Hello, For many keywords one of my page- Dill Mill Gayye Songs used to rank top of google, like Dill Mill Gayye, Dill Mill Gayye songs etc. But now it has fallen badly. I tried to find a reason an I saw 2-3 sites copied my full article without linking back to me. They copied each and every word. Here's it- http://tvstarone.blogspot.com/2009/03/dil-mil-gaye-show-is-all-about-learned.html And 2 more. The bad part is that I cant find how to contact them. There is no contact info. But can this be the reason for fall in rankings.
I think this is normal. It happens sometimes. Have you copied this your contents from somewhere else ? there is something going in google. They are blacklist, penalizing lots of sites. And mainly they are warez site. Check out your webmaster for any error too.
If another site is copying your content you can notify Google with a DMCA notice. They'll review it an ban the other sites if they can determine that you are the original author. Here's a link with more info: www.google.com/dmca.html
i dont think its a penalty as you had the original content indexed before they did, has to be something else...
I think that you have been cheated by someone and you should report it to Google as soon as possible. If you have the original content then you should prove it to Google and you will surely receive help. In future you will be protected from such attempts.
Thats not a problem of duplicate content if your page was crawled and cached by Google prior to those pages who copied your content. I guess you need to build some backlinks in order to get back the position.
