Maximillianos, that's true to a degree. Very sticky community sites, for example, have notoriously low click rates on ads.

On the other hand, the fact that a property keeps people onsite and brings people back via bookmarks adds value in another way. These sites don't have to advertise to maintain traffic, and they don't have to worry much about rankings.

If I had a major income site that derived virtually all of its traffic from Google searches (not counting navigational searches, which seem to be growing), I'd sleep poorly at night.
