Welcome to the Q&A Forum

Thank you, that was what I thought, but I needed someone else opinion to be sure that I wouldn't get penalized because of that. Thanks for the link also! I appreciated your help. Fabrizio

Thank you so much! I really appreciated your reply which clarified everything for me. I will follow your advice! All the best,

Thank you, I think you clarified the problem very well. Appreciated your help!

Thank you Peter, I got your ticket reply. That makes perfect sense, and as Dr. Peter pointed out on a different thread: http://www.seomoz.org/q/why-seomoz-bot-consider-these-as-duplicate-pages I was discussing this issue further, I was confused by your report. Thank you again for your help and I hope you will improve your report interface to avoid such confusion related issues in the future. Best, Fabrizio

Yes, I will look into doing that on GWT. Was a nice and useful chat indeed! Thank you again.

Never mind, I have just found your site... thank you again!

Peter, I have added a new editorial review on the page: http://www.virtualsheetmusic.com/score/Moonlight.html Also, by looking again to your suggested http://www.origenmusic.com/free-piano-music.html, that page is quite different from ours and it is not dedicated solely to that specific title (Moonlight Sonata). So, I don't think the possible "duplicate "issue may be the real problem (not for that specific URL at least). Any more thoughts? Someone else? Pretty desperate to understand what happened on those pages to drop so much in rankings!
