Answer Engine Optimisation is the practice of structuring your website, reviews and outside mentions so AI tools confidently recommend you when customers ask in their own words. It is a different discipline from Google search optimisation, with different signals and a different success metric.
The way Australian customers find and choose service businesses is changing. A growing share of buying decisions now start with an AI tool — not a Google search.
Someone needs an accountant, a tradesperson, a consultant, or a financial planner. Instead of scrolling through search results, they ask ChatGPT or Perplexity to recommend one. The AI tool gives them a name or two. They contact those businesses.
If your business is not set up to be recommended by those tools, you are invisible in that channel — regardless of how strong your Google ranking is.
That gap is what Answer Engine Optimisation addresses.
What is AEO?
AEO — Answer Engine Optimisation — is the practice of structuring your website, your reviews and your mentions on other websites so that AI tools can confidently recommend your business when customers ask in their own words.
Think of it like the difference between being listed in the phone book (Google search) and being the person a trusted friend recommends when someone asks "do you know a good accountant?"
AI tools are the trusted friend. AEO is the work you do to become the business they recommend.
The goal is not a ranking on a results page. The goal is being named when someone asks for help in your field.
How is AEO different from what most businesses already do for Google?
The two overlap on basic website quality, but they diverge on almost everything else.
What each one produces:
- Google optimisation → your website appears on a results page. The user chooses whether to click.
- AEO → you get named in a single AI answer. The AI has already chosen.
What each one rewards:
- Google rewards: how often your keywords appear on your pages, how many other websites link to you, how fast your pages load.
- AEO rewards: how clearly your website explains who you are, how many credible outside sources confirm you exist, whether your content is written in question-and-answer format, and whether your website has background identity code.
How you test each one:
- Google: check where you rank on the results page for specific search terms.
- AEO: run customer-language queries across each AI tool and note whether you appear as recommended, mentioned, or missing.
What success looks like:
- Google success: clicks from a results page.
- AEO success: being named in a recommendation.
Both are worth investing in. They target different channels and work in different ways.
Which AI tools matter for Australian small businesses?
Six AI tools are relevant for Australian buyers right now.
ChatGPT is the most widely used AI tool in Australia and the one most customers default to when asking for a recommendation. For most businesses, this is the most important tool to be visible on.
Perplexity checks live websites rather than relying entirely on what it was originally trained on. Changes you make today can show up in Perplexity results within days or weeks — faster than most other tools.
Gemini is Google's AI tool. It connects directly to your Google Business Profile (the listing that shows up in Google Maps and local search), your reviews, and your location data. If your Google presence is strong, Gemini often reflects that.
Claude is made by Anthropic and is growing fast among professionals, consultants and corporate buyers. It tends toward careful, considered answers rather than fast recommendations.
Grok is X's (formerly Twitter's) AI tool. Its users skew toward certain demographics. It is less universally relevant for Australian small businesses right now, but worth knowing about.
DeepSeek is free to use, which drives adoption. It is growing across Asia-Pacific and worth including if you want a thorough test.
What five signals do these tools actually use?
1. How clearly your website explains who you are
The main headline at the top of your homepage is the first thing AI tools read. If it says something vague — "Welcome to Smith & Co" or "Your trusted partner" — the tool has nothing to work with.
It needs to know: who you are, what you do specifically, who you serve, and where (if location matters). This is the most common reason businesses are invisible to AI tools. The fix is free and takes an afternoon.
2. Background identity code on your website
Schema markup (say it: "SKEE-muh") is background code that tells AI tools, in their own machine language, exactly what your business is. Think of it like the nutritional label on the back of a food packet — designed not for shoppers, but for systems that need precise structured information.
Without it, AI tools have to guess who you are from reading your visible content. With it, you give them a confirmed, structured description. The most important types for small businesses are business identity code, location code (if relevant), services code, and FAQ code.
3. A guide file for AI tools
An llms.txt file (say it: "L-L-M-S dot text") is a simple text file on your website that tells AI tools which pages are most important and how to interpret your content. Think of it as leaving a note for a new employee: "the important folders are these three, ignore the rest."
Writing one takes about 30 minutes. The format guide is at llmstxt.org. The vast majority of Australian small business websites do not have one.
4. Outside mentions and reviews
AI tools do not rely only on your own website. They look for confirmation from other sources — the same way you might trust a friend's recommendation more if multiple friends said the same thing.
