What is GEO? GEO stands for Generative Engine Optimisation — a method for optimising your business’s visibility in AI-powered search engines such as ChatGPT, Perplexity and Gemini.
What is the difference between SEO and GEO? SEO optimises for Google’s search results — you’ll be given a link to click on. GEO optimises for AI responses — your name is quoted directly in the response.
Why is GEO important in 2026? More than one in three Danes aged between 18 and 45 use ChatGPT to search for local services. When they ask “Recommend a good accountant” and your name isn’t in the AI response, the customer will go to a competitor.

If you’re still only optimising for Google, you’re missing out on customers who ask ChatGPT. GEO (Generative Engine Optimisation) is about being recommended in AI responses. SEO is about ranking in Google. By 2026, your SME will need to use both. Here’s the difference, and how to get started with GEO in just 10 minutes a week.
What is the difference between SEO and GEO?
GEO (Generative Engine Optimisation) is a method for optimising your business’s visibility in AI-driven search engines such as ChatGPT, Perplexity, Gemini and Copilot. In 2026, more and more Danes are using AI instead of Google to find local services such as accountants, plumbers and solicitors. GEO differs from traditional SEO in that it is optimised for AI responses rather than search results pages. At Geoa, we use GEO to measure and improve your visibility across all AI platforms.
Whereas traditional SEO optimises your website to rank in Google’s search results (SERP), GEO optimises for the answers that AI systems provide to their users. SEO is about getting clicks. GEO is about being cited. In 2026, 68 per cent of all Google searches will end without a click through to a website (SparkToro/Similarweb, June 2026) — note that this figure relates to the US; there is no corresponding Danish figure. We have previously stated that the proportion for ChatGPT and Perplexity is “83–93 per cent”; we were unable to substantiate that figure, and it has been removed.
Why is GEO important for your SME in 2026?
Here’s the short version: Your customers no longer just use Google — they also ask AI. In April 2026, Dansk Erhverv found that 45 per cent of Danes had used AI in connection with an online purchase within the past six months. When they ask “Recommend a good accountant” or “Which plumber should I choose?”, they receive a reply containing 3–5 names. If your name isn’t in that reply, the customer will go to a competitor whose name is.
The difference between SEO and GEO is fundamental: SEO is optimised for a search engine (Google) that displays lists of links. GEO is optimised for AI models (ChatGPT, Perplexity, Gemini) that provide a single, comprehensive answer. In SEO, you can rank #1 through technical optimisation. In GEO, you need to be cited as an authority — and that requires fact-rich, structured content with source references.
How does GEO work in practice?
GEO is based on peer-reviewed research presented at KDD ’24 (Aggarwal et al.), which shows that specific optimisation techniques can boost AI visibility by up to 40 per cent. The most effective techniques in the study were adding quotes from named individuals and adding statistics (both yielding a 30–40 per cent increase in the study’s primary metric). Source references yielded up to +115 per cent — but only for a page ranked 5th; for a page that was already ranked 1st, the effect was negative.
In practice, GEO means that you: (1) create content that answers the specific questions your customers ask, (2) structure it using facts, figures and source references, (3) ensure that AI crawlers can read your page (robots.txt, llms.txt, JSON-LD schema), and (4) update the content regularly so that AI models have up-to-date data to cite. Geoa does all this automatically — you’ll receive ready-made content every week.
What’s the difference between SEO and GEO? — Overview
| Dimension | SEO | GEO |
|---|---|---|
| Target audience | Google searchers | AI users (ChatGPT, Perplexity, Gemini) |
| Output | Ranking in search results | Citation in AI responses |
| Source references | Important for authority | Crucial — up to +115% (page ranked 5th) |
| Update frequency | Monthly–quarterly | Weekly (AI models are updated constantly) |
| Technical requirements | High (meta tags, sitemaps, speed) | Low (content > technical aspects — copy-paste) |
| Time required per week | 5–10 hours (technical changes) | 10 minutes (copy-paste content) |
How do you get started with GEO?
You don’t need to choose between SEO and GEO — they complement each other. A good SEO technical foundation (fast-loading page, correct schema, mobile-friendly) is also beneficial for GEO. But GEO requires something extra: content designed to be cited by AIs.

Our own case study: Relark.dk — a React-based site that started with a GEO Score of 49.9 (F), with AI crawlers blocked in robots.txt and content that was only loaded via JavaScript. The case study shows exactly which fixes were made and what they rectified. We do not publish an ‘after’ figure for AI visibility until we have measured it over a period we can stand by.

Frequently asked questions about SEO vs GEO
Should I drop SEO and focus solely on GEO?
No. SEO and GEO complement each other. A solid technical foundation for SEO (fast page, correct schema, mobile-friendly) also benefits GEO. However, if you only optimise for Google, you’ll miss out on the AI searches where your name needs to appear in the answer itself — not just as a link on a results page.
How long does it take for GEO to work?
You’ll get your GEO-score in 60 seconds. Visible improvements in AI answers typically occur within 2–4 weeks with weekly content delivery. AI models such as ChatGPT and Perplexity update their training data on an ongoing basis, so new content can affect your visibility more quickly than traditional SEO (which typically takes 3–6 months).
Does GEO work for all sectors?
GEO works best for local services — accountants, plumbers, solicitors, dentists, psychologists, estate agents and the like. This is where people most often look for recommendations on AI. We have industry-specific templates for over 30 sectors, so the content is tailored precisely to your location and area of expertise.
