Answer Engine Optimization (AEO)

Definition
Answer Engine Optimization (AEO) is the page-level discipline of formatting content so answer engines can extract a complete, attributable passage and cite it inside a generated response. The core mechanic is an answer-first block — typically 40–60 words placed immediately after a question-style heading — written to stand alone without surrounding context.
What AEO actually does
AEO is content engineering for extraction. An answer engine does not reward a page for being long or keyword-dense; it rewards passages that can be lifted as a discrete unit — a definition, a step, a comparison — and inserted into a generated answer with minimal editing. The practical unit is the answer block: a declarative paragraph that answers one question completely, in plain language, with a named entity and a verifiable claim where possible.
Supporting mechanics include FAQPage and HowTo structured data, question-form headings that mirror how buyers ask prompts, and statistics paired with a named source and year so the model can attribute them.
How AEO differs from GEO and SEO
SEO optimizes for ranking a URL. GEO optimizes for whether the brand is citation-worthy across the AI ecosystem. AEO sits between them at the page level: it determines whether this specific page is extractable. A brand can run a strong GEO program — consistent entity, earned mentions, third-party coverage — and still lose citations because individual pages bury the answer under navigation prose and marketing fluff. AEO fixes that layer.
In Asian markets
Extraction rules do not change by country, but what gets extracted does. Models answering in Japanese or Korean prefer in-language answer blocks; an English-only FAQ on a .com domain rarely surfaces in localized answers even when hreflang is correct. AEO in Asia means native-language answer blocks per market, not translated summaries appended to an English template.
Example
A pricing page adds a 52-word answer under “What does [product] cost in Singapore?” with FAQPage schema and a last-updated date. Perplexity begins citing that block for cost-comparison prompts — first in English, then after a Bahasa block ships, in Indonesian queries covering the same category.
