SearchEngineLowdown: Google Sues AdSense Fraudsters

Google cracked down on alleged click fraudsters today, suing Texas-based Auction Experts for allegedly clicking on their own AdSense links in order to generate more per-click income. Google's complaint said that the firm "flagrantly abused the AdSense Online service by artificially and/or fraudulently generating ad clicks." Click fraud has become an increasing problem for pay-per-click advertisers, especially among categories that command very high click prices.
