GEO vs SEO vs AEO: what Australian small businesses need in 2026

Last updated: 5 November 2026

Quick answer: GEO vs SEO is mostly a difference in where your business shows up, not a new discipline. SEO helps your pages rank in search results. GEO (generative engine optimisation) and AEO (answer engine optimisation) aim to get your business used in AI written answers. Google says the same SEO foundations apply to its AI features, so most small businesses should strengthen SEO first, then add what AI answers need.

What SEO, GEO and AEO each mean

SEO, GEO and AEO are three names for helping customers find you through search, each focused on a different kind of result. SEO targets ranked links, AEO targets direct answers, and GEO targets answers written by generative AI.

• SEO (search engine optimisation) improves your website so it appears in organic search results on Google and Bing. If you need the basics, start with our guide on what SEO is and why it matters.
• AEO (answer engine optimisation) shapes your content so a search engine or assistant can lift a clear answer from it, such as a featured snippet or a spoken answer.
• GEO (generative engine optimisation) aims to make your content visible inside answers written by AI tools such as Google AI Overviews, AI Mode or ChatGPT. The term comes from a 2023 research paper, Generative Engine Optimization by Aggarwal and colleagues, which describes GEO as a way to improve content visibility in generative engine responses.

GEO is not geo-targeting

In this article, GEO means generative engine optimisation, not geographic targeting. Some agencies and search results use "geo SEO" to mean local or location-based SEO, which is a different topic.

Geo-targeting is about showing ads or pages to people in a set location. Local SEO is about ranking for searches near your business, such as "electrician Epping". Generative engine optimisation is about AI answers. The overlap is real, because AI answers to local questions often draw on local information. That overlap is covered in the local SEO section below.

How Google AI Overviews and AI Mode change what customers see

AI Overviews and AI Mode give searchers a written summary with supporting links, so fewer customers start by scanning a list of ten results. Your page can still earn a visit, but it now competes to be one of the links inside the answer.

Google explains in its guidance on AI features and your website (last updated 10 December 2025) that both features may use a "query fan-out" technique. That means running several related searches across subtopics and sources to build one response. For a small business, a single customer question can pull from pages that answer the smaller questions behind it, such as cost, timing and service area.

A real local example from Google AI Overviews

Taylors Rd Dental is a dental clinic in Kings Park, Melbourne, and a PMGS client. PMGS captured Google AI Overview screenshots showing the clinic mentioned for searches including "children's dentist Taylors Road", "emergency dentist Taylors Road" and "dental implants Taylors Road". They show how a local business can appear in an AI generated search answer alongside organic results and local listings.

AI search results can change depending on the query, location and time. These screenshots document actual appearances rather than guaranteed ongoing placements. This example is about search visibility only and is not dental or clinical advice.

What stays the same: the SEO foundations AI answers rely on

Google says there are no additional requirements to appear in AI Overviews or AI Mode beyond its normal search requirements. A page must be indexed and eligible to show in Google Search with a snippet to be a supporting link.

The same Google guidance says you don't need new machine readable files, AI text files or special schema markup to appear in these features. It recommends the usual foundational practices, including:

• letting Google crawl your pages
• making important content available in text, not only in images or video
• keeping structured data consistent with the visible text on the page
• giving visitors a good page experience
• keeping your Business Profile information up to date

So the work that helps you rank is also the work that makes your pages usable in AI answers. If an agency tells you that GEO replaces SEO, ask how its plan differs from those foundations.

What to add for AI answers: a small business checklist

None of these steps guarantees an AI citation, a ranking or extra traffic. They make your pages clearer and easier to quote.

