Answer engine optimisation (AEO) is the practice of structuring your business information and content so AI systems can quote it directly, instead of only ranking your website in a list of links. The target is the answer itself: the response ChatGPT gives, the summary in Google’s AI Overviews, the citation Perplexity displays, the reply a voice assistant reads out. Where search engine optimisation competes for a position, AEO competes to be the source.
This guide covers what AEO actually involves, how it differs from SEO and GEO, which businesses it suits, what it costs in Australia, and how to tell whether you need it.
Key takeaways
- AEO changes the unit of success from a ranked link to a quoted answer.
- It shares most of its inputs with SEO. It is an emphasis shift rather than a separate discipline.
- Google states its standard SEO guidance applies to its AI features and no special markup is required.
- The highest-leverage work is off your website: profiles, citations, reviews and independent mentions.
- Some businesses genuinely do not need it yet. There is a section below on who.
How does AEO work?
AEO works by making your business easy for a machine to describe accurately and confidently. That means three things: publishing direct, quotable answers to the questions your customers ask, keeping your business details identical across every source that describes you, and earning independent corroboration through reviews, directories and mentions. When those agree, an AI system has enough evidence to name you.
The mechanism is worth understanding, because it explains why the tactics look the way they do. An AI answer is assembled rather than retrieved. The system gathers material from several sources, reconciles the contradictions and writes a response. Your job is to reduce the contradictions and supply material that survives being lifted out of context.
How is AEO different from SEO?
| SEO | AEO | |
|---|---|---|
| Target | A ranked position in a results list | A quoted answer or a named recommendation |
| Success looks like | A click to your site | A citation, a mention, or a direct enquiry |
| Content that wins | Comprehensive pages | Short standalone answers within good pages |
| Key off-site lever | Backlinks | Citations, reviews and mentions |
| Measurement | Rankings, clicks, impressions | Mention rate, citations, AI referral traffic |
| Where it happens | Google and Bing results pages | ChatGPT, Gemini, Perplexity, Copilot, AI Overviews |
The overlap is substantial and deliberate. Google has stated that its standard SEO best practices apply to AI Overviews and AI Mode, with no additional structured data requirement, in its AI features documentation. Treat AEO as a set of habits layered onto competent SEO rather than a replacement for it.
What does AEO actually involve?
Six workstreams, in the order they usually deliver.
Entity accuracy. Your business name, address, phone, services and service areas identical across your website, Google Business Profile, directories and association listings. Contradictions are the most common cause of invisibility.
Google Business Profile completeness. Every field, every service with a description, service areas, photos and the questions and answers section. This is the densest source of structured facts about your business that exists.
Review specificity. Reviews that name the job and the suburb, generated continuously rather than in campaigns.
Answer-led content. Service pages and articles that open with a direct answer, use question-led headings, and include short passages that make sense when quoted alone.
Structured data. Organization, LocalBusiness and FAQPage markup that reflects content actually visible on the page.
Independent mentions. Association registers, trade media, local coverage and genuine community presence.
Our guide to local business AEO covers the first three and the last one in detail.
How much does AEO cost in Australia?
Australian agencies typically deliver AEO either as an addition to an existing SEO retainer or as a standalone engagement. Foundation work, covering profile completion, citation cleanup and structured data, is usually a fixed-scope project. Ongoing work covering content, mention building and monthly visibility testing runs as a monthly retainer. Cost scales with the number of locations and service lines, since each one multiplies the prompt set and the citation footprint.

What moves the number:
| Factor | Effect on cost |
|---|---|
| Number of locations | Each city multiplies the prompt set and citation work |
| Number of service lines | Each needs its own answer-led page and testing |
| Current profile and citation state | A neglected footprint takes longer to correct |
| Competitiveness of the category | More effort required to displace an incumbent |
| Whether SEO is already running | Substantial overlap reduces incremental cost |
A warning worth heeding. If a provider quotes AEO as a fixed monthly fee with no audit, no defined prompt set and no stated measurement method, ask what they are actually doing. The category has attracted vendors selling schema files and a dashboard.
Which businesses need AEO?
Local service businesses where customers ask for recommendations. Trades, installers, clinics, firms, agencies. The query “who is the best X in Y” is exactly what these systems answer, and being named is the whole game.
High-consideration purchases where buyers research for weeks before enquiring. Solar, legal, medical, financial services, commercial equipment. AI assistants are used heavily in the research phase, well before a shortlist forms.
Businesses already losing informational traffic. If your blog traffic has fallen while your rankings held, answers are being resolved without a click. Our article on why website traffic is dropping after LLMs covers the pattern.
Businesses with a reputation problem in AI answers. Where an assistant describes you inaccurately or names a competitor for work you do.
Which businesses do not need AEO yet?
Being straight about this matters more than the leads it costs.
Businesses with no working website or Google Business Profile. Fix the foundations. AEO layers onto competent basics and cannot substitute for them.
Businesses whose customers do not research online. Some trade and wholesale relationships run entirely on referral and repeat contact. If nobody is searching for your category, nobody is asking an AI about it either.
Businesses winning entirely on paid acquisition with healthy unit economics. AEO is worth adding for resilience, and it is not urgent while the paid channel performs.
Very early-stage businesses with no reviews, no listings and no history. There is nothing yet for a system to corroborate. Build the trading record first.
How do you know if AEO is working?
There is no rank tracker for AI answers. Measurement runs across five numbers in four places: mention rate against a fixed prompt set, citations in Bing Webmaster Tools, AI referral traffic in GA4, branded search lift in Search Console, and self-reported attribution on your enquiry form.
What we recommend
Start with an audit rather than a retainer. Run your buying questions through ChatGPT, Perplexity and Gemini in fresh sessions and record who gets named and which sources are cited. That fifteen-minute exercise tells you whether you have a visibility problem, an accuracy problem or no problem at all.
Our position, from the campaigns we run: for most Australian service businesses, correcting entity data across authoritative sources moves AI visibility faster than publishing content does. Content earns its return once the corroborating evidence exists. Any provider proposing a content-first AEO programme without auditing your profile and citations first has the sequence backwards.
Frequently asked questions
Is AEO the same as SEO?
They share most of their inputs and differ in target and measurement. SEO competes for a ranked link. AEO competes to be the source quoted inside an answer. Google states its standard SEO guidance applies to its AI features, so AEO is best understood as an emphasis shift layered onto competent SEO rather than a separate discipline.
Is AEO the same as GEO?
They overlap heavily and many practitioners use the terms interchangeably. The useful distinction is that AEO targets your content being quoted as a source, while generative engine optimisation targets your business being named as a recommendation. Local service businesses usually care more about the second.
Do I need special schema markup for AEO?
No. Google states there is no additional structured data requirement for AI Overviews or AI Mode beyond its standard guidance. Structured data still helps machines parse your page accurately, so use markup that genuinely reflects visible content. Anyone selling schema alone as an AEO service is charging for very little.
How long does AEO take to work?
Profile and citation corrections can influence tools that run live web searches within weeks. Review volume and independent mentions build over one to three months. Treat it as ongoing practice with monthly testing rather than a project with an end date.
Can I do AEO myself?
Most of the foundations, yes. Completing your Google Business Profile, correcting citations, asking customers for specific reviews and running monthly prompt tests need time rather than technical skill. Businesses usually bring in help for structured data, answer-led content at scale, mention building, or when they serve multiple cities.
Does AEO replace SEO?
No. AI systems read search results, directories and review platforms. A site that is slow, unindexed or thin gives them nothing to work with. AEO sits on top of SEO foundations rather than replacing them, and the two share most of the same work.
