A 404 error, also known as a “page not found” error, is an HTTP status code that indicates that the requested webpage could not be found on the server. 404 errors occur when a user attempts to access a URL that no longer exists or has been moved without a proper redirect in place. These errors can occur for various reasons, including broken links, outdated URLs, deleted pages, or misspelled URLs. 404 errors can negatively impact user experience and search engine rankings, as they can frustrate users and prevent search engines from properly indexing and ranking website content.

To address 404 errors and improve website usability and SEO, website owners should regularly monitor their website for broken links and outdated URLs and implement redirects or create custom 404 error pages to guide users to relevant content. Custom 404 error pages can include helpful navigation links, search functionality, and a friendly message explaining that the requested page cannot be found. Additionally, website owners can use tools like Google Search Console to identify and fix 404 errors and ensure that their website’s navigation and internal linking structure are optimized to minimize the occurrence of broken links in the future.
