From a funnel nobody could price to a measurable cost per customer
Before
The business was buying leads and closing sales, but it could not answer the two questions that decide whether paid media is a growth engine or a slow leak: what a new customer actually costs, and whether that customer is worth more than what it costs to acquire them. Spend, leads, and revenue lived in separate places. There was volume, but no line connecting a dollar in to a customer out, and no read on whether student lifetime value justified the acquisition cost.
The Radar
The diagnostic did one thing first: it rebuilt the funnel end to end so every dollar became traceable. That exposed the real unit economics instead of surface metrics. True cost per lead was $13.54, and once the funnel was measured through to closed sales, the real customer acquisition cost came out at $197 against a lifetime value that put the LTV:CAC ratio at 2.01. With the economics finally visible, the fix was structural, not cosmetic: a Lead Ads setup feeding a 1% Lookalike audience, so acquisition targeted the people who most resembled real buyers rather than the widest reachable pool.
After
- $13.54
- cost per lead, 1,485 leads
- $197
- customer acquisition cost
- 2.01
- LTV:CAC ratio
102 sales closed on $20,110 of spend, $40,377 in attributed revenue, and a 30% sales lift once the Lookalike 1% plus Lead Ads strategy went live. The account went from “we spend and we sell” to “we know what a customer costs, we know they are worth roughly twice that, and we know which lever moved sales up 30%.”
Takeaway
You cannot optimize what you cannot price. Making CAC and LTV:CAC visible turned guesswork into a repeatable engine.
