GEO, SEO and AEO: What’s the Difference, and Where Should an Australian Business Spend?
Plenty of Australian business owners cannot separate GEO, SEO and AEO, which means they cannot say where the money ought to go either. The three are not competing products. They are three stages in how people look for things, and once the line of travel is clear, so is the way to combine them.
The three, in one line each
- SEO (search engine optimisation). Getting you placed high in Google’s results.
- AEO (answer engine optimisation). Getting you into the featured answer, the voice result and the question box.
- GEO (generative engine optimisation). Getting you quoted and recommended directly by ChatGPT, Gemini and AI Overviews.
Each describes where the customer ends up looking, not a different kind of work. The pages underneath are largely the same pages.
Do they replace one another?
They do not. GEO does not retire SEO; it sits on top of it. A site that performs well with generative engines almost always has sound fundamentals underneath, for the simple reason that what an AI chooses to quote is usually a page that is clearly structured, credible, and already recognised by search engines. The machine is not looking for a new kind of website. It is looking for a trustworthy one that happens to state its answers plainly.
For an Australian local business, the sensible posture is all three at once: SEO as the floor, AEO to win the answer, GEO to be the citation.
The order to buy them in
Budgets are finite, so sequence matters more than ambition.
| Stage | What to do first |
|---|---|
| Just starting | SEO fundamentals: the site itself, local keywords, Google Business Profile and genuine reviews |
| Traffic arriving | AEO: FAQs, structured question-and-answer content, the answer stated first |
| Holding position | GEO: a verifiable entity, quotable facts, content an AI is willing to adopt |
The economy of it is that the layers share their raw material. One question answered properly — in writing, with the local detail intact and the structure marked up — earns its keep in a search result, an answer box and an AI’s recommendation at once. Which is why doing all three is less than three times the work, and doing only the first leaves customers on the table.
Frequently asked questions
What is the difference between GEO, SEO and AEO in one line each?
SEO gets you ranked in Google’s results. AEO gets you into the featured answer, voice results and question boxes. GEO gets you quoted and recommended by ChatGPT, Gemini and AI Overviews. Same underlying content work, three different places the customer ends up looking.
Does GEO replace SEO?
No, it stacks on top of it. A site that does well at GEO usually has sound SEO and AEO underneath, because what an AI quotes tends to be pages that are clearly structured, credible and already recognised by search engines. For an Australian local business the correct posture is all three at once: SEO as the floor, AEO for the answer box, GEO for the citation.
Is SEO alone still enough?
For now, more or less. Over time, no. Customers are moving quickly towards asking an AI, and a business doing only SEO simply misses that entrance — the traffic that arrives because a machine recommended you by name.
On a limited budget, which comes first?
Get SEO and your Google reviews solid first, then add AEO and GEO on top. The good news is that the content work overlaps heavily: one properly written answer serves a search result, a featured answer and an AI citation at the same time, so the second and third layers cost far less than the first.
What is AEO, exactly?
Work that gets ChatGPT, Perplexity and Google’s AI answers to cite you directly. It runs on question-and-answer content, structured data and trust signals (E-E-A-T).
What is structured data?
A machine-readable way of stating who you are, what you do, where you are and how you are regarded — so Google’s rich results and AI tools describe you accurately instead of guessing.
Why can’t customers find me?
Usually missing local terms, thin content, or technical problems underneath. Fix those three and the site comes back into view.
How long before the work shows results?
The technical and structural changes are crawled as soon as they are live. SEO and AI citations generally start within weeks, and evergreen content compounds month on month.
How do I judge whether it worked?
By search visibility, AI citations and enquiries that actually arrive — not by performance scores. A tidy report that brings nobody through the door has measured nothing.
Roughly what does this cost?
It depends on whether content, SEO and AEO are inside the quote. Melmel does design and build with AEO and AI SEO from $1,000 a month, with no lock-in contract, and the $199 whole-site AI audit comes off your first month.
