What is AEO? Answer Engine Optimisation, explained
By Oliver Woodhead · 21 July 2026
AEO, or Answer Engine Optimisation, is the practice of making a business visible, accurate and citable inside AI answer engines such as ChatGPT, Claude, Perplexity and Google AI Overviews. This article, from Momentum Inspire, a commercial growth consultancy for ambitious UK businesses, explains what AEO involves, how it differs from SEO, and how a UK SME should judge whether it needs it.
Why does AEO exist?
Buying behaviour changed. A growing share of buyers now ask an AI assistant a question, “who should I use for X in the UK?”, and act on the single answer they get, instead of scanning a page of ten blue links. When that happens, there is no page two. A business is either part of the answer or it is invisible to that buyer.
Answer engines build their responses from what they can read, extract and trust on the open web. AEO is the discipline of deliberately meeting those three tests: letting the engines in, structuring content so they can quote it, and giving them verifiable reasons to trust it.
What does AEO actually involve?
In practice AEO is three layers of work. The technical layer opens the door: allowing AI crawlers in robots.txt, publishing an llms.txt file and a sitemap, and making sure content renders without JavaScript. The content layer makes pages quotable: definition-first openings, question-led headings answered directly, and real lists and tables instead of marketing prose. The trust layer gives engines a reason to cite you: structured data that names the legal entity, named authors with real profiles, and claims that trace to a source.
None of the three layers is optional. A technically perfect site with vague, anonymous content is as invisible as a well-written site the crawlers cannot reach.
How is AEO different from SEO?
SEO competes for a position on a results page; AEO competes for a mention inside the one answer an assistant gives. The two overlap, since both reward fast, well-structured, trustworthy sites, but they diverge in what they optimise for. SEO thinks in keywords and rankings. AEO thinks in questions, extractable answers and entities: can an engine lift a correct, attributable answer about you straight off the page?
The practical consequence is that good SEO does not automatically produce AEO results. A site can rank respectably on Google and still be absent from AI answers because its content cannot be extracted or its identity cannot be verified.
Does my business need AEO?
Run one honest test: ask ChatGPT, Claude and Perplexity the question your ideal customer would ask, “who are the best [what you do] for [who you serve] in the UK?”, then see whether you appear, and whether what is said about you is accurate. If you are absent or misdescribed, that is the gap AEO closes.
Momentum Inspire publishes the six-pillar AEO Maturity Score it uses to measure this properly, so any score can be checked rather than taken on trust. Our own July 2026 audit of our previous site scored 15 out of 100, which is why this site was rebuilt to the same discipline we sell.
Frequently asked questions
- Is AEO just a new name for SEO?
- No. They share foundations, since both need crawlable, fast, trustworthy sites, but AEO optimises for being quoted in a single AI-generated answer rather than ranked on a results page. The work diverges in structured data, extractable copy and entity verification, which traditional SEO rarely covers.
- How long does AEO take to work?
- Technical fixes are read by engines within weeks of a re-crawl; movement in actual AI answers typically follows over one to three months. Anyone promising a guaranteed placement in a specific engine on a specific date is selling something nobody controls.
- Can I do AEO myself?
- The principles are public, and this site publishes its full methodology at momentuminspire.com/methodology. What a consultancy adds is the technical implementation, the editorial discipline across every page, and monthly measurement of how engines actually answer. Some SMEs do the basics in-house and bring in help for the rest.
