Ask ChatGPT “who are the best [your industry] providers in Sydney?” right now.
Is your business in the answer?
If it isn’t, you have a visibility problem that no amount of traditional SEO will fix on its own. A growing share of your customers never see a list of blue links at all. They ask a question, get a synthesised answer, and shortlist the handful of brands the AI mentions. Everyone else is invisible.
This guide is our complete GEO playbook for Australian businesses. It covers what generative engine optimisation actually is, why the Australian data says you can’t wait, how AI engines decide who gets cited, and the ten actions that measurably improve your AI visibility, including the 20-prompt audit we run for our own clients.
What is Generative Engine Optimisation (GEO)?
Generative Engine Optimisation is the discipline of making your brand and content easy for large language models (LLMs) to find, understand, trust and cite. The term comes from a 2024 research paper by academics at Princeton University, Georgia Tech and IIT Delhi, presented at the KDD 2024 conference, which showed that targeted content optimisation could lift a source’s visibility in AI-generated answers by up to 40%.
The goal shift is simple but profound:
- SEO: optimise a page, rank in a list of results, earn a click.
- GEO: optimise your brand’s entire digital footprint, get cited or recommended inside the AI’s answer, earn trust before the click ever happens.
You may also hear the terms AEO (Answer Engine Optimisation), LLM SEO or AI search optimisation. The industry hasn’t settled on one label, and the tactics overlap heavily, but the destination is the same. When an AI answers a question in your category, your business is part of that answer.
Why Australian businesses can’t afford to wait
Australia is one of the fastest AI-adopting markets in the world, and the local numbers in 2026 tell a blunt story:
- 13.6 million Australians, or 58% of everyone aged 14 and over, used AI tools in an average four-week period, according to Roy Morgan’s March 2026 quarter research. ChatGPT alone reached 10.5 million Australian users.
- Usage is heaviest among 25 to 49 year olds, the exact cohort making household and B2B purchasing decisions, not just students experimenting.
- 12% of Australians now name AI tools as their primary way to find information online, up from 5% a year earlier (Telsyte, 2026).
- Google’s Australian search market share has slipped from roughly 94% in 2024 to the 88 to 91% range in 2026, while Bing, carried by Copilot, has nearly tripled its share.
- Google AI Overviews rolled out nationally in October 2024 and now appear on close to half of tracked queries globally, according to BrightEdge’s year-on-year analysis.
Layer on the global signals. Gartner forecasts a 25% decline in traditional search engine volume by the end of 2026, and HubSpot’s 2026 State of Marketing research found 44% of AI search users now treat it as their primary channel for product discovery. The conclusion is unavoidable. The buyer journey has grown a new front door, and most Australian businesses haven’t put their name on it.
Here is the part most companies miss. Ranking well on Google no longer guarantees AI visibility. Research from AI visibility firm Brandlight found the overlap between top Google results and AI-cited sources has fallen from around 70% to below 20%. AI engines are developing their own preferences about who to trust. That gap is what GEO closes.
How AI engines decide who to cite
When someone asks ChatGPT, Perplexity or Google’s AI Mode a question, three things happen.
1. Query fan-out
The AI doesn’t run your customer’s question as a single search. It breaks the question into multiple sub-queries. “What’s the best accessible web design agency for an Australian NFP?” might fan out into separate searches for accessible web design Australia, WCAG compliance agencies, and NFP website case studies. If your content targets only one phrasing of one keyword, you miss most of the fan-out.
2. Retrieval and ranking
The engine pulls candidate sources, weighing authority, topical relevance, entity clarity (does the AI actually understand who you are?) and freshness. Your traditional SEO foundation matters enormously here, because an uncrawlable, slow or thin site never makes the candidate pool.
3. Synthesis and citation
This is the step that separates GEO from SEO. The AI doesn’t point at your page. It rewrites it. The engine selects short, factual, extractable passages such as clear definitions, statistics, direct answers and attributable claims, then stitches them into a response, citing anywhere from two to seven sources. The Princeton research found this passage-level extractability is where the biggest gains live. Adding statistics lifted citation visibility by roughly 26%, quoted expert statements by around 28%, and cited sources by about 25%.
The practical takeaway: you need to be retrieved (technical signals), ranked (authority signals) and selected for synthesis (citable, structured content). Most Australian businesses invest in the first two and completely ignore the third.
