I have a PR3 blog just over 1 year old and have been ranking very well. Just done an overhaul of the pages added new images and moved the same content around abit and i have noticied i have dropped all my rankings and PR for those pages. I also added wprobot and setup a couple of categories to post too. If i do site:mydomain.com all my pages including my main domain and new auto blog posts will come up but, none of the pages i updated will show. But if i do site:mydomain.com/mypage/ some of the pages show. Do you think this could be something to do with google dance or getting penalized for the autoblog i added (dupe content)?
