Domain Authority Checker – DA Checker – Check Domain Authority

Moz Domain Authority, Page Authority, Total Backlinks, Linking Root Domains, and Spam Score come from the real Moz Links API once configured. Semrush Authority Score and DoFollow/NoFollow counts come from the real Semrush Backlinks API v4 once SEMRUSH_API_KEY is set. Trust Flow comes from the real Majestic API once MAJESTIC_API_KEY is set — it replaces the old "Moz Trust" metric, which Moz itself discontinued. On-Page SEO Score and Domain Age are always real (no third-party key needed) — computed live from the site's actual HTML and a WHOIS lookup. Any field not yet configured shows "Not connected" rather than a made-up number.
