If you run a business, you have probably heard a few new acronyms thrown around lately: AEO, GEO, AI search, answer engines, AI Overviews. They sound like a whole new set of skills you are suddenly meant to have mastered. The good news is that most of the confusion comes from the jargon, not the ideas. Strip the labels back and they describe one simple shift in how people find information online.

This guide defines each term in plain English and shows why you should treat them as a single job, not three separate projects.

The shift these terms are describing

For twenty years, search meant typing a few words into Google and getting a list of blue links. You clicked one, landed on a website, and read the answer there.

That behaviour is changing. People now ask full questions and get a written answer straight back, often without clicking anything. They ask ChatGPT to recommend a supplier. They ask Perplexity to compare two products and cite its sources. They Google something and read Google’s own AI summary before they ever reach a website. This is what people mean by AI search: search experiences where an AI reads the web for you and hands back a composed answer instead of a page of links.

That single change is what all the new acronyms are trying to name.

What is AEO? Answer Engine Optimisation

Answer engine optimisation (AEO) is the practice of getting your business chosen as the direct answer inside AI assistants like ChatGPT, Perplexity and Gemini.

An “answer engine” is any tool that gives you a straight answer rather than a list of links. When someone asks one of these tools “who does SEO in Brisbane” or “what is the best CRM for a small trades business”, it picks a handful of sources, blends them, and produces one confident reply. AEO is about being the source it picks and the name it mentions.

So what is AEO in practice? It is making sure your content is clear, factual, well-structured and easy for a machine to quote. If an answer engine cannot understand what you do, it will reach for a competitor who made that easier.

What is GEO? Generative Engine Optimisation

Generative engine optimisation (GEO) is the practice of shaping how generative AI describes and cites your brand.

Generative AI is the technology behind tools that write answers from scratch, such as ChatGPT and Google’s AI features. GEO is less about a single answer box and more about the overall picture these systems hold of you: what they say your business does, which strengths they mention, whether they cite you as a trustworthy source, and whether they get your facts right.

So what is GEO? It is influencing the story the AI tells about you. If you have ever asked ChatGPT about your own company and winced at the answer, you have seen exactly the problem GEO sets out to fix.

What are AI Overviews?

AI Overviews are Google’s AI-generated summary that appears above the normal search results. You ask a question, and before the familiar list of links, Google writes a short answer and pulls facts from a few websites it trusts.

AI Overviews matter because they sit at the top of the most-used search engine in the country. If your page is one of the sources feeding that summary, you get visibility and credibility even when the user never scrolls. If it is not, a competitor is being quoted in the spot everyone reads first.

Why AEO and GEO are really one discipline

Here is the part the acronyms hide: AEO and GEO overlap by around 90 per cent. Chase them as two separate projects and you will do the same work twice.

Think about what each one asks of you. To be picked as the answer (AEO), your content needs to be clear, accurate, well-structured and trusted. To be described correctly and cited (GEO), it needs to be clear, accurate, well-structured and trusted. Same content, same facts, same signals of authority. The only real difference is which tool you look at when you measure the result.

That is why we treat all of this as one job rather than a menu of buzzwords. Our AI search optimisation service is built around that single idea: make your business the clearest, most credible source on the topics you want to be known for, and you win across ChatGPT, Perplexity, Gemini and Google’s AI Overviews at once.

How this relates to regular SEO

Fair question: is this just SEO with a new coat of paint? Not quite, and not entirely new either. The same foundations that help you rank in Google, being genuinely useful, technically sound and trusted, also help you get cited in AI answers. The emphasis shifts, though. AI search rewards clear, quotable statements, strong structure and demonstrable expertise more heavily than old keyword tactics ever did.

We cover where the two diverge in our guide to how GEO differs from traditional SEO. The useful mental model: SEO gets you ranked, AEO and GEO get you quoted, and the work behind all three overlaps far more than the acronyms suggest.

The takeaway

You do not need to master three new disciplines. You need to be the clearest, most trustworthy answer to the questions your customers ask, whether they are typed into Google or asked out loud to an AI assistant. AEO, GEO and AI search are simply different windows onto that one goal.

Frequently asked questions

What does AEO stand for?

AEO stands for answer engine optimisation. It is the practice of getting your business chosen as the direct answer inside AI assistants such as ChatGPT, Perplexity and Gemini, rather than just ranking in a list of links.

What is the difference between AEO and GEO?

They overlap heavily. Answer engine optimisation (AEO) focuses on being selected as the answer an AI gives, while generative engine optimisation (GEO) focuses on shaping how AI describes and cites your brand. In practice they rely on the same content and trust signals, so most businesses should treat them as one discipline.

Is AI search the same as SEO?

No, but they share the same foundations. SEO helps you rank in traditional search results, while AI search optimisation helps you get quoted and cited inside AI answers. Useful, well-structured, trustworthy content helps with both, so the work overlaps significantly.

Do I need to do AEO and GEO separately?

Generally no. Because AEO and GEO overlap by roughly 90 per cent, the smart approach is to run them as a single AI search optimisation effort rather than chasing each acronym on its own.
