DoubleClick Ad Planner is our free, online measurement product that helps advertisers and agencies to create media plans, by providing reliable traffic and audience information for websites on which they may wish to advertise. It measures millions of sites in over 40 countries and is used by thousands of advertisers and agencies to build media plans. In recent months, we've been investing significantly in new features for DoubleClick Ad Planner. (Better site data in DoubleClick Ad Planner, Ad Planner updates provide more data, more ways)
To further our commitment to provide reliable data in DoubleClick Ad Planner, we have submitted it for accreditation by the Media Rating Council (MRC). The MRC is an advertising industry group that works to accredit audience measurement services that are valid, reliable, and effective. MRC accreditation is voluntary and some third-party measurement products have submitted for accreditation, as we have; some have not. Once complete, the MRC accreditation will provide independent confirmation that Ad Planner's methodologies, and the processes supporting this technology, adhere to industry standards.
As part of the MRC audit, we're sharing more details about our data sources and methodology. For our traffic measurement, Ad Planner uses a hybrid measurement methodology that combines direct-measured site traffic, through Google Analytics data that publishers have chosen to opt in to provide us, and sample aggregated data from Google products and services. We currently have over 10,000 sites that are contributing direct measured opt-in data to Ad Planner. Our sample data comes from a variety of sources including anonymized, aggregated Google Toolbar data from users who have opted in to enhanced features, opt-in anonymous Google Analytics data, opt-in external consumer panel data, and other third-party market research. All of this data is aggregated over millions of users and is powered by computer algorithms. The breadth and reliability of this aggregated data means that our traffic measurements are among the most accurate in the industry.
