Link ML Validator

This tool validates URL health and SEO relevance for ML deployments and serverless apps hosted on platforms like Vercel. It targets ML engineers, data engineers, site reliability engineers, and SEO analysts who need reliable links across staging and production. It is used during pre-deploy checks, CI workflows, and QA audits to identify broken links, invalid redirects, misconfigured headers, or missing canonical signals before rollout.
The tool accepts one URL or a batch of URLs and evaluates HTTP(S) responses, redirect chains, latency, and content-type. Required features: live fetch, status tracing, structured report, and a health verdict. Optional/advanced features: batch processing, region-specific checks, timeout tuning, user-agent customization, and checks for canonical tags, robots.txt, sitemap availability, and header compliance.
The tool uses HTTP GET with configurable timeout, records redirect chain, computes total and per-hop latency, and classifies health using thresholds. It checks for canonical tags when HTML, validates robots.txt and sitemap if present, and surfaces detected anomalies. It handles invalid URLs, DNS failures, certificate errors, rate limiting, and timeouts, returning standardized error codes and empty fields when data is unavailable. It aligns with RFCs for URLs and HTTP semantics, using UTC timestamps and en-US assumptions unless localization is enabled. Assumes public network access and excludes security auditing or authentication-protected pages unless explicitly configured.
