Broken links are hyperlinks pointing to non-existent or inaccessible pages. Common types: 404 (not found), 500 (server error), expired domains. They hurt user experience and SEO rankings.
Enter a webpage URL or paste HTML code, then click Check Links. The tool extracts all links and tests each one's HTTP status—green for OK, red for broken.
Search engine crawlers waste crawl budget on broken links, lowering your site's overall score. Many broken links signal poor site maintenance, hurting rankings. Regular checks are recommended.
Due to browser CORS policies, some links can't be directly tested. The tool uses no-cors mode for rapid probing and shows status codes for accessible links. We recommend batches under 100 links.
