Measuring GEO: The Metrics That Actually Matter
GEO is new, and most marketers are unsure what to measure. Traditional SEO metrics (rankings, organic traffic, CTR) do not directly apply. Here are the metrics that matter for AI visibility — and how to track them.
The 4 Core GEO Metrics
1. Mention Rate (40% of Visibility Score)
Definition: The percentage of relevant queries where your brand appears in AI responses.
What it tells you: How visible your brand is. A 0% mention rate means AI does not know you exist for those queries.
Target: 60%+ mention rate for brand-name queries. 30%+ for category queries.
2. Accuracy Rate (30% of Visibility Score)
Definition: The percentage of AI mentions that are factually correct about your brand.
What it tells you: Whether AI visibility helps or hurts you. Being mentioned with wrong pricing is worse than not being mentioned.
Target: 90%+ accuracy across all platforms.
3. Sentiment Score (15% of Visibility Score)
Definition: Whether AI describes your brand positively, neutrally, or negatively.
What it tells you: How AI perceives your brand quality and reputation.
Target: Positive or neutral. Negative sentiment requires immediate investigation.
4. Citation Rate (15% of Visibility Score)
Definition: The percentage of AI mentions that include a link back to your domain.
What it tells you: Whether AI visibility drives traffic. Mentions without links are brand awareness; mentions with links drive visits.
Target: 40%+ citation rate on Perplexity (highest citability), 10%+ on Google AI.
How 99Visibility Calculates Your Score
Your overall visibility score is a weighted average:
- Mention Rate: 40%
- Accuracy Rate: 30%
- Sentiment Score: 15%
- Citation Rate: 15%
This is then multiplied by a coverage factor that weights platforms by market share (ChatGPT 40%, Google AI 30%, Perplexity 20%, Claude 10%).
What Scores Mean
| Score | Status | Action |
|---|---|---|
| 0-30 | Invisible | Start with access: robots.txt, CDN reachability, server-rendered facts |
| 31-50 | Barely visible | Fix accuracy issues, strengthen brand entity |
| 51-70 | Partially visible | Optimize content structure, build authority |
| 71-85 | Well positioned | Fine-tune platform-specific strategies |
| 86-100 | AI-ready | Maintain and monitor for changes |
Frequently Asked Questions
How often should I measure GEO metrics?
Weekly for active optimization campaigns. Monthly for maintenance. AI responses change frequently — weekly monitoring catches regressions early.
Is a low citation rate bad?
Not necessarily. ChatGPT and Claude rarely cite sources inline, so citation rate is naturally lower on those platforms. Focus on Perplexity and Google AI for citation optimization.
