What This Report Measures

The Web Technology Index (WTI) is the infrastructure and security benchmark created by Clickerwayne Zelle Solutions Inc. It evaluates how a website is built, secured, and delivered to search crawlers and browsers. Every domain receives two independent scores:

  • WTI-Raw: 65 checks across 8 layers (Transport, Headers, Security, etc.) measuring the raw HTTP response.
  • WTI-JS: 18 checks across 4 layers measuring JavaScript dependency and progressive enhancement.

All scores are generated from a single HTTP GET. The same server response always produces the same score. Every completed audit is cryptographically signed with ES256 and stored in a public manifest that records the score, the audit date, and the SHA-256 of the exact server output.

Methodology Summary

WTI-Raw (65 checks, 100 pts): Transport (15), Response Headers (15), Crawl Foundation (12), Document Structure (18), Structured Data (10), Resource Efficiency (10), Security Posture (10), AI Discovery (10). Every check is derivable from the raw HTTP response and DOM.

WTI-JS (18 checks, 100 pts): Content Availability Pre-JS (35), Progressive Enhancement (20), Script Delivery (15), SSR and Hydration (30). Measures whether a crawler can read the page without executing JavaScript.

Signing: Each completed audit produces an ES256 signature over the score, audit date, and pages evaluated. Full rubric at /wti/methodology.
