About
Web Quality Index is a public registry. Every website on the open web has a score between 0 and 100, computed from 86 factors across security, performance, SEO, AI-readiness, privacy, accessibility, brand presence, and email health. Methodology is published in full and versioned. Scores update within 24 hours of a fix.
What this is, in 200 words
Most quality measurements live behind paid tools or proprietary algorithms. We think a public site’s technical, structural, and trust posture should be inspectable by anyone. WQI is the registry layer for that idea.
We measure each factor with deterministic checks against public signals: DNS records, HTTP responses, HTML structure, third-party APIs (Google PageSpeed, RDAP, Wayback Machine), and a few licensed datasets. The scoring formula is published. Everything we measure, we tell you how to fix — and we re-score when you do.
We don’t rank-bait. We don’t pay-to-promote. We don’t hide methodology behind enterprise pricing. The product is the data and the methodology that produces it.
How scoring works
Each factor is graded pass, warn, or fail based on a published rule. Factor scores roll up to category scores; category scores roll up to an overall score. Method v0.1 — 2026-04-25 uses equal-weight rollups; v0.2 will introduce category weights informed by historical correlation with site outcomes (uptime, ranking stability, breach incidence). Historical scores remain attributable to the method version under which they were computed.
Who runs it
Web Quality Index is a project of Experial Studio. Studio infrastructure is operated independently of any factor we measure. No factor weight or threshold is influenced by Studio business interests.
Disclosure
Experial Studio operates Fresh Coat, a managed-presence service that helps small businesses fix the kinds of problems WQI surfaces. Fresh Coat is one of many possible vendors; we do not give it preferential treatment in scoring or recommendations. Sites that need help fixing what we measure can use any vendor. WQI’s job is to render the measurement, not to sell the fix.
