Search isn’t just about ranking in a list of Google results anymore.

People are increasingly asking questions directly through Google AI, ChatGPT, Gemini, Perplexity and other AI-powered platforms and receiving an answer without necessarily working their way through ten traditional search results.

That change has led to growing interest in Answer Engine Optimisation (AEO).

But what exactly is AEO, how is it different from SEO and GEO, and does your business actually need to worry about another three-letter acronym?

AEO, or Answer Engine Optimisation, is the process of making your content and online presence easier for search and AI-powered answer engines to understand, trust and use when answering people’s questions.

In practical terms, traditional SEO aims to help your website appear prominently in search results. AEO goes further by helping your information become part of the answer itself.

I’ve worked in SEO and digital marketing for more than 15 years, and I don’t see AEO as the death of SEO or an entirely separate discipline.

Many of the foundations I’ve used for years — technically sound websites, useful content, clear site structure, authority, reputation and strong brand signals — still matter.

What’s changing is how that information is discovered, interpreted and presented to the person searching.

What Does AEO Stand For?

AEO stands for Answer Engine Optimisation.

An answer engine is a search or AI-powered system that attempts to answer a user’s question directly, rather than simply presenting a list of websites for the person to investigate themselves.

Depending on how broadly you use the term, examples can include:

• Google AI Overviews and AI Mode;
• ChatGPT search;
• Gemini;
• Perplexity;
• voice assistants;
• featured snippets and other direct-answer search experiences.

AEO therefore focuses on making your information suitable for these answer-driven experiences.

You might also hear terms such as AI SEO, AI search optimisation, GEO (Generative Engine Optimisation) and LLM optimisation.

The terminology is still evolving and there’s considerable overlap between them.

For a business owner, I wouldn’t get too hung up on the acronyms.

The important question is:

Can search engines and AI platforms understand your business and confidently use information about it when answering a relevant question?

How Does Answer Engine Optimisation Work?

Traditional search usually involves a person entering a query, seeing a list of results and deciding which website to visit.

Answer-driven search can behave differently.

Someone might ask:

“How much should I spend on SEO?”

“What’s the best CRM for a small business?”

“Recommend an SEO company in Ireland.”

“Which running shoes are best for beginners?”

The platform may then produce a direct response, sometimes using information gathered from multiple sources.

That changes what businesses are competing for.

You’re no longer thinking only about:

Can my page rank for this keyword?

You’re also thinking about:

Can my information contribute to the answer?

Can my business be mentioned?

Can my content be cited?

Could my company or product be recommended?

That is where AEO comes in.

AEO vs SEO: What’s the Difference?

SEO and AEO aren’t competing strategies.

They overlap heavily.

	SEO	AEO
Primary objective	Improve visibility in organic search	Improve visibility within direct answers
Typical outcome	Ranking/search result	Mention, citation or answer
Search behaviour	User searches and chooses a result	Platform may answer the question directly
Content focus	Search intent and topical relevance	Clear, useful and extractable answers
Technical foundations	Crawlability, indexability, site structure	Many of the same foundations
Authority	Links, reputation, expertise and relevance	Authority, corroboration, expertise and relevance
Measurement	Rankings, clicks, traffic, leads and sales	Mentions, citations, recommendations, visibility and referrals

The easiest way I explain it is:

SEO helps your content get found. AEO increases its chances of being used as part of an answer.

But I wouldn’t try to do the second while ignoring the first.

Strong SEO foundations remain incredibly important.

For Google’s own AI search experiences, Google says the same fundamental SEO best practices remain relevant, and pages need to be indexed and eligible to appear in Google Search before they can appear as supporting links in AI features.

So no, AEO hasn’t made SEO obsolete.

AEO vs GEO: What’s the Difference?

This is where the terminology gets particularly confusing.

AEO stands for Answer Engine Optimisation.

GEO stands for Generative Engine Optimisation.

AEO is generally framed around optimising information so it can be used within direct answers.

GEO is generally framed around improving visibility within generative AI responses.

For example:

	AEO	GEO
Full name	Answer Engine Optimisation	Generative Engine Optimisation
Focus	Becoming part of a direct answer	Visibility within generative AI responses
Potential surfaces	Search answers, AI answers, snippets and voice	ChatGPT, Gemini, Perplexity, Google AI and other generative systems
Potential outcome	Answer, mention or citation	Mention, citation or recommendation
Relationship with SEO	Builds on many SEO principles	Builds on many SEO principles

But I wouldn’t pretend there’s a perfectly defined line separating the two.

