Broken internal link
Internal links guide visitors and spread ranking signals. A link to a dead URL sends both into a wall.
What it is
This check flags hyperlinks whose target internal URL responds with an error (typically 404).
Why it matters for SEO
Broken internal links frustrate users, waste crawl budget on dead ends, and stop link equity from flowing to the right pages.
Example
<a href='/blog/ancien-article'>Read more</a> -> 404 Not Found
How to fix
- Update the link to the correct, live URL.
- If the target moved, link to the new page directly.
- If the target is gone, remove the link or replace it.
- Re-crawl to confirm no internal links resolve to errors.
