Common questions
How much should a shop spend?
Work back from bays. Decide how many extra jobs a week you can physically take, divide by your booking rate, and multiply by roughly $30 a lead. Most single site shops need less than they expect.
Why is our conversion rate lower than 15.51%?
Usually call handling, or a landing page that does not show a phone number and opening hours immediately. The benchmark assumes someone picks up.
Should we advertise oil changes?
As a customer acquisition play, yes, if you measure what those customers are worth over a year. As a profit centre on their own, rarely.
Do we need a website?
For Search ads, yes. It does not need to be large, but it needs your phone number, hours, location and the services you actually do, above the fold. Our post on high converting landing pages covers what belongs on it.
How long before it works?
Faster than most categories. Calls usually start in the first week. Judge the economics at ninety days on repair order value, not lead count.
Where to go from here
One check. Take last month’s ad spend, divide by the number of repair orders that came from ads, and compare that to your average repair order value. In this category that ratio is usually far better than shop owners assume, and the real constraint turns out to be capacity.
