Google has launched a new Ad Traffic Quality Resource Center to educate AdWords advertisers about the dangers of click fraud and Google's efforts to prevent it. It provides information on click fraud and invalid clicks, links to technical articles and Google policies, and links to contact Google reps.
Yahoo launched its Traffic Quality Center last week, with similar resources, but a much more finished look.
Much of the content for both sites existed before in different parts of the companies' sites, but these resource centers bring the information together in a single point. Creating the center was a condition of the click fraud lawsuit settlement made by Yahoo last year, but not for Google.
