What Causes Cart Abandonment?
The most common causes: unexpected shipping costs revealed at checkout, forced account creation before purchase, a checkout process that is too long or complex, and lack of trust signals at the payment step. Together, these account for the majority of abandonment on most stores. The fix is not one change — it is diagnosing which cause is responsible for the most drop-off on your specific store, then addressing that first.
What Is Cart Optimization?
Cart optimization is the process of reducing drop-off between the cart page and checkout. Common changes: adding a free shipping progress bar, showing a clear order summary with product images, placing the checkout button above the fold on mobile, and removing navigation links that pull customers away before they buy. Cart page optimization typically improves the add-to-cart-to-checkout rate by 5 to 15%, without requiring changes to the checkout itself.
