Ziff Davis Secretly Paying Sites To Track Users

First time accepted submitter jonez450 writes "Times are tough in the advertising business. But PCMag publisher Ziff Davis has come up with a new plan to gain a competitive edge: Paying other tech sites $1 CPM to place tracking code on their sites in return for data about their users via JavaScript. The company is also offering free content in return, but the 'private' Ziff Davis Tech Co-Op doesn't want anyone to know what they are up to."
