AEO vs SEO
Search is evolving. Traditional SEO optimises for ranked links. Answer Engine Optimisation optimises for the answer itself — the single recommendation AI tools give your customers.
What is SEO?
Search Engine Optimisation (SEO) is the practice of improving your website so it ranks higher in search engine results pages — the familiar list of blue links you see on Google, Bing and other search engines.
The goal is visibility: appearing on page one, ideally in the top three positions, for the keywords your customers search. SEO has been the backbone of digital marketing for over two decades, and it remains essential.
Core SEO disciplines
- Keyword research & targeting
- On-page optimisation
- Technical SEO & site speed
- Link building & authority
- Content strategy
- Local SEO
What is AEO?
Answer Engine Optimisation (AEO) is the practice of making your brand the answer that AI search tools — ChatGPT, Google AI Overviews, Perplexity, Gemini and Claude — recommend when customers ask questions.
Instead of competing for a position in a list of links, AEO targets the single citation, summary or recommendation the AI generates. When someone asks "What's the best project management software for construction?" or "Recommend a family lawyer in Perth," AEO ensures your brand is the name that comes back.
Core AEO disciplines
- Entity & knowledge graph presence
- Structured data & schema markup
- Answer-first content architecture
- Retrieval-ready site structure
- Citation & reference optimisation
- Trust signal engineering
SEO vs AEO — side by side
The two disciplines share DNA but optimise for different outcomes. Here's how they compare across the key dimensions that matter for your business.
Rank higher in search results for target keywords
Be cited as the answer inside AI-generated responses
Google, Bing, Yahoo — traditional search engines
ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews
Keyword rankings, organic traffic, click-through rate
Citations, share-of-voice in AI answers, referral traffic
Comprehensive pages that satisfy search intent
Clear, extractable answers with supporting context
Crawlability, indexation, page speed, mobile UX
Retrievability, chunking, schema, entity relationships
Backlinks, domain authority, referring domains
Entity recognition, knowledge panels, brand mentions, trust
What SEO and AEO share
AEO doesn't replace SEO — it builds on it. Many of the same signals that help you rank in Google also help AI models understand, trust and cite your brand.
High-quality, authoritative content
Fast, mobile-friendly site performance
Clear site architecture and internal linking
Trust signals (reviews, credentials, security)
Brand mentions and digital PR
Structured data implementation
If your SEO foundations are strong, you have a head start in AEO. The difference is in how you structure and present that authority so AI can confidently reference you as the answer.
What sets AEO apart
These are the techniques that make a meaningful difference in AI visibility but aren't traditionally emphasised in standard SEO practice.
Entity-first strategy
Building your brand as a recognised entity in knowledge graphs and LLM training data, not just a collection of optimised pages.
Answer architecture
Structuring content so the most important answer appears early, clearly, and in a format models can extract and paraphrase.
Retrieval optimisation
Designing page structure, headings and schema so AI retrievers surface the right passage for the right question.
Citation engineering
Ensuring your brand is referenced consistently and accurately across the web, so models learn to associate your name with your expertise.
LLM-specific content
Creating content that directly addresses the questions people ask AI tools, not just the keywords they type into search bars.
Trust signal density
Concentrating credibility markers — credentials, case studies, third-party validation — in ways models weigh heavily.
The search landscape is shifting — fast.
AI search is growing rapidly
Millions of users now turn to ChatGPT, Perplexity and Gemini for recommendations instead of scrolling through pages of search results. Google itself has introduced AI Overviews, synthesising answers directly into the SERP. The businesses that appear in these answers gain visibility without needing the top-ranked link.
Ranking alone is no longer enough
Even if you rank #1 in traditional Google results, you may not be cited in the AI-generated summary that appears above the fold. AEO closes that gap by making your content the source AI models trust and reference when they compose answers.
The brands that win in the next era of search won't just be the ones that rank highest. They'll be the ones AI understands, trusts and recommends.
