What GEO Actually Measures

Unlike SEO (keyword rankings, backlinks, CTR), GEO tools track:

• Citation rate — How often you’re cited in AI answers
• Share of voice — Your citations vs competitors in your space
• Answer presence — Are you mentioned at all for target queries?
• Sentiment — How you’re characterized by the AI
• Sources used — Which of your pages AI models prefer
• Query taxonomy — Which prompt types surface your brand

GEO Tactics Worth Knowing (April 2026)

Beyond tools, these are the tactics that actually move citations in 2026:

1. Answer-first content structure — Put the direct answer in the first 50 words
2. FAQ schema (JSON-LD) — Rich data AI engines extract easily
3. Clean H2 hierarchy — AI models chunk content by headings
4. Stats and data tables — AI loves citing specific numbers
5. Freshness signals — Dated content (“As of April 2026”) cites 2× more often
6. Get mentioned in Reddit / HN — AI engines weight these heavily
7. llms.txt file — An emerging standard; adds AI-friendly site summary
8. Wikipedia presence — Still disproportionately cited by AI models
