Quick answer
SEO aims to rank your pages in search results so people click through. AEO (answer engine optimisation) aims to make your content the direct answer in featured snippets, AI Overviews, voice assistants and tools like ChatGPT. You need both: SEO earns visibility and trust, while AEO makes your content easy for machines to quote.
Last updated: November 2026
Search has changed. People still type queries into Google, but increasingly they get an answer without clicking: a featured snippet, an AI Overview, a voice reply or a chatbot summary. That shift has created a new acronym, AEO, and plenty of confusion about whether it replaces SEO.
It does not. AEO is best understood as an extension of good SEO, with a stronger focus on clear answers, structured content and being cited by AI systems.
This guide explains what each discipline is, how they differ, where they overlap, and how a UK business can split its time and budget sensibly between them.

What SEO is
Search engine optimisation is the practice of improving your website so that it appears higher in organic search results. It covers technical health, on-page content, links and, for local businesses, your Google Business Profile and reviews.
The traditional goal is a click: a user sees your result, visits your site and takes an action. Success is typically measured by rankings, organic traffic and the leads or sales that follow.
What AEO is
Answer engine optimisation is the practice of structuring your content so that search engines and AI assistants can extract and present it as a direct answer. That includes featured snippets, People Also Ask boxes, AI Overviews, voice search answers and chat-based assistants such as ChatGPT, Gemini and Perplexity.
The goal is to be the source that is quoted or recommended, whether or not the user clicks. Success is measured by being cited, by brand mentions in AI answers, by snippet ownership and by the downstream effect on branded searches and enquiries.
Key differences in approach
- Format: SEO pages can be long and varied; AEO content needs direct, concise answers near the top, followed by detail.
- Structure: AEO relies heavily on clear headings, lists, tables, FAQ sections and schema markup to make facts easy to extract.
- Authority: both depend on trust, but AEO places extra weight on being a clear, consistent entity that is mentioned across reputable sources.
- Measurement: SEO tracks rankings and clicks; AEO tracks citations, snippets and brand visibility inside AI answers.
- Query focus: AEO leans towards question-style queries such as “how”, “what” and “which”.
Where they overlap
Most AEO tactics are simply good SEO done with extra care. Both need accurate, helpful content written for people, a technically sound site, strong E-E-A-T signals (experience, expertise, authoritativeness and trust) and good internal linking.
If your SEO foundations are weak, AEO will not rescue you. AI systems tend to draw from pages that already rank, are crawlable and are trusted. That is why we recommend fixing technical and on-page basics first, then layering answer-focused structure on top. Our on-page SEO service does both in one workflow.
How to write for AEO
Start each page or section with a direct answer to the question it addresses, in two or three sentences. Then expand with detail, examples and evidence. This “answer first” format helps both readers and machines.
Use question-style headings that mirror real queries, such as “How much does SEO cost in the UK?” followed immediately by the answer. Keep paragraphs short, define terms clearly, and use lists and tables where they make information easier to scan.
Add an FAQ section to key pages and mark it up with FAQPage schema where appropriate. Make sure facts, prices, dates and names are accurate and consistent across your website, because AI systems are more likely to quote clear, consistent sources.
Technical and entity signals that help both
- Fast, crawlable pages with clean HTML, descriptive headings and logical structure.
- Schema markup for organisation, local business, articles, FAQs and products where relevant.
- A consistent brand name, description and contact details across your website, social profiles and directories.
- Author information and credentials that demonstrate real expertise.
- Citations from reputable sites, which reinforce that you are a trusted source.
Think of this as helping machines answer the question “who is this business and why should I trust it?” with confidence.
An example: one page written for SEO and AEO
Take a UK accountancy firm writing about “How much does an accountant cost for a small business?”. An SEO-only version might open with a long introduction about the importance of accounting and bury the pricing halfway down. An SEO and AEO version opens with a two-sentence answer: typical monthly fees by business size, followed by what is included and what changes the price.
Below that sit short sections for sole traders, limited companies and VAT-registered businesses, each with a clear range and a note on what affects the cost. A comparison table sets out the common services, and an FAQ answers questions such as “Is a fixed fee better than hourly?”.
This layout still ranks well for the classic keyword, but it also gives Google a clean block to use as a snippet and an AI assistant a clear passage to quote. The page earns its place in both worlds without separate content.
Notice that none of this requires gimmicks. It simply demands that you know the answer, state it plainly and back it up. Businesses that do this consistently across their key pages tend to be the ones that get named when AI tools recommend providers.
How AEO and SEO results differ in practice
A page can rank in the top three and not be cited by an AI Overview, or be cited without ranking first. Studies of AI Overviews suggest sources often come from a mix of top-ranking pages and pages that answer a specific part of the query clearly.
AEO can also reduce clicks even as visibility grows, which is why it is important to measure brand searches, direct visits and enquiries as well as traffic. Being named as the recommended option in an AI answer can drive high-intent visitors who arrive already convinced.
How to split your effort
For most UK small and mid-sized businesses, a sensible starting split is to put around 70 percent of effort into core SEO, covering technical health, service pages, local SEO and links, and around 30 percent into AEO and GEO tactics such as answer-first content, schema and mentions. As your foundations mature, the proportions can shift.
If you are starting from scratch, begin with a website SEO audit to identify technical and content gaps, then prioritise pages that already rank on page two, because small improvements can turn them into snippets and citations.

Frequently asked questions
Is AEO replacing SEO?
No. AEO builds on SEO. Strong SEO foundations make it more likely that AI systems will find, trust and cite your content.
What is the difference between AEO and GEO?
AEO focuses on being the direct answer in search features and voice assistants. GEO (generative engine optimisation) focuses on being cited and recommended inside generative AI tools such as ChatGPT and Perplexity. They overlap heavily.
Do I need schema markup for AEO?
It is not mandatory, but structured data helps machines understand your content and can improve eligibility for rich results and extraction.
How do I measure AEO success?
Track featured snippets, appearances in AI Overviews, mentions in AI assistants, branded search growth and enquiries, alongside traditional rankings and traffic.