Even within the search industry, AEO and GEO are sometimes used interchangeably.

What matters more is understanding what you’re trying to achieve.

For most businesses, that’s going to be some combination of:

Google visibility + AI visibility + citations + brand mentions + recommendations + traffic + ultimately leads or sales.

SEO vs AEO vs GEO

If all these acronyms are starting to feel slightly ridiculous, you’re not alone. 😂

Here’s the simplest way to look at them.

	SEO	AEO	GEO
Optimising for	Search engines	Answer engines	Generative AI engines
Main goal	Rank and attract organic traffic	Become part of the answer	Appear within generated responses
Example	Ranking in Google	Being used in a direct answer	Being mentioned/cited by ChatGPT or another generative platform
Still needs good content?	Yes	Yes	Yes
Technical accessibility matters?	Yes	Yes	Yes
Authority matters?	Yes	Yes	Yes
Reputation/brand signals matter?	Yes	Increasingly relevant	Increasingly relevant

This is also why our approach at New Era Digital combines traditional SEO with AI SEO and GEO rather than treating them as three completely separate marketing channels.

The terminology might be new.

Many of the underlying principles aren’t.

Examples of AEO in Practice

Let’s make this less abstract.

Imagine someone asks:

“How much does SEO cost in Ireland?”

Traditional SEO might help my guide to SEO costs in Ireland rank prominently in Google’s organic results.

AEO could potentially help information from that guide become part of the answer itself.

Now consider:

“What is local SEO?”

A strong Local SEO resource might be surfaced or cited when an answer engine explains the concept.

Or:

“Recommend an SEO company in Ireland that works with small businesses.”

That’s slightly different again.

Now the user isn’t simply asking for information.

They’re asking for a recommendation.

This distinction matters.

Being Cited Isn’t the Same as Being Recommended

This is one of the most important things I think businesses need to understand about AEO.

Your website might be cited as the source of useful information without your business actually being recommended.

For example:

“According to New Era Digital, SEO costs depend on the scope and objectives of the campaign…”

That’s a citation.

Compare it with:

“New Era Digital is an Irish SEO agency specialising in SEO and AI search optimisation…”

That’s a brand mention.

And then:

“New Era Digital is one company you could consider…”

That’s a recommendation.

These are different AI visibility outcomes.

A business investing in AEO shouldn’t therefore measure success purely by asking:

“How many times were we cited?”

We also need to know:

Where are we being mentioned?

How are we being described?

Which topics are we associated with?

Are competitors being recommended instead?

Are we appearing for commercial discovery questions?

I’ve gone into this much further in my guide to how to get AI to recommend your business.

Why Is AEO Becoming Important?

The fundamental change is simple:

the answer itself is increasingly becoming the search experience.

Someone researching a product, service or problem may receive substantial information before visiting a website.

That doesn’t mean websites are disappearing.

It means businesses need to think about visibility more broadly.

For years, SEO professionals have measured things such as:

rankings → impressions → clicks → traffic → conversions.

AI search introduces additional visibility signals:

mentions → citations → recommendations → AI referrals → conversions.

For businesses, being visible at the point where someone is researching and comparing their options could become increasingly valuable.

How Do You Optimise for AEO?

There’s no magic AEO switch.

And I’d be extremely sceptical of anybody promising guaranteed placement in ChatGPT, Gemini or Google’s AI results.

Instead, I’d work through the fundamentals systematically.

1. Get Your SEO Foundations Right

Start with the website itself.

Can search engines crawl it?

Can important pages be indexed?

Does the site have a logical structure?

Can users navigate it easily?

Are your important products and services clearly explained?

Are pages internally linked?

Do you have useful content around the subjects you’re trying to become known for?

AEO shouldn’t become an excuse to ignore basic SEO.

2. Answer Questions Clearly

If someone asks:

What Is Answer Engine Optimisation?

Give them the answer.

Don’t spend eight paragraphs telling them how much the world has changed before defining the thing they searched for.

A strong answer might start:

Answer Engine Optimisation (AEO) is the process of improving content so answer-driven search and AI systems can understand and potentially use it when responding to a user’s question.

Then expand on it.

Clear content doesn’t have to mean simplistic content.

It means the reader can find the information they came for.

3. Structure Content Properly

Good page structure helps both users and machines understand how information relates.

Use:

• descriptive headings;
• logical sections;
• concise definitions;
• relevant tables;
• lists where useful;
• clear examples;
• supporting evidence;
• FAQs where they genuinely add value.

