To win the Buy Box, first make sure that both you and your listed items are eligible.
Becoming eligible to win the Buy Box doesn't guarantee that you will win it; that said, there are a few things you can do to increase your chances.
There are a few of ways to check and make sure you're pricing your items competitively.
Sellers who offer faster shipping options are more likely to win the Buy Box. You can look up your available options in Shipping Settings.
We measure customer service in several different ways, and you can check your Account Health to see how you're doing. While certain metrics such as Order Defect Rate, Cancellation Rate, and Late Dispatch Rate may weigh more heavily when considering Buy Box status, we consider all the available metrics.
Staying tuned in to all aspects of your account health is a great way to not only make sure you're working toward winning the Buy Box, but also earning customer respect and trust.
You can't win the Buy Box if you're out of stock. Keep your inventory updated and plan accordingly for things that sell quickly.
The Amazon Selling Coach can display low and out-of-stock inventory alerts, letting you know, in real time, when it's time to restock.
Listings that do not win the Buy Box are eligible for placement in the More Buying Choices box (but please note that Amazon doesn't guarantee placement in either of these locations).
