404 errors (“Page Not Found”) occur when a link points to a page that no longer exists or the URL is misspelled. These hurt user experience and SEO, so fixing them is important.

• URL slugs changed but no redirect set up
• Deleted pages still being linked internally or externally
• Typographical errors in links or image paths
• Linking to pages in the wrong case or with trailing slashes
• Removed or changed resources without updating references

1. Use Google Search Console or similar tools to find reported 404s. ([similarweb.com](https://www.similarweb.com/blog/marketing/seo/404-not-found/)) 2. Check your site’s internal links, menus, and footer for broken references. 3. Visit the URLs in a browser to confirm whether the 404 is live. 4. Review recently moved or renamed pages to see where old URLs might still be active.

• Correct misspelled URLs in links, menus, and resources across your site.
• If a page has moved, set up a 301 redirect from the old URL to the new one. ([brightseotools.com](https://brightseotools.com/post/how-to-fix-404-errors-for-better-seo))
• If using WordPress, resave permalink settings to regenerate rules. ([brightseotools.com](https://brightseotools.com/post/how-to-fix-404-errors-for-better-seo))
• Use a custom 404 page that includes navigation or search to help users find alternative content.
• Deactivate or correct external links (on partner sites or directories) that lead to 404s.

• Maintain a regular audit schedule for checking broken links.
• When renaming or moving content, always plan for redirects.
• Use tools or plugins that monitor for 404 errors and notify you.
• Avoid changing URL slugs unnecessarily.
