What is a 301 redirect?

301 redirect (or 301 redirect, 301 jump) is a status code of the header part of the HTTP data stream returned by the server when a user or spider issues an access request to the website server. Indicates that this URL is permanently transferred to another address.

How to determine whether a website has made a 301 redirect?

For example: When we enter the domain name fgba.net without www on the browser, it will automatically jump to the domain name https://www.fgba.net/ with www, indicating that this website has done 301.

Many large websites will perform 301 redirects. The main purpose is to achieve the preferred domain and centralized weight, so that all rankings and income of the website are concentrated on the preferred domain.

The domestic preferred domains all use domain names with www.

How does a website implement 301?

1. The virtual host is implemented on the IDC service provider website, and the virtual host service software comes with the 301 function.

2. The cloud server is implemented with Cloud Helper or Pagoda.

3. If you are using Sowai 6 system, B-end-domain name binding-will automatically implement 301 after filling in other fields.

In addition to solving the problem of URL standardization, 301 redirection also has many situations where 301 needs to be done.

For example: In order to protect copyright, the company owns multiple domain names with different TLDs.

Website revision also often requires the use of 301 redirects, such as page deletion, address change, URL naming system change, etc.

Staticizing dynamic URLs may also require 301, and convert the old, dynamic URL to a new, static URL.
