Customers compare prices with different inclusions
Explain diagnostics, labour, parts and taxes. An unqualified starting price creates enquiries that fail when the full quote arrives.

Fill workshop bays with profitable work
A workshop does not need calls from every driver. It needs repairs it can deliver, with parts available and space in its bays. We start with that capacity before buying traffic.

Quick answer
The essentials in one minute
Separate maintenance, faults and specialist repairs in Google Ads. Filter by location, vehicle make and service, and show when you can accept the car. Measure cost per paid repair and contribution rather than calls or quote requests alone.
Where money is lost and what to change
Small jobs take all the available slots
Separate quick services from longer repairs. Allocate spend using technician and bay hours as well as invoice value.
Enquiries concern work the shop cannot perform
State supported makes, systems and exclusions. Review parts, tutorial and job searches. Ask for model, year and symptoms without promising a diagnosis over chat.

What can you afford to pay for a customer?
Enter your own figures. Starting values explain the calculation; they are not market benchmarks or campaign results. Use amounts excluding VAT and the same reporting period throughout.
Clicks = spend / CPC. Enquiries = clicks × website conversion. Sales = enquiries × close rate, capped by capacity. Contribution per sale = revenue × margin. Result = sales × contribution - spend. Break-even excludes management fees, fixed costs and taxes; add these to your full plan.

Examples for better decisions
Fill workshop bays with profitable work
A workshop has spare capacity on Tuesdays while Fridays are fully booked. A maintenance campaign fills available slots. A separate specialist campaign measures accepted repair quotes. Jobs with different durations and margins no longer compete blindly for the same budget.
With 1,200 € in spend and 2.4 € per click, the model gives 500 visits. If 10% enquire and 45% of enquiries buy, it gives 22.5 paid repairs. Cost per enquiry is 24 € and cost per customer is 53.33 €. Revenue of 350 € at a 40% margin leaves 140 € per sale before advertising. The result after ad spend is 1,950 €.
The calculation uses starting values to explain the method. It is not a completed campaign or a promise of sales.
What changes when more enquiries become customers
Compare outcomes with the same spend and CPC. Improving close rate requires real changes to service, offer or availability; moving a percentage does not itself create sales.
Result after ad spend
1,950 €22.5 paid repairs
The sector economics worth checking
Calculate contribution per bay hour as well as per invoice. A €600 job occupying two days may be less attractive than several shorter services. Include parts, warranty work and the possibility of having to repeat a repair.
How we implement this in Google Ads and GA4
Choose the first service
Before building ads, we choose a service you can deliver at a sufficient margin. We review searches, coverage, price and the reason a customer would choose you. The first budget tests a specific proposition so the results can inform a decision.
Connect the ad and the page
The search, advertisement and first page section should describe the same service. Customers need scope, terms, availability and a clear next step. We separate services when intent, buying process or economics differ.
Measure different actions separately
In GA4 we distinguish interaction, contact opening and successful submission. The CRM adds quality, sales and loss reasons. Opening WhatsApp is not proof of a sent message or a customer. Only permitted data and conversions are imported when configuration and consent allow it.
Make decisions with enough evidence
We review search terms, ads, locations and the commercial progress of enquiries. A week without sales can be normal for a long purchase cycle; unanswered enquiries point to a different issue. We agree what evidence supports expansion, changes or stopping spend.
Build useful local information into the website
Explain actual service locations, access, opening hours and travel conditions in the customer’s language. Keep business details consistent with how you operate. A useful local page answers location-specific questions; repeating place names does not replace that information.

Questions business owners ask
What budget do we need to start?
It depends on click cost, conversion, contribution and capacity. Build an initial scenario with the calculator, then compare it with account data or planning estimates. Allow separately for management, the landing page and measurement.
How soon will customers arrive?
There is no universal timeframe. Launch depends on preparing the account, page, measurement and Google reviews. The service’s buying cycle then matters. Agree a review period long enough to assess both enquiries and sales.
Do we need a new landing page?
Not always. First check whether the current page explains the service, works on mobile and makes contact straightforward. A dedicated page is useful when search intent differs or essential decision information is missing.
Why is cost per form not enough?
Enquiries may be duplicates, unsuitable or never buy. Follow them through to sale and compare contribution. A more expensive enquiry can produce a more profitable customer.
Should we advertise urgent repairs?
Only if the shop can answer and accept the vehicle within the advertised time. Separate urgent work, limit hours and explain diagnostic or recovery charges. Unavailable appointments create calls without a good customer experience.
Should we use Search or Performance Max?
The choice depends on assets, measurement and objectives. Search can start with explicit intent. Performance Max needs appropriate signals and evaluation; it should not conceal missing commercial follow-up.
Can we restrict the service area?
Yes, using supported locations and exclusions. Review presence or interest settings for the business model. Location is inferred from signals and should be checked against actual enquiries.
How will we track WhatsApp outcomes?
Opening WhatsApp can be measured as an interaction, but it is not automatically a message or sale. The team records a valid conversation, proposal and outcome afterwards. Measurement must respect data and consent requirements.
Who keeps the account and data?
The proposal should specify account ownership and agency access. The business needs access to campaigns, spend, measurement and reports so it can understand and retain its history.
Will paid ads improve SEO or AI answers automatically?
Buying ads does not guarantee organic positions or AI mentions. A website needs helpful content, crawl access, consistent information and a clear structure. Advertising and organic visibility should be evaluated separately.

Method and documentation
Prepared by Contextera. General recommendations were checked against Google Ads Help on locations, qualified leads and advertising policies, and Google Search Central on helpful content and AI features. Requirements depend on the service and should be reviewed before launch.
