Google has reached a settlement of its infamous "click-fraud" case, in which a class action was brought against the company on the grounds that as many as 20% of the clicks on the "pay-per-click" ads that Google runs for its customers are fraudulent. For example, an advertiser's competitor can click repetitively on a competitor's ad, knowing that each click is costing the competitor money. Such ads make up a majority of Google's revenues. As a result of the settlement, Google will reimburse certain of its its customers at a cost estimated to be as much as 90 million.
