GEO vs SEO vs AEO: What’s the Difference?

Search is changing.
For years, businesses have focused on getting found in Google. That has usually meant investing in SEO, improving website content, working on technical performance, building authority and making sure the business appears when people search for its products or services.
This still matters but people are no longer only searching by typing a few words into Google and scrolling through a list of links. They are asking ChatGPT, Gemini, Perplexity, Microsoft Copilot and Google’s AI-powered search features for direct answers, summaries, comparisons and recommendations.
They are asking things like:
“Who can help a small business in New Zealand improve its SEO?”
“What is the difference between SEO and AI optimisation?”
“How do I optimise my website for ChatGPT?”
“Why is my business not showing up in AI answers?”
That changes the job your website has to do as it does not just need to rank, it needs to be clear enough for search engines and AI systems to understand, trust and use.
That is where SEO, AEO and GEO come in, they are connected, but they are not the same thing.
What you’ll learn in this article
In this article, we’ll cover:
what SEO, AEO and GEO mean
how they are different
how they work together
why SEO is still the foundation
why AI search is changing search optimisation
what NZ businesses should focus on next
What is SEO?
SEO stands for Search Engine Optimisation.
It is the process of improving your website so search engines can crawl it, understand it, index it and show it in search results.
SEO includes things like:
keyword research
page titles and meta descriptions
website structure
internal linking
technical performance
content quality
backlinks
local SEO
Google Business Profile optimisation
user experience
measurement and reporting
For many NZ businesses, SEO is still one of the most important foundations of online visibility. If your website cannot be crawled properly, if your pages are unclear, or if Google cannot confidently understand what your business does, you are already making visibility harder.
SEO helps your business become findable, but being findable is no longer the whole job.
What is AEO?
AEO stands for Answer Engine Optimisation.
AEO is about shaping your content so it can answer specific questions clearly, this became important before AI chat tools became mainstream. Google featured snippets, People Also Ask results, voice search and FAQ-style search results all pushed businesses to create clearer, more direct answers.
AEO focuses on questions like:
What does this business do?
Who does it help?
Where does it operate?
What services does it offer?
What problem does it solve?
What makes it credible?
Good AEO content is usually clear, direct and easy to extract, it often includes FAQs, definitions, short explanations, service summaries, schema markup and well-structured headings. AEO helps your business become answerable, and it is not about writing more content for the sake of it, it is about making sure the important answers are clear, visible and easy to reuse.
What is GEO?
GEO stands for Generative Engine Optimisation.
GEO is about improving how your business is discovered, interpreted, trusted and used by generative AI systems. These systems do not just list search results, they generate answers. They summarise information, compare options, pull from multiple sources and decide which businesses, brands, products, experts or services are relevant enough to mention.
This includes platforms and features such as:
ChatGPT
Google AI Overviews
Gemini
Perplexity
Microsoft Copilot
AI-powered search and answer engines
GEO is not only about whether your page ranks, it is about whether an AI system can understand your business well enough to include it in a generated answer. That means your website and wider online presence need to send clear, consistent signals about who you are, what you do, who you help, where you operate and why you should be trusted.
GEO helps your business become usable by AI systems, as AI can’t recommend what it doesn’t understand.
The simple difference between SEO, AEO and GEO
SEO helps your business show up in search results, AEO helps your business answer specific questions and GEO helps AI systems understand, summarise, mention and recommend your business in generated answers.
They are not competing strategies they build on each other.
SEO gives your website a strong foundation, AEO makes your information clearer and easier to answer from and GEO helps AI systems connect the dots between your business, your services, your location, your expertise and your authority.
