Optimizing for AI engines that generate answers (ChatGPT, Gemini, Perplexity, AI Overviews) rather than retrieval-only search engines.
Generative Engine Optimization (GEO) is a near-synonym of AEO that emphasizes the generative nature of modern AI search. While traditional search retrieves and ranks documents, generative engines synthesize answers from many sources. GEO tactics focus on becoming one of the cited sources in those synthesized answers. Search volume for the term 'generative engine optimization' is approximately 2,000 per month per Semrush as of early 2026.
Generative engines determine which brands get cited and which don't. The decision happens during synthesis, not retrieval — meaning traditional SEO ranking signals are necessary but not sufficient. GEO is how you stay in the answer.
Perplexity synthesizes an answer to 'best CRM for startups' from 15 source documents. The answer cites 4 of them. GEO is the practice of being one of the 4 cited sources, not merely one of the 15 sources crawled.
