Compete does not work via Spyware alone. They're using a lot of ISP data as well.

  Compete is horribly inaccurate. It's not even good for getting trends most of the time. Fortunately, with both these sites we don't even have to guess, they're both directly measured on Quantcast: http://www.quantcast.com/search.jsp?domain=posterous.com http://www.quantcast.com/search.jsp?domain=posterous.com http://www.quantcast.com/search.jsp?domain=tumblr.com http://www.quantcast.com/search.jsp?domain=tumblr.com They're both trending upwards, but Tumblr is going up faster and is far larger than Posterous.

    How does Quantcast directly measure?
    • staunch 16y ago
      Tumblr and Posterous insert Quantcast Javascript into their pages, and it includes their unique Quantcast ID in it. The same way Google Analytics works. From Posterous: <!-- Start Quantcast tag --> <script type="text/javascript"> qoptions={ qacct:"p-16ewveTurfCCM" }; </script> <script type="text/javascript" src="http://edge.quantserve.com/quant.js"></script> <noscript> <a href="http://www.quantcast.com/p-16ewveTurfCCM" target="_blank"> <img src="http://pixel.quantserve.com/pixel/p-16ewveTurfCCM.gif" style="display: none;" border="0" height="1" width="1" alt="Quantcast"/></a> </noscript> <!-- End Quantcast tag -->
