I recently moved a website from one host to another, along with a restructuring. Somewhere in the midst of this massive job, some important content was accidentally left out.
This content was a long article and I discovered just now that it was never moved to the new site a month ago. So, I was curious if it had been misplaced on another page and went to Google and searched for a block of text from the article and found out the the article has been copied (sometimes in whole and verbatum) by several other sites.
I was the author of the article, so I know it was posted for the first time on my domain. If I repost this content on my website on the page it was accidentally left off of, will I incure a duplicate content penalty on the back of those duplication at those other sites or will I recover my rightful place as the canonical source of that material?
Thanks in advance for any help/advise you can offer.
