Urgent promises exceed available slots
Show real availability and limit repair campaigns to serviceable locations. Do not advertise immediate service when the first slot is days away.

Installations and repairs that fit your team capacity
During a heatwave, demand can exceed staffing. Outside peak season, the opposite happens. Advertising should balance installation, repair and maintenance around capacity and contribution.

Quick answer
The essentials in one minute
Separate installation, fault repair and maintenance campaigns. Explain service area, availability, installation scope and pricing conditions. Evaluate completed jobs after equipment, materials and travel. Seasonality calls for changes to offers and budgets, not just higher bids.
Where money is lost and what to change
The quote changes on arrival
Explain standard installation inclusions and what needs assessment. Collect relevant property details through an appropriate channel before confirming the total.
Enquiries disappear outside peak season
Plan maintenance, replacement and genuinely offered services. Compare equivalent periods rather than every month with the summer peak.

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
Installations and repairs that fit your team capacity
A company has two installers and four weekly slots. In peak heat it reduces new-installation acquisition when booked out while retaining repair campaigns where it can respond. In quieter months it tests maintenance with a dedicated offer and page.
With 1,500 € in spend and 2.5 € per click, the model gives 600 visits. If 8% enquire and 35% of enquiries buy, it gives 16.8 completed jobs. Cost per enquiry is 31.25 € and cost per customer is 89.29 €. Revenue of 900 € at a 35% margin leaves 315 € per sale before advertising. The result after ad spend is 3,792 €.
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
3,792 €16.8 completed jobs
The sector economics worth checking
Deduct equipment, materials, labour, travel and warranty visits. A high-value installation may contribute less than several nearby maintenance jobs. Use weekly capacity as a growth constraint.
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.
How should we advertise a starting installation price?
Define the equipment and included conditions, plus circumstances requiring a separate quote. Do not present a complex installation as standard. Confirm scope before booking.
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.