GEO vs SEO vs AEO: what actually changes
| SEO | AEO | GEO | |
| Optimises for | Google & Bing rankings | Featured snippets, People Also Ask | AI answers across ChatGPT, AI Overviews, Gemini, Perplexity, Copilot |
| Unit of success | Position on a results page | Being the extracted answer | Citations, mentions and recommendations inside AI responses |
| Core levers | Keywords, backlinks, technical health | Question-led structure, concise answers, schema | Entity clarity, citable passages, third-party trust, AI crawler access |
| Measures | Rankings, clicks, organic traffic | Snippet ownership, PAA presence | Mention rate, citation share, AI referral traffic, answer sentiment |
They aren’t competing strategies. They are layers. SEO is the foundation, because AI engines still lean on search indexes for retrieval. AEO structures your answers. GEO extends your authority into the generative layer. Google’s Danny Sullivan put it plainly when he said “good SEO is good GEO.” If someone tells you SEO is dead, they are selling something. If someone tells you SEO alone is enough, they are behind.
The GEO playbook: 10 actions that move the needle
1. Open the gates: audit your AI crawler access
The most common GEO failure we see in Australian site audits is embarrassingly basic. The site is blocking AI crawlers without knowing it. Check your robots.txt for rules affecting GPTBot, OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot and Google-Extended. If you are on Cloudflare, check your settings, because it changed defaults to block AI bots and many businesses were switched off from AI search overnight without realising. Then check your server logs. If AI user agents aren’t visiting, nothing else in this playbook matters yet.
2. Lead with the answer, then earn the depth
Generative engines reward content that answers the question in the first 40 to 60 words, then expands. Restructure key pages so every major H2 opens with a direct, self-contained answer a machine could lift verbatim. Give the definition first and the nuance second. That answer-first structure is exactly why the quick-answer box sits at the top of this article.
3. Add statistics, expert quotes and cited sources
This is the highest-evidence tactic in the entire discipline. The Princeton KDD study found these three additions produced the largest citation lifts, each in the 25 to 28% range. Audit your ten most important pages. How many contain a verifiable statistic, a named expert statement, or a citation to a credible source? For most Australian SMB sites, the honest answer is zero. Fix that and you are already ahead of the majority of your competitors.
4. Implement schema, and consider llms.txt
Structured data is how you hand AI systems your facts on a plate. Priorities for Australian businesses are Organization, LocalBusiness (with your actual service areas), Article with author markup, FAQPage, and Product or Service schema where relevant. An emerging addition is llms.txt, a plain-text file that summarises your site for language models. It is not yet a universal standard, but it costs almost nothing to implement and early adopters are disproportionately represented in AI answers.
5. Make your entity unmistakable
AI engines think in entities: who you are, what you do, where you operate, who vouches for you. Inconsistent contact details, a vague About page, unnamed authors and conflicting descriptions across LinkedIn, directories and your own site all blur that entity. Tighten it. Use one consistent business description everywhere, name your team members with their credentials, and state your services and locations clearly. You want the model to be able to complete the sentence “…is a [what] in [where] known for [speciality]” without hesitation.
6. Publish something nobody else has
AI engines face a dozen near-identical articles on every topic. Original research, proprietary benchmarks, real case study data and first-hand experience give them a reason to cite you specifically. An Australian manufacturer publishing its own industry pricing benchmark, or an agency publishing real campaign performance data, becomes a primary source, and primary sources get cited on repeat. This is E-E-A-T taken literally: experience the model cannot find anywhere else.
7. Keep cornerstone content demonstrably fresh
AI engines weigh recency heavily. A 2024 guide with no updates loses citations to a maintained 2026 article on the same topic. Refresh your cornerstone pages quarterly, update the statistics, and display a visible “Last updated” date. Consistent publishing compounds, because brands that publish or refresh regularly build AI visibility far faster than occasional publishers.
8. Build your third-party footprint
Roughly half of what determines your AI visibility doesn’t live on your website. LLMs triangulate trust from reviews on Google Business Profile and industry platforms, from directories, earned media, industry associations, podcasts, and community discussions on Reddit and forums. When your brand appears consistently across independent sources, the model treats you as established fact rather than self-promotion. Digital PR is no longer just a link-building tactic. It is how you get written into the retrieval layer.
9. Localise for the Australian context
AI platforms favour locally relevant sources for locally framed questions. Use Australian English and terminology, state your service areas explicitly at suburb and city level rather than just “Australia-wide,” reference Australian pricing, regulations and standards, and publish Australian case studies. A page written for “Sydney NFPs navigating WCAG 2.2 compliance” will win Australian AI citations that a generic global page never will.
10. Measure it, or you’re guessing
Only a small minority of brands systematically track AI search performance, which makes measurement itself a competitive advantage. Track three things monthly. First, your mention rate across a fixed set of prompts, covered in the audit below. Second, your AI referral traffic in GA4, segmenting referrals from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com. Third, the accuracy and sentiment of how AI describes you. Tools like Ahrefs Brand Radar and Otterly can automate this at scale.
The 20-prompt AI visibility audit (do this today)
This is the exercise we run at the start of every GEO engagement, and you can run a basic version yourself in an hour.
