How to apply 301 from one file to another file

Step 1: Add following code in your .htaccess file:

Options +FollowSymLinks
RewriteEngine on
Redirect 301  /file1.html   https://www.mywebsite.com/file2.html

The above code will permanently redirect file1.html to file2.html. So whenever a search engine or a visitor will look for file1.html, he will automatically be redirected to file2.html.

Step 2: Replace ‘mywebsite’ by your website name and file1.html and file2.html by your file names.

Another example:

Redirect 301  /what-is-event.html  https://www.eventeducation.com/what-is-event.php

Note: If the following lines are already there in your .htaccess file, then don’t add them again:

Options +FollowSymLinks
RewriteEngine On
