Google Ads vs Facebook ads for auto repair shops: which should you run?

Are Google Ads or Facebook ads better for a mechanic shop?

Google Search ads can reach people actively searching for a repair. Facebook and Instagram ads can introduce a local offer to people who are not searching at that moment. Choose based on the service, the shop's capacity, and its ability to follow up. Judge either channel by completed jobs, not lead volume alone.

This is a decision framework, not a claim that one platform always produces cheaper customers. Search demand, competition, creative quality, travel distance, and response handling differ by shop.

Choose the job before the channel

Write down one service you want more of, the vehicles you can handle, the area customers realistically travel from, and how many additional appointments you can accept. Decide what the first visit actually promises. “Book a diagnostic visit” is a different offer from a guaranteed repair quote.

A focused Google Ads test

Group ads by actual service intent rather than sending every search to the homepage. Review search terms and exclude irrelevant demand such as jobs, training, free DIY instructions, or services you do not offer. Choose location settings deliberately; check the current platform options before launch.

Send a brake-repair search to a brake-repair page with your location, process, and contact options. Keep call-focused advertising aligned with when someone can respond, or provide a working after-hours process. Track meaningful calls and requests, then reconcile them with bookings and completed work.

A focused Facebook ads test

Use real shop photos or a short explanation from the team. State the service, location, terms, and next step clearly. A broad discount that attracts work the shop cannot profitably perform is not a good result just because leads are cheap.

For lead forms, collect only what is needed to continue: contact details, the requested service, and enough context to determine fit. Explain how the shop will contact the person and honor that expectation. Test the full path yourself before spending: submission, notification, response, appointment offer, and confirmation.

Compare the economics honestly

Use your own numbers. In an illustrative example, $600 in ad spend producing 30 inquiries, 12 bookings, and 8 completed new-customer jobs means $20 per inquiry, $50 per booking, and $75 in ad spend per completed new-customer job. Management fees and creative costs are additional acquisition costs.

Compare contribution after parts, labor, discounts, and acquisition cost rather than counting the full repair invoice as profit. Separate returning customers from first-time customers. A low-cost inquiry is useful only if it becomes work worth doing.

Where Sapt fits in an advertising plan

Sapt's $297/month managed website, Google listing, missed-call texting, and AI booking help handle the demand the shop receives. Ad spend and campaign management are separate. Fix the missed-call process before paying to generate more calls, and use the marketing plan to compare paid and unpaid sources.
