In short
Generative engine optimisation (GEO) is the practice of structuring content and building authority so that AI systems such as ChatGPT, Perplexity, Gemini and Google AI Overviews cite or recommend your business in their answers. SEO aims to rank pages in search results; GEO aims to be part of the answer itself.
For two decades, getting found online meant ranking on Google. That is still important, but it is no longer the whole picture. Buyers increasingly ask AI assistants for recommendations, explanations and comparisons, and those assistants answer directly, often citing only a handful of sources.
Generative engine optimisation is the discipline of becoming one of those sources.
GEO, SEO and AEO compared
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank pages in search results | Be the direct answer | Be cited in AI-generated answers |
| Main platforms | Google, Bing | Featured snippets, voice assistants | ChatGPT, Perplexity, Gemini, Claude, AI Overviews |
| Success measure | Rankings, traffic | Snippet and answer wins | Citations and brand mentions in AI answers |
| Key tactics | Technical health, keywords, links | Question-led content, concise answers | Answer-first structure, schema, authority, third-party mentions |
How AI systems choose what to cite
AI assistants that search the web typically retrieve a set of relevant pages, extract the most useful passages and synthesise an answer. Several factors make a page more likely to be used.
Clear, extractable answers. Content that answers a question directly near the top of a section is easier to quote than content that buries the answer in background.
Structure. Descriptive headings, lists and tables make it easy for systems to locate and extract specific facts.
Authority and trust. Pages from recognised, well-referenced sources, and brands mentioned consistently across credible third-party sites, are more likely to be trusted.
Specificity. Concrete facts, definitions and named sources are more useful to an AI system than vague marketing language.
Accessibility. If AI crawlers are blocked or pages are hard to render, the content cannot be used.
Practical GEO techniques
Lead with the answer
Start each page, and each major section, with a concise answer of two or three sentences. Then expand with detail, examples and evidence.
Write for questions, not just keywords
People ask AI assistants full questions. Structure content around the real questions your buyers ask, using those questions as headings.
Use structured data
Schema markup such as Organization, Article and FAQPage helps machines understand what a page is about and who published it.
Be consistent about who you are
Use the same company name, description and service terms across your website, profiles and directories. Consistency helps AI systems connect information about your brand.
Earn mentions elsewhere
AI systems draw on many sources beyond your website, including reviews, industry publications, forums and directories. Being discussed credibly elsewhere strengthens your visibility.
Remove the fluff
Promotional superlatives add nothing an AI system can use. Replace "industry-leading solutions" with specific statements about what you do, for whom and how.
How to measure GEO
GEO measurement is still maturing. A practical approach is to build a list of the questions that matter most to your business, run them through the main AI assistants regularly, and record which brands and pages are cited. Track changes over time alongside traditional rankings and organic enquiries.
Should your business invest in GEO?
If your buyers research before they buy, they are increasingly doing part of that research through AI. The businesses that structure their content and authority for AI systems now will be the ones those systems recommend. Because GEO builds on good SEO practice, the investment also strengthens your traditional search visibility.
Our SEO and AI Search Visibility service combines both. For a step-by-step approach, see how to get your business recommended by ChatGPT.
Frequently asked questions
Is GEO replacing SEO?
No. GEO builds on SEO. AI systems often draw on content that is already well indexed and trusted, so strong SEO foundations remain essential. GEO adds a focus on clear answers, structure and authority signals.
What is the difference between GEO and AEO?
Answer engine optimisation (AEO) usually refers to optimising for direct answers such as featured snippets and voice results. GEO refers to optimising for AI-generated answers from large language models. In practice the techniques overlap heavily.
How do I know if AI assistants mention my business?
Ask the questions your buyers would ask in ChatGPT, Perplexity, Gemini and Google, and record which brands and sources are cited. Repeat regularly, because AI answers change over time. Specialist tools can automate this tracking.
