# Hybrid GEO & SEO Synthesis

## The 100-Point HSI (Hybrid Search Visibility Index)

Today's customers don't just search on Google. They also ask ChatGPT, Gemini, and Copilot to help them decide. Our HSI Index reveals the full picture: how you perform in traditional SEO and whether generative AI agents can cite your site as a source.

## The 4 Pillars: Components of the HSI Index

Each pillar is scored by one of our AI agents.

 🔍 WEIGHT: 30%

### Classic SEO (Lumina)

Assessment of traditional search (Google) performance, keyword relevance, on-page SEO quality, and backlink profile.

 ⚡ WEIGHT: 20%

### PageSpeed (Trixie)

Fast page loads and a quick TTFB (time to first byte). If your server is slow, AI crawlers may give up before reading your page.

 🧠 WEIGHT: 25%

### Structured Data (Agnes)

Implementation of JSON-LD semantic markup to deliver information to AI systems in machine-readable format.

 🚀 WEIGHT: 25%

### AI Citation Potential (Verity)
