how to win amazon buy box 1

80% of Amazon sales go through the Buy Box. That means only a small portion is left for sellers who don’t win it. If you’ve been wondering why your products aren’t selling as much as expected, the Buy Box might be the reason. 

This comprehensive guide on how to win Amazon Buy Box will show you from the definitions, key factors, to 7 experts’ tips to win the  Buy Box on Amazon. 

Key Takeaways:

✅ Winning the Buy Box can lead to a substantial increase in sales and access to exclusive advertising opportunities such as Amazon’s Pay-Per-Click (PPC) ads.

✅ If multiple sellers have similar pricing and performance, Amazon may rotate the Buy Box to give each a share of sales.

✅ Amazon’s sophisticated algorithm considers multiple factors when determining the Buy Box winner.

✅ Key factors for Buy Box’s success include competitive pricing, strong seller performance metrics, sufficient inventory, and efficient fulfillment methods like FBA.

✅ Becoming a Prime seller through FBA or SFP meaningfully enhances your chances of winning the Amazon Buy Box because of the fast and reliable shipping.


What is the Amazon Buy Box? 

Amazon Buy Box is the white box on the right side of a product page, featuring the notable “Add to Cart” and “Buy Now” buttons. 

It is where the majority of Amazon sales occur because shoppers can quickly purchase items without selecting a seller, as the Buy Box assigns the sale to one specific seller among multiple sellers offering the same product.

The Buy Box shows important information like the product price, delivery details, and sometimes the seller’s name. Also, only one seller “wins” the Buy Box at a time, determined by Amazon’s algorithm based on various factors.

Benefits of winning the Amazon Buy Box 

In short, the Buy Box is the gateway to significantly increased sales and exclusive advertising opportunities. Let’s delve into why securing the Buy Box should be a top priority for any Amazon seller. 

Increase your sales chances 

Amazon Buy Box isn’t just a convenient feature; it’s the primary path to purchase for most customers. Research indicates that a staggering 80% of Amazon sales go through the Buy Box, and this percentage is even higher for mobile purchases. This means if you’re not winning the Buy Box, your product visibility is severely limited, and your sales potential takes a massive hit. 

When your product appears in the Buy Box, it automatically becomes the default choice for customers. They can add it to their cart with a single click. 

Create Amazon PPC ads 

Knowing how to win Amazon Buy Box not only opens the floodgates to organic sales but also grants you access to Amazon’s Pay-Per-Click (PPC) advertising platform. This great tool allows you to create targeted ads that appear prominently in search results as well as on product detail pages. However, there’s a catch – only sellers who win the Buy Box are eligible to run these PPC campaigns.

This combination of organic sales through the Buy Box and targeted advertising through PPC campaigns can create a snowball effect, propelling your products to the top of the Amazon rankings.

How Does the Buy Box Work?

how does the Amazon buy box work

The Amazon Buy Box works through a sophisticated algorithm that determines which seller’s offer is featured in the Buy Box on a product detail page. To understand how to win the Buy Box on Amazon, you first need to know how this algorithm works.

This algorithm evaluates several key factors to choose the best seller to give customers the optimal buying experience. Some key factors that influence the Buy Box algorithm include fulfillment methods, landed price, shipping time, stock availability, and more. 

The Buy Box isn’t static. Amazon’s algorithm continuously reevaluates eligible sellers, so the winner can change every hour or day. 

If multiple sellers have similar pricing and performance, Amazon may rotate the Buy Box to give each a share of sales. The rotation frequency depends on the product’s popularity and the number of eligible sellers.


8 Key Factors for Winning Amazon Buy Box 

key factors for winning buy box

Learn how to win an Amazon buy box, let’s discover the essential eligibility factors. Achieving excellence in these factors and providing an exceptional customer experience is the most effective way to gain a share of the Buy Box.

1. Fulfillment method

The fulfillment method is the most important factor when it comes to winning the Buy Box. FBA receives a perfect score from Amazon for various variables, including shipping method, on-time delivery, and inventory depth, making it challenging for merchants to outperform FBA sellers. 

Sellers enrolled in Seller-Fulfilled Prime have a higher chance of winning the Buy Box compared to FBA sellers. To participate in the Seller-Fulfilled Prime program, sellers must demonstrate strong performance metrics and a proven track record of meeting customer expectations. 

2. Landed price

The landed price is the total cost to the customer, including shipping. 

A common misconception is that having the lowest price guarantees winning the Buy Box. While a lower price does increase the likelihood of winning a share of the Buy Box, it is just one of the criteria, albeit an important one.

3. Shipping time

The time taken by a seller to ship an item, known as the shipping time, has a significant impact on winning the Amazon Buy Box, especially for items like birthday cards and perishable goods. 