Strategy | What it optimises for | Main goal | Typical tactics | Best measurement |
SEO | Traditional search engines like Google and Bing | Rank pages and earn organic traffic | Technical SEO, keywords, internal links, backlinks, page speed and content quality | Rankings, impressions, clicks and organic traffic |
AEO | Answer engines, featured snippets, voice search and answer-style results | Become the direct answer to a specific question | Clear answer paragraphs, FAQs, schema markup, concise definitions and structured content | Featured snippets, answer inclusion, voice visibility and AI answer mentions |
GEO | Generative AI systems such as ChatGPT, Perplexity, Gemini and Google AI Overviews | Be cited, referenced or recommended in generated responses | Entity clarity, structured understanding, authoritative sources, brand consistency and third-party validation | AI citations, brand mentions and recommendation visibility |
AI search optimisation | The full AI-powered discovery landscape | Help AI systems understand, trust and recommend your business | SEO foundations, AEO formatting, GEO signals, entity building and AI visibility testing | Visibility across search, AI answers, citations and enquiries |
SEO is still the foundation of AI visibility
There is a lot of noise around AI search at the moment. Some of it makes it sound like SEO is dead or that businesses should forget about search engine optimisation and focus only on AI. That is not how I see it.
SEO is still the foundation, if your website cannot be crawled, indexed, understood or trusted by Google, it is unlikely to perform well in AI search either. The difference is that SEO now needs to do more than support rankings.
It also needs to help search engines and AI systems understand:
what your business does
who your business helps
where your business operates
what services you offer
what topics you should be associated with
why your business is credible
when your business should be recommended
This is where search engine optimisation in NZ is starting to shift, it is no longer just about keywords, rankings and traffic. Those things still matter, but they need to sit inside a clearer strategy for business understanding.
GEO does not replace SEO services
GEO does not replace SEO services, it builds on them. A strong SEO strategy improves the technical, content and authority signals that search engines need, GEO extends that work by making your business clearer and more usable in AI-generated answers.
For example, SEO might help a page rank for:
SEO consultant NZ
search engine optimisation NZ
small business SEO
SEO services
website optimisation
GEO asks a slightly different question, “can an AI system understand that this business provides SEO consultation, AI search visibility support and strategic search optimisation for small businesses in New Zealand?”
That is a different level of clarity, you are not only trying to match a keyword, you are trying to build a clear, consistent picture of the business.
Why SEO alone is no longer enough
SEO is still necessary, but SEO alone does not always solve the full visibility problem, a website can:
Rank for a keyword and still be poorly understood.
A service page can mention a service but still not explain who it is for, what it includes or why the business is credible.
A business can show up in Google but still be missing from AI-generated recommendations.
This often happens because AI systems are not only looking at isolated keywords, they are trying to understand relationships.
For example, they may need to connect:
the business to its services
the business to its location
the business to its area of expertise
the business to customer problems
the business to reviews, proof and trust signals
This is where deeper ideas like entity clarity and structured understanding matter. I talk about those separately here What is an Entity? and What is Structured Understanding?, but the short version is this: the clearer and more consistent your business is online, the easier it is for AI systems to understand when you are relevant.
Why GEO matters now
People are using AI tools to make decisions, they are asking direct, specific and often conversational questions with an average of 8 - 14 words.
For example: “Who is the best SEO consultant in New Zealand for a small business?” or “What is AI optimisation and do I need it?” vs “AI optimisation” or “SEO”.
In traditional search, someone might see a list of websites and choose where to click but in AI search, the system will summarise the answer first. It may mention some businesses and leave others out, it may cite sources, it may compare options before the person has even visited a website.
That changes the visibility problem, your business may still have a website and it may still rank for some search terms but if AI systems do not clearly understand what you do, where you fit, who you help or why you should be trusted, you may not be included in the generated answer.
How to prepare your business for GEO
You do not need to throw away your SEO strategy and start again, but you do need to look at whether your current search optimisation work is helping both people and AI systems understand your business clearly.
Here are a few practical places to start.
1. Clarify what your business should be known for
Can your website clearly answer:
What do you do?
Who do you help?
Where do you operate?
What problems do you solve?
What services do you offer?
