SCS Website Health scans any website and gives you a QA-style report in seconds: broken links, missing or duplicate meta tags, SEO issues, and other problems that quietly hurt your site.
Most site checkers are built for SEO marketers. This one is built by a QA engineer, so it treats your website like software under test: clear pass/fail checks, prioritized issues, and fixes you can act on.
