What is Generative Engine
Optimisation?

The short answer

Generative Engine Optimisation (GEO) is the practice of structuring your content so that AI-powered tools - ChatGPT, Perplexity, Google AI Overviews, Microsoft Copilot - cite, quote, or recommend your website when they generate answers for users.

Think of it like this: traditional SEO gets you a blue link in a list of 10 results. GEO gets you mentioned in the answer itself - before the user even looks at a list. That's a fundamentally different kind of visibility, and it's becoming more valuable every quarter.

Why GEO matters for Australian businesses right now

A few years ago, AI search was a curiosity. Now it's a mainstream channel. Independent tracking of Australian search results puts Google AI Overviews at roughly 38-40% of queries, well above the global average. ChatGPT has over 900 million weekly active users globally (per OpenAI, February 2026), many of whom use it to research products, services, and local providers. Perplexity explicitly shows its sources - meaning citations drive real referral traffic.

For Australian businesses, this creates both a problem and an opportunity:

• The problem: if your competitors are being cited and you're not, you're invisible in a growing share of the market's research process.
• The opportunity: most Australian businesses haven't started optimising for AI search yet. First movers gain a positioning advantage that compounds over time.

How AI tools decide what to cite

AI large language models don't rank pages like Google does. They don't have a PageRank equivalent. Instead, they draw on a combination of training data and (in tools like Perplexity and AI Overviews) real-time web retrieval. Several signals influence whether your content becomes a source:

Factual density

AI tools strongly prefer content that makes specific, verifiable claims. Vague language gets passed over. "Our service delivers results" gets ignored. "Our clients see an average 38% improvement in organic traffic within 90 days" gets cited (a claim like that only belongs on your site if the number is real and measured - never invent it). Specificity is the currency of GEO.

Structural clarity

Content that uses headings, definitions, bullet lists, and clean logical flow is easier for AI systems to parse and extract. If a passage is quotable as-is - a clean definition, a specific statistic, a numbered process - it's far more likely to appear in an AI-generated answer.

Source credibility signals

AI systems learn from the web's existing authority signals. Content that cites academic research, industry reports, or government data gets treated as more credible. Original research you've conducted yourself is especially powerful - it becomes a unique source that can't be replicated elsewhere.

Entity recognition

AI models understand "entities" - named companies, people, products, locations. The more your brand appears alongside relevant entities in credible contexts (news articles, industry directories, review platforms), the stronger your signal. This is why consistent brand presence across the web matters for GEO, not just traditional SEO.

How GEO differs from SEO

They share a foundation - both reward genuinely useful content - but they diverge in important ways:

• SEO optimises for ranking signals: links, keyword placement, page speed, technical health.
• GEO optimises for citation signals: authority, factual density, structured language, entity strength.

The good news: a well-executed SEO strategy provides a strong base for GEO. High-authority sites with well-structured content are more likely to be cited. But GEO requires deliberate additional effort - you can't just do SEO and assume GEO takes care of itself.

5 things you can do this week

You don't need to rebuild your entire site. Start with these:

1. Add a crisp definition to every key concept page. AI tools love clean, one-paragraph definitions they can quote directly.
2. Replace vague claims with specific numbers. "improves rankings" -> "improved rankings by 34% within 60 days."
3. Cite your sources. Link out to the research, reports, and data you reference. It signals credibility to AI retrieval systems.
4. Add FAQ sections with conversational questions. AI Overviews frequently pull from FAQ-structured content to answer "how" and "what" queries.
5. Add schema markup. FAQPage, Article, and HowTo schema make it easier for AI systems to understand what type of content each section contains.
