# Answer Engine Optimisation (AEO)

Expanded explanation

## Why Answer Engine Optimisation (AEO) Matters for SEO

Answer engines are where a growing share of queries get resolved without a click to a website. Brands that appear in AI answers build trust and authority at scale, even in zero-click searches. AEO is not a replacement for SEO, it builds on the same signals of authority, relevance, and technical health.

## How Answer Engine Optimisation (AEO) Works

AI systems extract answers from pages that clearly and directly address specific questions. Content formatted as Q&A with H2/H3 questions and immediate answers performs better. E-E-A-T signals and schema markup (FAQ, HowTo, DefinedTerm) make content more trustworthy and machine-readable.

## Common Mistakes

- Writing for human readers only, AI systems extract content differently to how people read it
- Burying the answer, the direct response should come in the first 1-2 sentences of each section
- Treating AEO as a separate strategy, it's the same content, structured better
