What is the Neural Visibility Score (NVS)?

The Neural Visibility Score (NVS) is a proprietary 0-100 composite metric developed by VECTORY that quantifies how visible a brand is across AI answer engines including ChatGPT, Gemini, and Perplexity. It combines Share of Voice (SOV), Citation Gap analysis (GAP), Semantic Similarity (SIM), and entity recognition scores into a single actionable number.

What is a good NVS score?

An NVS score above 80 indicates strong AI visibility. Scores between 60-80 suggest moderate presence with room for improvement. Scores below 60 indicate significant AI visibility gaps. VECTORY's average client score after optimization is 94/100.

How is NVS different from Google PageRank?

Google PageRank measures a page's importance based on backlinks and is used for SERP ranking. NVS measures how frequently and accurately AI models cite, recommend, and reference a brand. They measure fundamentally different things: PageRank measures link authority while NVS measures AI citation probability.

Neural Visibility Score (NVS): How to Measure Your AI Search Presence

By VECTORY Research• March 12, 2026•7 min read

Neural Visibility Score (NVS) is a 0-100 composite metric that quantifies how visible your brand is across AI answer engines — ChatGPT, Gemini, Perplexity, and Claude. It's the AI equivalent of Google PageRank: a single number that tells you whether AI models know about you, understand you, and recommend you.

Why Traditional Analytics Don't Work for AI

Google Analytics tracks clicks, pageviews, and bounce rates. But when an AI cites your brand to a user, no click happens. The user gets the answer directly from the AI, acts on the recommendation, and your analytics show nothing. You're either being recommended or you're not — and without NVS, you have no way to know which.

The Four Components of NVS

NVS is a weighted composite of four sub-metrics, each measuring a different dimension of AI visibility:

1. Share of Voice (SOV) — Weight: 35%

What it measures: The percentage of AI-generated responses that cite or reference your brand for a given keyword cluster. If 100 AI queries about "best CRM software" mention your brand 30 times, your SOV is 30%.

How to improve it: Increase the factual density and entity clarity of your content. Deploy comprehensive Schema.org markup. Create AI Magnet Pages targeting your key keyword clusters.

2. Citation Gap (GAP) — Weight: 25%

What it measures: The differential between your citation rate and the top competitor's for the same keywords. A GAP of -15 means your top competitor is cited 15 percentage points more often than you.

How to improve it: Analyze competitor content that AI models prefer. Identify their structural advantages (better Schema.org, more specific claims, more recent data) and deploy counter-content.

3. Semantic Similarity (SIM) — Weight: 25%

What it measures: The cosine similarity between your content and the AI's response text. High SIM means the AI is closely paraphrasing or quoting your content. Low SIM means it's deriving information from other sources.

How to improve it: Write content that directly answers common queries in your niche. Use entity-first language that AI models can extract verbatim.

4. Entity Recognition (ENT) — Weight: 15%

What it measures: Whether AI models correctly identify your brand, products, and differentiators when asked directly. "Tell me about [Your Brand]" — does the AI get it right?

How to improve it: Deploy comprehensive llms.txt manifests and Schema.org Organization markup. Ensure consistent brand identity across all web properties.

The NVS Formula

NVS = (SOV × 0.35) + (GAP_normalized × 0.25) + (SIM × 0.25) + (ENT × 0.15)

Where:
  SOV = Share of Voice (0-100 scale)
  GAP_normalized = 100 - abs(GAP) capped at 0
  SIM = Semantic Similarity (0-100, from cosine similarity)
  ENT = Entity Recognition accuracy (0-100)

NVS Benchmarks

NVS Range	Classification	What It Means
90-100	Dominant	AI models consistently cite and recommend your brand
80-89	Strong	High AI visibility with minor gaps to address
60-79	Moderate	Inconsistent AI presence; competitors likely outperforming
0-59	Invisible	AI models don't know you exist or cite competitors exclusively

VECTORY's average client NVS after 30 days of optimization: 94/100.
