Answer Engine Optimisation
Also known as: AEO
The practice of structuring content so it can be lifted directly into AI answers. Close cousin of GEO; emphasises clean, parseable facts and unambiguous attribution.
What it is
Answer Engine Optimisation is the practice of structuring content so discrete facts can be lifted directly into AI answers with minimal reshaping. It is a close cousin of GEO that emphasises clean, parseable statements and unambiguous attribution over narrative flow.
Why it matters
Answer engines reward content they can extract confidently, so parseable facts increase the odds of being selected and reduce the risk of misattribution. It positions a brand as the canonical source for a specific answer.
How it works
Write one clear fact per sentence, pair claims with named sources and dates, and use structured formats such as definition lists, tables, and schema markup so machines can map question to answer. Remove hedging language that makes a fact ambiguous to extract.
When it applies
It applies to factual, definitional, and how to queries where a single correct answer can be stated plainly.
Examples
- A recipe site marks up cooking times and yields so an assistant returns the exact figure when asked.
- A finance glossary states each definition in a single unambiguous sentence and becomes the quoted source for that term.
- A support knowledge base reformats troubleshooting steps into numbered, self contained instructions that an assistant reads back verbatim.
How it is measured
- Rate of correct attribution when your fact appears in an answer
- Number of distinct questions for which you are the extracted answer
- Coverage of target questions with a clean, parseable answer on page
- Reduction in answers that cite a competitor for facts you also publish

- Agentic researchAgentic research is the use of an AI system that plans and carries out a multi-step research task on its own, running many searches, opening and reading sources, then writing a synthesised answer or report with citations. It differs from a single search query because the model decides what to look up next based on what it has already found. Vendors often market this capability as deep research.
- Citation-worthy contentContent with the qualities LLMs select for when synthesising an answer: a single, defensible claim per paragraph; named entities; first-hand evidence; and a clear authority signal.
- Content auditA content audit is a structured review of every page or asset in a content set, scored against performance, quality, accuracy and search intent. The output is a decision for each item: keep, improve, consolidate, redirect or remove. It turns a large and uneven content library into a prioritised action plan.
- Crawler policyA crawler policy is the set of rules a site publishes and enforces to decide which automated agents may access its content, how often, and for what purpose. It typically combines robots.txt directives, server side rules and terms of use, and increasingly distinguishes search crawlers from AI training and assistant crawlers. The policy defines both what is allowed and what happens when a bot ignores it.
- Digital discoveryThe full set of channels through which people find brands, products, and answers, search engines, AI assistants, social platforms, marketplaces, and agentic browsers. Replaces the narrower frame of just “SEO”.
- Ecommerce SEOEcommerce SEO is the practice of making an online store's category, product, brand and editorial pages discoverable in organic search. It combines technical work on crawling, indexing and site structure with commercial decisions about which queries each page should serve. The goal is qualified non-paid traffic that converts into orders.
