Quick answer: A 404 is not always something to “redirect away.” The correct response depends on whether the missing resource has a true replacement, was removed intentionally or never existed.
Restore when the page should exist
If an important page disappeared because of a publishing mistake, restoring it at the same URL preserves the cleanest user experience and avoids unnecessary redirect logic.
Redirect only to a genuine replacement
When content moved, add a permanent redirect to the closest equivalent page. Do not send every deleted URL to the homepage; that hides the problem and may confuse users.
Leave a meaningful 404 when there is no replacement
If the content is truly gone, a useful 404 page with navigation or search can be better than an irrelevant redirect. 410 can be used when you intentionally want to signal that a resource is gone.
Update internal links
After adding a redirect for legacy visitors, change your own current links to point directly to the final URL. This prevents redirect chains from becoming part of the new site structure.
Check external high-value references
You cannot edit other websites, PDFs or printed material. For those, keep the legacy redirect working or use a managed stable-link layer for future campaigns.
Use the tools
For a live URL, URL Checkup combines redirect tracing, metadata, tracking detection and health scoring. If the link is already broken, Smart URL Recovery can search the same site for likely replacement pages. For long-lived public links or printed QR codes, Rescue Link adds a stable managed destination.
Important limitation
