What is Generative Engine Optimisation (GEO)?
Generative engine optimisation is the practice of making your website content easier for AI tools to find and interpret. It is related to SEO, but the practices and what is known about them differ. Nothing here guarantees mentions or citations.
Check your website readiness free →The short definition
Generative engine optimisation (GEO) is structuring your website content so that AI tools can find it and interpret it clearly. The aim is that your business information is accessible and unambiguous if an assistant uses it.
When a potential customer asks an AI assistant "who does X in Switzerland?", many things influence the answer, most of them outside your website. GEO addresses only the part you control.
GEO vs SEO — what's different
| Factor | SEO | GEO |
|---|---|---|
| Target | Google ranking algorithm | AI model extraction |
| Practices discussed | Backlinks + keywords | Entity clarity + structure |
| Content format | Keyword density | Answer-first, factual |
| Schema | Helps search features | Helps make business facts explicit |
| robots.txt | Googlebot | GPTBot, ClaudeBot, PerplexityBot |
| Measurement | Search rankings | Sampled AI answers to defined prompts (a tailored diagnostic) |
| Speed of impact | Weeks to months | Varies and cannot be predicted |
The six GEO fundamentals
AI crawler access
Check whether your robots.txt blocks AI crawlers such as GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot and Google-Extended. Some sites block them inadvertently; others block them on purpose.
Entity clarity
Make it clear who you are. Organisation schema on your homepage, a consistent brand name across pages, and a clear description of your service and location help tools identify your business.
Answer-first content
Tools that summarise pages often draw on opening text. Consider opening each page with a direct, factual statement rather than a welcome message or a marketing claim.
FAQ markup
Question-and-answer content with FAQPage schema makes the structure explicit. Write FAQs for the questions your customers actually ask.
Topical authority
A coherent set of pages covering your service area in depth gives readers and tools more to work with than a single page. We cannot say how AI assistants weigh this.
llms.txt
An emerging, optional convention: a plain-text file at /llms.txt that briefly describes your business. Support among AI tools is limited and varies.
GEO implementation checklist
The practical work is usually small. A Swiss SME does not need hundreds of AI-written pages. It needs a site that clearly states who the business is, what it does, where it operates, and which customer questions it answers better than generic sources.
| GEO layer | What to add | Why it may help | How to verify |
|---|---|---|---|
| Crawler access | Explicit Allow rules for GPTBot, ClaudeBot, PerplexityBot, and Google-Extended | Makes clear the content is available to those crawlers | Check /robots.txt and crawl logs |
| Entity schema | Organization, WebSite, Article, and FAQPage JSON-LD where appropriate | Makes the business, topic and answer format explicit | Validate structured data and inspect page source |
| Answer-first copy | A direct answer in the first paragraph of each important page | Gives a concise extract that is easy to quote or summarise | Read the first 100 words without page context |
| Topical depth | Dedicated pages for the questions buyers actually ask | Shows expertise beyond one thin landing page | Map target prompts to specific URLs |
| AI brief | A maintained /llms.txt file listing services, locations, and key pages | Offers a plain-text business summary | Open /llms.txt and confirm it matches the site |
How to measure your GEO performance
Our free check is an automated review of your website, not of AI answers. It returns a Website Readiness Score (0–100) based on the factors described on our score methodology section, and highlights up to three issues. AI crawler access and llms.txt are reported separately and do not change the score. The free emailed report adds per-page results and a small sample of AI answers. Measuring how AI assistants answer buyer questions for your market and languages is a tailored diagnostic.
Frequently asked questions
What is generative engine optimisation? +
GEO is the practice of structuring website content so AI tools can more easily find and interpret it. It covers technical and content practices that may help; none guarantees that an assistant will cite or recommend a business.
How is GEO different from SEO? +
SEO targets search ranking signals such as backlinks, keywords and page authority. GEO focuses on features that may help AI tools read content: entity clarity (schema), answer-first structure, FAQ markup and crawler access. How assistants weigh these is not public.
Why does GEO matter for Swiss businesses? +
Some Swiss buyers use AI assistants to research services before making contact. Making your website clear and accessible to those tools is a low-risk step, but we cannot say how much of your market uses them, and nothing is guaranteed.
What are the most important GEO factors? +
Commonly discussed practices: (1) check whether robots.txt blocks AI crawlers, (2) Organisation schema, (3) answer-first content, (4) FAQ sections with markup, (5) content depth, (6) optional llms.txt. The relative importance of each for AI assistants is not established.
