Google's click-fraud tracking site.

Google has announced it's new Web site to serve as the single source for all click-fraud and ad traffic-quality-related information. Google developed the new Ad Traffic Quality Resource Center primarily to give its advertisers a single place to find Google's information about click fraud, said Shuman Ghosemajumder, business product manager for trust and safety at Google, on Friday. In the pay-per-click format, advertisers pay every time someone clicks on their ads, which are linked to a Web page. Click fraud happens when companies click on competitors' ads to drive up their ad spending. Another common click-fraud practice is for Web publishers to click on their sites' ads to increase their commissions.
The group decided to prioritize organizing a click-fraud forum for Google advertisers that was held at the company's headquarters in May, he said. A similar event will be held later this month in Google's New York City offices, he said.
Already in place is a service called IP Filtering, which lets advertisers "blacklist" certain IP (Internet Protocol) addresses for whatever reason, such as suspicion of click fraud or simply because their clicks never lead to a sale, he said.
