Answer Engine Optimisation (AEO)
In short
What is answer engine optimisation (AEO)?
How does answer engine optimisation work?
AEO works by making your facts easy for a language model to extract and safe to repeat. Instead of optimising only for keyword rankings, you write a short, accurate answer at the top of a page, support it with structured data, and reinforce it with consistent information about your business across the web. Answer engines then have a clear, trustworthy source to quote when a user asks a related question.
The shift matters because behaviour is changing fast. Gartner forecasts that traditional search engine volume will drop by around 25 per cent by 2026 as users move to AI assistants and answer engines (Gartner, 2024). If a model cannot read your answer cleanly, it will quote a competitor instead.
How is AEO different from SEO?
SEO competes for position in a list of links. AEO competes to be the sentence the AI actually says. With AEO you are optimising for extraction and trust rather than clicks alone, so the work centres on answer-first copy, schema markup, and a coherent entity graph that ties your name, services and location together. The two disciplines share foundations, but their success metric differs: rankings versus citations.
- Answer-first content: a direct 40 to 60 word answer near the top of each page.
- Structured data: schema such as FAQPage, Organization and DefinedTerm that labels your facts.
- Entity authority: consistent mentions and citations across trusted sources.
Why does AEO matter in 2026?
Answer engines increasingly sit between your customer and your website. When Google AI Overviews or ChatGPT answer a question directly, the citation, not the tenth blue link, drives awareness and trust. Adoption is now mainstream: Pew Research Center found that AI Overviews appeared in roughly one in five Google searches in its 2025 analysis (Pew Research Center, 2025), and click-through to external links fell when a summary appeared. Being the cited source protects your visibility as clicks shrink.
A concrete example of AEO in action
Consider a Parramatta accounting firm whose service page once opened with a slogan and a stock photo. After applying AEO, the page begins with a plain sentence: "We are a Parramatta accounting firm offering tax, bookkeeping and advisory services to NSW small businesses." That line is wrapped in Organization and FAQPage schema, and the firm is described identically across its directory listings.
When a user later asks an answer engine, "who does small business tax in Parramatta?", the model has a clean, consistent fact to repeat and cite. That is AEO: not a trick, but making your true answer the easiest one for a machine to quote.
Key takeaway
AEO is won by being accurate, structured and consistent. State your answer plainly, mark it up with schema, and keep your entity details identical everywhere so AI engines can read, trust and cite you.

Answer engine optimisation, answered
Answer engine optimisation is the practice of structuring your content, data and authority so AI answer engines like ChatGPT, Perplexity, Gemini and Google AI Overviews quote your business directly. It combines answer-first writing, structured data and a connected entity graph so machines can read, trust and cite you.
SEO earns clicks by ranking blue links on a results page. AEO earns mentions inside the AI answer itself, often before any link is shown. SEO still matters, but AEO targets how machines extract, trust and cite facts about your business. The two work best together.
They overlap heavily. AEO focuses on being the cited answer in answer engines, while generative engine optimisation (GEO) is the broader practice of being recommended across generative AI. In day to day work the techniques, schema and entity authority are largely shared.
Begin by writing a 40 to 60 word answer-first summary at the top of each key page, add accurate schema such as FAQPage and Organization, and build a consistent entity profile across the web. Then track which AI engines cite you and refine from there.
