SEO, AEO and GEO: how Australians will find you in the age of AI search

For twenty years, “getting found online” meant one thing: ranking on Google. That’s no longer the whole game. More and more Australians ask AI tools like ChatGPT, Perplexity and Google’s AI Overviews for recommendations, and never scroll a list of blue links at all.

If your business isn’t set up for both worlds, you’re invisible to a growing slice of buyers. Here’s the plain version.

What is SEO?

SEO (Search Engine Optimisation) is the classic discipline: getting your website to rank in Google’s results. It still matters enormously, because most buying journeys still pass through Google. It covers technical health, fast pages, the right keywords, and content that answers what people search for.

What is AEO?

AEO (Answer Engine Optimisation) is about becoming the answer, not just a result. When someone asks a direct question, AI and search engines increasingly lift a single, concise answer to the top. AEO structures your content, with clear questions and direct answers, so yours is the one that gets quoted.

A quick test: if a customer asked your most common question out loud, does a page on your site answer it in two clear sentences near the top? If not, that’s an AEO gap.

What is GEO?

GEO (Generative Engine Optimisation) is the newest layer: shaping what generative AI tools say about your business. You can’t control AI output, but you can strongly influence it. AI engines decide who to mention based on signals of trust: consistent business information across the web, clear authority on a topic, and content they can confidently cite.

GEO is how you become the business ChatGPT or Perplexity names when someone asks “who’s the best option near me?”

Why does this matter for Australian businesses now?

Buyer behaviour is shifting faster than most businesses are reacting. The companies investing in AEO and GEO today are building a head start that compounds. By the time competitors notice, the AI engines already trust and cite the early movers.

What should I do about it?

You don’t need to pick one. They work together: SEO gets you ranking, AEO makes you the answer, and GEO gets AI tools to recommend you by name.

Start by making sure your business information is consistent everywhere online, and that your key pages answer real customer questions clearly and directly. That foundation serves all three.