1. Answer the main question first. Put a two or three sentence answer near the top of each service page and article.
2. Write sentences that stand alone. Name the service, the place and the subject, so a quoted sentence still makes sense out of context.
3. Cover the follow-up questions. Add short sections on cost factors, timing, service areas and what is included, because AI features may search subtopics.
4. Keep facts consistent. Your business name, address, phone, hours and services should match on your website, Google Business Profile and directories.
5. Use structured data honestly. Only mark up what is visible on the page.
6. Show who is behind the business. Add real staff names, credentials and contact details you are happy to publish.
7. Check your pages are indexed. Use Google Search Console to confirm your key pages appear in Google.

What we change and what we leave alone

At PMGS Digital, we focus on improving a website's existing SEO foundation rather than rebuilding everything for AI search. We review service pages, improve content clarity and answer common customer questions. We strengthen internal links and make sure important business information is accurate and consistent. We also check technical SEO, page indexing and relevant structured data to help search engines understand the website.

We leave well performing pages, useful content and established SEO structures alone unless there is a clear reason to improve them. We don't rewrite every page just to include AI related keywords or add unnecessary schema markup. The goal is a website that is more useful for customers and easier for AI search systems to understand and reference.

Where local SEO and your Google Business Profile fit in

For local searches, your Google Business Profile is one of the main sources Google uses, so local SEO matters for AI answers too. Google lists keeping Business Profile information up to date among its recommended practices for AI features.

Google's help page on improving your local ranking says local results are mainly based on relevance, distance and how well known a business is (prominence). Google recommends complete and accurate business details, such as your address, hours and business category. It also notes that reviews and links to your business feed into prominence, and that you can't pay for a better local ranking. Distance depends on where the searcher is, so you can't change it.

Do you need a separate GEO or AEO agency?

Most Australian small businesses do not need a separate GEO or AEO agency, because the core work overlaps with good SEO. A separate budget makes more sense once your SEO foundations are already solid.

For most small businesses, we recommend including GEO and AEO within your existing SEO strategy rather than paying for a completely separate service. Traditional SEO and AI search optimisation share many fundamentals, including helpful content, clear website structure, technical accessibility and trustworthy business information.

You will usually get better value by improving your core service pages, local SEO and Google Business Profile before spending money on a separate GEO package. As AI search becomes a bigger source of customer enquiries, you can invest more in monitoring your visibility and improving how your services are represented across AI platforms.

AI search pitches to be cautious of

Be cautious of agencies promising guaranteed rankings, recommendations or first position placements in ChatGPT, Google AI Overviews or other AI search platforms. No agency can guarantee that an AI system will recommend a particular business.

We would also question expensive GEO packages sold without an explanation of what will actually change on the website or how results will be measured. AI search optimisation should involve genuine improvements to website quality, content and credibility. It should not simply mean adding keywords, generating large amounts of AI written content or installing a special file.

Before you sign up, ask the provider:

• What work is included, and what will you change that my SEO provider does not already do?
• How does this support my existing SEO?
• What measurable business value can I reasonably expect, and how will you measure AI visibility?

Frequently asked questions

What does GEO stand for instead of SEO?

GEO stands for generative engine optimisation. It focuses on making your content visible in answers written by AI tools, while SEO focuses on ranking pages in search results. In some local marketing contexts, "geo" refers to location targeting, which is a different topic.

What is AEO vs SEO?

AEO, or answer engine optimisation, aims to make your content the source of a direct answer, such as a featured snippet or voice result. SEO is broader and covers technical health, content, links and local signals. Good AEO sits inside good SEO.

Is AEO or AI replacing SEO?

No. Google says its AI features rely on the same foundational SEO practices as normal search, and a page must be indexed and eligible for a snippet to appear as a supporting link. AI changes how results look, but SEO is still the base.

Is SEO still relevant in 2026?

Yes. AI Overviews and AI Mode in Google draw on pages that are indexed and eligible to appear in search. Without SEO foundations, your pages are less likely to be found by either traditional results or AI answers.

What is GEO in AI search?

In AI search, GEO is the practice of shaping your content so generative AI tools can understand, use and link to it. In practice, that means clear answers, accurate facts, consistent business details and pages search engines can crawl and index.
