One week update:
Google visits continuing at pre-Panda levels for the pages, now up to a dozen, moved from the 80% down Pandalized site to the 300% up Pandaloved site. No signs of the move in either WebMaster Tools account yet, and Googling the original domain name still shows results for pages that have been moved, though it correctly identifies them as being located on second domain.
The second experiment, moving several dozen pages from my less-Pandalized site to a new domain with no Google status has also resulted in a traffic boost, but not to pre-Panda levels, more like halfway there. While all of the feature pages are close to double week-on-week, the visitor shares aren't distributed the same way as a year ago. This I would attribute to non-Panda changes in the algo and changes in competition.
I suspected from the start that the transfer to the previously unused domain wouldn't be as effective as the transfer to the Panda beloved domain, but I wanted to try it both for the sake of the experiment and to keep the subjects segregated. It will be interested to see if the two moves are treated differently if and when the mother-in-law crashes the honeymoon.
Side note that maybe should get a thread of its own, but the page I rewrote (@2,500 words) from top to bottom because Google was completely ignoring heavily pirated and syndicated sections, recovered appreciably as soon as it was reindexed. Last Tuesday it got 1 visitor from Google on the new site, yesterday it got over 60.
I really reworded it as opposed to rewriting it. The meaning of the text is the same, just expressed differently, though with the same basic vocabulary. I'm fooling around with doing the same for some other heavily infringed pages, even though it's a lot of work and probably hurts the quality a little since the language is so forced. The other pages in the group were from the same original date, so it didn't have anything to do with the age of the original content.
