I certainly hope that new algorithm will sieve out all copies and will put an original post on the top of Google’s search page. The “new” algorithm is nothing new though ➡ years ago it was good enough to sort the search results by date to get the source text. It used to work like that not too long ago in groups search. Why not to return to search results by date, huh ❓
I also hope very much that new algorithm will first hit the most annoying content farmer on American server I know.
So far however I can only tell that the new algorithm is handicapping their own Google sites over anybody’s else. I posted copy of my WordPress text on Blogger a few days later and now the secondary Blogger post has higher ranking than the original WP text.
