Quantcast -- Audience Measurement, Lookalike Modeling, Audience Buying

You may already know about our top sites listing providing a comprehensive list of the top 1 million sites ranked by Quantcast based on the number of people that visit the site in a one month period. The list indicates whether the site is a Quantified Publisher via the use of our purple alpha seal. Recently we added a new white version of this seal indicating that the property is Partially Quantified.

Partially Quantified means that either the site is a participant in the Quantcast Marketer program or that while the entire site does not carry Quantcast Measurement Tags, certain subdomains do. For example, money.cnn.com and abcnews.go.com are the Quantified sub domains of CNN Money and ABC News respectively.

And don’t forget, you can download the top 1 million sites via the link at the bottom of the page, and it’s completely free!
