Generative Engine Optimization is the practice of structuring and positioning content so that large language model-powered search engines — such as Google AI Overviews, Perplexity, and ChatGPT — select it as a source when generating answers. GEO strategies include writing in clear, direct language, establishing topical authority through comprehensive content, using structured data, and ensuring content is easily parsable by AI systems. GEO is one of the fastest-growing areas of search optimization in 2025–2026.
