9 GEO Tactics Ordered by Impact
1. Add Statistics with Source Citations (Highest Impact)
Replace vague claims with specific cited stats. "Many users use AI search" → "AI-referred sessions grew 527% YoY in 2025 (Previsible AI Traffic Report)." The attribution is what makes a claim citable.
2. Lead with Direct Answers
Open every informational page with a direct 2-3 sentence answer. AI systems extract the intro most frequently — think Featured Snippet logic.
3. Implement FAQPage Schema
30-40% higher citation rates. Add 4-7 questions with 2-4 sentence answers to every informational page.
4. Allow AI Crawlers in robots.txt
GPTBot, ClaudeBot, PerplexityBot must all be allowed. Blocked = cannot be cited.
5. Create Comparison Content
Comparison articles generate 32.5% of all AI citations. Create "[A] vs [B]" content across your topic areas.
6. Add llms.txt to Root Domain
A new standard guiding AI systems on how to understand your site. Place at yourdomain.com/llms.txt with: site description, key pages, preferred citation format.
7. Build Topic Clusters
AI systems assess topical authority. 20 interconnected articles on your topic = cited far more than one article.
8. Update dateModified Schema
AI systems prefer recent sources. Keep Article schema dateModified current.
9. Earn Off-Site Mentions
Being cited on authoritative third-party sites increases your entity authority in AI knowledge graphs.
