SEO vs Generative Engine Optimization (GEO)
SEO, search engine optimisation, aims to rank web pages in traditional search results so people click through. GEO, generative engine optimisation, aims to have content cited, quoted, or summarised in answers produced by AI systems such as chat assistants and AI search features. They overlap heavily, but GEO puts more weight on clear answers, structure, and citable facts.
What SEO optimises for
Traditional SEO aims to make pages appear high in search engine results for relevant queries. It covers technical foundations, such as crawlability, speed, and structured data; content that matches what searchers need; and authority signals, such as links from other reputable sites. Success is measured in rankings, impressions, click-through rate, and organic traffic. The searcher sees a list of links and chooses which to visit.
What GEO optimises for
Generative engine optimisation aims to make content appear in answers generated by AI systems, including chat assistants and AI-generated summaries in search results. A 2023 research paper helped popularise the term. In these interfaces the user often receives a synthesised answer rather than a list of links, with a few sources cited or none at all. Success means being one of the sources the system draws from, quotes, names, or links, and being described accurately.
Where they overlap
Most of what helps SEO also helps GEO. AI systems that retrieve web content often rely on search indexes, so pages that cannot be crawled or ranked are less likely to be cited. Clear, accurate, original content from credible sources is valued by both. Structured data and well-organised headings help both search engines and AI systems understand what a page covers. Teams rarely need separate content for each; they need content that serves both.
Where GEO differs
GEO places more weight on answer-shaped content: concise definitions near the top of a page, direct answers to specific questions, comparison tables, step-by-step explanations, and specific facts with clear attribution. AI systems tend to extract passages that answer a question on their own, so self-contained paragraphs help. Mentions of a brand across reputable third-party sources may also influence whether AI answers name that brand, beyond links to its own pages.
Measuring performance
SEO measurement is mature, with rankings and traffic data from search consoles and analytics. GEO measurement is newer. Teams track whether their brand and pages appear in AI answers for target questions, how they are described, referral traffic from AI tools, and citation frequency over time, often using repeated sampling of prompts because AI answers vary between runs.
A practical approach
Keep strong SEO foundations, then shape content for answers: start pages with a direct, self-contained answer, use question-based headings that match how people ask, add FAQs that address follow-up questions, use tables for comparisons, cite sources for facts, and keep content current. Earn mentions in credible publications and communities in your field. Monitor how AI systems describe you, and correct inaccuracies in your own content where they originate.
What this means for partner content
Affiliate and partner content, such as reviews, comparisons, and tutorials, is often the kind of independent source AI answers draw on. Accurate partner content that links to your authoritative pages supports both SEO and GEO.

| User sees | A list of links | A synthesised answer with some sources |
| Content emphasis | Relevance, depth, authority | Direct answers, structure, citable facts |
| Main metrics | Rankings, clicks, organic traffic | Citations, mentions, AI referral traffic |
| Maturity of tools | Established | Emerging |
Frequently asked questions
- Is GEO replacing SEO?
- Not replacing, but changing it. Traditional search results still drive large amounts of traffic, and AI systems often rely on search indexes to find content. GEO adds a layer on top of SEO: shaping content so it is easy for AI systems to extract, cite, and describe accurately.
- What is the difference between GEO and AEO?
- They describe very similar goals. Answer engine optimisation, AEO, originally referred to optimising for featured snippets and voice assistants, and is now used for AI answers too. Generative engine optimisation, GEO, refers specifically to AI systems that generate answers. In practice, the tactics largely overlap.
- How do I know if AI tools cite my content?
- Test the questions your audience asks in the AI tools they use, record whether your brand or pages appear and how they are described, and repeat over time because answers vary. Check analytics for referral traffic from AI tools. Specialised monitoring tools can also automate prompt sampling across several assistants.
