How eBay Auctions Work
eBay auction is a timed bidding format where buyers place incremental bids on listed items, and the highest bidder wins when the countdown ends. The platform supports standard auctions, reserve-price auctions, and multi-item listings, with sellers setting start prices, bid increments, and duration options. eBay provides structured rules around bidding increments and auto-bid functions to keep the process transparent for both buyers and sellers eBay Bidding Policy.
