The Lead Economics Launch Decision Rule evaluates advertising through cohort economics rather than conversion rate alone. First, divide acquired leads into cold prospects and previously engaged audiences. For each cohort, calculate cost per lead, immediate sales, earnings per lead, average customer value, and the typical delay before purchase. A lower initial conversion rate can still be attractive when acquisition costs are low and customer lifetime value is high. Leads who do not purchase in the current launch remain assets if the business can nurture them into later conversions. The resulting economics inform whether to acquire cold traffic during a launch, build the list earlier when costs are lower, or concentrate launch spending on warm retargeting audiences.
Origin
Extracted from The Jasmine Star Show as Rick Mulready evaluated whether Social Curator should stop paid launch lead generation based on its lower initial conversion rate.
Core principles
- 01Conversion rate alone cannot determine whether paid acquisition works
- 02Cold and warm leads should be evaluated separately
- 03Lifetime value matters more than first-month revenue
- 04Delayed conversions belong in cohort economics
- 05Acquisition timing should reflect both costs and the nurture period
How to run it
- 1
Split the acquisition cohorts
Separate first-time cold leads from warm viewers, existing subscribers, and other retargeted audiences.
Pro tip Preserve campaign and source tags so each cohort can be followed through purchase.
Watch out A blended conversion rate can hide major differences between cold and warm traffic.
- 2
Calculate cost per lead
Divide the advertising spend for each cohort by the number of valid leads acquired.
Pro tip Include prior lead-magnet acquisition costs when evaluating the full cost of reacquiring or retargeting existing leads.
Watch out Do not compare paid and organic conversion rates without acknowledging their different acquisition histories.
- 3
Calculate earnings per lead
Divide cohort revenue by the number of leads in that cohort to reveal the economic return generated per lead.
Pro tip Run both immediate-launch and longer cohort views.
Watch out Using only first-month revenue can undervalue a membership customer.
- 4
Add lifetime customer value
Estimate the total average revenue generated by a customer over the relationship and apply it to acquired customers.
Pro tip Use observed retention and revenue data rather than an aspirational estimate.
Watch out An inflated lifetime-value assumption can justify otherwise unprofitable spending.
- 5
Measure conversion delay
Determine how long leads generally remain on the list before purchasing and monitor later conversions from each cohort.
Pro tip Align reporting windows with the actual purchase cycle.
Watch out Short attribution windows may make delayed buyers appear unrelated to the original campaign.
- 6
Choose acquisition timing
Compare the economics of buying leads during the launch with acquiring them earlier at lower cost and nurturing them before retargeting.
Pro tip Build the list when costs are favorable and reserve expensive periods for warm-audience conversion campaigns.
Watch out External events can raise advertising costs and invalidate assumptions from a previous launch.
In the wild
The team reported approximately 17,500 paid leads, about 674 directly tracked sales, a roughly 3.9% conversion rate, a $3.60 launch cost per lead, and an estimated $500 customer lifetime value. Rick advised separating cold and warm leads, then calculating earnings per lead rather than judging the campaign only against the higher organic conversion rate.
→ The team gained a fuller basis for deciding whether paid leads were economically worthwhile despite lower immediate conversion.
The team considered acquiring sub-$1.50 lead-magnet subscribers during the summer, nurturing them for several months, and using retargeting rather than cold acquisition during a costly election-season launch.
→ Acquisition and conversion spending are moved to the periods where each is expected to work most efficiently.
Common mistakes
Comparing conversion rates alone
Organic audiences are often warmer than paid audiences, so conversion-rate differences do not by themselves establish which source is more profitable.
Ignoring delayed buyers
Evaluating only the current launch can classify leads as wasted even when they purchase after the normal nurture period.
Using blended paid traffic
Combining cold acquisition and warm retargeting prevents the team from seeing the economics of either cohort clearly.
Is it for you?
Best for
It is best for businesses deciding how much to spend on lead generation before or during a launch.
Not ideal for
It is not ideal when customer value, acquisition source, or cohort conversion data cannot be measured with reasonable confidence.

“What does that mean for revenue?”
“And so that way, that way we can start to calculate what our earnings per lead is and say, Oh, I paid three 60, but…”
“How many of those of those 17,500 were cold, meaning just coming into Jasmine's world for the first time registering and then looking at that…”
