# What is generative engine optimization?

Where SEO competes for a position in a list of links, GEO competes to be one of the few sources an engine quotes. --- Someone asks an assistant which tool they should buy. One answer comes back. It names two or three brands and links a handful of sources. Everyone else in that category may as well not exist. That is the problem generative engine optimization tries to solve, and it is a genuinely different problem from ranking. ## What does generative engine optimization actually mean? Generative engine optimization is the practice of shaping content so that AI-generated answers name and cite your brand. The term comes from a 2024 paper by Aggarwal and colleagues, which studied how altering the content of a source page changes whether a generative engine uses it, and found that adding citations, quotations and statistics measurably increased how often a source was surfaced in an answer ([GEO: Generative Engine Optimization](https://arxiv.org/abs/2311.09735)). **GEO competes for inclusion in an answer, not for a position in a list.** That single difference drives everything else about how the work is done. The consumer changed. Classic search optimization writes for a human scanning ten blue links, who will click one. Generative engines assemble a single answer from a handful of retrieved sources, and the reader frequently never clicks anything. ## How is GEO different from SEO? The short version: same content, second audience, different win condition. | | SEO | GEO | |---|---|---| | Who consumes it | A person scanning links | A model assembling one answer | | Win condition | Rank in the top three | Get named and cited in the answer | | What it rewards | Keywords, links, dwell time | Clear claims, citable numbers, quotable sentences, structure | | Where you are read | Google's index | Bing's index, Google's index, live retrieval, and third-party sources the model already trusts | | How you lose | Page two | Not being in the retrieval set at all | The important row is the last one. On Google, being fourth is a bad day. In a generated answer, being fourth is identical to not existing, because the answer usually names three sources and stops. **The content that wins GEO is a superset of the content that wins SEO, which is why you should never write two versions of a page.** If a tactic helps one and hurts the other, the tactic is wrong. ## Where do generative engines actually read you? Not only on your own site, and this is the part most teams miss. An assistant answering a question draws on several places at once: its training data, a live web search at answer time, and whatever sources its retrieval layer already trusts. ChatGPT's search feature browses the web to answer current questions and cites the pages it used ([OpenAI: Introducing ChatGPT search](https://openai.com/index/introducing-chatgpt-search/)). Google documents a similar split, where AI features draw on its regular index and follow the same crawling rules as the rest of Search ([Google Search Central: AI features and your website](https://developers.google.com/search/docs/appearance/ai-features)). So the surface you are optimizing includes places you do not own. A well-regarded forum thread, a comparison listicle on somebody else's domain, a documentation page, a video with a transcript. **Half of generative engine optimization happens off your own domain**, which makes it closer to public relations than to technical SEO. ## What has to be true before any of this works? Three things, in order, and none of them are optional. 1. **The engines must be allowed to fetch you.** Google publishes the list of its crawlers and fetchers, including the ones tied to AI features ([Google Search Central: Overview of Google crawlers and fetchers](https://developers.google.com/search/docs/crawling-indexing/overview-google-crawlers)). If your robots file blocks GPTBot, ClaudeBot, PerplexityBot or Google-Extended, you have opted out of being cited by those systems. Plenty of sites did this without deciding to. 2. **The answer must survive extraction.** An engine lifts a span of text, not a page. A paragraph that opens with "as mentioned above" or an unattached "it" is unusable, so it gets skipped in favour of a competitor's cleaner one. Every section should open with a sentence that still makes sense alone. 3. **The claims must be checkable.** The GEO paper found that adding citations and statistics to a source raised its visibility in generated answers. That only works with real numbers attached to real sources. A fabricated figure is worse than no figure, because it is the thing a careful buyer checks first. ## How do you measure whether it is working? You cannot read a ranking, because there is no ranking. So you measure a share. Fix a set of real buyer questions, run them through each engine on a schedule, and record two things per question: were you named, and were you cited with a link. The number that matters is what fraction of the set you appear in, tracked over time. **A share-of-answer number is only meaningful against a fixed question set, measured repeatedly.** Change the questions and you have changed the ruler. That measurement is also the only honest report available in this discipline right now. Traffic will not tell you: the whole point of a generated answer is that the reader often does not visit. Rankings will not tell you either. ## Where should you start? Start where the retrieval set is thin, not where the volume is. In English, the questions with real search volume are answered by publishers with a decade of authority behind them, and the engines already trust those sources. The openings are the questions nobody has written the good answer to yet: narrow intersections, specific problems, and above all other languages, where there is far less competent material for a model to draw on. At Brictale we publish 500 or more posts a month with images through our own pipeline, and we point almost all of it at exactly those thin cells rather than at the crowded head terms. If you want to see which questions your brand is currently missing from, our visibility audit is free and you keep the result.
