Cart abandonment - averaging 70%+ globally - is reduced through: simplifying checkout to the minimum number of steps, offering guest checkout without forced account creation, displaying trust signals (payment logos, SSL badge, return policy) adjacent to the order button, enabling UPI and EMI options prominently for Indian customers, sending automated abandoned cart email sequences triggered within one hour of abandonment, and running retargeting ads on Meta showing the specific abandoned product. The checkout experience itself is a UI/UX design problem - every extra click, confusing label, or slow-loading step in the checkout flow loses a percentage of customers permanently.
