JS_Harris #:3708244 [webmasterworld.com...] A page of mine that had PR4 and drove solid traffic from search stopped sending any traffic two months ago. PR on the page is now grayed out. There is one affiliate link on the page, always has been. The page was manually penalized for its main term apparently. I'd like to hear more from affiliate marketers on how their visible pagerank changed

Not sure if the TBPR update is sufficiently finished yet and enough reports are in, but it could be that content related scoring on pages has increased in it's sensitivity as well, irrespective of the links into the page.

If the body content is duplicated [ as in affiliate / sydndicated content marketers ] those results may have further diminished in PR importance. My hunch is that if enough of those pages fall into that category, they may contribute to an overall site decline.

Externally generated duplicated content [ as in affiliate / syndicated content ], may not be the only consideration as I'm seeing internal scripted pages' TBPR greyed out. This indicates to me that internal duplicate content considerations may also cranked up a notch.

I think these and other changes were likely in play over the last few months, as the effects seemed to have been coming in reported in different ways.
