Seller score
Platforms & Channels
Seller score is a marketplace-assigned performance rating based on return rate, fulfilment speed, and dispute frequency, directly influencing search ranking and, indirectly, pricing power.
On platforms like Back Market and Amazon, a higher seller score gives access to better search placement, which enables sellers to price at or slightly above the market average while still winning conversions. Lower-scored sellers must discount more aggressively to compensate for reduced visibility. Because grading consistency is the primary driver of return rate and disputes, seller score is ultimately a proxy for grading quality, and investing in grading accuracy produces compounding pricing power over time.
