How to win the buy box

Alright, so now that you know what it takes to be buy box eligible and what Amazon looks at in order to determine who wins the buy box, but how do you actually win the buy box?

Well... there's no simple formula and no guarantee to winning the buy box, but there are things you can do to improve your chances. We've listed out 7 ways to improve your chance of winning the buy box.

1. Price and Fulfillment

Right now, these are the two biggest factors to winning the buy box. Maintaining an affordable price and having your product in stock and shipped on time, is the most important thing you can do.

2. Choose FBA

As mentioned before, FBA products have a much better chance of winning the buy box. That's because FBA items have free two day shipping and are almost always shipped on-time. If it makes financial sense for you to switch to FBA, then we highly advise that you do so.

3. Seller Account Health

If you seller account health dips in any metric, then you run the chance of losing the buy box on all of your products and you run the risk of your account being suspended. Amazon favors reliable sellers for obvious reasons. Amazon calculates your seller-fulfilled seller rating based these metrics:


Order Defect Rate (Target = < 1%)

  • Negative Feedback Rate
  • Filed A to Z Claim Rate
  • Service Chargeback Rate

  • Negative Return Feedback Rate
  • Late Response Rate
  • Invalid Rejection Rate

  • Response Times Under 24 Hours (Target = > 90%)
  • Late Responses (Target = < 10%)
  • Average Response Time

4. Improve you customer feedback score

Amazon’s Seller Feedback Score is constantly updating based on aggregate reviews from Amazon orders and constitutes an average of overall order ratings. This score has an impact on your buy box eligibility, so it's important to make sure you have a positive seller feedback score.

Pro Tip: A lot of customers will often leave product reviews on your seller feedback page. If this feedback is negative, you can contact Amazon and they will quickly remove this feedback so it won't adversely effect your overall seller feedback score.

5. Keep your product in stock

Products that run out of stock often are considered less stable by Amazon and therefore have less of a chance of winning the buy box. The more you maintain product stock, the more likely you can influence the buy box.
