Introduction: What is Answer Engine Optimisation?

Answer Engine Optimisation (AEO) is the practice of optimising your content to be featured in AI-generated answers from tools like ChatGPT, Google AI Overviews, Perplexity, and other AI-powered search interfaces.

While traditional SEO focuses on ranking in search results, AEO focuses on being the source AI cites when answering questions.

"By 2026, 30% of all search queries will be answered by AI without users clicking through to websites. Being the cited source is the new ranking #1."
