Link Validator

The online link validator provides automated assessment of URL health for SEO teams, content managers, and webmasters. It focuses on reachability, redirects, and server responses rather than content parsing, delivering actionable results for large-scale audits. The tool supports single and batch URL checks to fit both quick verifications and site-wide crawls.
Its core workflow validates each URL by performing HTTP requests, optionally verifying TLS, and following redirects up to a configured limit. The output includes final_url, status_code, redirects, reachable, and time_taken, enabling downstream dashboards and QA processes. Results are categorized as healthy (2xx), redirected (3xx), or broken (4xx/5xx). The system prefers HEAD first to minimize data transfer, but falls back to GET when HEAD is blocked, ensuring robust validation across diverse servers. This combination yields precise, reproducible health metrics suitable for prioritizing fixes and measuring crawlability improvements.
Unique value lies in batch capability, deterministic error handling, and easily exportable reports that integrate with CI pipelines, site crawlers, and content workflows. It does not fetch private resources and does not parse page content beyond HTTP semantics, keeping checks fast and scalable for large inventories of URLs. Typical use cases include post-migration link verification, sitemap health checks, and external link profiling for SEO.
