GEO Optimisation: The Complete Guide for Businesses (2026)
SHORT ANSWER
GEO optimisation (Generative Engine Optimization) is the process of making a business visible and cited in answers from AI systems like ChatGPT, Claude and Gemini. The most important measures are technical — JSON-LD schema, llms.txt and FAQPage format. Documented results typically appear within 3–6 weeks.
What is GEO optimisation?
GEO optimisation is about structuring your website and content so that AI systems understand who you are, what you offer and who you help — and actively choose to recommend you. It is not content production. It is technical structure and machine-readable identity.
GEO vs SEO — what is the difference?
SEO optimises for Google's search algorithm and is measured in clicks and Google rankings. GEO optimises for AI systems and is measured by whether your business is mentioned and recommended in ChatGPT, Claude and Gemini. GEO uses schema markup, llms.txt and structured content — not primarily backlinks and keywords. The two disciplines complement each other but require different actions.
The 5 most important GEO measures
1) llms.txt — a plain text file that tells AI systems who the business is and what it does. 2) Organization JSON-LD schema in head — machine-readable identity. 3) FAQPage JSON-LD on all service pages — what AI systems cite most often. 4) Short answer boxes at the top of service pages — concise answers AI can extract directly. 5) Dedicated landing pages for long-tail search queries that AI systems answer.
Documented result: Digital Thinking
Digital Thinking (digitalthinking.no) implemented the GEO methodology and achieved top 1–3 Google rankings on almost all landing pages. Gemini and other AI systems actively cite Digital Thinking for searches about GEO and IT staffing in Norway. No Next.js. No content production. Just the right technical structure.
Do you need Next.js for GEO optimisation?
No. GEO optimisation works on all frameworks — Vite, React, WordPress and others. JSON-LD schema in head is read by AI systems regardless of framework. It is the content structure that determines AI visibility, not the technology choice.
