I confirm a PR update on 2nd Aug which give me a PR 4 from PR1. The problem is that since the 1st Aug, our impression and clicks decreasing horriblly. almost 30%-50% down. From google webmaster tool, i could easily see the almost all keyword ranking is dropping. The only thing i did in the past few days is updated a multi language version with not fully translated content(Similarity is around 50%), published online on about since 28th July Is there any possibility site been punished due to duplicate content(en version and partially fr and en version) Thanks for your opinions.
