Now the spread of network resources is very common, you work hard to write the article so that others can be two seconds to get away, in the end may be the search engine that you are plagiarism, this kind of thing is not new, because the search engine to determine whether the original material is a lot of factors, a careful analysis, roughly summed up the following several factors:

1, the PR value of the page: two pages have the same article, search engines will generally think that the PR value of the page for the original

2, whether the first time included: If your article published, by another site, the search engine did not first crawl your page, but first crawled the site page, so unfortunately, you are likely to be considered plagiarism

3, the authority of the site: for example, a "human body tester," a very classic technical articles, although you have struggled to find a lot of information to write out, if in a short period of time by an industry website or product official website to quote, search engines are likely to determine the source of the original to be more authoritative site, you will be out

4, Domain name registration time and build station time: The sooner the registration time and the establishment of the station, the more likely it is to be the source of the original. But for now, these factors are still not enough to make the search engine completely correct to determine who is original, because these factors are not absolute search engines are followed.

Google in this regard to do better, because it is more complex reference factors, crawling is more timely, and Baidu is relatively poor, the construction of the station time seems to be Baidu more value factors.

Sometimes copied content page PR value than the original content of the page PR value is higher, this phenomenon is more complicated to explain

Page information is original, not a webmaster, to see the search engine specific algorithm, each search engine has different criteria for evaluation, only the search engine algorithm is more and more perfect, the controversy will be gradually reduced.
