You may need to use different pair of eyes.
You know, I could use a new pair these days. ;)
While those three sites appear to be outside the AdSense discussion, there are a variety of "other factors" as to why those three may have lost traffic. One of them is inaccessible, another is a UGC Reviews Site (dime a dozen), and the other has a host of potentially fatal HTML errors along with other "visible" user challenges.
I look at some of those sites and there is "just too much going on" for the user. Things are flashing, stuff is moving, and I just might find the entire experience a bit too much. Content overload.
