Authoritative definitions for SEO, Answer Engine Optimization, Generative Engine Optimization, and AI search terms.

SEO (Search Engine Optimization): SEO is the practice of improving a website's visibility in organic search results by aligning content, technical health, and authority signals with how search engines rank pages.
AEO (Answer Engine Optimization): AEO optimizes content so answer engines—Google AI Overviews, Perplexity, Bing Copilot—can extract concise, authoritative answers and cite your pages as sources.
GEO (Generative Engine Optimization): GEO focuses on earning citations from large language models by publishing verifiable data, clear definitions, and quotable expert statements.
AI Overviews: AI Overviews are Google's generative summaries at the top of some SERPs. They synthesize multiple sources and can reduce clicks to traditional blue-link results.
