Broken external link (4xx/5xx) — the fix
This page contains a link to an external domain that returns a 4xx or 5xx HTTP status code. The external resource is no longer available.
Where this fits: internal linking in SEO
Internal links are how authority and discoverability flow through your site. They tell crawlers which pages exist, tell ranking systems which pages you consider important, and give users paths deeper into your content. Orphan pages (no internal links pointing to them) are nearly invisible to search engines regardless of quality. A deliberate internal-linking structure is one of the highest-leverage, fully-in-your-control SEO instruments.
Why broken external link (4xx/5xx) hurts your rankings
Broken external links hurt user experience and may signal to search engines that the page is not well-maintained. While linking to relevant external resources can boost perceived quality, linking to dead pages has the opposite effect. Google's quality rater guidelines specifically look for broken links as a sign of low-quality pages.
This is a medium-severity issue: individually modest, but it compounds — dozens of medium issues across hundreds of pages add up to a real quality deficit in how search engines assess the site.
How to fix it
Find an updated URL for the external resource (check the Wayback Machine for archived versions), replace the link with a similar working resource, or remove the link if no suitable alternative exists. Consider using a link monitoring tool to catch external link rot early.
Internal linking best practices
- Link every new page from at least two existing relevant pages the day it ships.
- Use descriptive anchor text — 'pricing for agencies', never 'click here'.
- Fix broken internal links weekly; every 404 wastes both crawl budget and user trust.
- Build hub pages for your main topics and spoke out to detail pages.
- Keep orphan-page count at zero — if nothing links to it, neither will Google.
