A 404 error page is a great way to enhance the user experience and support SEO. For users, it prevents frustration by providing clear explanations and navigation options like search bars or links to popular pages, keeping them engaged and helping them find relevant content. For SEO, it signals to search engines which pages are no longer available, maintaining the site's search ranking and overall health.

With the Imagely theme, it's easy to add a 404 error page on your site to start creating a smooth user experience.

From here you'll be able to set whether to use a blank page or use elements from your site and even adjust the width of the error page.

And that's it! Now you're ready to provide users a helpful experience while maintaining your SEO presence.
