What is Generative Engine Optimization (GEO)?
The discipline of increasing a brand's visibility inside AI-generated answers — the successor field to SEO for the AI search era.
Definition
Generative engine optimization (GEO) is the discipline of increasing how often and how favorably AI systems mention and cite your brand. The term comes from the 2023 Princeton/Georgia Tech paper “GEO: Generative Engine Optimization” (peer-reviewed at KDD 2024), which tested 10,000 queries and showed that content changes — adding statistics, quotations, and citations — measurably increased a source's visibility in generated answers.
GEO spans three layers: technical access (AI crawlers can fetch and parse you), content (answer-shaped, data-rich, quotable), and off-site corroboration (reviews, trade press, communities echoing your claims).
Why it matters
The buying journey is moving upstream into assistants: half of B2B software buyers now start research in AI chatbots (G2, 2026), and 69% changed vendor choice based on AI guidance. Meanwhile only ~10% of what ChatGPT cites overlaps Google's top-10 — meaning SEO success doesn't transfer automatically. GEO is how brands compete for the three-to-four mention slots each AI answer offers.
Frequently asked
Is GEO replacing SEO?
No — it sits on top of it. AI retrieval leans on search indexes, so crawlability and relevance still matter. What changes is the finish line: from ranking on a page to being mentioned in an answer, and from tracking keywords to tracking prompts.
How do I measure GEO success?
Track a defined set of buyer prompts across assistants over time: mention rate, citation rate, position, sentiment, and share of voice versus competitors. That's the metric layer platforms like Seeqly automate.
