SEO vs AEO vs GEO: what Australian businesses actually need
By AI Digital Marketings · Published · Updated
What is the difference between SEO, AEO and GEO?
SEO optimises for ranking positions in traditional search results. AEO, or answer engine optimisation, targets being extracted as the direct answer in featured snippets and AI Overviews. GEO, or generative engine optimisation, targets being recommended inside AI assistants such as ChatGPT, Perplexity and Gemini. They share technical foundations but differ in what counts as success.
The short version
SEO wins a position. AEO wins the answer. GEO wins the recommendation.
All three depend on the same foundations — a crawlable site, credible authority, and content that genuinely addresses the query. What differs is the surface where success is measured.
Where SEO still dominates
Commercial and transactional searches remain click-driven. Someone comparing prices, checking availability or ready to book still visits websites.
For most Melbourne service businesses, these queries generate the majority of revenue, which is why conventional SEO remains the priority rather than a legacy concern.
Where AEO takes over
Informational queries increasingly resolve on the results page. The user reads the overview or snippet and moves on.
For these, the realistic goal shifts from earning the click to being the cited source — which still builds brand recognition and feeds the consideration stage.
Why GEO is worth starting early
Referral volume from AI assistants is still modest for most Australian businesses, but growing, and almost nobody is deliberately competing for it.
The cost of establishing presence now — consistent factual information across the sources these systems retrieve from — is far lower than it will be once the channel is contested.
How to split a limited budget
For most businesses: roughly 70 percent conventional SEO, 20 percent AEO structuring on existing content, and 10 percent GEO groundwork.
The AEO portion is largely restructuring what you already publish, which makes it the cheapest of the three to add.
Frequently asked questions
01Is GEO just a rebranded version of SEO?
No, though vendors overselling it have muddied the term. GEO depends far more on off-site consensus and the sources models retrieve from than on your own page structure, which makes the tactics genuinely different even where the foundations overlap.
02Should small businesses bother with AEO?
Yes, because it is mostly restructuring rather than new production. Rewriting the opening paragraph of your key pages to answer directly costs very little and improves both snippet eligibility and readability.
03Which matters most in 2026?
SEO still drives the most revenue for most Australian businesses. AEO is the cheapest addition. GEO is the best long-term positional bet. In that order for most budgets.
