SEO and Answer Engine Optimisation (AEO): What’s Changed in 2026?
Search is changing faster than ever.
For years, businesses focused on Search Engine Optimisation (SEO) to improve their rankings in Google. Today, customers are also asking questions in Google AI Overviews, ChatGPT, Gemini, Claude, and Perplexity, often expecting instant answers instead of scrolling through a list of websites.
Does that mean SEO is becoming obsolete?
Not at all.
SEO continues to form the basis of online visibility, although the difference now is that companies also need Answer Engine Optimisation (AEO) so that search engines and AI platforms can understand, trust, and recommend their content.
SEO enables people to find your website, and AEO makes your website the answer.
In this guide we are going to look at how SEO and AEO work in conjunction with each other, examine the changes that have taken place in 2026, and show you how your business can remain visible no matter where customers are searching.
What Are SEO and AEO?
A Simple Definition
SEO consists of making your website better so that it achieves a good position in search engines such as Google.
Answer Engine Optimisation (AEO) builds on SEO by structuring your content so search engines and AI-powered platforms can easily understand it and use it to answer users’ questions.
Together, SEO and AEO help your business become more discoverable across both traditional search results and AI-powered search experiences.
How SEO and AEO Work Together
Although Google uses hundreds of ranking signals, the foundations of online visibility remain consistent.
Effective SEO and AEO rely on:
- Helpful, relevant content
- Content that answers real customer questions
- Keywords aligned with search intent
- Strong technical SEO
- Website speed and mobile usability
- High-quality backlinks
- Structured data (Schema Markup)
- Positive user experience
- Clear content structure
- Demonstrated expertise and trust
If these factors work in unison, your website will have a better chance of ranking highly in Google and of being mentioned in AI-generated answers.
What Are Answer Engines?
Answer engines use artificial intelligence to understand questions and give direct responses based on trusted information.
Instead of searching for: “SEO agency Sydney”
People now ask: “Who’s the best SEO agency for business in Sydney?”
Instead of just showing websites, answer engines understand the question, gather relevant information, and then produce a conversational response.
Examples include:
- Google AI Overviews
- ChatGPT
- Gemini
- Claude
- Perplexity
This is where Answer Engine Optimisation (AEO) becomes increasingly important.
Why AEO Matters
Traditional SEO focuses on helping your website appear in search results.
AEO focuses on making your content easy for AI systems to understand, reference, and recommend.
Businesses that invest in both are better positioned to be found across:
- Google Search
- Google AI Overviews
- ChatGPT
- Gemini
- Claude
- Perplexity
- Voice assistants
Rather than separate strategies, SEO and AEO are complementary.
What’s Changed in Search in 2026?
Customer behaviour has shifted significantly.
Search Is Becoming More Conversational
People now ask complete questions instead of typing short keyword phrases.
Instead of: “SEO agency Sydney”
They ask: “Who’s the best SEO agency for business in Sydney?”
Content that answers these questions naturally is more likely to perform well in both Google Search and AI-powered search.
AI-Generated Answers Are Becoming Common
Google AI Overviews and AI assistants increasingly provide answers directly within search results.
That means businesses need content that’s easy to understand, well-structured, and genuinely helpful.
Trust Matters More Than Ever
Google and AI platforms both reward websites that demonstrate:
- Experience
- Expertise
- Authoritativeness
- Trustworthiness (EEAT)
They also consider:
- Customer reviews
- Backlinks
- Brand mentions
- Consistent business information
- Technical website quality
Visibility Extends Beyond Google
People no longer depend solely on Google Search.
They also use:
- Google AI Overviews
- ChatGPT
- Gemini
- Claude
- Perplexity
Being visible wherever customers search has become an essential part of digital marketing.
Does SEO and AEO still matter?
Absolutely. More than ever.
SEO establishes the technical and content base that enables search engines to understand your website.
Building on that foundation, AEO makes it easier for AI platforms to reference and recommend your content.
SEO Builds
- Website authority
- Helpful content
- Technical quality
- Trust
- Search visibility
AEO Supports
- AI-generated answers
- Direct responses

The stronger your SEO, the more effective your AEO becomes.
