What is GEO — the direct answer
GEO (Generative Engine Optimization) is the practice of structuring your content and managing your online presence so that generative AI systems — ChatGPT, Perplexity, Gemini, Google AI Overviews — find, trust and cite your website in their answers. Instead of competing for a blue-link position on a results page, you compete for a mention inside the answer itself, exactly where the user is reading.
The term emerged once generative AI became part of mainstream search. People increasingly ask an assistant instead of typing into a search box — and if your site is not in the assistant's answer, you effectively don't exist for that growing share of the audience. You can measure where you stand today with GeoTo.be's free AI visibility checker: it asks real customer questions to four AI platforms and shows whether they cite you.
How is GEO different from SEO and AEO?
Almost not at all — and that is the position of the search engines themselves. The field has produced a zoo of overlapping labels: AEO (Answer Engine Optimization), AIO (Artificial Intelligence Optimization), LLMO (Large Language Model Optimization), AI SEO. As of early 2026 there is no consensus definition separating these terms in the academic literature; practitioners use them interchangeably (Wikipedia: Generative engine optimization).
Where the major players stand:
- Google, in its documentation “Optimizing your website for generative AI features on Google Search”, states that optimizing for generative AI is optimizing the search experience — and therefore still SEO.
- Bing uses the term “generative engine optimization” in its own documentation, while noting that SEO fundamentals “support eligibility for AI-generated experiences”.
- Forrester Research (analyst Nikhil Lai, 2025) argues that AEO and its siblings are “significantly, but not fundamentally, different from SEO”, and that advocates of the new acronyms “tend to exaggerate the differences to carve a startup-sized hole in marketers’ tech stacks”.
The practical takeaway: if someone sells you “GEO” as a separate kind of magic on top of SEO, that is marketing, not engineering. The foundation is shared — well-structured, citable, factually dense content.
How do generative engines decide whom to cite?
LLM-based systems do not crawl the web in real time the way a classic search stack does. They retrieve, summarize and re-present information from sources they consider reliable. By early 2026, GEO practitioners report the focus has shifted from keyword placement toward semantic relevance — how well your content actually answers the question a user asked the assistant.
What that means in practice:
- Answer the question directly. The first paragraph of a page should carry the essence in two or three sentences, no warm-up. These are the fragments engines lift into answers.
- Structure for machines. Question-shaped headings, lists, tables and FAQ blocks make a page easy to quote fragment-by-fragment.
- Be citable in the first place. Generative engines favor sources that other sources already reference: industry publications, reviews, comparison pages, documentation.
- Cover real customer questions. Not abstract “keywords”, but the actual phrasing people type at an assistant: “what is X”, “best alternatives to Y”, “Z reviews and pricing”.
Which tools show whether AI cites you?
Free first steps:
- Bing Webmaster Tools — the AI Performance report;
- Google Search Console — performance reporting for Google's generative AI features.
Both cover only their own engines. ChatGPT, Perplexity and Claude are invisible there — yet those are the assistants where audiences ask questions directly. Dedicated GEO tooling monitors how a brand is cited across LLM answers; Wikipedia's overview of GEO lists the tool categories.
GeoTo.be does exactly this: it generates the questions your potential customers would ask an AI assistant about your business, asks them to four platforms, and shows you whether each one cites you — with sources.

Frequently asked questions
Are GEO and SEO different disciplines? No. Per Google's and Bing's own documentation, optimizing for generative AI is a continuation of SEO: same foundation, new surface where the answer appears.
Which term is correct — GEO or AEO? Either. There is no accepted boundary between them (as of early 2026); the industry uses them interchangeably. Pick the one your audience understands.
Can you pay to get into ChatGPT's answers? Not guaranteed. Advertising inside AI answers exists (OpenAI and Google started monetizing them), but that is adjacent to GEO — it is not “buying citations” in the organic answer.
Where should I start with GEO? With measurement. Learn whether AI assistants cite you today and which questions surface your competitors. Then work the fundamentals: direct answers, clean structure, FAQ coverage, and mentions in sources the engines already trust.
