301 redirect

What does 301 redirect mean?
It means that the user directly jumps to another domain name after visiting one domain name, which can be a jump between the same domain name, such as: cnaaa.com/ jumps to www.cnaaa.com/. It can also be a technology of jumping between different domain names. 301 permanent redirect has no bad effect on SEO, and the weight of page B will be conveyed to page B1. For search engine optimization and website optimization, it is a friendly message to search engines, telling it that this page has been permanently redirected , to prevent search engines from not finding the page.

Why do 301 redirects?
1: When we resolve the domain name to the server, we will resolve two domain names (with www and without www). If you do not set 301, you can access the two domain names to enter the home page, so that the weight of the home page will be scattered. . Therefore, 301 redirects must be set up. It is recommended to direct the ones without www to those with www. General users agree with www, which is more user-friendly.
Two: When changing domain names, if you don’t do 301 redirection, you will lose a lot of traffic, because users only know your old domain name. Through 301 redirection, the old domain name can be redirected to the new domain name, which can restore the traffic loss, which is beneficial to SEO.
