Honest domain strength signals
Metrics like Moz Domain Authority, Ahrefs Domain Rating and Semrush Authority Score are private numbers calculated from each company's own link index; Google doesn't use any of them, and any free tool claiming to show them exactly is estimating or copying. This checker shows signals you can verify instead.
You'll see the domain's Tranco popularity rank (a research-grade ranking of the world's top million sites), its age and registration length from the registry, and whether it uses HTTPS, HSTS and declares a sitemap — the basics of a well-run, trustworthy site.
