How Smart Custom 404 Error Page works
Show full descriptionShow less
Bringing visitors to your website takes time and effort. Every visitor is important. The default 404 error page of most themes does not provide any information on what to find on your site. A first-time visitor, who does not know you, is left in a dead end and leaves your website. Set up a helpful custom 404 error page to keep them on your site!
This handy plugin allows you to easily create your own 404 error page without any effort and it works with almost every theme.
