About External Link Checker

Enter any URL to crawl your website and map every outbound link — each external URL is checked for HTTP status, response time, redirect chains, HTTPS support and rel attributes. The checker detects broken external links (4xx/5xx), redirect chains, slow destinations, missing rel="noopener", unsafe HTTP links and duplicate outbound links. Per-link details include source page, anchor text, destination URL, status code, response time, redirect count, nofollow/follow status, target blank and all rel attributes. An overall SEO Score (0–100) surfaces every issue with specific, actionable recommendations. Export the full report as CSV, JSON, TXT or a print-ready PDF.

Frequently Asked Questions

External links (outbound links) are hyperlinks on your website that point to pages on other websites. They provide additional context and references for your readers, and when placed on high-authority pages they can signal credibility to search engines. However, broken external links damage user experience and can indicate neglect to crawlers.

External websites change URLs, remove pages or go offline without notifying you. Broken external links return 404 or 5xx errors when clicked, hurting user experience and wasting crawl budget. Redirect chains add unnecessary latency. Missing rel="noopener" on target="_blank" links is a security vulnerability. Regular audits keep your links accurate and your site healthy.

Broken external links are less harmful than broken internal links, but they still reflect poorly on site quality. Google's quality raters assess whether a page's outbound links lead to credible, live destinations. A high proportion of broken outbound links can contribute to a low-quality signal, especially combined with other issues.

Yes. For every external link the checker follows the full redirect chain and reports each hop's status code and URL. Redirect chains (A→B→C) are flagged because each extra hop adds latency and may dilute any link signals passed to the destination.
