The AI Visibility Index (AVI) is a proprietary composite metric that quantifies a brand's presence in AI-generated responses. Unlike traditional SEO metrics like Domain Authority that measure search potential, AVI measures actual AI citation performance across all major AI platforms.
AVI Score Interpretation
| Score Range | Level | What It Means | Action |
|---|---|---|---|
| 80–100 | Dominant | Brand is consistently cited across platforms | Defend position, monitor competitors |
| 60–79 | Strong | Regular citations, good visibility | Optimize weak platforms, expand prompts |
| 30–59 | Moderate | Inconsistent presence, gaps exist | Focused content + source diversity push |
| 0–29 | Emerging | Largely invisible to AI search | Foundational GEO strategy needed |
How AVI Is Calculated
AVI is a weighted composite of five dimensions:
| Component | Weight | What It Captures |
|---|---|---|
| Citation Rate | 35% | % of tracked prompts where brand is cited |
| Mention Share | 20% | Share of all brand mentions in AI responses |
| Sentiment | 15% | Positive vs. negative portrayal |
| Coverage | 15% | Consistency across ChatGPT, Gemini, Perplexity, Claude |
| Position Quality | 15% | Where brand appears (1st citation > last) |
Just as SEO professionals track rankings, GEO professionals use AVI to measure progress, benchmark against competitors via Citation SOV, and justify investment in AI optimization.
Citation vs Mention vs Visibility
| Concept | Definition | Metric | Traffic Impact |
|---|---|---|---|
| Citation | AI includes a URL link to your source | Citation Rate | Direct: clickable |
| Mention | AI names your brand in text (no URL) | Mention Rate | Indirect: awareness only |
| Visibility | Citation OR mention (union) | Brand Visibility | Combined: the top-level GEO KPI |
Brand Visibility is the union of both: any AI response run where your brand is either cited OR mentioned counts toward your visibility score. This is the top-level GEO KPI captured by AVI.
