Below we analyze the 301 redirect more actual situation!

1, situation one, my old domain name is to put some yellow content (just for example), such as: pictures, articles, in some cases brought a lot of traffic, every day may be over million.

2, the situation two, my old domain name all the content is in line with national laws and regulations, but using the SEO black hat and other improper means to improve the old domain name weight and have a good ranking and flow. And then through the 301 redirect to the old domain name heavily directed to the new domain name.

Summary of the above two cases, are likely to exist, if there is a 301 redirect Baidu will only pass the weight of the case will appear in both cases.

The above two situations are Baidu standing, webmaster position, will take into account the situation, but you have not considered the new domain name competitor's situation?

* If 301 redirect to the domain name is no benefit *

3, the situation three, competitors: if the peer competitors use 301 Redirect to the new domain name does not benefit the factors, through some illegal or not in line with Baidu normal optimization practices of the Site 301 Redirect to your new domain name, artificially caused by the new domain name Baidu is not friendly!

Summing up the above points, 301 redirect to the new domain is really beneficial? Baidu algorithm engineers will use what algorithm to deal with this 301 redirect problems? That's really hard to say! So I suggest try not to use 301 Redirect, can not do under the conditions, Must ensure that the old domain name before redirection is not Baidu K station or the site itself is the normal SEO method optimization, content is also legal!
