    What is an Auction Feature on eBay :

    Auction Listings:

    eBay’s auction feature allows sellers to list items for sale at auction. This means the seller indicates the start and duration of the auction rather than setting a fixed price.

    Bidding process:

    Buyers can bid on goods during the auction period. Bidding usually starts with the seller’s initial bid, and the user can gradually increase the bid.

    Dynamic Pricing:

    An important feature of eBay auctions is dynamic pricing. As users bid, the price of the product gradually increases until the auction ends. At the end of the competition, the person with the highest bid will win the product.

    Reserve Price:

    Sellers can set a reserve price, which is the minimum amount they are willing to accept for the product. If the price is not maintained until the end of the auction, the item will not be sold.

    Auction Duration:

    eBay has various auction durations, usually from a few days to a week. Sellers choose the time that suits their interests.

    Proxy bidding:

    eBay uses proxy bidding, where users can set the highest price they are willing to pay for an item. The system automatically increases their bids to maintain their winning position up to the maximum bid.

    Popcorn bidding:

    Popcorn Bidding, also known as Dynamic Bidding, is a way of giving the bidders who were outbid an opportunity to rebid. Enable this option, and enter the time within which you want to extend the auction deadline. Lastly, enter the number of times this whole popcorn bidding scenario can reoccur.

    Sniping:

    Sniping is a strategy where players place their highest target near the end of the match, preventing others from attacking them at the same time.

    Transparency:

    eBay’s auction system is transparent and users can see the current high bid and the number of bids placed on an item. This transparency helps build trust among users.

    eBay’s auction feature adds to its unique business platform by providing users with a powerful and engaging way to buy and sell a variety of items.

    Proxy Bidding

    You can also enable Proxy Bidding, Proxy Bidding is a concept in which the system automatically bids on your behalf up to the maximum bid amount that you have chosen. This is simple to make the online auction process much easier and less time-consuming. The Proxy Bid is the Maximum Bid and not the Current Bid.

    How does Proxy Bidding actually work?

    Let’s understand this with a scenario: Suppose an auction starts with $10 as the starting bid. Now, bidder A places a proxy bid of $20.So, now the system will automatically start bidding from $10 up to $20 on behalf of bidder A. Now, if bidder B comes to place a bid, he will see the current bid of $10. Suppose, Bidder B places a bid of $15. Then, he will be immediately outbid by bidder A with a new minimum bid of $16.Thus to outbid bidder A, some other bidder has to place a bid of $20.01 or more.
    Now, if bidder B places a bid of $20 then it will be equivalent to bidder A’s maximum bid. But still, bidder A will be the highest bidder and the new minimum bid will become $21.So, this is how the flow of proxy/automatic bidding goes.

    You can also do Seller Restriction, Restricting seller to make changes, This is only for Multivendor (MVM) side.
