GEO vs SEO vs AEO: What NZ Businesses Need to Know

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, making sure the business appears when people search for its products or services.

This still matters but people are no longer only typing a few words into Google and scrolling through a list of links. They're asking ChatGPT, Gemini, Perplexity, Microsoft Copilot and Google's AI-powered search features for direct answers, summaries, comparisons and recommendations, questions like "who can help a small business in New Zealand improve its SEO," or "why is my business not showing up in AI answers."

That changes the job your website has to do, it doesn't just need to rank, it needs to be clear enough for search engines and AI systems to understand, trust and use.

That's where SEO, AEO and GEO come in. They're related, they're also not as cleanly separated as most explanations make them sound and being upfront about where the line actually blurs matters more than pretending it doesn't.

What Is SEO?

SEO: Search Engine Optimisation is the process of improving your website so search engines can crawl it, understand it, index it and show it in search results. It includes keyword research, page titles and meta descriptions, site structure, internal linking, technical performance, content quality, backlinks, local SEO, Google Business Profile optimisation and user experience.

For most NZ businesses, SEO is still the foundation of online visibility. If your website can't be crawled properly, if your pages are unclear, or if Google can't confidently understand what your business does, you're already making visibility harder for yourself. SEO helps your business become findable but being findable is no longer the whole job.

What Is AEO?

AEO: Answer Engine Optimisation is about shaping content to answer specific questions clearly. The term predates mainstream AI chat tools; it originally described optimising for Google featured snippets, People Also Ask results, voice search and FAQ-style results.

Good AEO content is direct and easy to extract, FAQs, definitions, short explanations, service summaries, schema markup, clear headings. It's not about writing more content for the sake of it, it's about making sure the important answers are clear, visible and easy to reuse.

What Is GEO?

GEO: Generative Engine Optimisation is about improving how your business is discovered, interpreted, trusted and used by generative AI systems: ChatGPT, Google AI Overviews, Gemini, Perplexity, Microsoft Copilot. These systems don't just list results, they generate answers, summarising information, comparing options, and deciding which businesses are relevant enough to mention.

GEO isn't only about whether your page ranks it's about whether an AI system understands your business well enough to include it in a generated answer. AI can't recommend what it doesn't understand.

Where AEO and GEO Actually Overlap

Here's the honest version most explanations skip: the line between AEO and GEO isn't as clean in practice as it is in theory.

AEO was coined to describe optimising for answer-style results before generative AI chat interfaces existed. But almost everything that used to count as "AEO" like featured snippets, voice search, People Also Ask, has since been absorbed into generative, AI-written answers. Google's own featured snippets now sit alongside AI Overviews built on the same generative technology GEO is written to address. The industry hasn't settled on one term, and you'll see AEO, GEO, and "AI search optimisation" used interchangeably depending on who's writing.

That's not a reason to ignore the distinction entirely. It's a reason to treat AEO as describing a format - direct, structured, answer-ready content and GEO as describing the target - the generative systems now serving most of those answers. In practice, doing GEO well requires AEO's formatting discipline. They're not competing strategies, they're increasingly the same work, viewed from two different angles.

How SEO, AEO and GEO Work Together

SEO helps your business show up in search results, AEO makes your information clear enough to answer specific questions directly and GEO helps AI systems understand, summarise and recommend your business inside generated answers. None of the three replaces the others. SEO gives your website a foundation, AEO makes that foundation answer-ready, and GEO extends it into systems that generate rather than list.

Strategy	What it optimises for	Main goal	Typical tactics
SEO	Traditional search engines like Google and Bing	Rank pages and earn organic traffic	Technical SEO, keywords, internal links, backlinks, page speed, content quality
AEO	Answer engines, featured snippets, voice search	Become the direct answer to a specific question	Clear answer paragraphs, FAQs, schema markup, concise definitions
GEO	Generative AI systems: ChatGPT, Perplexity, Gemini, AI Overviews	Be cited, referenced or recommended in generated responses	Entity clarity, structured content, authoritative sources, brand consistency

The AI Visibility Engine™: How We Actually Approach This

SEO, AEO and GEO are useful shorthand for what the industry as a whole is doing. They're not our methodology, the AI Visibility Engine™ is.

