What Is a 404 Error?
A 404 error (also known as "Not Found" error) is an HTTP response status code indicating that a user has attempted to access a webpage or resource that cannot be found on the server. This error occurs when the server can successfully communicate with the client but cannot locate the requested content. The "404" designation is part of the standard HTTP response codes, with the "4xx" series indicating client-side errors.
Impact on SEO and User Experience
A 404 error can significantly impact both search engine optimization and user experience. While occasional 404 errors are normal and even expected on active websites, excessive or poorly handled 404 errors can create several problems:
From an SEO perspective:
Wasted crawl budget when search engines encounter too many 404 pages
Potential loss of link equity from broken internal and external links
Negative impact on user engagement metrics
Possible reduction in search engine trust signals
For user experience, encountering a 404 error can lead to frustration and site abandonment. However, when handled properly, a well-designed 404 page can actually improve user engagement by providing helpful alternatives and maintaining brand consistency.
