Answer Engine Optimization (AEO), also known as AI SEO, Generative Engine Optimization (GEO), or AI Optimization (AIO), is the practice of optimizing your content in a way for AI systems like ChatGPT, Google Gemini, and Perplexity to more likely use and reference your content within their responses.
AEO isn’t a replacement for SEO. The same fundamentals still matter and a very much applicable: strong structure, good speed and page performance, clear intent alignment, trustworthy sourcing, and topical depth. The difference is in how those same fundamentals are prioritized tactically to make your content easier for AI systems to understand, extract, and cite as users increasingly rely on AI-generated answers.
