FastSiteCheck

About

Fast Site Check is a free SEO audit and website health checker that scans any publicly accessible URL and generates a detailed report of issues affecting search visibility. It analyzes on-page SEO elements such as title tags, meta descriptions, heading structure, canonical tags, and meta robots directives. It also runs technical checks including HTTP status and redirects, HTTPS, robots.txt and sitemap discovery, redirect chains, structured data validation, and viewport/mobile readiness signals. The tool reviews performance indicators like server response time, page size, render-blocking resources, and external scripts, plus image optimization checks such as missing alt text and missing dimensions that can impact layout shift. Link health checks include internal/external link tracking and broken link detection. Users can crawl entire sites via XML sitemaps (including nested/gzipped sitemaps) up to 10,000 URLs, view audit history, score pages, and export results as JSON or CSV for sharing or tracking fixes over time.
