A 404 error occurs when a web page can’t be found. This can happen if the URL is incorrect, the page has been deleted, or moved without updating the links. For users, it means the content they were looking for isn’t available. Website owners should regularly check for broken links and create custom 404 pages that help visitors find what they’re looking for. Tools like Google Search Console can help identify and fix these errors, improving the user experience and maintaining SEO health. Check out more details about 404 Errors!
