The Short Answer: Do Them in This Order
Build the technical foundation first, then SEO, then AEO structure, then GEO entity work. They're sequential because each one depends on the last. A site AI crawlers can't reach won't be cited no matter how good its schema is, and entity signals mean nothing if the pages they point at are thin.
Most Australian businesses reading about SEO, AEO and GEO assume the answer is a three-way budget split. For the majority it isn't. It's a sequence, and you're probably at step one.
If you want the definitions, they live elsewhere: what generative engine optimisation is and our guide to answer engine optimisation. This article assumes you already know roughly what the three acronyms mean and want to know what to actually do.
What Each One Owns
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank in Google's organic results | Be extracted as the direct answer | Be named inside an AI-generated recommendation |
| Main lever | Content quality and backlinks | Content structure and schema | Entity consistency and third-party citations |
| Measured by | Rankings, sessions, conversions | Featured snippets, PAA appearances, AI Overview pulls | Citation frequency across ChatGPT, Gemini, Perplexity |
| Reporting tool | Search Console, rank tracker | Search Console, manual SERP checks | Manual prompt audit. Nothing automated exists yet. |
| Time to move | 3–6 months on low-competition terms | 4–12 weeks once the content exists | 4–8 weeks on Perplexity and Google AI Mode, 3–6 months on ChatGPT |
| Who it's for | Everyone | Anyone already publishing content | Businesses with an existing online footprint to build on |
Read the bottom row twice. GEO is the only one of the three with a prerequisite.
What to Do First, by Situation
You have a new or thin website
Do SEO. All of it. Ignore the other two for now.
This will feel like the wrong advice in 2026, because every agency pitch you receive will be about AI search. But AEO structure on a five-page site gives an AI system better-formatted content it still has no reason to trust, and GEO entity work with nothing behind it just points at an empty room.
Get the technical foundation clean, publish content that answers real buyer questions, claim and complete your Google Business Profile, and build the first twenty reviews. That work feeds all three disciplines. Come back in six months.
You rank well on Google but never appear in AI answers
This is the situation GEO was built for, and it's more common than people expect. Good rankings, decent traffic, and total absence from ChatGPT.
Start with crawler access, because it's binary and it's fast. Confirm GPTBot and the other AI crawlers are allowed in robots.txt, then submit your sitemap to Bing Webmaster Tools, which is what ChatGPT and Copilot read. Then restructure your highest-value pages for extraction: a short direct answer under each heading, FAQ sections with FAQPage schema. Then work on entity signals, which is the slow part.
Budget guide for this situation: keep SEO spend where it is, and add roughly 20–30% on top for the AEO and GEO work rather than reallocating. Cutting SEO to fund GEO is the most common expensive mistake we see. Google's blue links still drive most commercial search traffic in Australia, and the technical work underneath SEO is what makes GEO possible in the first place.
You rank nowhere and appear nowhere
Then your problem isn't which acronym to pick. Your problem is that not enough of the internet knows you exist.
The honest sequence here: fix the Google Business Profile, get reviews, get listed in the Australian directories that actually rank (Clutch, Yellow Pages, True Local, industry bodies), publish four pieces of content worth citing. None of that is SEO, AEO or GEO strictly speaking. All of it is the prerequisite.
You're in a category where AI adoption is running ahead of you
Professional services, health, anything sold to under-45s. Telsyte's Australian Artificial Intelligence Study 2026 found 12% of Australians now name AI tools as their primary way of finding information online, up from 5% a year earlier, and that number skews young. If your buyers are in that cohort, move GEO earlier in the sequence than the guidance above suggests.
How to Split the Budget
There's no universal answer, but there is a sensible default for an Australian SME already investing in search.
70% SEO, 20% AEO, 10% GEO — for a business with an established site and rankings to protect. The SEO portion keeps the channel that currently pays for itself. The AEO portion is mostly content restructuring, which is cheap because it's editing rather than creating. The GEO portion buys the slow entity work: directory listings, digital PR, review generation.
Two adjustments worth making.
If you're getting good organic traffic but conversions have flattened while impressions hold steady, shift to 50/25/25. That pattern often means answers are being taken from your content without the click.
If you're in a category with almost no AI citation competition — most local Australian trades and services still qualify — the GEO slice punches above its weight. Going to 60/20/20 can be justified, because being one of three named businesses in an AI answer is worth more than being seventh on Google.
Can One Agency Do All Three?
Technically yes. Most that claim to, can't.
The test isn't whether they say the words. It's whether they can describe their measurement method for the third one. SEO measurement is standard and everyone has it. AEO measurement is mostly Search Console plus manual checking, also fine. GEO measurement has no tool, which means there's nothing to hide behind.
