What are the differences between the ‘Website’, ‘Syndicated’ and ‘Network’ traffic classifications?

A Network can be made up of both fully Quantified sites and distributed media (syndicated traffic), and we classify these differently to make analysis easier for publishers:

• Website traffic is what Quantcast sees from sites that are Quantified under your account.

• Syndicated traffic is what Quantcast sees coming from your tag, but not on a site you have listed as Quantified—for instance, if you distribute your widget to another site that isn’t yours.

• Network traffic is the sum of both Syndicated and Website traffic, indicating the full reach of all of your Quantcast-tagged assets.
