What Is a 404 Not Found Error?
A 404 Not Found is an HTTP status code returned when a server has no resource matching the requested URL, telling both users and search crawlers the page doesn't exist.
A 404 isn't inherently bad for SEO — it's the correct response for a genuinely removed page. The risk is unintentional 404s on pages that still have links, traffic, or rankings.
