404 Error
A 404 Error indicates a missing webpage, which can harm user experience and SEO.
Definition
A 404 Error occurs when a user tries to access a webpage that cannot be found on the server. This typically happens when the URL is mistyped, the page has been moved without redirection, or the page has been deleted altogether. When a 404 error is encountered, the server responds with a 404 Not Found status code, indicating that the requested resource is unavailable. For both users and search engines, encountering a 404 error can lead to frustration and a poor user experience. To mitigate this, website owners should implement proper redirects or a custom 404 page that guides users back to relevant content.
Why It Matters
404 errors can negatively impact your site's SEO by causing search engines to devalue pages with broken links. A high number of 404s can also lead to a poor user experience, increasing bounce rates and reducing overall site engagement.
Example
For instance, if a user attempts to access www.example.com/nonexistent-page and receives a 404 error, they might be redirected to a custom 404 page that suggests visiting the homepage or popular articles instead. This helps retain visitors even when specific content is unavailable.
