How to Fix a 404 Page Not Found Error
Find whether a missing page comes from a typing error, deleted content, a broken internal link or an incomplete redirect. Keep a useful custom 404 page for genuinely unknown addresses and monitor recurring errors for repair.
404 page not found often becomes confusing when responsibilities are unclear. A 404 response means the server was reached but could not find a resource at that address. The correct fix depends on whether the URL should still exist.
Start with the real situation
Find whether a missing page comes from a typing error, deleted content, a broken internal link or an incomplete redirect. A useful solution should remain understandable after the immediate task is complete.
Work through these checks
- Verify the address: Check spelling, capitalization, trailing characters and copied tracking parameters.
- Find the intended destination: Search the site or content system for the current version of the missing page.
- Repair the source link: Update navigation, articles, sitemaps or campaigns that still point to the old address.
- Add a relevant redirect: Redirect a retired URL only when a genuinely equivalent destination exists.
A short written baseline makes this work easier to review. Note the starting state, make a controlled change, and confirm both the intended result and nearby functions that could be affected.
What to avoid
Do not redirect every missing URL to the homepage; visitors still fail to reach the information they expected.
The useful outcome
Keep a useful custom 404 page for genuinely unknown addresses and monitor recurring errors for repair.
