There's a position on Google that ranks above number one. It appears before the paid ads, before the organic results, and it captures a disproportionate share of clicks, trust, and traffic. It's called Position Zero — the featured snippet — and winning it is the goal of Answer Engine Optimisation.
But AEO goes further than just featured snippets. It's the practice of structuring your content to answer questions directly, across every format that modern search engines use to respond to queries: featured snippets, People Also Ask boxes, Google's AI Overviews, voice search, and AI assistant responses.
As search becomes increasingly answer-oriented, AEO is becoming one of the most important visibility disciplines for any business that wants to be found.
What is Answer Engine Optimisation?
Answer Engine Optimisation (AEO) is the practice of formatting, structuring, and optimising your content so that search engines and AI tools serve it as the direct answer to a user's question.
The name comes from the observation that search engines are increasingly functioning as "answer engines" — not just returning a list of links, but directly answering the question. Google's featured snippets, People Also Ask results, and AI Overviews are all examples of this. So are the responses you get from Siri, Alexa, or Google Assistant when you ask a voice query.
AEO is about making sure that when the search engine or AI tool answers the question, it uses your content to do so.
The different types of answer placements
Featured snippets (Position Zero)
Featured snippets appear at the top of Google's results, above all organic links. They pull a specific section of content from a webpage and display it directly in the results — a paragraph, a list, a table, or a video. They're called "Position Zero" because they appear before the number-one result.
Winning a featured snippet typically increases click-through rate significantly, and for voice searches, the featured snippet is almost always the only result read aloud.
People Also Ask (PAA) boxes
People Also Ask boxes are expandable question-and-answer sections that appear throughout Google's results. Each time someone expands one, Google adds more related questions. Being the answer to PAA questions increases your visibility across a wide range of related queries.
AI Overviews
Google's AI Overviews (formerly Search Generative Experience) generate AI-written summaries at the top of results for many searches. They pull content from multiple sources and synthesise it into a coherent answer — with citations. Getting cited in AI Overviews is a major AEO goal.
Voice search
When someone asks Google Assistant, Siri, or Alexa a question, they typically get one answer — usually the featured snippet or top result. As smart speaker and voice search usage continues to grow, appearing in these answer slots becomes increasingly valuable.
How does AEO differ from SEO?
Traditional SEO focuses on ranking in the list of blue links — getting your page to appear in the top ten results for a keyword. AEO focuses on appearing above those results, in the answer box or snippet that sits at the very top of the page.
The key differences in approach:
- Intent focus — AEO targets question-based queries specifically ("what is", "how to", "why does", "best way to"), not just keyword phrases
- Content structure — AEO content is formatted to directly answer questions clearly and concisely, with the answer near the top of the section
- Schema markup — AEO heavily uses FAQ schema, HowTo schema, and other structured data to help search engines understand your content
- Brevity and clarity — while long-form content is great for SEO, AEO requires the key answer to be distilled into a concise, direct response
The anatomy of an AEO-optimised page
A well-optimised page for AEO typically includes:
- A clear question as a heading — use the exact question your audience is asking as an H2 or H3
- A direct, concise answer immediately following — 40–60 words is the sweet spot for paragraph snippets
- Supporting detail below — expand on the answer for readers who want more depth
- FAQ sections — a dedicated FAQ section with structured markup is one of the fastest ways to capture PAA positions
- Lists and tables where appropriate — Google often pulls list-format content into featured snippets
Does AEO work for small businesses?
Absolutely — and this is one of AEO's great levellers. Featured snippets and PAA answers don't always go to the biggest brands or the highest-authority domains. They go to the page that best answers the specific question.
A small Melbourne accounting firm with a well-structured answer to "what expenses can I claim as a sole trader" can outrank a Big Four accounting website in the featured snippet, because they answered that specific question more clearly and directly.
This is why AEO is particularly powerful for niche businesses, service professionals, and anyone with genuine expertise in a specific area.
AEO and GEO: stronger together
AEO and GEO are complementary disciplines. The content structures that help you win Google's featured snippets — clear questions, direct answers, structured formatting — are the same structures that help AI models understand and cite your content.
At SearchShift, we treat AEO and GEO as two sides of the same coin. Every piece of content we create is structured to perform across both — traditional answer boxes and AI-generated responses alike.

Getting started with AEO
The first step is identifying the questions your buyers are actually asking. Tools like Google's "People Also Ask" results, keyword research platforms, and your own customer conversations are all rich sources of question data.
From there, it's a matter of creating content that directly answers those questions — clearly, concisely, and with the right schema markup to help Google understand what you've written.
It's not complicated. But it does require a disciplined approach to content structure that most businesses haven't adopted yet. That gap is your opportunity.
