We all know that the appearance of 404,404 error pages is often the website information of the revision, removal or deletion caused. So that everyone through the search engine or other favorite Web site may be a 404 page, then we introduced in the last article with the transformation of the 404 pages to avoid embarrassment, then there is no other than this way? This is the 301,302 I'm going to say today. I do not use professional terminology to express, PS: In fact, the author expressed a problem! Feel popular to speak, is for the aspect everybody popular understanding!

301 refers to permanent redirection, which is popular when users visit a Web site and are redirected to another URL. After implementation 301, the new Web site completely inherits the old Web site, the old site rankings, etc. completely clear zero.

1, 301 Advantage

We all know that after the operation of the website, the WWW site and the site without WWW is included and ranked is not the same? The consequence is that the weight of the site can not be unified. If you use 301 Permanent Redirect, then put the ranking of the site's outdated URL weight to another up. This plays an important role in enhancing the weight of the website.

Secondly, we said that the 404 page of the appearance of embarrassment, if effective use of 301 to redirect the error page to the correct page. That avoids the loss of website traffic. Also ensures that the site's exposure rate.

2, 301 User Experience

Write 301 user Experience is actually I think I just started to do the site, at the beginning I want to do a navigation station. See 2345.com Navigation site is quite cattle, nothing to do to the Ministry of Investigation and check the site's record. I was stupid. There are more than 10 URLs linked to this navigation station. Now think about it, 2345 fully effective use of 301 permanent orientation, so that the effect, not only to enable users to find a multi-channel navigation station, followed by the site's brand is also a big marketing. With the development of small accumulation, now I would like to say that no one does not know 2345 navigation station!

3, more than 301 years in effect

On this issue, in the forum everyone will ask how long after 301 permanent orientation will be effective, everyone seems very anxious, that is, just see a 4 months to do 301 effective experiment. I'm sure 301 redirects are basically in 4 months or so. I don't know why everyone wants to hurry up, but I want to say, don't worry, do what you have to do.

302 refers to temporary redirection, and the common definition of 301 permanent redirects is the same. It's a matter of time! One is permanent, the other is temporary. After implementation 302, the old web site has no impact, but the new Web site will not have rankings.

1, 302 short-term benefits

For 302来, individuals prefer 301. How do you say that? 302 of the role is mainly in the short-term utilization and efficiency. In the Web site for the content of the revision and restructuring of the appropriate use of 302 temporary orientation, will not allow the old site to produce negative marketing.

2, 302 negative benefits

Here is going to say URL hijacked. About 302 and URL hijacking relationship. We can understand that. Search engine in the index of a Web site, if there are 302 settings will be automatically transferred to the new Web site. But the key is that some people who cheat will set the new Web site to be relative to a very long and cumbersome URL. Search engines, such as code, are not people, the site for the search engine friendly, the previous site is more friendly, so the search engine will be very willing to search the original site.

It is because of the existence of some cheaters that 302 has negative benefits. So in today's search engine, a bit unfriendly to 302, there is the possibility of manslaughter. This is also the gain for SEO.

301 and 302 have the same utility, why not choose 301?

For the Site 301 and 302 settings, some will give such cumbersome code, I am sorry, most of the webmaster estimates do not understand, here I would like to say that these settings in the space operator's background can be set up by the user. Even if not, you can find IDC operators to help!
