The search engine is not exclusive reprint, because the content that reprint can let the reader know what they want. But there is a degree of everything, webmaster to grasp the good yardstick.

And let you spend a lot of time recovering, to measure you are not junk site, once a pan-station popular period, Baidu once help new station all pull to the sandbox, Baidu search is not the first position, and then you are the real station will always do it will slowly give weight, if you are a pan-station that only give up, Use can be wrong to kill the way to stop the pan station's pace.
