Authority and safety snapshot

Authority and safety signals look usable

This report combines public evidence source, live checks, freshness, and ownership status so readers can evaluate the website without treating the score as a popularity rank.

Authority 97/100Clear current signalsHigh confidence

Authority basis: Strong profile signal; Legacy AboutUs archive import; crawler quality is 87/100. Current model authority score is 97/100 from report-derived and stored evidence inputs. External evidence used: Tranco rank, Open PageRank, RDAP age, DMARC, MX. Missing external inputs: Threat feed.
Safety band: Clear current signals · Safety 90/100; Model band: Clear. No current live trust check is producing a warning in this report. New or unclaimed status is not treated as unsafe by itself, and absence of external threat-feed data is not treated as a clean bill of health.
