If you don’t set up a custom error page, your server will display a default error message, which is typically plain, unbranded, and offers little guidance.
This can lead to:
-
A poor user experience, as users may feel confused or frustrated
-
A lack of consistency with your website’s design and tone
-
Missed opportunities to redirect visitors to useful pages (like your homepage or contact page)
Without a custom error page, visitors encountering issues like 404 (Page Not Found) may simply leave your site instead of staying engaged.
