Google Ad Rank is an algorithm that Google use to determine what position your Ad achieves in the Google Adwords Auction.
Ad Rank is a function of the Maximum Bid Price, Your Quality Score and your use of Ad Extensions that are available for you to use. Generally speaking, the higher your Ad Rank the less you pay.
