how does quantcast get their data?

  From panels/ISPs, -OR- You insert some js in your pages, and it's "quantified". They actually have some pretty cool stats, and exact numbers unlike alexa.

    problem 1: phones don't do js problem 2: phones don't have panels problem 3: phones don't connect to isp's they connect to carrier wap gateways. One attempt to track mobile is from Opera but it's highly skewed to the type of people that have Opera on their phones and the activity that's significant for them: http://www.opera.com/mobile_report/ http://www.opera.com/mobile_report/

      Ah presumably most of the usage is via WAP then?
      • gustaf 18y ago
        It's mobile web yes. most of the mobile web browsers renders XHTML and most traffic is XHTML

          FYI, our largest devices are Ipod Touch, Samsung Instinct, Blackberry, Nokia N95 and Sony PSP.

      Old phones. iPhone, Android -- these are the phones of the future. In three years, most people will probably have WebKit or Gecko running on their phone. The iPhone is already the best selling phone in the US.

    So, for quantified sites, audience composition is extrapolated from ISP data based on what? The Quantcast provided explanation (http://www.quantcast.com/docs/display/info/Next+page4 http://www.quantcast.com/docs/display/info/Next+page4) is pretty light on concrete details of how it extrapolate demographic data from cookie info. Would love to hear a straight forward answer for this one. My clients love the data available, but give it low validity because not clear how its derived.
