A lower cost per lead can be helpful, but it is not the same as a lower cost to acquire a customer. A form submission is one stage in a longer process that includes qualification, appointments, estimates and completed sales.
Our Instagram targeting reel discusses reducing lead cost. Courtesy Screening’s interview adds an equally important perspective: the people reaching out understood the work better. To evaluate marketing sensibly, put those two questions together: what does an inquiry cost, and what happens afterward?
Use consistent definitions and time periods
Agree on what counts as an inquiry, a suitable opportunity, an appointment held and a won job. Then compare groups that have had enough time to progress through your normal sales cycle.
Do not compare yesterday’s new inquiries with last month’s completed sales as though they had the same opportunity to close. Keep the date an inquiry arrived alongside its later status.
Calculate more than one cost
Use these simple calculations for a chosen group and reporting period:
- Cost per inquiry: Ad spend divided by inquiries.
- Cost per suitable inquiry: Ad spend divided by inquiries meeting your agreed criteria.
- Cost per appointment held: Ad spend divided by appointments that actually took place.
- Advertising cost per won job: Ad spend divided by jobs won from that group.
The last measure includes advertising spend only. It is not your full customer-acquisition cost unless other relevant acquisition costs are also included and labeled.
See why the cheapest lead can mislead
Consider this hypothetical comparison. These are teaching numbers, not BVS client results:
| Measure | Campaign A | Campaign B |
|---|---|---|
| Ad spend | $1,000 | $1,000 |
| Inquiries | 100 | 50 |
| Suitable inquiries | 10 | 20 |
| Cost per inquiry | $10 | $20 |
| Cost per suitable inquiry | $100 | $50 |
Campaign A produces cheaper inquiries. Campaign B produces cheaper suitable opportunities. You still need appointments and sales data before deciding which campaign is better for the business overall.
Separate revenue from profit and cash collected
Contracted work, money received and profit answer different questions. In Courtesy Screening’s source material, the reported result is contracted revenue. Do not quietly convert that into cash collected or profit.
For your own reporting, label each measure accurately and include the period. A signed project may have costs still to come, and a long project may collect payments over time. Ask the business’s financial owner to confirm the definitions used in performance reports.
Give campaign reviews real customer feedback
Add the most common reasons inquiries did not progress: outside area, wrong service, unable to contact, timing, or another documented reason. That helps distinguish a messaging problem from a follow-up problem.
For businesses ready for a technical integration, Meta describes using CRM outcomes with its Conversions API to optimize for qualified leads. That requires a properly implemented connection and suitable data; changing a label in a spreadsheet alone does not create it. Meta’s training explains the concept.
Start with a weekly review of one consistent group of inquiries. Look at cost, fit and progression together. Choose the largest documented gap and assign a specific improvement before increasing spend.