What makes you credible?
If those answers are unclear, GEO becomes difficult.
2. Strengthen your key service pages
Each important service should have enough context to stand on its own.
A good service page should explain who the service is for, what it includes, what problem it solves, when someone might need it and what the next step is. This is especially important for SEO services, AI optimisation, search optimisation and website optimisation pages.
3. Add useful FAQs
FAQs help both people and answer engines, they make it easier to answer specific questions directly. Good FAQs should reflect real customer questions, not just keyword variations.
For example:
What is the difference between SEO and GEO?
Is SEO still important for AI search?
How do I optimise my website for ChatGPT?
What is AEO?
Do NZ businesses need AI optimisation?
4. Keep your business information consistent
Your website, Google Business Profile, social profiles, directories and external mentions should all reinforce the same core business identity.
If one source says you are an SEO consultant, another says digital marketing, another says AI optimisation and another says website support, that can create confusion unless the relationship between those services is clearly explained. Consistency helps AI systems understand the business more confidently.
5. Test how AI systems describe your business
One of the simplest things you can do is test how AI tools currently understand your business.
Try asking ChatGPT, Gemini, Perplexity and Google AI search features questions like:
What does this business do?
Who is this business best suited for?
What services does this business offer?
Is this business a good option for this specific need?
Which businesses offer this service in this location?
Look for missing services, wrong descriptions, weak explanations, outdated information, competitors being mentioned instead or unclear category associations. Those gaps show you what needs to be clarified or reinforced.
How this applies to businesses
For businesses, search optimisation can still be treated as a Google ranking exercise.
A business now needs to think about how it appears across:
Google Search
Google Business Profile
Google AI Overviews
ChatGPT
Gemini
Perplexity
Bing/Copilot
directories
social platforms
review sites
industry sources
This does not mean chasing every platform, it means making sure the core information about your business is clear and consistent wherever AI systems may find it. The businesses that will benefit most are not necessarily the ones producing the most content, they are the ones that are easiest to understand.
GEO, SEO and AEO are not competitors
It is easy to get caught up in the terminology but the point is not to choose between SEO, AEO and GEO. The strongest strategy uses all three, SEO helps search engines find, crawl, index and rank your content, AEO helps your content answer specific questions clearly and GEO helps AI systems understand, trust and use your business information in generated answers.
Together, they support modern search visibility.
Final thought
Search is no longer just about rankings, it is about understanding.
SEO helps your business get found.
AEO helps your business answer questions.
GEO helps AI systems understand and use your business in generated answers.
That is why modern search optimisation needs to bring all three together.
Because AI can’t recommend what it doesn’t understand.
If you want to understand how visible your business is becoming in AI-generated answers, AI Optimisation can help identify where your business is clear, where it is inconsistent and what needs to be strengthened next.
What is the difference between SEO, AEO and GEO?
SEO helps your business appear in search results. AEO helps your content answer specific questions. GEO helps generative AI systems understand, summarise, mention and recommend your business in AI-generated answers.
Is SEO still important for AI search?
Yes. SEO is still important because AI search systems often rely on many of the same signals that traditional search engines use, including crawlability, content quality, authority, structure and trust. The difference is that SEO now needs to support understanding, not just rankings.
What is GEO?
GEO, or Generative Engine Optimisation, is the process of improving how your business appears in AI-generated answers. It focuses on making your business easier for AI systems to understand, verify and include when people ask relevant questions.
What is AEO?
AEO stands for Answer Engine Optimisation. It focuses on creating clear, structured answers to common customer questions so your content can be used in featured snippets, answer boxes and AI-powered search experiences.
How do I optimise my website for ChatGPT?
To optimise your website for ChatGPT and other AI systems, make your business information clear, specific, structured and consistent. Explain what you do, who you help, where you operate, what services you offer and why you are credible. Add FAQs, strengthen service pages and make sure your information is consistent across trusted sources.
