San Francisco, California, June 9, 2010 – Quantcast announced today it is the first, and only, company to have its syndicated online traffic measurement service receive official accreditation from the Media Rating Council (MRC). Following an extensive audit process, the company has achieved accreditation by the MRC for select Quantified Publisher data. MRC accreditation provides customers of Quantcast’s free Quantified Publisher program the highest level of confidence of compliance with the Interactive Advertising Bureau’s (IAB) advertising impression and audience reach measurement guidelines. Millions of web destinations have chosen Quantcast’s free online measurement solution, which provides real time, accurate and reliable information on digital audiences.

MRC accreditation certifies that the Quantcast Quantified Publisher program and the company’s processes supporting this service adhere to industry standards for online traffic measurement. Quantcast did not seek accreditation for traffic estimates from ‘non-Quantified’ sites, those not using Quantcast Measurement tags, nor for its demographic estimates.

“We’d like to congratulate Quantcast on the accreditation of Quantified Publisher”, said MRC Executive Director, CEO George Ivie. “We were impressed with many of the innovations introduced by Quantcast in this product, and its accreditation is a notable step in the continuing evolution of the state of online measurement. We look forward to continuing our work with Quantcast to bring additional elements of its product line into the audit and accreditation process.”

The mission of the MRC is to secure for the media industry, and related users, audience measurement that is valid, reliable and effective. To merit MRC accreditation, Quantcast demonstrated that it:

  • Adheres to the MRC’s Minimum Standards for Media Rating Research and the Interactive Advertising Bureau’s (IAB) Ad Impression Guidelines, Digital Video Ad Impression Guidelines and the Audience Reach Measurement Guidelines
  • Provides transparency by providing full and complete information to the MRC regarding all details of its operation, including disclosing methodology details
  • Conducts its processing and reporting substantially in accordance with representations to its clients and the MRC, and
  • Submits to, and pays the cost of, thorough annual audits of its procedures by CPA firms engaged by the MRC

“The IAB applauds Quantcast for achieving MRC accreditation for select Quantified Publisher data. This milestone is a critical phase in meeting marketplace demand for full measurement service accreditation,” said Randall Rothenberg, President and CEO of the IAB. “By successfully completing the MRC audit, Quantcast is making a huge contribution to the credibility of online advertising metrics.”

The ad campaign measurement guidelines were developed by the Interactive Advertising Bureau (IAB) in conjunction with its members and representatives from the major online publishers and ad serving organizations around the world. Published in 2004, the guidelines address long-standing marketer and agency needs for a standardized method of measuring interactive advertising impressions.

“Quantcast measurement is completely free, but that doesn’t mean we don’t take audience quantification very seriously,” said Konrad Feldman, Quantcast CEO and Co-Founder. “Gaining MRC accreditation for our core measurement capabilities demonstrates our commitment to the millions of web destinations that have made us the world’s favorite audience measurement service”.
