What is Answer Engine Optimisation (AEO)?
AEO is the discipline of getting your brand named in AI-generated answers. It builds on SEO but targets a different output: not a ranked page, but a named recommendation.
The difference in the output
Search engine optimisation (SEO) helps your pages rank in results lists. When it works, a user sees your link, clicks it, and you get traffic. The user still decides what to do with the information.
AEO targets a different moment: the AI-generated answer. When a buyer asks ChatGPT which project management tool to use, or asks Google AI which CRM is best for small teams, the AI names one or two brands and explains its reasoning. AEO is the work that gets your brand into that answer — consistently, across multiple engines, for the queries that matter to your business.
The four AI engines AEO targets
Blends training data with web retrieval. Shows citations when web search is used. Most widely adopted for product and brand research queries.
AI-generated summaries shown above organic search results. Pulls from pages Google crawls — structured data and clear content are critical.
Retrieval-augmented answers with direct source citations. Weighted heavily toward recent, well-structured content and trusted sources.
Conversational AI with web browsing capability. Strong preference for clear, well-organised content with explicit fact statements.
What AEO requires that SEO doesn't
A strong SEO foundation is a prerequisite for good AEO — crawlability, information architecture, and authoritative content all carry over. But AEO adds several layers that traditional SEO work doesn't cover:
AI systems can't infer what you offer from unstructured marketing copy. schema.org markup makes it machine-readable.
FAQ pages, comparison pages, use-case descriptions, and feature explanations are the content AI systems pull from most often.
An emerging standard that gives AI engines a structured map of your most important pages — which sections exist and which URLs to prioritise.
AI systems build a picture of your brand from many sources. If your category, audience, and positioning are described differently on your site, G2, LinkedIn, and press mentions, the AI gets a confused picture.
Review platforms, editorial roundups, category directories, and press coverage all feed AI training and retrieval. Presence on them improves recommendation probability.
How AEO and SEO work together
The best approach is to run both in parallel rather than treating them as separate programmes. SEO builds the discoverable, authoritative pages. AEO makes those pages easier for AI systems to quote, summarise, and recommend.
In practice: your technical SEO foundation (fast pages, clean URL structure, crawlability) supports AEO. Your AEO work (structured data, FAQ content, llms.txt) often improves SEO signals too. The divergence is in content strategy — AEO pushes you toward answer-first content rather than keyword-volume-first.
