How an insulation campaign turned $34K in ad spend into approximately $400K in revenue.
This case study shows why insulation marketing should be measured beyond cost per lead. The campaign operated around a $50–$80 CPL and roughly $200 cost per appointment while generating approximately $400,000 in revenue from about $34,000 in ad spend.
Quick answer
The insulation campaign spent about $34,000, generated leads at approximately $50–$80 each, produced appointments at roughly $200 each and generated about $400,000 in revenue. That is approximately 11.8× revenue-to-ad-spend.
The challenge
The business needed a more predictable flow of qualified insulation opportunities without relying on inconsistent lead sources. The goal was not simply to lower CPL, but to create appointments that could turn into profitable jobs.
The acquisition strategy
Paid campaigns were paired with focused lead capture, qualification and fast follow-up. Performance was evaluated on appointment cost and revenue, not raw form submissions alone.
- Cost per lead: $50–$80
- Cost per appointment: about $200
- Total ad spend: about $34,000
- Revenue generated: about $400,000
- Revenue-to-ad-spend: about 11.8×
Why the economics worked
A $50–$80 lead can still be highly profitable when lead quality, appointment setting and sales follow-up work together. The strongest metric was not the cheapest lead; it was the cost of producing a real sales opportunity.
What insulation companies can learn from this
Track cost per appointment, lead quality and closed revenue alongside CPL. A campaign that looks expensive at the top of the funnel can still outperform when downstream conversion is strong.
How to interpret these results
Cost per lead means ad spend divided by captured inquiries. Cost per appointment measures a later funnel outcome, so it should not be compared directly with CPL. Compare appointment costs only when the booked-versus-attended definition and attribution window are consistent. The approximately $400,000 figure is attributed revenue, not gross profit. It does not subtract ad spend, agency or software fees, labor, materials, fulfillment or other operating costs. The 11.8× figure is therefore a directional revenue-to-ad-spend ratio, not a profit multiple or a guaranteed return.
What can change insulation campaign performance?
Results can vary with market demand, seasonality, weather, service mix, average job value, the energy-efficiency offer, response speed, scheduling capacity and the sales process. A contractor should confirm that the team can contact, qualify and serve additional inquiries before increasing spend.
What to track after the form submission
Separate valid inquiries from duplicates, spam and out-of-area requests. Then track contact rate, qualified opportunities, booked and attended estimates, sold jobs and attributed revenue. Keep open estimates in a mature sales cohort rather than counting them as losses too early, and use the same attribution window across sources. For profitability analysis, compare fully loaded acquisition cost—including media, agency and software costs—with gross profit after cancellations and refunds. This makes it easier to see whether the constraint is media, lead quality, follow-up, appointment attendance, closing or job economics. Use the contractor lead qualification framework to define consistent stages, the measurement framework to evaluate mature cohorts, and the benchmark calculator to model the economics. Compare this result with the other contractor marketing case studies.
