Measure the chimney marketing funnel
Do not blend every inquiry together. Routine sweeping, inspection, estimated repair, masonry, an unserviceable location, and a service the company does not offer have different commercial value.
Separate chimney cost-per-lead definitions
| Metric | Formula | Decision |
|---|---|---|
| Cost per inquiry | Spend ÷ attributable calls and forms | Capture cost |
| Cost per qualified lead | Spend ÷ eligible service opportunities | Traffic and intake quality |
| Cost per booking | Spend ÷ attributable booked appointments | Marketing plus office execution |
| Cost per completed service | Spend ÷ completed attributable appointments | Acquisition cost |
| Return on acquisition spend | Attributable contribution ÷ acquisition spend | Economic output |
What changes chimney sweep marketing cost?
- Routine, inspection, repair, masonry, cap, liner, and commercial mix
- Core and extended territories, travel time, and route density
- Seasonal demand, weather, local usage, and customer lead time
- Phone answer, form response, booking, cancellation, and completion rates
- Technician skills, equipment, access, and appointment duration
- Average revenue, variable fulfillment cost, callback, and warranty burden
- Channel competition, reviews, page quality, and attribution coverage
Use the chimney lead-generation framework to define qualification before comparing sources.
Calculate allowable chimney sweep CPL
Completed-service contribution before acquisition = collected revenue − variable field labor − materials and equipment cost − payment and fulfillment cost − expected callback burden
Allowable cost per completed service = contribution before acquisition × acquisition share the company can support
Allowable cost per qualified lead = allowable completed-service cost × qualified-lead-to-completion rate
If average contribution before acquisition is $180, the business can allocate 20% to acquisition, and 60% of qualified leads become completed services, the implied ceilings are $36 per completed service and $21.60 per qualified lead. These are not market benchmarks. Replace every input with current company data and separate materially different services.
Build the chimney marketing budget from capacity
| Input | Planning use |
|---|---|
| Open appointment slots | Sets demand capacity by week |
| Qualified-to-booked rate | Converts leads into schedule demand |
| Booking-to-completion rate | Adjusts for cancellations and operational leakage |
| Service contribution | Sets allowable acquisition cost |
| Route density | Changes field productivity and cost |
| Seasonal lead time | Determines when to build or reduce demand |
Use the broader local-service marketing budget model. Increase spend before open capacity disappears, not after the schedule is already overloaded.
Report chimney marketing ROI by service and cohort
Store source, service, ZIP, qualified status, booking, completion, additional authorized work, collected revenue, variable cost, contribution, and outcome reason. Use the local-service attribution guide to connect the records.
Marketing ROI = (attributable contribution after acquisition − acquisition spend) ÷ acquisition spend
Attribution coverage = comparable completed services with usable source ÷ all comparable completed services
How this chimney cost model works
This is a company-specific operating model, not a published universal benchmark. It deliberately distinguishes inquiry, qualified lead, booking, completion, realized revenue, and contribution. Values should come from the company’s current advertising, phone, booking, field-service, and accounting records.
A 30-day cost and ROI audit
- Define inquiry, qualified lead, booking, completion, additional work, revenue, and contribution.
- Reconcile marketing, call, form, schedule, invoice, and payment records.
- Segment outcomes by service, territory, source, and season.
- Calculate actual funnel rates and contribution.
- Set allowable costs for material service groups.
- Reallocate budget while monitoring schedule and route capacity.
