What Is a 404 Error?
A 404 error is an HTTP status code returned when a requested page can’t be found on the server — the URL doesn’t currently correspond to any live content.
Common Causes
404s typically happen because of a mistyped URL, a link pointing to a page that’s since been deleted or moved without a redirect, an outdated external link from another site, or a page temporarily unavailable due to a technical issue.
How to Fix Broken Links or Build a Helpful 404 Page
For pages that genuinely moved, a 301 redirect to the new location resolves the issue and preserves link equity. For content that’s truly gone with no replacement, a well-designed 404 page — offering clear navigation, a search bar, and links to popular content — helps recover a visitor’s experience rather than leaving them at a dead end. Regularly auditing internal and inbound links for unintentional 404s catches issues before they accumulate.
