I was just at another forum and someone with a 15 year old site has the same issue. What I found by copying about 200 words from an article, and searched for exact match was a Facebook page ranked over him with a posting time of 8 hours.
Looking into this I have found that the facebook page copied his article word for word and ranked over him. His article was published in march 2013. his site has been sliding for 2 years.
I'm going to do a test and post my articles to my fb page and see if they rank over my site, at least ill start getting credit for them.
