Generative Engine Optimization (GEO) is the process of optimizing your website and content so that AI-powered search engines — such as ChatGPT, Perplexity, Google AI Overviews (SGE), and Gemini — can discover, understand, cite, and recommend your content to users.
Unlike traditional SEO which focuses on ranking in search result pages, GEO focuses on being included in AI-generated answers. This requires a different approach to content structure, authority signals, and technical implementation.
Key differences from traditional SEO:
- AI engines synthesize answers rather than listing links
- Citation and source attribution become the primary visibility metric
- Structured data and machine-readable content are critical
- E-E-A-T signals are weighted more heavily in AI citation decisions
