Illustrative Case Study
Based on realistic usage patterns and typical results reported by users — not a verified customer story. Numbers are illustrative.
The Problem
An e-commerce brand doing $2.2M/yr had a 1.9% checkout conversion rate. The marketing manager suspected the checkout flow was leaking revenue but had no way to test changes without developer time (2-week sprint queue).
The Solution
Signed up for VWO ($199/mo). Used the visual editor to test a green 'Complete Purchase' button against the existing gray one — no developer involved. Test ran for 21 days with 8,200 visitors.
The Result
Green button variant won with 94% statistical confidence. Conversion rate went from 1.9% to 2.4%. At $2.2M annual revenue, that 0.5% lift added $64,000 in incremental revenue over the next 12 months.
💡 ROI Estimate: Tool costs $199/mo ($2,388/yr). One test added $64,000/yr in revenue. ROI: 27x.
