Broken internal link (4xx/5xx) — the fix
This page contains a link to another page on the same domain that returns a 4xx or 5xx HTTP status code. The linked page is either missing or experiencing server errors.
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 internal link (4xx/5xx) hurts your rankings
Broken internal links waste crawl budget as search engines attempt to follow dead links. They dilute link equity that should flow to working pages and create poor user experience when visitors hit dead ends. A high number of broken internal links signals poor site maintenance to search engines, potentially affecting crawl frequency and overall quality assessment.
This is a high-severity issue: it directly suppresses rankings or click-through on the pages it affects. It belongs in your current sprint, prioritised by how many pages carry it.
How to fix it
Either fix the destination page so it returns a 200 status, update the link to point to a valid alternative URL, set up a 301 redirect from the broken URL to the correct destination, or remove the link entirely if no suitable replacement exists.
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.
