Framework: Quantitative Funnel Breakdown -> Mobile Usability Heuristics -> High-Friction Reductions -> Rapid A/B Testing.
1. Quantitative Funnel Analysis:
- Identify the exact drop-off step: Is it page load speed, form field interactions, or payment method entry?
2. Mobile Usability Audit:
- Form Fatigue: Mobile keyboards are tedious. Audit the form: can we eliminate 50% of the inputs? Auto-detect city/state from ZIP code? Enable browser autofill attributes (autocomplete='shipping address-line1')?
- Keyboard Ergonomics: Ensure numeric keyboards trigger automatically on phone/card fields (inputmode='numeric').
- Page Performance: Check mobile bundle size and First Contentful Paint on 4G cellular connections.
3. Modern Mobile Payments:
- Introduce native 1-click payment sheets (Apple Pay, Google Pay) to completely bypass manual credit card and address entry.
4. Success Metrics:
- Mobile conversion rate, checkout completion time, mobile form error rate.
