Seven common methods to realize 301 redirection

301 redirection is no stranger to webmasters. From website construction to directory optimization, changes to site directories cannot be avoided. In this case, old addresses may still be saved in users' favorites and search engines. 404 errors will occur when opening these links, resulting in a poor user experience and loss of a lot of traffic. Today, Yuanyuan will share with you seven ways to achieve 301 redirection.

From the point of view of search engine optimization, 301 redirection is the most feasible way to redirect after the change of website directory. After you change the address and use 301 redirection, the search engine will only index the new address and transfer the original links under the old address to the new address, and the above actions will not affect the ranking of the site in the search engine.

The most direct way to achieve 301 redirection is to edit the .htaccess file. For more information about how to use the htaccess file, please click here. The garden needs to remind you that before operating on the .htaccess file, be sure to back up the original .htaccess file to avoid unnecessary trouble caused by modification errors.
