URL Validator

This URL validator analyzes a single web address to expose syntax errors, accessibility problems, and potential redirect issues. It targets developers, site publishers, SEO practitioners, and QA teams who need quick health checks as part of content workflows, sitemap validation, or migration verification. The tool accepts a URL input and optional settings and returns a structured health profile rather than a raw HTTP dump. By focusing on the exact URL path and host, it helps ensure that linked pages conform to expected formats and can be crawled reliably.

At the core, the validator applies RFC 3986 parsing to normalize the input, enforces a consistent scheme preference (prefer https when available), and resolves a redirect chain up to a defined limit. It issues a lightweight HEAD request first and falls back to GET when necessary to infer the final destination and the HTTP status. It reports normalized URL, final URL, status code, number of redirects, and a boolean for overall validity. Optional TLS checks surface certificate or hostname problems impacting trust.

Use cases include preflight checks for sitemap generation, verification of outbound and affiliate links, auditing of migrated domains, and CI checks before publishing content. Unique differentiators include rapid, deterministic outputs suitable for automation, explicit final URL reporting, and structured warnings to guide remediation. Outputs are designed for easy integration into dashboards, crawlers, or content deployment pipelines, with guidance for SEO teams on how to interpret statuses and plan fixes. The tool emphasizes reliability, clarity, and low false positives in production workflows.
