AI search and GEO, what it is and why your business needs to act now

Search is undergoing fundamental change. What has for years been a simple process, the user types a keyword, Google returns a list of links, is today being replaced by something far more complex. AI search engines and chatbots generate direct answers to users’ questions, and they decide themselves which businesses and sources to feature. That creates new opportunities for businesses that act now, and a real risk for those that wait. This article explains what AI search is, what GEO means, and what you can concretely do to secure your business’s visibility in the new search landscape.

What is AI search?

AI search is a collective term for search experiences driven by artificial intelligence rather than traditional algorithmic ranking systems. Instead of returning a list of links, AI search engines generate a summarised answer directly in the search result, drawn from and based on content from a selection of chosen sources across the web.

The most widely used AI search platforms today are Google SGE (Search Generative Experience), ChatGPT from OpenAI, Perplexity AI and Microsoft Copilot. What they all have in common is that they do not simply show which pages rank highest, they interpret the user’s question, compose an answer and decide themselves which businesses and experts are credible enough to be cited.

What is the difference between AI search and traditional SEO?

Traditional SEO is about ranking in Google’s blue links, the organic search results ranked by relevance and authority. AI search is about being selected as a source when an AI engine generates an answer. These are two fundamentally different mechanisms. In traditional SEO, the goal is a high position in a list. In AI search, the goal is to be mentioned, cited, or recommended directly in an AI-generated answer. Typically, there is only room for 2–5 sources per answer.

Example: A user asks Perplexity ‘How much does an SEO consultant cost in Denmark?’ Instead of showing a list of links, Perplexity generates a direct answer and cites 2–3 specific sources. The businesses selected as sources appear as the most authoritative answers to the user’s question, and are the only ones with real visibility in that answer.

What is GEO

GEO is the discipline of optimising your business’s digital presence so that AI search engines choose you as a source in generated answers. It is the natural response to the spread of AI search, just as traditional SEO was the response to Google’s organic search results.

GEO is not a replacement for SEO; it is a complement. The two disciplines share many fundamental principles: strong and authoritative content, technically correct setup, and consistent information across the web. But GEO additionally requires specific approaches to how content is structured, written, and contextualised in order to be understood and selected by AI engines.

What sets GEO apart from traditional SEO?

Traditional SEO focuses on keyword placement, backlinks, and technical page optimisation. factors that influence where you rank in a list. GEO focuses on entity-based visibility, passage retrieval, and information consistency, factors that influence whether an AI engine considers your business a credible and relevant source. GEO requires that your content be written as standalone, authoritative answers that can be extracted and used directly by an AI, not just texts that rank well for specific keywords.

How do AI search engines work technically?

To understand what it takes to be visible in AI search, it helps to understand how AI engines work. Most AI search engines use a combination of two approaches: index-based search (like Perplexity and Google SGE) and LLM-based knowledge (like ChatGPT in its basic form).

Index-based AI search

Platforms such as Perplexity and Google SGE actively search the web, identify relevant pages, and extract passages from them to compose an answer. Here, traditional SEO authority still matters; if your page is not indexed and ranking at all, the AI engine will never find it. But GEO optimisation determines whether your page is actually selected as a source over a competitor with similar authority.

LLM-based knowledge

Platforms such as ChatGPT draw primarily on the knowledge embedded in the language model itself during training. That means your business’s presence in AI answers here depends on whether you are mentioned broadly and authoritatively enough across the web to have become part of the model’s knowledge base. This is a long-term process that requires consistent presence across platforms, media and industry publications.

What does GEO optimisation require in practice?

There are several different elements, and here you can read about the most basic ones.

Entity optimisation and brand consistency

AI engines work with entities, clearly defined objects such as businesses, people, products, and places. Your business must appear as an unambiguous and consistent entity across your website, Google Business Profile, LinkedIn, industry directories, and press mentions. Inconsistent information, varying company name, conflicting descriptions of services, or missing contact details, weaken AI engines’ trust in you as a source.

Structured data and Schema.org

Schema.org markup is one of the strongest signals you can send to AI engines about who you are and what you offer. Organisation markup explicitly tells AI engines your company name, what you do and how to contact you. FAQ markup makes your questions and answers directly available as passage retrieval candidates. LocalBusiness markup is essential for local AI visibility.

Passage retrieval and standalone answer sections

AI engines do not extract entire pages; they extract specific passages that answer a particular question. That means every section on your website should be able to stand alone as a meaningful and complete answer to a relevant question. Long, unstructured texts without clear H2 and H3 headings are difficult for AI engines to work with. Concise, precise, and well-structured content is far better suited.

Semantic SEO and topical authority

AI engines do not evaluate individual keywords alone; they evaluate the overall thematic depth of your website. The more consistently and thoroughly you cover a topic across your pages, the more likely an AI engine is to consider you an authoritative source in that field. This is the same logic as traditional SEO topical authority, but it is even more important in the context of AI search.

Why should your business act now?

AI search is not the future; it is the present. Google SGE is already integrated into Google’s search results in many countries. ChatGPT is used by over 200 million active monthly users for searching and research. Perplexity is growing as a Google alternative. The business that optimises early builds visibility and a digital footprint that is difficult for competitors to catch up with.

Businesses that currently rank well in traditional search results are not automatically visible in AI answers. And conversely: lesser-known businesses with well-structured, authoritative content can appear as the preferred sources in AI-generated answers, even ahead of larger competitors. This is a window that is open now, but that will close as competitors begin to optimise.

AI search is one of the only areas in digital marketing where early action creates a competitive advantage that is difficult to catch up with. The businesses that are present in AI answers today are building a presence that is much harder to displace than a traditional Google ranking.

AI search and GEO in relation to your other marketing channels

GEO and AI search optimisation do not work in isolation, they are part of the overall digital strategy. SEO builds the technical and content-based foundation that AI engines draw on. Content marketing produces the authoritative texts that are the basis for passage retrieval. Social media and mentions across platforms build the entity-based breadth that AI engines evaluate. And the omnichannel approach ensures your business appears consistently everywhere, precisely as AI engines expect.
