The SiteNexis Intelligence Index: One Number for Machine Trust Readiness

The AI Visibility Score and SII are separate SiteNexis-derived diagnostics. The SII combines six top-level dimensions and should not be read as proof that Google or another provider trusts, retrieves, or recommends a domain.

The Six SII Dimensions

• SEO Readability × 20% — technical crawlability and SEO health
• AI Visibility × 25% — derived from machine readability and semantic trust
• Semantic Structure × 20% — derived from schema completeness and machine readability
• Entity Clarity × 15% — entity confidence, consistency, and disambiguation
• Retrieval Friendliness × 10% — retrieval-readiness and query-answer alignment
• Citation Potential × 10% — factual density and authority signals

AI Visibility currently carries the largest top-level weight at 25%. AI Visibility and Semantic Structure are hierarchical dimensions that reuse lower-level inputs by design. Missing dimensions are excluded from the weighted average and reduce confidence.

SII vs. AI Visibility Score: When to Use Which

Use the AI Visibility Score to diagnose technical extraction and entity problems — the kind of issues that can be fixed in a single sprint with schema changes, content restructuring, and entity consistency work. Use the SII to track strategic trust health over time — it requires multiple audits to show meaningful velocity, and improvements come from sustained content quality, external validation growth, and contradiction resolution rather than one-time technical fixes.

What a High SII Looks Like

A higher SII reflects the current combination of available dimensions in the SiteNexis model. Interpret the breakdown, confidence, critical gaps, and recommendations alongside the composite rather than treating a score threshold as independent validation.
