Definition. The discipline of shaping content and technical delivery so that generative search systems (ChatGPT Search, Perplexity, Google AI Overviews, Gemini) cite it correctly and use it in answers. GEO extends classic SEO with aspects such as source verification, entity consolidation, answer atomicity and retrieval friendliness.

Why it matters. The share of classic SERP clicks is falling while AI-mediated visibility is growing. For mid-sized brands this means visibility has to happen in answers, not only on search result pages.
