AI Search / GEO Optimization (February 2026)
When to Use
- Use when improving visibility in AI Overviews, ChatGPT, Perplexity, or similar AI search systems.
- Use when evaluating llms.txt readiness, AI crawler access, or citation-oriented content structure.
- Use when the user asks about GEO, AI SEO, LLM visibility, or AI citations.
Key Statistics
| Metric | Value | Source | |--------|-------|--------| | AI Overviews reach | 1.5 billion users/month across 200+ countries | Google | | AI Overviews query coverage | 50%+ of all queries | Industry data | | AI-referred sessions growth | 527% (Jan-May 2025) | SparkToro | | ChatGPT weekly active users | 900 million | OpenAI | | Perplexity monthly queries | 500+ million | Perplexity |
Critical Insight: Brand Mentions > Backlinks
Brand mentions correlate 3x more strongly with AI visibility than backlinks. (Ahrefs December 2025 study of 75,000 brands)
| Signal | Correlation with AI Citations | |--------|------------------------------| | YouTube mentions | ~0.737 (strongest) | | Reddit mentions | High | | Wikipedia presence | High | | LinkedIn presence | Moderate | | Domain Rating (backlinks) | ~0.266 (weak) |
Only 11% of domains are cited by both ChatGPT and Google AI Overviews for the same query, so platform-specific optimization is essential.
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
AI Crawler Detection
Check robots.txt for these AI crawlers:
| Crawler | Owner | Purpose | |---------|-------|---------| | GPTBot | OpenAI | ChatGPT web search | | OAI-SearchBot | OpenAI | OpenAI search features | | ChatGPT-User | OpenAI | ChatGPT browsing | | ClaudeBot | Anthropic | Claude web features | | PerplexityBot | Perplexity | Perplexity AI search | | CCBot | Common Crawl | Training data (often blocked) | | anthropic-ai | Anthropic | Claude training | | Bytespider | ByteDance | TikTok/Douyin AI | | cohere-ai | Cohere | Cohere models |
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.
