The sites are ranked in terms of unique viewers, based on data gathered by DoubleClick Ad Planner. Google explains how this advertising service determines a website’s weight: “DoubleClick Ad Planner combines information from a variety of sources including anonymized, aggregated Google Toolbar data from users who have opted in to enhanced features, publisher opt-in anonymous Google Analytics data, opt-in external consumer panel data, and other third-party market research.”
Google has excluded some sites from the list–notably, several Google properties as well as R-rated sites.
