What is Answer Engine Optimization (AEO)?
Answer Engine Optimization (or Optimisation, in British spelling) means optimizing your website for answer engines - the AI assistants like ChatGPT, Claude, Perplexity and Gemini, built on large language models, that have exploded in popularity since ChatGPT launched in 2022.
Businesses have started asking a simple question: when a customer asks an AI for “the best [product or service] in [my location],” does my business come up - and how much revenue am I losing if it doesn’t? SEO meant being number one on Google. AEO means showing up in AI answers.
In practice, AEO is the work of making your website the source AI assistants use when they answer questions about your industry, your services, or your location. When someone asks ChatGPT or Claude “who’s the best physio in Leeds” or “which agency builds bilingual sites in Dubai,” the AI picks a handful of businesses to name. AEO is how you become one of them. You’ll also hear it called GEO (Generative Engine Optimization), LLMO, or AI SEO. Same discipline, different names.
