Unit Economics Deep Dive
Lead-level unit economics: P&L construction, CPL benchmarks by vertical ($15-$800), margin analysis by business model, and contribution margin by source. Most operators can't tell you what they earn on a single lead-that gap kills companies.
Chapter 33 addresses the fundamental gap that kills lead generation companies: operators who can't tell you what they actually earn on a single lead from their second-best traffic source in their third-highest-volume vertical. Without lead-level visibility, you might be scaling a traffic source that's hemorrhaging money, subsidized by profits from sources you've neglected.
Lead-level P&L construction requires decomposing your business economics to their smallest functional unit. Revenue recognition seems straightforward until you factor in return provisions. If your historical return rate runs 12%, that $50 sale isn't really $50-it's $44 in expected value. The return reserve should be calculated at the source-buyer level, not aggregate business level.
Direct costs trace directly to specific leads: traffic acquisition (often the largest expense), validation and verification fees ($0.50-$1.50 per fully validated lead for email, phone, identity, and consent documentation), and delivery costs. Allocated costs spread overhead across leads: technology allocation ($0.06-$0.08 per lead for mid-sized operations), labor (15-25% of costs), compliance reserves ($0.30 per lead if facing one TCPA demand letter per 50,000 leads).
CPL benchmarks by vertical as of late 2025 reveal enormous variation reflecting customer lifetime value, competitive intensity, and sales cycle complexity: auto insurance $15-$75, home insurance $20-$100, life insurance $25-$125, health insurance $30-$150, Medicare $30-$100, mortgage $25-$250, solar $30-$350, personal injury $100-$800, mass tort $50-$400.
Gross margin benchmarks by business position show structural differences: direct generators (owns traffic) achieve 60-80% gross margin, brokers (buys and resells) operate on 25-45%, networks (facilitate transactions) take 12-20% effective gross margin, and platforms (SaaS fees) achieve 85-95%.
Contribution margin by source reveals which channels profit versus which are subsidized. Most operators discover that 20% of their sources generate 80% of their profit. Run this analysis weekly-sources that were profitable last month may have deteriorated.