Ask any agency: how will you show me whether my AI visibility improved? If the answer is a dashboard with an "AI score", ask what feeds it. If the answer is a manual prompt audit run monthly with the results recorded, they've actually done this before.
For what it's worth, that's the method we use: 15 to 20 buyer prompts run across ChatGPT, Gemini and Perplexity, logged with dates, repeated every month. It's laborious. It's also the only honest option currently available, and the trend line after two months is genuinely useful.
What Happens If You Only Do Traditional SEO
Nothing dramatic, for now. That's the part people get wrong in both directions.
You won't fall off a cliff. Google's organic results still handle the bulk of commercial search in Australia, and a business ranking well today will keep getting traffic tomorrow. The doom-marketing around AI search is overdone.
What you will lose is the top of the funnel, slowly. Buyers who used to arrive at your site via a research query now get that answer from an AI assistant instead, and only search directly once they already have three names in mind. If you're not one of the three, you're competing for the click after the decision has narrowed.
That's the cost. It's real and it's gradual, which is exactly why it's easy to ignore for another year.
One more consideration in your favour if you do move: Telsyte found 52% of Australians believe sponsored AI answers are less trustworthy than organic ones, and only 27% are comfortable seeing ads inside AI answers. Organic citation is the route your buyers already prefer, and it's the one you can't buy.
Where to Start This Week
Open your robots.txt and confirm GPTBot, ClaudeBot, PerplexityBot and Google-Extended are allowed. Then run the 15-prompt audit and write down what comes back. Those two things cost nothing and will tell you which of the three disciplines your budget actually belongs in.
If you'd rather not run it yourself, our SEO agency services and AI marketing services include the audit at no cost, and the sequencing recommendation that comes out of it is specific to what we find rather than a template.
Frequently Asked Questions
What is the difference between SEO, AEO and GEO?
SEO targets rankings in Google's organic results. AEO structures content so it can be extracted as a direct answer, in featured snippets and AI summaries. GEO builds the entity signals and citations that make an AI system willing to name your business in a generated recommendation. They share a technical foundation but measure different outcomes.
Should I do SEO or GEO first?
SEO first, in almost every case. GEO depends on having content and credibility for an AI system to draw on, and SEO is what builds both. The exception is a business that already ranks well and has a solid online footprint but never appears in AI answers — that business should move on GEO now.
How should I split my budget between SEO, AEO and GEO?
For an established Australian SME, roughly 70% SEO, 20% AEO and 10% GEO is a sensible default. Shift toward 50/25/25 if impressions are holding but clicks are falling, which suggests answers are being taken from your content. Add to the GEO slice if your category has little AI citation competition.
Do I need all three, or can I pick one?
You can start with one, and for most businesses that one is SEO. Picking GEO alone rarely works because it has a prerequisite: an AI system needs something credible to cite. Picking AEO alone is cheap and worth doing, since it's mostly restructuring content you already have.
Does GEO replace SEO?
No. It extends it. Google's organic results still drive the majority of commercial search traffic in Australia, and the technical work underneath good SEO is what makes a site citable by AI systems in the first place. Cutting SEO spend to fund GEO usually costs more than it gains.
Which one delivers results fastest?
AEO, typically. Restructuring existing content for extraction can show up in featured snippets and AI Overviews within four to twelve weeks. GEO technical fixes move Perplexity and Google AI Mode in roughly four to eight weeks. SEO takes three to six months on lower-competition terms. ChatGPT is the slowest at three to six months.
Can one agency handle all three?
Yes, but verify it. Ask how they will measure AI visibility specifically. A manual prompt audit run monthly and logged over time is the real answer. A dashboard showing an unexplained "AI score" usually is not.
How do I measure each of the three separately?
SEO through Search Console and a rank tracker. AEO through featured snippet and People Also Ask appearances, checked manually. GEO through a recurring prompt audit across ChatGPT, Gemini and Perplexity, recording which businesses get named and which sources get cited. There's no automated tool for the third yet.
Is AEO just a subset of GEO?
They overlap heavily and plenty of people use the terms interchangeably. The practical distinction: AEO is about content structure, GEO adds the entity and citation work that happens largely off your own website. If an agency treats GEO as purely an on-site job, they're describing AEO.
What happens if I only do traditional SEO in 2026?
You keep most of what you have. Google's organic results still carry the bulk of Australian commercial search. What you lose is top-of-funnel discovery, gradually, as research queries move to AI assistants and buyers arrive at search with a shortlist already formed. The effect is slow enough to ignore, which is why most businesses will.
