Broken Links: How 404s Damage AI Trust

Broken links signal neglect—that a site isn't being maintained. As a key Trust signal in EEAT, link maintenance matters. When AI crawlers or users encounter 404 errors, it suggests content isn't kept current. Internal broken links hurt navigation and user experience. External broken links indicate outdated research or citations. Both damage trust.

Why Broken Links Matter #

Broken links damage trust in multiple ways:

• User frustration: Clicking links that go nowhere is annoying
• Maintenance signal: AI associates broken links with neglected sites
• Authority loss: Citations to dead pages don't support claims
• Crawl waste: Search engines waste crawl budget on 404s
• Link equity loss: Internal links to 404s don't pass authority

Fixing Broken Links #

For Internal Broken Links #

• Update the link: Point to correct URL if content moved
• Set up redirects: 301 redirect old URLs to new locations
• Remove the link: If content no longer exists
• Restore the page: If accidentally deleted

For External Broken Links #

• Find archived version: Check Internet Archive (archive.org)
• Find replacement: Link to updated or similar source
• Remove the link: If no suitable replacement
• Update the citation: Replace with better source

Preventing Broken Links #

• Use redirects when moving content: Never delete without redirecting
• Keep URL structures stable: Avoid unnecessary URL changes
• Check before publishing: Verify all links in new content
• Monitor external sources: Key citations may disappear
• Use relative URLs internally: Survives domain changes

Creating a Good 404 Page #

Some 404s are unavoidable. A good 404 page mitigates the damage:

• Helpful messaging: Explain the page wasn't found
• Navigation options: Links to homepage, popular pages
• Search box: Let users find what they wanted
• Related content: Suggest alternatives
• Contact option: Way to report the broken link

Summary #

Broken link management:

• Regular audits: Monthly or quarterly link checks
• Fix internal links: Update, redirect, or remove
• Fix external links: Find replacements or archive versions
