Search Ads with Google

How it works

  • Every time for a search result, it will do an auction to price different ad locations. The advertiser would need to pay only if the user clicks the ad.
    • When the user clicks, the advertiser only needs to pay second-highest price.
    • This can guarantee that they bid their true value.
