If a page on your website no longer exist and you want to redirect it to your new page or website then you can use the .htaccess file for redirection without waiting.
Redirect from a page/directory to another domain or the main domain:
Redirect from a specific page to a 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.
