Where to use it
In an online shop most 404s come from products that no longer exist. Google still has the old URL, someone clicks it from a search, and finds nothing. An ecommerce 404 page that says “sold out” in a friendly way explains what happened, and the “Keep shopping” button puts them back in the catalogue straight away.
If a product has a clear replacement, a redirect to it or to its category is better than any 404. Use this page for everything else. The white card and red accent fit most shops, and the title, message and button text are all editable.
