Model history
WebTrustScore model revision history
Every completed scan is stamped with the scoring-model and evidence-collection version that produced it — shown on each report as “Model X · collection Y”. This page records what each version changed. The model version moves when the scoring math, bands, or overrides change; the collection version moves when evidence gathering changes. Historical scores keep the version they were computed under and are never re-scored.
Model 3.2.0 · collection 2.0.1
No score for a domain with no site. A domain that has no operating site to trust — it redirects to a different domain, shows a parking placeholder, is listed for sale, or has no reachable site — no longer receives a number at all; the report and badge state the situation (and, for a redirect, name the destination) instead of publishing a score that would misrepresent a vacant name. This replaces the previous approach of capping such domains at 599. A redirect that stays on the same registrable domain (www → apex, a subdomain, http → https) is not a redirect for this purpose and scores normally. No signal weights, curves, or band thresholds changed — the five-signal math is unchanged for real sites.
Model 3.1.0 · collection 2.0.1
Live-site-state caps. The scan now reads what a visitor actually lands on and, when there is no operating site to evaluate — a parking placeholder, a domain listed for sale, or no reachable site at all — caps the trust score at the top of the “Concerning” band (599) and says why, so a vacant domain with clean transport and DNS can no longer read as trustworthy. A cross-domain redirect to another brand is disclosed on the report but does not change the score yet. The state (Active site / Parked / For sale / Redirects to … / No live site) is shown as an overlay beside the score. No signal weights, curves, or band thresholds changed; the five-signal math is otherwise identical.
Model 3.0.0 · collection 2.0.1 — 2026-06-12
Collection fix: an origin that cannot be contacted (the edge returns a 520–530 “origin unreachable” response instead of failing outright) is no longer counted as a reachable site with valid TLS, so unreachable or non-existent domains stop earning transport credit.
Model 3.0.0 · collection 2.0.0 — 2026-06-12
Major upgrade. Added an explicit confidence score (per signal and overall) reported separately from the trust score and shown on free scans, with a band cap when confidence is low. Added invalid-TLS (cap 699) and brand-impersonation (cap 499) overrides, multi-URL malware/phishing checks on premium, optional opt-in reputation sources (off by default), and deeper identity, email-authentication (DKIM), and consumer-transparency checks.
Model 2.1.0 · collection 1.1.0 — 2026-06-10
Collection reliability. A registry fallback for ownership lookups and a more honest handling of blocked page crawls fixed two bugs that had been understating scores. Scoring math unchanged.
Model 2.0.0 · collection 1.0.0 — 2026-05-29
First public scoring model: five weighted signals — security, ownership identity, reputation, consumer transparency, and operational resilience — combined into a 0–1000 trust score across seven bands, with critical-risk caps for confirmed malware and phishing.
