Generative Engine Optimisation (GEO) is the practice of getting your business named, cited and recommended inside the answers that AI engines like ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews generate. If search engine optimisation was about ranking a link, GEO is about becoming part of the answer itself.

For Australian businesses, this shift is already underway. Buyers are asking AI for recommendations before they ever see a list of blue links. This guide explains what GEO is, how it differs from SEO, and how to actually do it.

GEO vs SEO: what’s the difference?

Traditional SEO aims to rank your page in a list, then earn the click. GEO aims to get your business mentioned inside the AI-written answer, often before any links appear. The two are related — good SEO foundations help GEO — but the mechanics differ:

  • SEO optimises pages for keywords and rankings.
  • GEO optimises your entity — the facts, structure, citations and authority that let an AI confidently describe and recommend you.

SEO still matters. But increasingly, GEO is what determines whether you’re recommended at the exact moment a buyer is deciding.

The four pillars of GEO

1. Entity clarity

AI engines build an understanding of your business from everything they can find. If those sources are consistent and well-structured, the model is confident. If they conflict, it hedges or skips you. Lock down your core facts — name, location, services, pricing, contact — and make them machine-readable with schema markup.

2. Structured, answer-shaped content

Models prefer content that directly answers a question. Write in clear sections with descriptive headings, lead with the answer, and back it with specifics. A well-built FAQ that mirrors the questions your buyers ask is one of the most cite-able assets you can publish.

3. Citations and authority

What others say about you carries far more weight than what you say about yourself. Accurate mentions on trusted directories, industry bodies, reputable publications and genuine reviews give AI engines the corroboration they need. Authority built this way benefits every engine at once.

4. Measurement

GEO without measurement is guesswork. Test the real prompts your buyers use, track who gets recommended, and watch how your share moves over time. This turns GEO from a vague idea into a managed campaign with clear wins and gaps.

How long does GEO take?

An initial audit can be delivered in days, but meaningful movement in AI answers typically takes 60–90 days as engines re-crawl and re-evaluate your authority. GEO is a compounding investment: the entity clarity and citations you build keep paying off as AI adoption grows.

Common GEO mistakes

  • Inconsistent business information across your site and listings, which destroys model confidence.
  • Marketing-speak instead of answers — vague claims that AI can’t quote.
  • No structured data, leaving your facts locked inside design.
  • Hiding pricing and process, denying the model the concrete detail it rewards.
  • No tracking, so you never know if it’s working.

Getting started with GEO

GEO rewards businesses that move early, while categories are still uncrowded in AI answers. At AIRank.au we run a transparent AI Visibility Audit to show exactly where you stand across every major engine, then build the entity clarity, content and citations that get you recommended. You can see our full approach and transparent pricing at any time.

The question is no longer whether AI will shape how customers find you. It’s whether your business will be part of the answer.
