Test Period: June 1, 2026 – August 9, 2026 (70 Days / 10 Weeks) • Sample Size: 1.83M Visitors
Comparing aggregate metrics across all 70 days. Statistical tests (Two-proportions Z-test) are measured against Control (Variant A).
| Variant | Visitors | Clicks (CTR) | Add to Cart (Rate) | Purchases (Orders) | Cart-to-Order % | Overall Conv. Rate | Lift vs Control | Stat Sig (95% CI) |

Comparing end-to-end purchase conversion efficiency with 95% confidence intervals.
Demonstrating how high click rates (Variant C) failed to translate into revenue compared to Variant F.
Weekly purchase conversion rates confirm Variant F maintained consistent superiority throughout the experiment.
Progression down each stage of the funnel for key variants (Control A, High-CTR C, and Winner F).
Variant F succeeded because it qualified user intent early. It improved CTR moderately (+8.8% vs Control), but more importantly maintained high cart qualification (16.2% of clickers added to cart) and high checkout completion (36.1% of carts converted to orders). This proves the page redesign set accurate buyer expectations.
Variant C had the highest click-through rate by far (49.4% vs Control's 35.5%), but suffered severe drop-off later in the funnel. Its Cart → Purchase rate plummeted to 24.3% (vs 36.8% for Control). This pattern indicates the call-to-action or copy was overly broad, provocative, or misleading, drawing low-intent tire-kickers.
Variant H was the worst performing redesign across the board (-15.4% lift vs Control, 1.52% overall CR). Its cart addition rate fell to 14.2% and checkout completion dropped to 31.5%. The design changes in Variant H created friction and discouraged checkout.
Tracking weekly cohort trends over the full 70-day test reveals no novelty fatigue. Variant F's conversion rate stayed in the 2.15%–2.30% corridor across all 10 weeks, demonstrating that the lift is durable and permanent.
Allocate 100% of production landing page traffic to Version F. Deprecate versions B, D, E, G, and H.
Analyze why F's layout reduced bounce and improved checkout willingness. Document layout and copy guidelines as new brand standards.
Explore if headline/hero elements from C can be refined and infused into F without diluting purchase intent, aiming for an incremental 5–10% lift.
