can you find old domains that have not existed for a long time, go to archive and copy paste their content straight into your money site? does google "forget" these sites ever existed, or they hold these somewhere in their database and it's still considered duplicate content? If I google a few phrases from these articles, they don't show up so obviously they are not in the main index. but is there a backup index where they hold shit like this? I am looking for people who have actually experimented with this. what was your result? were you able to rank?
