Generative Engine Optimization
(GEO)The practice of optimizing content and brand signals so that AI-powered search engines (ChatGPT, Perplexity, Google AI Overviews) cite, reference, and recommend your brand in generated responses. The AI-era evolution of SEO.
Generative Engine Optimization (GEO) is the practice of making your brand visible in AI-generated answers. Where SEO optimizes for search engine result pages (SERPs), GEO optimizes for the AI-generated responses that increasingly replace them.
Why GEO Matters
When someone asks ChatGPT, Perplexity, or Google's AI Overview a question, the AI synthesizes an answer from its training data and cited sources. GEO ensures your brand and content are among those sources.
Research shows that 82-89% of AI-generated answers reference third-party publications — not brand-owned content. This means earned authority is the primary lever for GEO, not on-page technical optimization.
GEO vs. SEO
| SEO | GEO |
|---|---|
| Optimize for keyword rankings | Optimize for AI citations |
| Target search result pages | Target AI-generated answers |
| Backlinks as signals | Entity authority as signals |
| On-page content | Cross-platform presence |
| Measure by rank position | Measure by citation frequency |
Key GEO Techniques
- Earned media in authoritative publications — AI engines heavily weight tier-1 sources
- Entity signal strengthening — Schema markup, Knowledge Graph, Wikipedia presence
- Citation-optimized content structure — Clear claims, statistics, expert quotes that LLMs extract
- Multi-source corroboration — The same facts appearing across multiple trusted sources
- Freshness signals — Recent, updated content is preferred by AI engines
GEO vs. AEO
GEO is the broader discipline; Answer Engine Optimization (AEO) is a subset focused specifically on answer engines like Perplexity and Google AI Overviews where a single definitive answer is surfaced. Both fall under the Machine Relations framework.
GEO in Practice
AuthorityTech pioneered GEO as a core component of Machine Relations. The AI Visibility Audit measures your current GEO performance across major AI engines — tracking share of voice and citation gaps against competitors.
