A garden nursery client had healthy traffic, full carts and thin sales. We changed nothing about the products and everything about the last three screens.
Cart abandonment is rarely about price. It is about surprise and effort: costs that appear late, forms that ask too much, and doubt that shows up at exactly the wrong moment. We attacked those three things one release at a time.
Each change shipped alone with a fortnight of data before the next. That discipline matters: two of our other ideas actually hurt conversion in testing and were rolled back. The five above earned their place.
Season over season, revenue finished 31% up on flat traffic. Nothing in the list is exotic. Checkout optimization is mostly the patient removal of reasons to hesitate.
