99 factors · method v1.2.0 · independent project · methodology open
Web Quality Index is a public registry. Every website on the open web has a score between 0 and 100, computed from 99 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, or instantly via on-demand rescan.
What this is
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.
The product is the data and the methodology that produces it.
How scoring works
The full rule for each of the 99 factors — tier (Required, Recommended, or Variable), data source, pass/warn/fail threshold, and the weight each factor carries by site type — is published in the (open with the KB button in the header, ⌘/Ctrl + /, or by clicking any standard or factor name in a report). Every score is independently reproducible from those rules.
Independence
WQI’s mission is to make the web safer, faster, and more trustworthy by giving any party — site owner, customer, journalist, regulator, vendor — an inspectable, free, and consistently-applied measurement of public-web quality.
Scoring rules and factor weights are published in full, and the method version stamped at the bottom of every page keeps historical scores attributable to the rules in force when they were computed.
Corrections
We publish corrections promptly when they’re warranted. If you believe a score is wrong, write corrections@webqualityindex.com with the domain and the factor. Corrections are evaluated against the published rule, not against the requester’s identity or relationship to us.
