The checkout page is one of the most important pages on any retailer’s eCommerce site. It’s the final hoop visitors have to go through in order to make a purchase. You can make this an easy or difficult process depending on your user experience. For instance, if your checkout process is time-consuming because your forms are too long, this can create enough friction that can push visitors away.
On the other hand, if your checkout process is seamless and fast, this can increase the chances of closing the sale and at the same time motivate the customer to come back for a repeated purchase. Think about Amazon’s checkout process. It’s so fast that it encourages consumers to keep coming back to the platform to order more products. If their user experience was not up to par, they would get less repeat orders, even while offering better prices than other websites. Remember that time is money, so anything that you can do to speed up your checkout process will be greatly appreciated by your customers.
