How to set up 301 on the website, in view of this question, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

Many novice webmasters are doing website optimization, because they have not dealt with the experience of website 301, so they feel that setting 301 redirection is a headache. Today, Zhengzhou website optimization company gives you a detailed explanation of how to do 301 redirection.

As for what is 301 and why the website should do 301, I won't repeat it here. I don't know how to understand these two questions before learning to redirect 301. Learning problems should know what they are and why! The following goes directly to the website to set up 301 detailed graphic tutorials:

A website has registered multiple domain names, and users who visit these domain names need to be redirected to one of the primary domain names automatically through 301 redirection. This is done in order to avoid causing a large number of copied content and being punished by search engines. Because from the point of view of search engines, each domain name is an independent station, and multiple domain names pointing to the same site will be recognized as the same site, content replication, light will not be included into the sandbox period, heavy will be directly by K.

301 redirection is also needed to standardize the URL.

Suppose there are the following web sites:

Http://www.heizhizhuwang.com/index.html

Http://heizhizhuwang.com

Http://heizhizhuwang.com/index.html

All do 301 redirects to http://www.heizhizhuwang.com (the selected standardized URL), and the search engine knows that http://www.heizhizhuwang.com is a standardized URL, and will transfer the weights listed above to the standardized URL.

Currently, Google transfers most of the weights, but not 100 percent. Baidu will transfer ownership weight. It takes 1 to 3 months for Google to identify, react and complete the weight transfer. Baidu's treatment of 301 is more conservative, and the new and old URL will exist in the database for a long time.

Apache server implements 301 redirection

If the site uses LAMP (Linux + Apache + MySQL + PHP) hosts, you can use Apache's mod_rewrite to rewrite or redirect URL. The following steps are required:

1. First, make sure that the mod_rewrite function is enabled.

Open the Apache installation directory\ conf\ httpd.conf with a text editor, find the line "# LoadModule rewrite_module modules/mod_rewrite.so", and remove the previous "#"

Continue to find "AllowOverride None" and change it to "AllowOverride All"

Then, restart Apache.

2. Put an .htaccess file under the root directory of the website where you need URL redirection. The file name is .htaccess, which cannot be created directly under Windows. You can save as with notepad.

3. Redirect to the desired page through regular expressions in .htaccess.

Examples are as follows:

Redirect the top-level domain without www to the domain name with www

Redirect page 301 to another page
