Answer Engine Optimization (AEO)
AEO is the practice of structuring content so AI-powered answer engines — ChatGPT, Claude, Gemini, Perplexity — correctly cite your brand when synthesizing responses.
Definition
Answer Engine Optimization (AEO)is the discipline of improving a brand's citation rate, accuracy, and sentiment inside AI-generated answers. As AI-powered search engines displace a growing share of traditional search queries, a brand's visibility in those answers becomes a measurable business metric.
AEO practitioners focus on signals that help AI models identify and accurately represent a brand: structured data, entity disambiguation, consistent authority citations, and citation-ready content formatting.
Core AEO tactics
- FAQPage schema— structured Q&A pairs that AI engines can pull verbatim into answer summaries.
- Organization JSON-LD — unambiguous entity declaration with name, URL, logo, description, and SameAs links.
- llms.txt — a plain-text file at
/llms.txtthat gives AI crawlers a concise, authoritative brief. - Citation-ready snippets — concise, self-contained paragraphs at the top of key pages that LLMs can quote without truncation.
- Authority citations — Wikipedia, Wikidata, Crunchbase, LinkedIn Company Page, and press mentions that create a consistent entity signal.
- Disambiguation copy — explicit text that distinguishes the brand from other entities sharing a similar name.
Frequently asked questions
- What is Answer Engine Optimization (AEO)?

- Is AEO the same as GEO?
- The terms are used interchangeably by most practitioners. Some distinguish them: AEO focuses specifically on voice and text answer boxes (Siri, Alexa, featured snippets), while GEO (Generative Engine Optimization) focuses on LLM-generated responses. In practice, the tactics overlap — structured FAQs, schema markup, entity clarity, and llms.txt improve both.

- The highest-impact AEO tactics are: (1) FAQPage schema so AI engines can pull structured Q&A pairs directly, (2) Organization and SoftwareApplication JSON-LD to establish entity identity, (3) an llms.txt file that gives AI crawlers a concise brand brief, (4) concise, citation-ready paragraphs at the top of key pages, and (5) consistent brand descriptions across Wikipedia, Wikidata, LinkedIn, and Crunchbase.
