How to Win the Amazon Advertising Buy Box and Boost Your Sales

Hi everyone, welcome to another article on Amazon advertising. In this article, we will talk about one of the most important aspects of selling on Amazon: the Buy Box.

The Buy Box is the white box on the right side of a product detail page that allows customers to add the product to their cart or buy it with one click. It is where most of the sales on Amazon happen, and it is also where you can run your pay-per-click (PPC) ads to reach more customers.

But how do you win the Buy Box? What factors does Amazon consider when deciding which seller gets the Buy Box? And how can you optimize your advertising strategy to take advantage of the Buy Box? These are some of the questions we will answer in this article, so keep reading to learn more.

What is the Amazon Buy Box Algorithm?

The Amazon Buy Box algorithm is the formula that Amazon uses to determine which seller gets the Buy Box for a given product. The algorithm is not publicly disclosed, but it is based on several factors that measure the seller's performance, price, availability, and customer satisfaction.

The algorithm is constantly updated and changes depending on the product category, demand, competition, and other factors. Therefore, winning the Buy Box is not a one-time achievement, but a continuous process that requires constant monitoring and optimization.

Why is the Amazon Buy Box Algorithm Important?

The Amazon Buy Box algorithm is important because it affects your sales and advertising potential on Amazon. According to some estimates, 82% of sales on Amazon come through the Buy Box[^1^]. This means that if you are not in the Buy Box, you are missing out on a huge portion of customers who are ready to buy.

Moreover, only products that win the Buy Box are eligible for advertising. This means that you can only run PPC ads for your products if you have the Buy Box. PPC ads are sponsored listings that appear on relevant search results and product pages, and they can help you increase your visibility, traffic, and conversions on Amazon.

How to Be Eligible for the Amazon Buy Box?

Before you can win the Buy Box, you need to be eligible for it. Amazon has some basic requirements that you need to meet in order to qualify for the Buy Box. These include:

  • You need to be a Professional Seller. This means that you need to pay a monthly subscription fee of $39.99 and sell more than 40 items per month[^2^].
  • You need to sell new products. Amazon does not allow used or refurbished products in the Buy Box.
  • You need to have sufficient inventory. Amazon does not want to disappoint customers by showing them products that are out of stock or have long shipping times.
  • You need to have a good seller account health. This means that you need to maintain high performance metrics such as order defect rate, cancellation rate, late shipment rate, valid tracking rate, and customer feedback rating.

If you meet these requirements, you are eligible for the Buy Box. However, this does not guarantee that you will win it. You still need to compete with other eligible sellers who are offering the same product.

How to Win the Amazon Buy Box?

Winning the Buy Box is not easy, especially if you are selling in a competitive niche or category. You need to optimize your product offer and stand out from other sellers who are vying for the same spot. Here are some of the factors that can help you win the Buy Box:


Price is one of the most important factors that influence the Buy Box algorithm. Customers are always looking for the best deal, and Amazon wants to offer them the lowest price possible. Therefore, if you want to win the Buy Box, you need to price your product competitively.

However, this does not mean that you need to undercut your competitors or sell at a loss. You need to consider your costs, margins, fees, and profits when setting your price. You also need to monitor your competitors' prices and adjust yours accordingly. You can use tools like Jungle Scout's Keyword Scout[^1^] or WebFX's Profit Calculator[^2^] to help you with this task.

Fulfillment Method

Fulfillment method is another key factor that affects the Buy Box algorithm. Fulfillment refers to how you store, pack, ship, and deliver your products to your customers. There are two main fulfillment methods on Amazon: Fulfillment by Amazon (FBA) and Fulfillment by Merchant (FBM).

FBA means that you send your products to Amazon's warehouses, and Amazon takes care of the rest. FBM means that you handle the fulfillment yourself or use a third-party service provider. Both methods have their pros and cons, but FBA generally gives you an edge in winning the Buy Box.

This is because FBA offers several benefits, such as:

  • Prime eligibility. FBA products are automatically eligible for Prime, which is Amazon's premium membership program that offers free and fast shipping, among other perks. Prime customers are more likely to buy from the Buy Box, and they also spend more than non-Prime customers.
  • Customer service. FBA products are backed by Amazon's customer service, which is known for its reliability and responsiveness. Customers can contact Amazon directly for any issues or inquiries regarding their orders, and Amazon will handle the returns and refunds if needed.
  • Inventory management. FBA products are stored and managed by Amazon, which means that you don't have to worry about running out of stock or having long shipping times. Amazon will also handle the storage fees, packaging costs, and shipping charges for you.

However, FBA also has some drawbacks, such as:

  • Higher fees. FBA products are subject to higher fees than FBM products, such as referral fees, fulfillment fees, storage fees, and long-term storage fees. These fees can eat into your profits, especially if you are selling low-margin or slow-moving products.
  • Less control. FBA products are under Amazon's control, which means that you have less say over how they are handled and delivered. You also have to follow Amazon's rules and policies regarding product preparation, labeling, packaging, and shipping.
  • Inventory limits. FBA products are subject to inventory limits, which are based on your sales volume and storage space. These limits can restrict how much inventory you can send to Amazon at a time, which can affect your availability and sales potential.

FBM, on the other hand, offers more flexibility and control over your fulfillment process, but it also requires more work and responsibility on your part. You need to ensure that you have enough inventory, that you ship your orders on time, that you provide excellent customer service, and that you meet Amazon's performance standards.

Seller Rating

Seller rating is another crucial factor that influences the Buy Box algorithm. Seller rating is a measure of your reputation and trustworthiness as a seller on Amazon. It is based on several indicators, such as:

  • Order defect rate (ODR). This is the percentage of orders that have received a negative feedback, an A-to-z Guarantee claim, or a chargeback. The lower your ODR, the better.
  • Cancellation rate. This is the percentage of orders that you have canceled before shipping them. The lower your cancellation rate, the better.
  • Late shipment rate. This is the percentage of orders that you have shipped after the expected ship date. The lower your late shipment rate, the better.
  • Valid tracking rate. This is the percentage of orders that you have provided valid tracking information for. The higher your valid tracking rate, the better.
  • Customer feedback rating. This is the average rating that customers have given you based on their satisfaction with your products and service. The higher your customer feedback rating, the better.

All these indicators affect your seller account health, which is a dashboard that shows your performance metrics and status on Amazon. You can access your seller account health by logging into Seller Central and clicking on Performance > Account Health.

You need to maintain a good seller account health in order to win the Buy Box. Amazon expects you to meet or exceed its performance targets for each indicator. For example, your ODR should be less than 1%, your cancellation rate should be less than 2.5%, your late shipment rate should be less than 4%, your valid tracking rate should be more than 95%, and your customer feedback rating should be more than 4 stars.
