To optimise for AI search (AEO), give each page a concise quick answer, use question-based headings, write clear factual content with definitions and sources, add structured data, and get the technical trust basics right (HTTPS, speed, accessibility). This makes your pages easy for AI to find, parse, trust and quote.
AI Engine Optimisation (AEO) is the practice of making your content easy for AI assistants to retrieve and cite. It builds on SEO and adds a focus on self-contained answers, structure, entities and demonstrable trust. This is the definitive playbook covering every lever.

For business owners
AEO future-proofs your visibility. As more customers ask AI instead of searching, the sites that are structured and trustworthy enough to be cited win attention that competitors lose. Because AEO reuses your existing SEO and trust investments, it is high leverage rather than a whole new workload.
How it works (technical)
The AEO playbook:
- Quick answers — a 40–60 word direct answer near the top of each page.
- Question headings — phrase H2/H3s as the questions users ask.
- Chunkable structure — self-contained sections, bullet summaries, definitions and comparison tables.
- Structured data — Article, FAQPage, HowTo, BreadcrumbList and Organization schema.
- Entities — consistent names, author/organisation info, and links to authoritative references.
- Technical trust — HTTPS, Core Web Vitals, mobile, accessibility and crawlability, including allowing reputable AI crawlers.
Then measure: ask the major assistants your target questions and see who gets cited.
Real-world example
A cybersecurity blog restructured its top articles with quick answers, FAQ schema and question headings, and fixed HTTPS and speed issues. Within weeks its pages started appearing as citations in Perplexity and AI Overviews for its core questions — visibility it had never captured through classic ranking alone.
Why it matters
AEO is how you stay visible as search becomes answer-led. Every lever here is measurable, and the technical trust portion is exactly what Plexa Trust scans for.
How to fix it
Add a concise quick-answer paragraph near the top of each key page.
Rewrite headings as the natural questions people ask.
Break content into self-contained, quotable sections with bullets and definitions.
Implement Article, FAQPage, HowTo and Organization structured data.
Fix technical trust: HTTPS, speed, accessibility, crawlability and AI crawler access.
Best practices
Answer the question first, then elaborate — inverted-pyramid style.
Keep facts current, specific and attributable.
Reuse your SEO and schema work rather than building AEO separately.
Common mistakes
Keyword-stuffing instead of writing clear, quotable answers.
Skipping structured data that helps machines understand pages.
Neglecting the technical trust baseline that gates retrieval.
Frequently asked questions
What is AEO?
AEO (Answer or AI Engine Optimisation) is optimising content so AI assistants can find, understand, trust and cite it. It extends SEO with a focus on clear answers, structure and trust.
Is AEO the same as GEO?
Largely yes. GEO (Generative Engine Optimisation) is another name for the same goal: being surfaced and cited by generative AI answer engines.
What is the single most important AEO tactic?
A clear, self-contained quick answer near the top of the page, backed by trustworthy content and a secure, fast site.
Does structured data guarantee citations?
No, but it significantly helps machines interpret your content accurately, improving your chances of being understood and quoted.
How do I let AI crawlers access my site?
Ensure robots.txt does not block reputable AI user-agents you want to allow, and keep pages crawlable and fast so they can be retrieved.
How do I measure AEO success?
Ask the major AI assistants your target questions and track whether and how often your site is cited, alongside traditional search metrics.
Do I need new content for AEO?
Often you can retrofit existing content with quick answers, question headings and schema rather than writing from scratch.
Will AEO hurt my Google rankings?
No. AEO best practices — clarity, structure, trust, speed — also help classic SEO, so the two reinforce each other.
