GEO — definition
What is GEO? Visibility in ChatGPT and AI search, explained
GEO is not a trick or hidden markup. It is the work that makes your business findable, understandable and worth citing in generated answers.
Short answer
GEO (Generative Engine Optimization) is the work of improving how a business is discovered, understood and represented in AI-assisted search experiences: ChatGPT, Gemini, Copilot, Google's AI features. It builds on SEO, which remains the technical and editorial foundation.
How an AI assistant "finds" a business
When a question needs current information, most assistants run one or more web searches, read the pages they find, then write an answer that cites some sources. OpenAI notes, for example, that ChatGPT search sometimes rewrites a question into more targeted queries sent to search partners.
Practical consequence: to be cited, you first need to be findable and readable. A poorly indexed site, or one that blocks crawlers, starts at a disadvantage no matter how good its content is.
What GEO adds to SEO
Google Search Central states that SEO best practices apply to its generative AI features and that no special optimization is required to appear in them. GEO therefore does not replace SEO; it adds questions.
- Can assistants' crawlers (e.g. OAI-SearchBot) access your pages?
- Do your pages contain definitions and answers that are easy to extract?
- Is your business described the same way on your site and elsewhere?
- Do other credible sources corroborate what you claim?
What doesn't work
No hidden markup guarantees a citation. Structured data helps describe facts, provided it reflects visible content. An llms.txt file can serve as a discovery aid, but it is not a documented requirement or ranking lever.
Be wary of promises of "placement in ChatGPT." No one controls an assistant's answers, which vary with phrasing, context and timing.
What can be measured—and what can't yet
Platforms don't all expose the same level of measurement. Bing Webmaster Tools offers an AI Performance report (citations, cited pages, grounding queries). Traffic from ChatGPT carries utm_source=chatgpt.com in your analytics. Beyond that, testing representative questions gives dated observations, not rankings.
