Checkout Optimization Tips
- Offer guest checkout: 34% of abandoned carts are due to forced account creation
- Show multiple payment options: Card + PayPal + Apple Pay increases conversion 12%
- Display trust badges: SSL seal, money-back guarantee, security logos
- Minimize form fields: Name, card number, expiry, CVC. Thats it.
- Enable one-click checkout: Stripe Link, Shop Pay, or Amazon Pay
The best gateway depends on your platform. Shopify stores should always use Shopify Payments. Everyone else should default to Stripe.
