Average Buybox Share (Avg Buybox Share) is the average share of the Buybox over the selected date range.

Seller Snap calculates the buybox share based on price change notifications provided by Amazon's Seller Central.

Amazon determines the buybox share based on the number of impressions and other data, whereas Seller Snap calculates it using Amazon's price change notifications. Because our estimates rely on these notifications, there may be instances where the calculation appears skewed, such as when no other competitors are on the ASIN or when multiple sellers share the same price and there is no change in prices at all.
