A sample answer to question 1

How does the Amazon Buy Box work, and what would you do to win and keep it?

The Buy Box is the 'Add to basket' button on a product page, and it's awarded to one eligible seller at a time through Amazon's algorithm. The main factors are competitive landed price including delivery, fulfilment method with FBA or Prime-eligible offers favoured, seller performance such as order defect rate, late dispatch and cancellation rate, and stock availability. To win it, I'd start with the fundamentals: use FBA or Seller Fulfilled Prime, keep inventory in stock, and keep the Account Health metrics comfortably within target. On price, I'd use Amazon's automated repricing rules with a floor based on margin so we compete without racing to the bottom, and I'd check Buy Box percentage by ASIN in Business Reports to find where we lose it. If another seller keeps winning, I'd investigate whether it's an authorised reseller, a hijacker or Amazon itself, since each needs a different response. I'd also watch that promotions and coupons don't push us below the floor.

Common mistake to avoid: Racing to the lowest price; Ignoring seller performance metrics
