This question is bothering everone who's involved in SEO and article marketing. No guess, just precise evidence how Google actually acts towards duplicate content Are you afraid of duplicate content? Are you using duplicate content?
I try and block duplicate content on my forums by "Disallow:"ing all print pages, previous/next links and so on. That can't hurt, right?
search engines dont like duplicate contents, some can escape but not all, to rank higher one can get vanish from search engine result pages by using duplicate contents. so cant take the risk.
