What Is a Broken Link Checker?
A broken link checker scans links on a webpage and identifies URLs returning error responses like 404, 410, or server failures. Broken links hurt user experience, waste crawl budget, and weaken internal link flow for SEO.
Why Broken Links Matter for SEO
- Internal broken links can block crawlers from discovering deeper pages.
- Dead outbound links reduce perceived content quality and trust.
- Large numbers of broken links can signal poor maintenance.
What This Tool Checks
- Fetches the target page and extracts crawlable links.
- Checks link status codes for internal and external URLs.
- Flags links returning 4xx/5xx or unreachable responses.
- Returns a priority-friendly summary and fix recommendations.
Best Practices
- Fix internal broken links first.
- Replace removed pages with relevant live URLs.
- Run periodic checks after content updates or migrations.