- Write 20 prompts your real customers would ask. Split them across the funnel: five category questions (“what should an NFP look for in a web agency?”), five comparison questions (“best B2B marketing agencies in Sydney”), five problem questions (“why is my website invisible in ChatGPT?”) and five brand questions (“is [your business] reputable?”).
- Run every prompt through ChatGPT, Google (checking for AI Overviews), Perplexity and Gemini. Use fresh sessions so your history doesn’t skew results.
- Score each response. Were you mentioned? Cited as a source? Recommended? Described accurately? Which competitors appeared instead, and which websites were cited as sources?
- Map the gaps. The sources the AI does cite for your money questions are your GEO target list. Those are the pages to outdo and the platforms where you need presence.
- Re-run the same 20 prompts monthly. Your mention rate over time is your core GEO KPI.
Most businesses that do this for the first time discover two uncomfortable things. Competitors they’d never considered are winning the AI answer, and at least one AI platform is describing their business inaccurately. Both are fixable, but only once you know.
What GEO looks like across Australian industries
B2B and manufacturing. Buyers now ask AI to build supplier shortlists before your sales team ever hears from them. Detailed capability pages, specification data, Australian compliance information and named case studies with real numbers are what get you onto that shortlist.
Not-for-profit and disability services. Funding bodies, participants and families increasingly research providers through AI. Accessibility is a double win here. The same clear structure and semantic markup that makes a site WCAG-compliant also makes it exceptionally machine-readable. Accessible sites are, almost by definition, GEO-ready sites.
Professional services and finance. These are high-trust categories where AI engines apply stricter sourcing standards. Named authors with credentials, cited claims and a strong third-party reputation footprint aren’t optional. They are the entry fee.
Ecommerce. AI shopping recommendations are exploding, and they are built from product-level depth: complete specifications, honest comparison content, review volume and consistent product data across your site and marketplaces.
Five GEO mistakes we keep seeing
- Treating GEO as a replacement for SEO. AI retrieval leans on search indexes, so weak SEO means you never enter the candidate pool.
- Publishing more generic AI-written content. Engines are drowning in it and cite the original, experience-backed source instead. Volume without substance now actively works against you.
- Blocking AI crawlers, usually accidentally, through Cloudflare defaults or an old robots.txt rule.
- Optimising only your own website while ignoring reviews, PR and community presence, which is half the trust equation.
- Not measuring anything, then declaring GEO “unproven.” You can’t manage a channel you refuse to see.

Frequently asked questions
Everything Australian businesses ask us about getting cited by ChatGPT, Gemini, Perplexity and Google AI Overviews.
What does GEO stand for in marketing?
GEO stands for Generative Engine Optimisation. It is the practice of optimising your content, brand entity and technical setup so generative AI platforms like ChatGPT, Google AI Overviews, Gemini and Perplexity cite and recommend your business in their answers.
Is GEO different from SEO?
Yes, in goal rather than foundation. SEO earns rankings and clicks in traditional search results, while GEO earns citations and recommendations inside AI-generated answers. GEO builds on SEO, since strong technical health and authority remain prerequisites, but it adds entity optimisation, citable content structure and third-party trust signals.
Does my Australian business really need GEO in 2026?
If your customers research before buying, yes. 58% of Australians now use AI tools in an average month, 12% already treat AI as their primary way to find information online, and AI Overviews appear on nearly half of Google queries. Businesses absent from AI answers are invisible during a growing share of the buying journey.
How long does GEO take to show results?
Often faster than traditional SEO. AI engines re-retrieve live web content constantly, so structural improvements, new statistics and crawler fixes can influence answers within weeks. Authority-driven gains such as reviews, PR and entity strength compound over three to six months.
Can anyone guarantee my business will appear in ChatGPT?
No, and you should be sceptical of anyone who promises it. AI outputs vary by user, session and model version. What a credible GEO program does is systematically increase your probability of citation through crawlability, citable content, entity clarity and third-party authority, then measure the improvement.
How do I measure GEO performance?
Track three metrics. Mention rate is how often you appear across a fixed set of 20 or more customer prompts, tested monthly. AI referral traffic is sessions in GA4 from ChatGPT, Perplexity, Gemini and Copilot domains. Answer accuracy and sentiment is how AI describes your business. Our analytics and reporting covers all three.
Does GEO replace my SEO investment?
No, it extends it. Even with Gartner projecting a 25% fall in traditional search volume by the end of 2026, the majority of discovery still happens in traditional search. The winning strategy is layered: SEO for rankings, AEO for answer features, GEO for AI citations. Much of the work serves all three at once.
What is llms.txt and do I need it?
llms.txt is an emerging plain-text standard, placed at yoursite.com/llms.txt, that gives language models a curated summary of your site and its most important pages. It isn’t universally adopted yet, but it costs almost nothing to implement and signals AI-readiness.
