The difference between SEO and GEO lies in where customers find your business. SEO, or search engine optimisation, ensures that your website appears high up in Google and Bing’s search results, where people choose a link themselves and click through. GEO, or Generative Engine Optimisation, ensures that ChatGPT, Gemini and Claude.ai mention and recommend your business in the answers they generate themselves. SEO is all about rankings and visitors, whilst GEO is about mentions and trust in an AI-generated answer. Both are built on the same solid foundation of strong content, a technically sound website and a brand that exudes online authority.
For SMEs in Belgium, this distinction is more important today than ever before. More and more people are first putting their question to ChatGPT, Gemini or Claude.ai and immediately receiving a comprehensive answer featuring a handful of company names. Anyone who understands the difference between SEO and GEO also knows where they need to be positioned to appear in that answer and gain trust even before a website is visited.
What SEO actually does
Search engine optimisation focuses on traditional search engines. Google and Bing send crawlers across the web, store pages in a vast index and rank those pages according to hundreds of signals. Your website’s technical aspects are taken into account, as are the quality of your content, the user experience and the links from other websites to yours. The searcher is presented with a list of results, supplemented by maps, images and local listings, and chooses for themselves which website appeals to them most.
Success in SEO can be clearly measured. You can track rankings, impressions, clicks and conversions in Google Search Console and see, month after month, which pages are growing. If you want to get started yourself, you’ll find a solid foundation in our blog post on rank higher on Google.
What exactly GEO does
Generative Engine Optimisation focuses on language models that compose their own answers. ChatGPT, Gemini and Claude.ai read a question, analyse its meaning and write a response in plain, human language. Some models draw primarily on their training data, whilst others search the web in real time and summarise the best sources. Google AI Overviews and AI Mode, for example, build on Google’s search index, as Google itself explains in its guidelines on AI features and your website.
GEO’s aim is to ensure your brand is mentioned in that response, preferably in a positive light and with a link to your website. The more often a language model encounters your company as a reliable source – on your own website and elsewhere on the web – the greater the chance that it will recommend your name.

Five differences you’ll notice in practice
As an entrepreneur, you’ll notice the difference between SEO and GEO in five areas, ranging from the technology behind search to the way you measure results.
The technology behind search
Google compares a search query with the pages in its index, taking into account keywords, links and technical factors. A language model translates words into meaning and searches for content that is thematically close to the query. Anyone searching for an accountant who works with start-ups will therefore also be shown a page about helping start-ups with their first annual accounts. Google itself has been using language understanding for years, but still displays the results as a list.
The way the answer appears
For the searcher, the difference between SEO and GEO lies mainly in what they see. On Google, the searcher is given a choice and clicks through to a website. In ChatGPT, Gemini and Claude.ai, they immediately read a full answer and are much less likely to click through. The mention in that answer thus becomes the first point of contact with your brand, and often also the moment when someone decides to search further using your name.
What you measure and monitor
You can also see the difference between SEO and GEO in the follow-up. SEO is measured in rankings, clicks and conversions. GEO is measured in mentions, in the tone a model uses when talking about your business, and in the position you occupy amongst your competitors. To do this, we feed the questions your customers ask to ChatGPT, Gemini and Claude.ai, and track how often your brand appears.
How to write content
The difference between SEO and GEO also determines how you write. For SEO, you build a page around a focus keyword and the search intent behind it. For GEO, you also write in such a way that a language model can easily take over a section of text. An opening paragraph that answers the question straight away, clear headings, short definitions and a block of frequently asked questions help with this. Many AI crawlers only read the raw HTML, so a logical structure with H1, H2 and H3 headings is very important. Texts generated directly by an AI tool tend to perform less well in this respect, as you can read in our blog post about AI content and SEO.
The role of your brand beyond your website
Outside your website, the difference between SEO and GEO becomes even clearer. For SEO, backlinks carry significant weight. For GEO, a language model takes a broader view of everything the web says about your business. Reviews, mentions in trade publications, customer stories, your Google Business Profile and consistent information across directories all work together to reinforce the image of a trustworthy brand.
Where SEO and GEO complement each other
There is a significant difference between SEO and GEO in terms of how they work and how they are measured, yet both channels share much of the same foundation. A fast, well-structured website, content that fully answers questions, and a strong reputation will help you on Google and with AI alike. Furthermore, various language models draw their up-to-date information from search engines. Anyone who ranks highly on Google and Bing therefore also increases their chances of being included in an AI response.
Both channels also aim to achieve the same thing: helping a searcher find the best answer. Google assesses content based on experience, expertise, authority and trustworthiness, whilst language models look for sources that convey precisely those signals. Anyone familiar with the difference between SEO and GEO therefore sees GEO as an extension of SEO, with its own techniques, its own tools and its own way of measuring.
