Why not take the WWW Baidu snapshot ranking well

Recently, found that Baidu ranked most of the pages of the snapshot is not with the WWW, and we go in from these snapshots, we will be surprised to find that these sites have done 301 Redirect to the WWW domain name, then why Baidu also shows no www snapshots? is not the 301 redirect to Baidu has been invalid?

First of all, we need to know that 301 redirect is really a Web page that can automatically jump to a custom URL, and as for Baidu has no effect, there must be some before, because the previous Baidu snapshot shows are 301 redirect after the custom URL, so said before the 301 redirect is effective, and the recent Baidu algorithm constantly update jump , most likely caused by a database error. As shown in Figure 1, we can see from the diagram that these sites have done 301 redirects.

　　

We can see that these sites are usually issued outside the chain and the chain are all with WWW Web site, and with the WWW snapshot of the Web page is not no rankings, but not with a snapshot of the WWW rankings, guess there may be those outside the chain of reaction, Baidu hate those flooding outside the chain for it. And we recently also found that the impact of the spider now is not very big, in our website log can be found, although you have a lot of chain, but the number of Baidu Spider visit is still unchanged, it is conceivable that Baidu Spider's dependence on the external chain has not been so high.

　　

Another possibility is that Baidu is intended to let webmaster know the effect of the chain has not been so big, only pay attention to the content of the site itself is the feasible way. Also only let the webmaster know the direction of their own rectification, in order to make Baidu more high-quality content to show to the user. In the last two or three months, Baidu many times to update the algorithm, so that many of the site rankings, and Baidu's purpose is to purify the content of the site, for those who do not have the material content of the site, the users of the site are not disadvantageous, the most serious is the medical industry, the content of plagiarism is very serious, but also the Therefore, we must pay attention to the content of the site itself update and writing, rather than spend so much unnecessary time to junk outside the chain, this is the future of the SEO need to reform the new direction.
