SEO, AEO and GEO: What They Are, and Why Getting Ahead Now Is the Advantage
People used to find businesses by typing a few words into Google and clicking a blue link. A lot of them still do. But a growing number now ask a question out loud, or type a full sentence into an AI tool, and get a straight answer without ever scrolling through a results page.
That shift has created three different ways of being found. SEO, AEO and GEO. Here is what each one means, how they differ, and why the businesses acting on them now will be the ones getting chosen later.
What is SEO?
Search Engine Optimisation is the practice of getting your website to rank as high as possible on a search results page like Google or Bing. The higher you rank, the more people click, the more customers you get.
It works through useful content, the right keywords, a fast and well-built website, and links from other reputable sites pointing back to you.
What is AEO?
Answer Engine Optimisation is the practice of getting your content chosen as the single answer to a question, rather than one option in a list.
This is the snippet that sits above the normal search results. It is also the voice that reads a reply back when someone asks their phone or smart speaker a question. With AEO, you are not competing to be clicked. You are competing to be the answer.
What is GEO?
Generative Engine Optimisation is the practice of getting your business surfaced and recommended inside AI tools like ChatGPT, Claude, Perplexity, Gemini and Google’s AI overviews.
When someone asks one of those tools to recommend a supplier, an agency or a product, GEO influences whether your name appears in the answer. It is the newest of the three, and the one most businesses have not started yet.
What is the difference between SEO, AEO and GEO?
The simplest way to think about it:
| What you are aiming for | Where it shows up | |
|---|---|---|
| SEO | To be in the list | Search results pages |
| AEO | To be the answer | Featured snippets and voice assistants |
| GEO | To be the recommendation | AI-generated answers |
SEO gets you found. AEO gets you read out. GEO gets you recommended. They overlap, but they are not the same job, and the clearest, most credible businesses are the ones that tend to win at all three.
What are the pros and cons of each?
SEO. It is mature, measurable, and a huge amount of buying still starts with a search. Done well, it compounds over time. The downside is that it is slow to build, highly competitive, and Google increasingly answers questions itself, so your ranking can be strong while your traffic still falls.
AEO. Being the answer positions you as the authority and captures fast-growing voice search. The downside is that it often means no click. The engine uses your answer and the person never reaches your site, so you gain credibility but not always traffic, and it is harder to measure.
GEO. It is a genuine first-mover opportunity, it reaches buyers while they are shortlisting, and an AI recommendation carries a sense of neutrality that feels like trust. The downside is that it is new and less predictable, you do not fully control how you are described, and there is no settled playbook yet.
When should you use each?
Use SEO always. It is the foundation everything else sits on. If your website is a mess, the smarter engines have nothing good to work with either.
Use AEO when your customers ask clear, specific questions and you want to own the answer to those questions in your field.
Use GEO when your buyers research before they buy, which covers almost every considered purchase, and especially in B2B. If someone is about to spend real money with you, they are probably checking with AI first.
How do you rank higher in each?
SEO. Write content that genuinely answers what people search for. Keep your site quick and easy to crawl. Earn links from sites people trust. Prove real expertise, because that is what gets rewarded.
AEO. Answer questions directly and early. Use the actual question as a heading. Keep content clear and scannable. Add structured data so engines understand exactly what your content is. Write the way people speak.
GEO. Make it crystal clear who you are and what you do, in plain language, across as many places online as possible. AI builds a picture of you from everything it can find, so consistency matters. Earn mentions on sites AI already trusts. Use structured data. Write factual, quotable statements that are easy to cite. Build genuine authority on your topic.
Why does this matter now?
Because these engines are forming their understanding of your business today. The brand AI recommends in eighteen months is the one that gave it clear, consistent, credible information now.
This is the part that gets missed. Brand clarity is no longer a nice-to-have. If you cannot explain in plain terms who you are, who you help and why you are the right choice, a human might give you the benefit of the doubt. An AI will not. It will simply pick the business that made itself easy to understand.
So the real work is not chasing three sets of rules. It is being clear enough that all three engines, and the people behind them, can confidently choose you. The businesses that get this now will spend the next few years being recommended. The ones that wait will spend those years wondering why the enquiries dried up.

Frequently Asked Questions
Is SEO dead?
No. SEO is still the foundation, and most online buying still begins with a search. What has changed is that it is no longer the whole game. AEO and GEO now sit alongside it.
Do I need to choose between SEO, AEO and GEO?
No. They reinforce each other. Strong, well-structured, credible content tends to perform across all three at once, which is why clarity matters more than picking a single tactic.
What is the difference between AEO and GEO?
AEO is about being the direct answer in search engines and voice assistants. GEO is about being recommended inside generative AI tools like ChatGPT and Perplexity. Related goals, different engines.
How do I get my business mentioned by AI?
Be clear and consistent about who you are and what you do across the web, earn mentions on trusted sites, use structured data, and build genuine authority on your topic. AI surfaces the businesses it can understand and trust.