Google reviews, industry directory listings, mentions in local media or professional association websites all function as trust signals. Businesses with no outside presence beyond their own website are harder for AI tools to recommend confidently.
5. Question-and-answer content
AI tools produce answers in question-and-answer format. When your website already has content in that same format — a FAQ section, articles with question-led headings — the tools can pull it directly into their answers.
A services page and a homepage are not enough. They tell the tool you exist. They do not give it anything specific to quote when recommending you.
How long does AEO take to work?
The honest answer: it depends on what you are fixing.
Technical fixes — adding background code, writing a guide file, publishing a FAQ section — can show up in AI tool responses within days to a few weeks. Perplexity in particular checks live websites, so changes can surface there quickly.
Trust signals take longer. Building a pattern of recent, specific Google reviews takes months. Earning credible mentions on other websites takes months. These signals compound over time — businesses that start early and stay consistent see the largest gains.
A practical benchmark: most businesses that fix the top two or three issues see a measurable improvement within 30 to 60 days. Full results across all five signals is a six-to-twelve-month investment.
Four mistakes Australian businesses commonly make
Treating it like Google search with a new name. The signals are different. Keyword density does not move your AEO results. Clear identity and outside confirmation do. Applying Google logic to an AEO problem wastes time.
Trying to game it. AI tools are trained on a huge amount of internet content and are good at identifying manipulative patterns. Fake reviews, keyword stuffing, and bulk directory submissions do not help — and can hurt. The signals that work are genuine.
Stopping after one or two fixes. One fix makes a small difference. Five well-executed fixes across identity, background code, trust, and content make a significant difference. Partial work is the most common reason businesses do not see results.
Buying generic directory listings in bulk. A listing in a relevant industry directory — an accounting body, a trades association, a professional body — carries real weight. Fifty generic listings that exist only to create web references carry almost none.
Three things you can do today
Write a guide file for AI tools. List your key pages, describe what each one is for, and place the file at yoursite.com/llms.txt. The format guide is at llmstxt.org.
Add a FAQ section to your website. Write five to ten questions in customer language and answer each one directly. This gives AI tools something specific to pull into their recommendations.
Claim and complete your Google Business Profile. If you serve a local area, a complete and active Google Business Profile is a trust signal that Gemini reads directly. Fill in every field. Respond to reviews. Keep your hours and contact details current.
Is AEO worth your time?
AEO is most valuable for service businesses where customers ask AI tools for recommendations: professional services, trades, health, finance, legal, hospitality. If your customers are already asking "who should I use for X" — and they are, in growing numbers — you need to be the answer.
It is less urgent for businesses with formal procurement processes, where buying decisions involve tenders or RFPs, or for very early-stage businesses where establishing the basics comes first.
If you are not sure whether your customers are using AI tools in your field, the right move is to test. Run the five queries described in this article and see what comes back. That tells you whether the channel is active before you invest time fixing it.
Frequently asked questions
What is the difference between AEO and SEO?
SEO stands for Search Engine Optimisation — it helps you rank on a Google results page so users click through to your website. AEO stands for Answer Engine Optimisation — it helps AI tools name and recommend you directly in their answers. The two overlap on basic website quality but diverge on trust signals, background code specifics, and the question-led content format AI tools prefer. Both are worth doing. They target different channels.
Will AEO replace SEO?
Not entirely, and not soon. Google still drives a large share of web traffic. What is changing is that a growing portion of buying decisions start with an AI tool — particularly for service businesses where customers want a recommendation rather than a list of links. AEO addresses that channel. SEO addresses traditional search. A well-structured website serves both.
Do I need to hire someone to do AEO?
Not necessarily. The foundational fixes — a guide file, a FAQ section, a clear homepage headline, and basic background code — are within reach for most business owners or their existing web developer. Many businesses make meaningful progress without hiring anyone new.
How do I measure AEO success?
Run the same test queries across the same AI tools at regular intervals and track whether you move from missing to mentioned to recommended. A monthly cadence works when you are actively making changes. A quarterly check is enough once things have stabilised.
Is AEO different in Australia compared to the US?
The underlying approach is the same globally. The practical differences are spelling (Australian English, not American), the sources AI tools treat as credible for Australian queries (Australian directories, local media, professional associations), and the specific tools that see the most Australian usage. The approach applies equally worldwide; the execution details are Australian-specific.
