SEO (Search Engine Optimisation) focuses on ranking in Google and Bing’s traditional search results. AEO (Answer Engine Optimisation) extends this to AI-powered discovery platforms, making sure AI engines can read, trust and quote your business when they generate a search summary. GEO (Generative Engine Optimisation) targets large language models directly, ensuring your business appears in ChatGPT, Gemini and Perplexity responses. All three share common foundations: technical health, authoritative content and structured data.
