❓ What is a Second price auction : definition, examples of use.

What is Second price auction?

The second price auction is a bidding method where the highest bidder wins but pays the price of the second-highest bid instead. This approach encourages honest bidding since bidders are incentivized to bid their true valuation, knowing they will not pay their bid amount unless they are outbid. This mechanism is increasingly relevant in click fraud protection, where advertisers aim to optimize their costs while ensuring they reach their target audience effectively.

How Second Price Auction Works

In a second price auction, each bidder submits a sealed bid without knowing the other participants’ amounts. Once the bids are collected, the highest bidder is determined, but the price paid is equal to the second-highest bid. This encourages participants to reveal their true valuations as they are protected from the risk of overbidding, fostering a competitive yet fair environment.
