Google makes most of its money from selling advertising opportunities on the search pages so many of us use.Advertisers bid to have ads for their products or services displayed on relevant search query result pages. A combination of the amount bid and the quality of a potential ad influences if an advertisement will feature at the top of the page, where more users are likely to see it. In order to encourage efficient bidding practices, Google uses a Vickrey auction system. Bidders don't know their rivals' bids. When all bids are in, the highest bidder wins but actually pays the price of the second highest bidder.
