# 404 page

A **404 page** is a standard error page displayed by a website when a user tries to access a URL that doesn't exist or has no corresponding content. Its benefits include providing a user-friendly error message, keeping users on your website by redirecting them to other pages, optimizing SEO through internal links, and offering contact or help information. It enhances user experience and engagement while addressing navigation errors.
