On-page SEO
Broken links
Why it matters
Links that lead to errors frustrate visitors, waste crawl activity and leak the value that links pass between pages.
How to fix it
- Update or remove links that return 404 or 5xx errors.
- Add 301 redirects for pages that moved.
- Re-check links regularly, especially after deleting pages.
Check it with
- Broken Link Checker – Test every link on a page and find 404s, server errors and redirects.
- Full Site Audit (Crawler) – Crawl a whole website to find broken pages, duplicate titles, missing tags and thin content.
Scoring: a passed check earns its full weight, a warning half and an error none. How the SEO score works
