As a relative newbie, I'm sure this is faulted somewhere. But in a very general sense: Assume I were to build a link directory to sites about widgets and then load it up with Adsense and other CPC advertising and one CPM exit console. If I then bought widget specific traffic at $3/1000 hits, I could probably turn a profit with even a pretty bad CTR on the CPC advertising.
Where am I faulty in this logic, because I must be missing something crucial... or else everyone would do this
