The quick verdict
Cold Facebook ads have $200-$500 nominal CAC per closed lawn-care subscriber — but real-margin CAC runs $400-$1,000 because Facebook can't target by route proximity. Mailed landscape quotes target by street, stacking new subscribers next to existing customers. Real-margin CAC: $80-$180 per closed subscriber. Route density is the entire game in lawn care, and Facebook can't optimize for it.
Side-by-side
| Metric | Mailed Landscape Quotes | Facebook Ads (cold) |
|---|---|---|
| Targets by street (route density) | Yes — core feature | No |
| Cost per home / click | $1 per quote | $1-$3 per click |
| Nominal CAC per closed subscriber | $80-$180 | $200-$500 |
| Real-margin CAC (accounting for route) | $80-$180 | $400-$1,000 |
| Subscription LTV captured | $1,400/yr avg + 3-yr retention | Same LTV but worse route economics |
The route-density math Facebook misses
Math on two new subscribers, both at $50/mow weekly:
- Mailed-quote subscriber (on existing route): 30-second drive between stops. Gross margin per mow: $28. Annual gross margin: ~$700.
- Facebook subscriber (12 miles from route): 22-minute drive between stops. Gross margin per mow: $11. Annual gross margin: ~$280.
Same subscriber, same per-mow price. But the Facebook subscriber generates $420 less per year. Over a 3-year LTV, that's $1,260 less gross margin. Even at the same nominal CAC, the Facebook subscriber is dramatically less valuable.
Where Facebook fits for landscapers
- Retargeting (warm audience). Anyone who scans a mailed quote enters a Facebook retargeting flow at $50-$150 CAC. These leads were already route-targeted because they came from your mailing.
- Snow plowing addon nurture. Existing mowing customers can be retargeted in fall with snow plowing creative.
- Design-install upsell. Mowing subscribers can be retargeted with mulch/hardscape creative.
Acquisition that targets by street, not by demographic.
