Be findable where people look
Most owners search on their phone with a problem and a suburb: "brakes grinding Henderson", "mobile mechanic Albany". A complete Google Business Profile with your real service area, hours and photos is the baseline. Listing on platforms that publish per-suburb pages adds more places to be found.
Reviews from real jobs
Ask every happy customer for a review the day the job is done, and reply to every review, good or bad. Reviews tied to completed work carry more weight with customers than star ratings alone.
Specialise in what you do best
Owners trust specialists. If you are strong on diagnostics, Euro vehicles, diesels or hybrids, say so everywhere. Specific profiles win specific jobs.
Quote clearly
An itemised quote (parts, labour, what is included and what would change it) wins against a single number, and it reduces arguments later.
Respond fast and follow up
Owners often contact several businesses. A quick, clear reply and a follow-up message after the job builds repeat work and referrals.
Watch what each lead costs
Per-lead and commission models charge you whether or not the job was a good fit. A flat monthly fee makes cost per job fall as you win more.
