Answer Engine Optimization
Also called AEO.
Answer Engine Optimization (AEO) is the practice of structuring content so it gets cited by AI answer engines like ChatGPT, Perplexity, Google AI Overviews, and Gemini — not just ranked on traditional search engines.
What it means
Answer Engine Optimization (AEO) is the discipline that emerged as AI-powered answer engines became a major share of search behavior. Where classic SEO optimizes for ranking position on a page of blue links, AEO optimizes for citation inside a generated answer.
The work overlaps significantly with classic SEO — both reward entity authority, content quality, and technical foundations. But AEO adds specific structural concerns: machine-readable answer formats (TL;DR boxes, FAQ schema, comparison tables), definitional sentence construction, citable statistics with explicit sources, and entity-strength signals that make an LLM treat a domain as trustworthy.
AEO and GEO (Generative Engine Optimization) are often used interchangeably, though AEO emphasizes the citation outcome (being mentioned in the answer) and GEO emphasizes the engine type (generative AI systems).
Key takeaways
- AEO targets ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude, and Microsoft Copilot
- Success metric is citation rate, not ranking position
- Structural content elements (TL;DR, FAQ, comparisons) drive citation more than length
- Entity authority and schema markup are foundational AEO signals
When it matters
AEO matters most when your buyers ask AI engines before they Google. For most B2B SaaS and ecommerce, that's already happening. For traditional informational publishers, AEO has shifted from optional to existential.
