How to redirect to home page on page not found 404
If you have a page that is not found, then google and others will penalize your site for not finding the page. Hence, you should handle that internally.
At least the easiest thing one can do is to redirect the site to the home page using .htaccess directives.
Homepage redirection 404
First create a .htaccess file if you don’t have one yet. Place this .htaccess file in the root of the website.
Then add the following line in the .htaccess file.
Options -MultiViews
RewriteBase /
RewriteEngine On
#if you have other redirect rules, have them here
#put this at the end of the file.
ErrorDocument 404 /
Mind you, the page you are going to redirect to should be relative path.
On the above file, those starting with # are comments and won’t be read by the server.
Hope it helps. Let me know if this helps you or if you have better method by leaving the comment down.
