Cart abandonment is often driven by unexpected fees, a lengthy checkout process, or limited payment methods. To improve this, provide a clear breakdown of costs early in the process, as surprise fees deter buyers. A streamlined checkout with fewer steps and no mandatory account creation can improve completion rates. Additionally, offering multiple payment options, like credit cards, PayPal, or other popular choices, makes it easier for customers to pay. Consider adding exit-intent pop-ups or limited-time discounts as incentives for customers to complete their purchases, lowering your cart abandonment rate.