Rather than treating "AI search optimisation" as a vague fourth bucket sitting next to the other three, we work through five specific, non-linear stages.

Entity Definition: is this business a distinct, understandable thing to AI systems? Structured Understanding: is the information machine-readable and consistent? Authority Signals: is there enough credible, external proof for AI to trust the business? Answer Alignment: is the business connected to the actual questions AI systems are already answering?

Recommendation Reinforcement: does that trust translate into AI actively choosing to name the business, repeatedly?

Worth being precise about one thing here, since the terms sound alike: Answer Alignment, as a stage in our framework, means finding and closing the specific gaps where AI systems are already forming answers about your industry without you in them. That's a narrower, more deliberate exercise than the general industry term AEO, which, as covered above mostly describes content formatting. You can do AEO formatting well and still not be answer-aligned, if nobody's checked whether AI is already answering a question you have nothing published on.

SEO Is Still the Foundation

There's a lot of noise suggesting SEO is dead, or that businesses should abandon it and focus only on AI. that's not accurate. If your website can't be crawled, indexed, understood or trusted by Google, it's unlikely to perform well in AI search either. What's changed is that SEO now needs to do more than support rankings, it needs to help both search engines and AI systems understand what your business does, who it helps, where it operates, and why it's credible.

Why SEO Alone Isn't Enough Anymore

A website can rank for a keyword and still be poorly understood. A service page can mention a service without explaining who it's for or why the business is credible. A business can show up in Google and still be missing from AI-generated recommendations entirely.

This happens because AI systems aren't just reading isolated keywords, they're trying to understand relationships: the business to its services, its location, its area of expertise, its proof points. This is exactly what Entity Definition and Structured Understanding are built to solve. More on Entity Definition here, more on Structured Understanding here.

How to Prepare Your Business for GEO

You don't need to abandon your SEO strategy, you need to check whether your current work is helping both people and AI systems understand your business clearly.

Clarify what your business should be known for. Can your website plainly answer what you do, who you help, where you operate, and what makes you credible? If those answers are unclear, everything downstream gets harder.

Strengthen your key service pages. Each important service should explain who it's for, what it includes, what problem it solves, and when someone needs it, not just describe the service in general terms.

Add FAQs when appropriate that reflect real questions. Pull them from actual customer enquiries, not keyword guesses.

Keep your business information consistent across your website, Google Business Profile, social profiles, directories and any external mentions. If one source calls you an SEO consultant and another calls you a digital marketing agency, that fragments the signal AI systems are trying to piece together.

Test how AI systems currently describe your business. Ask ChatGPT, Gemini and Perplexity what your business does, who it's best suited for, and which businesses they'd recommend for the same need. The gaps you find show exactly what needs strengthening first.

Frequently Asked Questions

What's the actual difference between SEO, AEO and GEO? SEO gets your business found in search results. AEO formats your content to answer specific questions directly. GEO is about being understood, trusted and recommended by generative AI systems specifically. In practice, AEO and GEO overlap heavily, most current answer engines are generative, so good AEO formatting is now part of doing GEO well.

Is SEO still important for AI search? Yes. AI search systems rely on many of the same underlying signals traditional search does - crawlability, content quality, authority, structure, trust. SEO now needs to support understanding, not just rankings.

How do I optimise my website for ChatGPT specifically? Make your business information clear, specific and consistent everywhere it appears - your site, directories, and any independent sources that mention you. ChatGPT has no way to verify a claim it's only seen once, from you, so consistency across sources matters more here than almost anywhere else.

Do I need to pick one of SEO, AEO or GEO? No. They're not competing strategies. Most businesses need all three working together, which is what the AI Visibility Engine™ is actually built to do.

Final Thought

Search is no longer just about rankings, it's about understanding. SEO helps your business get found, AEO helps it answer questions clearly and GEO helps AI systems understand and use that information in generated answers and none of that happens by accident, which is why it needs a structured approach rather than three separate, disconnected efforts.

AI can't recommend what it doesn't understand.
