What is AEO? Answer Engine Optimisation Explained
Search has changed. Millions of people now get answers directly from AI — without clicking a link. Answer Engine Optimisation is the discipline of making sure your brand is the one those AI systems cite.

What AEO actually means
Answer Engine Optimisation (AEO)is the practice of structuring your content and online presence so that AI-powered systems — ChatGPT, Perplexity, Google's AI Overviews, Claude, Gemini — cite and accurately represent your brand when answering relevant questions.
Where traditional SEO targets search engine crawlers and ranking algorithms, AEO targets the large language models and retrieval systems that power the next generation of search. The goal is not to rank — it is to be cited.
AEO emerged as a discipline because LLMs do not return ten blue links. They return one answer. If your brand is not part of that answer, you are invisible — regardless of your domain authority or keyword rankings.
By 2025, AI-powered search tools had over 100 million daily active users collectively. Google AI Overviews appeared in over 40% of searches. The traditional SERP click was no longer the default user journey.
Most brands have zero AEO strategy. The teams that start optimising for AI answers now will own the citations that competitors scramble for in 2027.
AEO vs SEO
How AEO differs from traditional SEO
AEO and SEO are complementary — not competing — disciplines. Good SEO creates the foundations that AEO builds on. But their targets, metrics, and tactics differ significantly.
Core tactics
The four pillars of AEO
FAQ Schema Markup
Structured FAQ schema signals to AI systems which questions your page answers and what the correct response looks like. Pages with clear Q&A structure are disproportionately cited by LLMs.
Entity Clarity
AI models reason about entities — people, brands, products, places — not just keywords. Consistent, authoritative signals about who you are across the web improve how AI describes you.
Direct, Self-Contained Answers
Content that answers questions in the first paragraph — without requiring users to read through preamble — is far more likely to be surfaced verbatim in AI-generated responses.
E-E-A-T Signals
Experience, Expertise, Authoritativeness, and Trustworthiness remain central to AEO. AI systems are trained to favour content with genuine expertise markers — author bios, citations, original data.
Measurement
How to measure AEO performance
Unlike SEO, there is no single rank tracker for AEO. Measuring your AI visibility requires systematically prompting AI engines with questions your target customers ask, then auditing whether your brand appears — and how accurately it is described.
Key AEO metrics to track:
- Brand mention rate across ChatGPT, Perplexity, Claude, Gemini
- Answer accuracy — does the AI describe your product correctly?
- Share of voice vs competitors in AI-generated answers
- Citation source quality — which pages are being cited?
- Topic coverage — which relevant questions do you appear in?
