My site has been up for about half a yr now. Up until about a month ago, I was holding PR2. Then all of the sudden, it dropped to PR0. (this was before the last big update came through a few weeks ago) Some of my pages PR are "not ranked" but a lot of my most vital landing pages went to PR0. I am not getting any warning messages from google but i did find some not so SEO friendly stuff to fix such as: duplicate metas and a bunch of junk sites backlinking to me without my awareness. So i fixed most of the duplicates (mostly query/parameter stuff) and sent out a "remove me" notice to the junk sites as well as a disavow list to google. So now I wait. But I was wondering if anyone could help me or point me in the right direction to find out if i've been penalized or just sandboxed. Much thanks in advance.
