I've been following threads like this one since last week and suggested some patterns I've noticed. I think I just had a new insight that maybe some others can check on their results and concur or not.
We had a few primary pages drop from top 10-20 down to 100+ like others on here. I suddenly realized that the only pages we had affected were ones which were significantly 301 redirected TO! Is it possible G could suddenly be penalizing for 301 redirects? We 301 redirect most pages we remove, which are still backlinked by outside domains, to our home page, and it was majorly effected Wednesday dropping from #14 to ~#100. We also autorefresh our 404 page to our home page after n seconds. We 301 redirect another smaller group of deleted pages to a different page and it recently went from #2 to #18. Most others remained unchanged. Coincidence? I seem to recall there was some talk recently of blackhatters exploiting a 301 redirect bug to gain rank, could this be G fighting back and in the cross-fire catching innocent sites using it honestly?
BTW, I just noticed in the last 15 minutes that the page I mentioned above which went from #2-18 since last Wednesday is now back up to #5. Maybe the rest will return shortly!
Can you be more specific DirkZ on WHICH things have been no-nos?