Shipping time is categorized into the following brackets, considering only working days: 0-2 days, 3-7 days, 8-13 days, 14 or more days. The shipping time can be viewed on the product detail page, indicating the estimated delivery date.

4. Stock availability

Typically, if a seller doesn’t have the item in stock, they can’t win the Buy Box, and it will rotate to another seller. Therefore, it is crucial for sellers to maintain sufficient stock levels for their best-selling products. 

An exception to this rule is when a product can be listed as “back-ordered,” accompanied by a note on the product page. Backordered items can still be featured in the Buy Box, but products that are immediately available are preferred.

5. Order defect rate

The Order Defect Rate (ODR) is a crucial performance metric that directly impacts how to win the Buy Box Amazon. 

It consists of three metrics: negative feedback rating, A-Z guarantee claim rate, and service chargeback rate. Amazon calculates these metrics to identify the number of defective orders. According to Amazon’s guidelines, the ODR should be below 1%, and sellers above this threshold may face penalties.

6. Valid tracking rate

This is a new performance metric introduced by Amazon, representing the percentage of total packages shipping with valid tracking. To maintain Buy Box eligibility, sellers should provide valid tracking numbers for 95% of packages shipped. Falling below this threshold could affect their chances of winning the Buy Box and selling within a specific category.

7. Late shipment rate

The Late Shipment Rate indicates the number of orders that ship later than the expected ship date. Sellers can set their handling time in Seller Central, and those who don’t will be assigned the default shipping time of 1-2 business days. A Late Shipment Rate below 4% improves the chances of securing a share of the Buy Box. This metric is available for the last seven and 30 days in Seller Central.

8. Response time 

The last factor in how to win Amazon Buy Box is response time. Amazon gives priority to sellers who deliver fast and reliable customer service.

Sellers should respond to customer inquiries within 24 hours, with Amazon expecting 90% of questions answered on time. For competitive Buy Box eligibility, a response time of under 12 hours is recommended. 


How to Check Buy Box Eligibility on Amazon  

To determine Buy Box eligibility, sellers can refer to Seller Central inventory reports. The default view does not display the “Buy Box Eligible” column, but you can enable it by following these steps: 

  1. Go to the Inventory tab, click Manage Inventory.

How to Win Amazon Buy Box: 7 Tips to Success

We’ll break down how to win the Amazon Buy Box and help your business increase sales.

1. Offer fast, free shipping with tight delivery windows 

Amazon’s algorithm strongly favors faster delivery windows. Next-day delivery or within 24-48 hours is often necessary, especially for popular products. Even small improvements in handling time, such as reducing from 2 days to 1 day, can give sellers an edge in the Buy Box competition. 

To provide fast delivery, sellers can choose fulfillment options such as Fulfillment by Amazon (FBA), Seller-Fulfilled Prime, or even a hybrid approach. These methods help ensure reliable shipping speeds while keeping products Prime-eligible. 

Additionally, offering free shipping improves Buy Box eligibility, as it aligns with customer preferences and Amazon’s goal of providing a low total cost for buyers. Sellers who combine fast shipping with free shipping tend to win the Buy Box more often.

3. Keep excellent seller metrics

Several key metrics influence your ability how to win Amazon Buy Box. These include order defect rate, late shipment rate, pre-fulfillment cancel rate, customer service responsiveness, and overall customer satisfaction. 

Maintaining excellent performance in these areas is essential for increasing your chances of winning the Buy Box: 

  • Order defect rate (ODR): Should be below 1%. This metric includes negative feedback, A-to-Z claims, and chargebacks. 
  • Cancellation rate: This is the percentage of orders canceled by the seller before shipment. A low cancellation rate indicates reliability and good inventory management.
  • Late shipment rate: Should be less than 4% to ensure timely delivery and high customer satisfaction.
  • Customer response time: Respond to buyer inquiries ideally within 24 hours to prevent dissatisfaction and negative feedback.
  • Valid tracking rate & on-time delivery: Aim for over 90% valid tracking and more than 97% on-time deliveries.

4. List as a Prime seller

Being a Prime seller is another effective way on how to win Buy Box on Amazon. Amazon Prime members prefer purchasing from sellers who offer Prime shipping because it guarantees fast and reliable delivery. As a result, Amazon gives preference to Prime sellers when awarding the Buy Box.

Specifically, Seller-Fulfilled Prime (SFP) allows sellers to fulfill orders directly while still qualifying for the Prime badge, combining the benefits of Prime-level service without using Fulfillment by Amazon (FBA).

  • Respond promptly to customer inquiries: Address customer questions and concerns promptly and professionally. 
  • Proactive issue resolution: Address negative feedback and complaints quickly. Offer refunds, replacements, or other remedies promptly.
