Short answer
A broken link checker helps find links that may lead to 404 pages, server errors, empty anchors, or placeholder URLs so you can fix them before users and crawlers hit dead ends.
- Best fit: checking pasted HTML, URL lists, and crawler exports
- Outperformance angle: browser-only link QA without needing a paid crawl account for small batches

Broken link checker for pre-publish QA
Paste a draft page, crawler export, or URL status list to catch obvious link issues before a page goes live. This is especially useful for blog updates, resource lists, and tool pages with many internal links.
Works best with a crawl export
Browser tools cannot reliably fetch every live URL status because of cross-origin limits. For the most accurate batch check, paste status rows from your crawler or audit export.

Frequently Asked Questions
Can this tool crawl my whole website?▾
No. This is a browser-based checker for pasted HTML, URL lists, and crawler status rows. Use a full crawler for large sites.
What counts as a broken link?▾
Common broken link signals include 404 status codes, 5xx server errors, empty href values, and placeholder # links that users cannot actually follow.
Why do broken links matter for SEO?▾
Broken links waste crawl paths, hurt user trust, and can make important pages harder to discover when internal links point to dead URLs.
How should I fix broken internal links?▾
Update the link to the live canonical URL, restore the missing page, or redirect the old URL to the most relevant replacement.
Should external broken links be removed?▾
Replace them with a working source when possible. If the citation no longer supports the point, remove it or rewrite the section.
