If you sell on Amazon, you’ve likely heard about the Buy Box, the section on a product page where customers can click "Add to Basket" or "Buy Now." Winning the Buy Box is crucial for maximising sales, as most purchases are made through this feature.

But what exactly is the Amazon Buy Box, and how can you improve your chances of winning it? Let’s break it down.

What Is the Amazon Buy Box?

The Buy Box is the white box on the right of an Amazon product page where customers add items to their baskets. If multiple sellers list the same product, Amazon decides which seller is featured in the Buy Box at any given time.

Since most customers simply click the Buy Box without checking other sellers, winning it means more sales. If you don’t have the Buy Box, customers will need to click "Other Sellers on Amazon", significantly reducing your chances of making a sale. In reality,  82% of sales on Amazon are completed through the Buy Box. This percentage rises for mobile device sales, and many experts estimate that the total could be as high as 90%.

Who Is Eligible to Win the Buy Box?

Not all sellers are eligible for the Buy Box. To qualify, you must:

• Have a Professional Selling Plan (individual accounts aren’t eligible).
• Maintain high seller performance metrics (including order defect rate, late shipment rate, and response time).
• Offer competitive pricing (including both product price and shipping).
• Have sufficient inventory availability to fulfil orders.

How Does Amazon Decide Who Wins the Buy Box?

Amazon’s Buy Box algorithm considers several factors when selecting the winning seller. Here are the key ranking factors:

1. Fulfilment Method (FBA vs FBM)

• Fulfilment by Amazon (FBA) sellers often have an advantage, as Amazon prefers Prime-eligible products with fast shipping.
• Seller-Fulfilled Prime (SFP) can improve your chances, as it meets Amazon’s fast delivery standards.
• Fulfilled by Merchant (FBM) sellers must compete by offering low prices and fast, reliable shipping.

2. Price Competitiveness

Amazon considers the total price (product price + shipping). To stay competitive:

• Monitor pricing regularly and adjust as needed.
• Use repricing tools to automate price adjustments.
• Offer free shipping if possible, as it can impact the Buy Box win rate.

3. Seller Performance Metrics

Amazon rewards sellers with strong performance records. Key metrics include:

• Order Defect Rate (ODR) – Keep negative feedback, chargebacks, and A-to-Z claims below 1%.
• Late Shipment Rate – Ensure orders are shipped on time, with a target below 4%.
• Cancellation Rate – Avoid cancelling customer orders due to stock issues.
• Customer Response Time – Respond to customer messages within 24 hours.

4. Inventory Availability

If your stock levels are low, Amazon may rotate the Buy Box to another seller with better availability. To avoid this:

• Keep inventory well-stocked, especially for high-demand products.
• Use Amazon’s Restock Report to predict demand and prevent stockouts.

5. Customer Experience & Reviews

Positive customer feedback boosts Buy Box chances. To maintain high ratings:

• Provide excellent customer service and respond to queries promptly.
• Follow up on orders to encourage positive reviews.
• Resolve customer complaints quickly to avoid negative feedback.

How to Improve Your Chances of Winning the Buy Box

If you’re struggling to secure the Buy Box, try these strategies:

• Use FBA or Seller-Fulfilled Prime – If you’re not using FBA, switching to Amazon’s fulfilment service can improve your chances.
• Keep Prices Competitive – Regularly monitor competitor pricing and adjust accordingly.
• Optimise Your Shipping Speed – Offer same-day or two-day delivery where possible.
• Maintain Excellent Seller Metrics – Prioritise customer service, avoid late shipments, and minimise negative reviews.
• Ensure Consistent Stock Levels – Keep inventory updated to avoid losing the Buy Box due to stock shortages.

Can You Still Make Sales Without the Buy Box?

Yes, but it’s much harder. If you don’t win the Buy Box, customers must click "Other Sellers on Amazon", where competition is fierce. To improve your chances of still making sales:

• Offer a lower price than the current Buy Box winner.
• Use Amazon Advertising (PPC) to boost visibility.
• Work on improving your seller metrics over time.

Winning the Amazon Buy Box can significantly increase your sales, but it requires a strategic approach. By optimising pricing, fulfilment, inventory, and customer service, you can improve your chances of securing that crucial spot.

Stay consistent, monitor your performance, and make data-driven decisions to keep your business competitive on Amazon.
