What Is GEO in SEO: Generative Engine Optimisation Explained

The way people find information online is changing. For decades, the dominant model was a search engine returning a list of links and the user choosing which to click. That model has not disappeared, but it is increasingly being supplemented by something different — AI-generated answers that synthesise information from multiple sources and deliver a direct response at the top of the results page, or within AI tools like ChatGPT, Perplexity, and Google’s AI Overviews. Generative Engine Optimisation, commonly shortened to GEO, is the discipline of ensuring your business and content are visible within those AI-generated responses.

How GEO Differs from Traditional SEO

Traditional SEO is primarily about earning positions in a ranked list of links. The user reads the results, decides which looks most relevant, and clicks through to a website. GEO addresses a different challenge: being cited or referenced within an AI-generated answer that may not present a traditional list of links at all. If someone asks an AI assistant which Google Ads agencies in London are worth considering, or asks for an explanation of a concept that your content covers definitively, appearing in that answer is valuable in a fundamentally different way from appearing in a list of blue links.

The principles overlap with traditional SEO but the weighting of factors differs. AI systems favour content that is authoritative, clearly structured, comprehensive on its topic, and consistent across multiple sources. Entity recognition — Google and AI systems understanding that a specific business name is associated with specific expertise in a specific location — is particularly important for GEO.

Why GEO Matters in 2026

Google’s AI Overviews now appear for a significant proportion of searches, particularly informational and commercial investigation queries. Where an AI Overview appears, it sits above all traditional organic results and captures a large share of user attention. Businesses whose content is referenced in those overviews maintain visibility even as traditional click-through rates from organic results decline. Those whose content is not referenced lose visibility without necessarily understanding why their traffic is falling.

The trend extends beyond Google. ChatGPT, Perplexity, Gemini, and Copilot are all being used by people researching products, services, and suppliers. Brand mentions and content citations in these tools represent a form of visibility that did not exist two years ago and is growing rapidly. Businesses that optimise for this channel now are building a presence that latecomers will find increasingly difficult to establish.

What GEO Optimisation Involves in Practice

GEO builds on strong traditional SEO foundations. Content that is technically sound, well-structured, and authoritative in its subject matter is more likely to be cited by AI systems than thin or poorly organised content. From there, GEO-specific work includes structuring content with clear, direct answers to specific questions — FAQ schema, definitional paragraphs, and structured summaries that AI systems can extract cleanly. It also involves ensuring consistent entity association across multiple platforms: your website, Google Business Profile, trade press mentions, directory listings, and social profiles should all consistently associate your business name with your area of expertise and location.

Brand mentions across high-authority sources — the kind of editorial backlinks that traditional SEO values — carry additional weight in GEO because AI training data and citation logic tend to favour content that is widely referenced from credible sources. The link building strategy and the GEO strategy are therefore closely connected.
