How to Find and Fix 404 Errors Without Losing Useful URLs

Learn how to separate broken links from intentionally removed pages and choose the right fix for each URL.

Group errors by cause

Export the affected URLs and group them into internal links, external links, old content, deleted products and malformed URLs. A long list of 404s is not automatically a problem if the URLs were never intended to exist. Prioritise URLs with internal links, backlinks or historical traffic.

Choose the correct response

Restore a page when its content is still needed. Use a 301 redirect only when there is a genuinely relevant replacement. If a page has been permanently removed and has no suitable replacement, a real 404 or 410 is generally clearer than redirecting everything to the homepage.

Repair links at the source

Update navigation, related-content links, XML sitemaps and campaign links that point to broken URLs. Redirect chains should be simplified so links lead directly to the final destination.

Verify and monitor

Retest the final URL and inspect a sample of referring pages. Track whether the errors recur after deployments and keep redirects documented to avoid loops or unnecessary chains.

Practical next step: Apply the checklist to one representative page, document what you changed, and recheck the result rather than assuming a single edit guarantees rankings.

Search systems and platform policies change. Verify current requirements against the relevant official documentation before acting on time-sensitive technical advice.
