[thelist] PCData and their Information

     I asked this on Webmonkey and didn't get any nibbles.  Anyone here
     know how they do it?

     Can anyone tell me where the company PC Data gets their information?
     Over the past few months, my personal site has started to grow in
     traffic.  During this time, I have been contacted by several agencies
     wanting various information about advertising.  I have a friend who
     uses PC Data and he told me we have showed up on the list.

     My question is this.  Where do they get their information?  They have
     avg visitors, time spent, page views ....... This info, I do not give
     out.

     Can anyone shed any light on this?

     thanks
