But from their own optimization means, can say did not do sorry Baidu thing, the site's article update is original and false original combination, although many articles are from other people's website excerpt from, but at least have done processing, Outside the chain is not to mention, are their own manually added, but also to achieve the breadth of the chain, what blog, forum, soft text, questions and answers have been used; Does the website appear this situation, the true reason of Baidu itself?
