Frequently Asked Questions
What is an AEO agency?
An AEO (Answer Engine Optimisation) agency specialises in optimising your brand's content to be cited as an authoritative answer by AI search engines like ChatGPT, Gemini, and Perplexity. The term AEO was coined by First Page Sage and refers to the practice of structuring content so that AI models select and reference it when generating answers to user questions.
What is the difference between AEO and GEO?
AEO (Answer Engine Optimisation) focuses on getting your content cited as a direct answer by AI engines. GEO (Generative Engine Optimisation) is a broader discipline that includes AEO but also covers brand visibility, sentiment, and representation across all AI-generated content. In practice, most agencies use the terms interchangeably, though AEO tends to emphasise the answer-citation aspect.
