GEO Analysis Criteria (Updated)
1. Citability Score (25%)
Optimal passage length: 134-167 words for AI citation.
Strong signals:
- Clear, quotable sentences with specific facts/statistics
- Self-contained answer blocks (can be extracted without context)
- Direct answer in first 40-60 words of section
- Claims attributed with specific sources
- Definitions following "X is..." or "X refers to..." patterns
- Unique data points not found elsewhere
Weak signals:
- Vague, general statements
- Opinion without evidence
- Buried conclusions
- No specific data points
2. Structural Readability (20%)
92% of AI Overview citations come from top-10 ranking pages, but 47% come from pages ranking below position 5 — demonstrating different selection logic.
Strong signals:
- Clean H1→H2→H3 heading hierarchy
- Question-based headings (matches query patterns)
- Short paragraphs (2-4 sentences)
- Tables for comparative data
- Ordered/unordered lists for step-by-step or multi-item content
- FAQ sections with clear Q&A format
Weak signals:
- Wall of text with no structure
- Inconsistent heading hierarchy
- No lists or tables
- Information buried in paragraphs
3. Multi-Modal Content (15%)
Content with multi-modal elements sees 156% higher selection rates.
Check for:
- Text + relevant images
- Video content (embedded or linked)
- Infographics and charts
- Interactive elements (calculators, tools)
- Structured data supporting media
4. Authority & Brand Signals (20%)
Strong signals:
- Author byline with credentials
- Publication date and last-updated date
- Citations to primary sources (studies, official docs, data)
- Organization credentials and affiliations
- Expert quotes with attribution
- Entity presence in Wikipedia, Wikidata
- Mentions on Reddit, YouTube, LinkedIn
Weak signals:
- Anonymous authorship
- No dates
- No sources cited
- No brand presence across platforms
5. Technical Accessibility (20%)
AI crawlers do NOT execute JavaScript — server-side rendering is critical.
Check for:
- Server-side rendering (SSR) vs client-only content
- AI crawler access in robots.txt
- llms.txt file presence and configuration
- RSL 1.0 licensing terms

Recommendation: Allow GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot for AI search visibility. Block CCBot and training crawlers if desired.
llms.txt Standard
The emerging llms.txt standard provides AI crawlers with structured content guidance.
Location: /llms.txt (root of domain)
Format:
# Title of site
> Brief description
## Main sections
- [Page title](url): Description
- [Another page](url): Description
## Optional: Key facts
- Fact 1
- Fact 2
Check for:
- Presence of
/llms.txt
- Structured content guidance
- Key page highlights
- Contact/authority information
RSL 1.0 (Really Simple Licensing)
New standard (December 2025) for machine-readable AI licensing terms.
Backed by: Reddit, Yahoo, Medium, Quora, Cloudflare, Akamai, Creative Commons
Check for: RSL implementation and appropriate licensing terms.
