Short answer

The clearing price is the final amount paid for an ad impression once an auction concludes, after floors, fees, and any bid shading are applied. In first-price auctions it equals the winning bid; in second-price auctions it is set by the runner-up bid. Tracking clearing prices helps buyers bid efficiently and publishers set floors.
