Current state
h1: Wildly Comfortable. Super Natural.; cta: SHOP MEN / SHOP WOMEN; notes: No subheadline present; the hero is feature-led and doesn't mention the visitor's frustration (e.g., uncomfortable shoes, desire for sustainable options).
Change
h1: Shoes That Feel Like Nothing. Made From Nature.; cta: Shop Men / Shop Women; notes: Add a subheadline: 'Find your perfect fit for all-day comfort, made from sustainable materials.' This directly addresses comfort and sustainability, the brand's key differentiators.

Rollback
Feature-flag the change; revert the flag if the primary metric
drops for 3 consecutive days.
annual visits × baseline conversion × relative lift × order value
= 2,160,000 annual visits x 2.10% conversion x 2.0-8.0% relative lift x $78 order value
The 2.0–8.0% relative-lift band is an assumption bounded by severity (Urgent), not a prediction.
Why the range is conservative: Across 127,000 experiments, 12% produced a statistically significant improvement on the primary metric; a healthy programme win rate is 10-30%. Winning tests also overstate their true effect, so treat this as the prize if the change works — never expected revenue.

Sample size math
Two-proportion z-test, the standard pre-test sample-size calculation:
n = [z₀.₀₂₅·√(2·p̄·(1−p̄)) + z₀.₂₀·√(p₁(1−p₁)+p₂(1−p₂))]² / (p₁−p₂)²
Baseline conversion
2.1%
Significance / power

Sample per variant, 8.0% lift

Sample per variant, 2.0% lift

Halving the minimum detectable effect roughly quadruples the sample required, which is why the conservative figure is so much larger.
What PXL is
PXL is CXL's prioritisation framework: binary questions instead of subjective 1–10 guesses, weighted toward evidence.
Findings discovered by inspection score zero on all four evidence questions — that is the honest signal, not a defect. Findings verified by direct measurement earn the extension point and, where real-user field data is involved, the analytics point.
