This is not new news. Suprised its getting up votes. I would say most marketers are well aware of this. We try and measure down funnel. You learn who are the successful networks and who are not.

I and markwters around me have looked at this in ever company I've been at. Maybe Ive had a rare experience but I doubt this.
