SEARCH-TO-BID CONVERSION
Type-aware facets turn a 3.4M-item scroll into a shortlist. The proof standard: the lift concentrates in sessions that used a Set, Year, or Rarity facet, with facet usage rate as the week-one leading indicator.
SUBMISSION VOLUME
Sellers follow realized prices. Visible comps and honest deal context raise buyer conviction and sell-through, and stronger clearing prices pull the next submission. Demand conversion is the seller pitch.
BADGE INTEGRITY
Deal badges suppress when Alt Value confidence is Low, even when the discount qualifies. A badge on a shaky estimate teaches buyers to ignore every badge. Guardrail metric: badge CTR against matched unbadged tiles.
