If a page on your website no longer exists and you want to redirect it to your new page or website, then you can use the .htaccess file for redirection without waiting.
To do so, you will enter the following in the .htaccess file depending on your needs.
Redirect from a specific directory to another domain on the main domain:
RewriteEngine on
Redirect 301 /mypage.html http://example.com
Redirect from a page to another page
Redirect from a page/directory to another page
Redirect 301 /oldpage.html /newpage.html
Now, whenever you open the URL “example.com/oldpage.html”, it will automatically redirect you to “example.com/newpage.html”.
