What Is a 404 Error?
A 404 Error is a server response that tells a browser or search engine that the requested web page cannot be found at the supplied URL. The page may have been moved, deleted, renamed, or linked incorrectly. A 404 response concerns one requested address, not necessarily the whole website.

Key Takeaways About 404 Error
- A 404 Error applies to a specific URL.
- Broken links and moved pages can produce one.
- A 404 Error is not the same as a server failure.
How 404 Error Works
A 404 Error appears when a browser requests a URL that the server cannot match to an available page. The server sends a status response, and the browser may show a standard or customised error page. The response concerns the requested address, so other pages on the same website may continue working normally.

Search engines can discover 404 responses through links, sitemaps, or previously indexed addresses. A useful review checks whether the URL should remain unavailable, redirect to a relevant replacement, or return to the website structure. Google Search Console can help identify reported URL problems, while server logs may show requests that do not appear in other reports.
Expert Note
When we review Technical SEO, we trace 404 responses to their source and assess the page’s intended destination. We check internal links, redirects, sitemaps, and important legal service URLs so the technical fix matches the website’s information structure.
404 Error in Practice: A Real-World Example
A law firm changes a family law service URL after revising its website, but an old blog post still links to the former address. Visitors who follow that link see a 404 Error until the link is corrected or the old URL is redirected to the relevant service page.
