The 15 Essential GEO KPIs
Visibility Metrics
1. Prompt Coverage Rate
Definition: Percentage of relevant user prompts where your brand appears in AI-generated responses.
Calculation:
(Prompts where brand appears ÷ Total relevant prompts tracked) × 100
Why It Matters: Prompt coverage is the foundational GEO metric. It measures your baseline visibility across AI search engines. Low coverage indicates gaps in content strategy or missing topics that AI engines consider relevant to your domain.
Benchmark:
- Excellent: 80%+
- Good: 60-79%
- Average: 40-59%
- Poor: Below 40%
Implementation: Track 100-200 relevant prompts weekly using Texta's prompt coverage monitoring. Categorize prompts by topic, intent, and difficulty to identify coverage gaps.
2. Citation Frequency
Definition: Average number of times your brand is cited per AI response where it appears.
Calculation:
(Total citations ÷ Total AI responses containing brand citations)
Why It Matters: AI engines often cite multiple sources within a single response. Higher citation frequency indicates strong topical authority and trustworthiness. This metric helps you understand how deeply integrated your content is within AI knowledge bases.
Benchmark:
- Excellent: 2.5+ citations per response
- Good: 1.5-2.4 citations
- Average: 1.0-1.4 citations
- Poor: Below 1.0
Note: Quality matters more than quantity. Ensure citations appear in contextually appropriate sections of AI responses.
3. Source Position Weight
Definition: Average position of your brand's citations within AI responses, weighted by importance (primary answer vs. supporting detail).
Calculation:
Σ(Position Score × Citation Weight) ÷ Total Citations
Where Position Score = 10 (first citation) to 1 (last citation), and Citation Weight = 2.0 (primary source) to 1.0 (supporting source).
Why It Matters: Position significantly impacts visibility and trust. Citations appearing in primary answer sections receive more attention from users than those buried in supplementary details.
Benchmark:
- Excellent: 8.5+
- Good: 6.5-8.4
- Average: 4.5-6.4
- Poor: Below 4.5
Tracking Tip: Use Texta's source position analysis to understand where your citations appear in AI responses and optimize content structure accordingly.
