Domain Authority Checker — frequently asked questions
Is this Google's official Domain Authority?
No — Google does not publish a public authority metric, and Domain Authority as commonly known is a third-party score. This is a composite estimate built from live signals: HTTPS, robots.txt, XML sitemap, title and meta quality, content depth and search presence, plus optional OpenPageRank backlink data.
How should I use the score?
As a relative indicator for comparing domains and finding fixable technical gaps — not as an absolute measure. The factor breakdown is more useful than the headline number, because it shows exactly which signals are missing.
