Webmaster SEO Auditor

Purpose-built for webmasters and SEO teams, this tool analyzes a domain to produce an objective SEO health profile by combining publicly observable signals with crawl-derived data such as HTTP status codes, indexability indicators, and sitemap completeness. It validates crawlability, robots.txt accessibility, sitemap integrity, canonical tag usage, and URL structure, then aggregates findings into a domain score and per-URL issues dataset.
The scoring logic assigns weights to technical accessibility (crawlability, redirects, robots.txt), on-page signals (titles, meta descriptions, header nesting, image alt text), performance (speed and render metrics), and mobile usability. It flags high-priority items such as 404s, orphaned pages, duplicate content risks, missing metadata, slow resources, and improper structured data. Outputs include a health_score, an annotated issues list with severity and impact, and recommended fixes with concrete examples.
Target users include webmasters, SEO practitioners, marketing teams, and developers responsible for large sites or client portfolios. The tool supports migration planning, ongoing health monitoring, and reporting for leadership. Its unique differentiators are a transparent scoring model, actionable per-URL guidance, and exportable results suitable for integration with CI/CD pipelines or project management tools.
Core features include domain-level health assessment, page-level issue reporting, bulk URL checks, and export options (CSV/JSON). Use cases span pre-launch checks, post-deploy verifications, and periodic audits to maintain search visibility. The tool adheres to industry guidelines and provides localization-ready outputs while avoiding proprietary data dependencies.
