What is Answer Engine Optimization (AEO)?
AEO is SEO for the age of ChatGPT, Claude, and Perplexity — making your content machine-readable so AI assistants cite you.
TL;DR
Answer Engine Optimization (AEO) makes your content easy for AI assistants — not just search engines — to find, parse, and cite. The core moves: a direct 'answer box', structured TL;DRs, FAQ schema, and entity links.
Quick answer
Answer Engine Optimization (AEO) is the practice of structuring web content so that AI answer engines — ChatGPT, Claude, Perplexity, Google's AI Overviews — can reliably extract, paraphrase, and cite it. It complements SEO by adding three layers: a direct answer to the user's question above the fold, machine-readable schema markup (Article, FAQPage, BreadcrumbList), and explicit entity links (Wikipedia, Wikidata) that anchor your content in the AI's knowledge graph.
Key takeaways
- AEO is not a replacement for SEO — it sits on top of it.
- Lead every article with a 50–80 word direct answer.
- Emit Article + FAQPage + Breadcrumb JSON-LD on every post.
- Link your entities to Wikipedia/Wikidata via sameAs.
- AI assistants cite the source they can parse most cleanly, not always the highest-ranking one.
For two decades, Search Engine Optimization (SEO) meant one thing: rank in Google. That assumption broke in 2023. Now your customers ask ChatGPT, Perplexity, and Google's own AI Overviews — and those engines don't show ten blue links. They synthesize an answer and cite two or three sources.
What's actually different about AEO
AEO doesn't replace SEO; it adds a machine-readability layer on top. Three concrete additions: a direct answer in the first 80 words, schema.org JSON-LD on every page, and explicit entity links to authoritative graph nodes (Wikipedia, Wikidata, official sites).
Why the entity layer matters most
AI answer engines build their world model from entities — people, organizations, products, concepts — not from individual web pages. When your article links 'ChatGPT' to its Wikidata ID, you're telling the AI 'this content is about THIS thing,' unambiguously. That's the single highest-leverage AEO move.
Frequently asked questions
- Is AEO different from SEO?
- AEO complements SEO. SEO optimizes for ranking on a search results page; AEO optimizes for being cited and paraphrased by AI answer engines. You do both.
- Which schema.org types matter most for AEO?
- Article, FAQPage, BreadcrumbList, and Organization on every page. Add Product or HowTo if relevant.
