The Ideal Checkout Flow
3-4 steps maximum: Cart review → Shipping info → Payment → Confirmation. Each additional step increases abandonment by ~10%. Use progress indicators so shoppers know where they are. Enable address auto-complete with Google Places API. Auto-detect credit card type from the first digits. Make form fields large and mobile-friendly.
Trust Signals That Convert
Place security badges (SSL, McAfee, Norton) near the payment button. Show payment processor logos (Visa, Mastercard, PayPal). Include customer service contact info visibly. For EU customers, display GDPR compliance and EU data center badges. A/B tests consistently show trust badges increase conversion by 5-15%.
Mobile Checkout Optimization
Mobile has an 85.65% abandonment rate — the highest of any device. Make buttons thumb-sized (minimum 44px). Use mobile-specific payment methods (Apple Pay, Google Pay) that eliminate typing. Auto-format phone numbers and credit cards. Test on actual devices, not just browser emulators. Consider a single-page checkout for mobile.
Reducing Form Friction
Only ask for essential information. You don't need a phone number for digital products. Use smart defaults (default country based on IP, default shipping = billing address). Enable paste for all fields. Show clear error messages inline, not at the top of the page. Mark optional fields as optional, not required fields as required.
