BuyBox is the algorithm that decides which seller’s offer gets pre-selected and shown to customers (the “buybox winner”) for a given product (and product configuration), and at what price. Only one seller can win the Buybox at a time, and winning it significantly increases your visibility and sales potential.
Buybox algorithm takes different aspects into account to calculate the best winning offer. The algorithm calculates a ranking score based on the Seller Performance score and the price the sellers sets for the offer. The score gets calculated only for sellers which had at least 100 order items in the last 35 days. Price adjustments and competitive pricing strategies can help you win more Buyboxes
The Buybox winner changes dynamically based on real-time factors like price changes or performance updates. Even if you don't win the Buybox, your offer is still visible to customers who click "See all offers".
