For Baidu, it is not recommended to change the domain name or change the original page URL in the process of website revision, as long as you do so, website ranking and inclusion will definitely have an impact, how much impact, mainly depending on how you operate, the following is a brief introduction to the revision behavior of several notes:

First, the website revision try not to move the URL

First of all, again，Unless absolutely necessary，Never change your domain name，This includes changing the URL of the original page，Try to make a page that targets a unique URL，It's like each of us has a unique name，In real life，We changed our names，People will at least know you when they see your face，Can be for web pages，You changed the URL，Search engines will count it as a new page，Even if you do a 301 jump and submit a rule change，There still needs to be a weight transfer process，In the process，Traffic will also be somewhat lost。

What's more, after some websites are revised, the 301 jump, revision rule submission, and dead chain processing are not perfect, which will lead to the weight of the original page not being transferred in time and 100%。

Two, old and new urls should have rules to follow

Well, if you really want to change, whether you change the domain name or modify the original URL structure, the old and new page URL must have rules to follow, which is good for the later 301 jump, and the webmaster tool submission revision rules, such as your old URL is www.a.com/2016/123.html, then try to keep the ID of the new URL the same, for example, www.b.com/2016/123.html。

Third, do a good job of new and old URL301 jump relationship

Just change your domain name，Changing the original URL structure is fine，After completion，Be sure to redirect the old page 301 to the corresponding new page，Instead of violently jumping all pages of the old domain name to the home page of the new domain name，The content of the two pages before and after the 301 jump must be consistent，The 301 jump is only the URL jump and not the content change，Let's say you dial 110，Finally, the call was transferred to 10086，Is not very abusive heart，The same goes for a 301 jump。

Replace the link to the old URL in the new page

After the website is revised, the new page, especially the links in the body of the article, there are still many links pointing to the old domain name (old URL), through the program or manually replace the above links to the new page。As well as the friendship links exchanged before and other websites, try to change to point to the new domain name。

Fifth, submit revision rules in Baidu webmaster tools

As long as the new and old pages have rules to follow, you can submit the revision rules in webmaster Tools;If there are no rules to follow, you can only submit old and new urls, but this method is slow to identify and difficult to operate。Submitting the revision rules will help Baidu better execute the replacement relationship and quickly transfer the weight to the new page。

6, check the new page for dead links and submit the dead link

Because the domain name or URL structure changes，It leads to a lot of dead chains，Some webmasters have a hard time discovering the existence of a dead chain，At this time, it is recommended to use third-party software to crawl all the links，Find and collect dead chains，And put the dead chain in a text document，Upload server，And the file address is added to the webmaster Tools dead-chain commit。There are a large number of dead chains on the website, which will affect Baidu's overall judgment of the website。

After doing the above steps，A couple days later，Baidu began releasing the rankings of new pages in its search results，But it's impossible to replace all the old pages at once，Even a year later，Old pages may still appear in the search results page，But as long as the overall site traffic returned to the revision before it should not be surprised，In addition, the 301 jump relationship between the old domain name (old URL) and the new page is recommended to be retained，The longer the better，Try not to go below six months。
