Why it works
The case study earns its headline number by tying the 24% lift to a specific test with 119,000 visitors over 18 days, which gives the result credibility. The three-variation breakdown is useful because it shows which message won and why the others did not, giving readers a replicable hypothesis about offer-volume copy outperforming social proof and urgency. The mechanism is clear enough to copy: reduce steps in a form, surface a sticky banner, and test benefit-led copy against alternatives.
Steal this
Show all three variations with their specific copy and explain which lost, not just which won. The losing variations make the winning insight more convincing.
