Welcome to WebmasterWorld Guest from 184.108.40.206
I did not do anything wrong! I think google team thought my content is spam, absolutely not, the content of those pages are written and submitted by our publishers who also submit the same content to the other websites and I looked at those websites they have not been punished!
However I contacted them but still did not receive any reply yet.
Any suggestion will be appreciated.
Are those PR0 pages indexed in Google?
Toolbar PR is notoriously buggy, I wouldn't pay too much attention to it - watch the SERPS and your logfiles, not the little green bar.
See Macro's post and the sub-heading in there "Help, I've lost all PR!".
further proof I think that pr makes little difference
I have home page pr6 which rarely gets hits via g
i have internal pages with pr0 which have ranked number1 for a very competitive phrase for about 4 years
wouldnt worry about pr anymore - dont think g does
Articles and content that is written first and placed on another higher ranking site will take precedence. Apparently from what I have heard in some circles Google may be testing a way to simulate reading and testing content from a more 'human perspective'. Is it possible your pagerank has been dropped to 0 because Google deems only those pages duplicate content? Possibly this is a new thing applied to newest updates?
home page had PR 6, now dropped to 4. All other previously high ranking pages are now at PR0 and basically gone. I have done nothing wrong here. Google has a problem handling permanent redirects it seems. My old pages that had been redirected to the current pages a long time ago were never completely removed from their index, just pushed far back, so 2 urls existed that went to the same page.
It seems a duplicate content filter was definately applied, and sites punished. In my opinion, they need to handle their redirects correctly first. Im still showing up good in this DC
but its unlikely these results will spread.
