Authority and safety snapshot

Authority and safety signals are useful with limits

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 94/100ClearCoverage shown; confidence not calibrated

Authority basis: Developing profile signal; AI-enriched current website profile; crawler quality is 80/100. Current model authority score is 94/100 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 · 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.
