Some internal links point to pages returning 4xx or 5xx errors, leading users and crawlers to broken destinations.

Why it matters

Internal links to broken pages waste crawl budget, dilute link equity, and frustrate users with 404 or error pages. Search engines may downgrade sites with significant dead-end navigation, harming SEO and user trust. This issue highlights which source pages need their links corrected.

Impact

Unresolved, this issue can reduce SEO performance and degrade user experience due to dead-end navigation.

How it's detected

An automated crawler checks each internal link and flags those pointing to URLs that return 4xx or 5xx HTTP status codes.

Common causes

Linked page was deleted or moved without updating links
Typographical errors in link URLs
Linked page is temporarily down or misconfigured
Incorrect case sensitivity in URLs on case-sensitive servers

How to fix it

For each broken link, either restore the missing page or set up a 301 redirect to a relevant replacement. Preferably, update the source pages to link directly to the correct, live destination. Direct links ensure full link equity and faster user experience compared to relying on redirects.

Code examples

Broken internal link (problem)

<a href="/docs/nodes/ai-agent">AI Agent Documentation</a> <!-- /docs/nodes/ai-agent returns 404 -->

Fixed by updating to correct destination

<a href="/docs/nodes/ai-agent-v2">AI Agent Documentation</a> <!-- /docs/nodes/ai-agent-v2 is live -->

Fixed by redirecting broken target (Apache .htaccess)

Redirect 301 /docs/nodes/ai-agent /docs/nodes/ai-agent-v2

FAQ

What should I do if the linked page was intentionally removed?

Update all source links to point to the most relevant existing page, or remove the links if no replacement exists.

Is it better to fix the link or set up a redirect?

Fixing the source link is best for SEO and user experience, but a 301 redirect is a good backup if you can't update all links immediately.

How often should I check for broken internal links?

Regularly audit your site for broken links, especially after content updates or site restructures.

Do 4xx and 5xx errors have the same SEO impact for internal links?

Both are negative, but 5xx errors may indicate server issues while 4xx errors usually mean the content is missing or moved.