But don’t turn every article into a robotic collection of 50-word Q&As because somebody told you that’s how to “rank in ChatGPT”.

The content still needs to be genuinely useful to a human reader.

4. Demonstrate Real Experience

This is one of the biggest opportunities businesses have.

AI can summarise information incredibly quickly.

What it can’t manufacture is your genuine first-hand experience.

I’ve spent more than 15 years working directly with SEO clients.

That means I can talk about what I’ve actually seen work, where businesses waste money, how SEO strategies change as companies grow and why the right strategy for one business can be completely wrong for another.

A manufacturer, accountant, retailer, physiotherapist or SaaS founder has their own equivalent experience.

Put that into your content.

Your website shouldn’t simply repeat what everybody else’s website already says.

5. Build Topical Depth

If you want to become associated with a subject, one superficial page usually isn’t enough.

Build useful content around the real questions within your area of expertise.

For New Era Digital, for example, AI search content might include:

AI SEO → AEO → GEO → AI visibility → ChatGPT visibility → AI recommendations → measuring AI visibility.

Those subjects naturally reinforce one another.

This is very different from publishing hundreds of loosely related articles simply because a keyword research tool says they have search volume.

6. Strengthen Your Brand Signals

Your website shouldn’t leave people — or search systems — guessing who you are.

Make important relationships clear:

brand → people → expertise → services → products → industries → locations

For example, across my own website I want it to be clear that:

Sarah Jane Vincent → New Era Digital → SEO → AI SEO & GEO → Ireland.

That relationship shouldn’t rely on one sentence on one page.

It should be supported naturally throughout the wider digital footprint of the business.

7. Earn Relevant Third-Party Mentions

What you say about yourself matters.

What other credible sources say about you can matter too.

Relevant third-party signals might include:

• industry publications;
• professional organisations;
• genuine reviews;
• expert contributions;
• podcasts;
• interviews;
• partnerships;
• relevant directories;
• news coverage;
• backlinks;
• independent brand mentions.

This isn’t permission to start buying hundreds of questionable directory links.

The emphasis should be on relevance and credibility.

8. Build Genuine Reviews and Reputation

If someone asks an AI platform:

“Which company would you recommend?”

reputation becomes relevant to that question.

Encourage genuine customers to review their experience on appropriate platforms.

And useful reviews aren’t simply:

“Excellent service. Five stars.”

Reviews explaining what the customer needed, what the business provided and what happened afterwards provide much richer context.

9. Use Structured Data Appropriately

Structured data can help search engines understand particular information on a page and make content eligible for certain search features.

Use it where it’s appropriate.

But don’t assume adding schema means you’ve “done AEO”.

Google specifically states that no special schema or structured data is required for its AI features.

Your structured data should accurately represent what’s visible on the page.

Schema supports good content. It doesn’t replace it.

10. Make Sure Your Content Can Be Accessed

This sounds obvious, but it’s worth checking.

If you want your content to appear in search or AI-powered discovery, relevant systems need to be able to access it.

For Google AI features, Google’s normal crawling and indexing requirements continue to apply.

For ChatGPT search, OpenAI recommends allowing OAI-SearchBot if you want your website content to be discovered, surfaced and cited.

So crawler accessibility is one of the technical areas I would include when assessing a site’s AI visibility.

Does AEO Require Special Schema, AI Files or Plugins?

No single plugin turns a website into an “AEO-optimised” website.

There also isn’t a special piece of schema that guarantees AI visibility.

That matters because whenever a new area of search emerges, an industry quickly appears around selling shortcuts.

Technical optimisation absolutely matters.

But AEO is much broader than installing a plugin.

You still need:

useful information + accessibility + relevance + authority + reputation + clear brand signals.

I’d concentrate on those before hunting for a magic AI optimisation button.

Does AEO Help You Appear in ChatGPT?

Potentially, yes — but there is no guarantee that optimising a page will cause ChatGPT to cite or recommend it.

OpenAI says that public websites can appear in ChatGPT search and recommends allowing OAI-SearchBot so content can be discovered and surfaced.

But technical accessibility is only part of the picture.

You still need content worth surfacing in the first place.

That’s why I wouldn’t reduce “ChatGPT SEO” to editing robots.txt.

How Do You Measure AEO?

This is where AEO becomes much more useful as an actual marketing discipline.

Establish a baseline.

Create a representative set of questions your potential customers might ask.

Then monitor things such as:

Metric	What you’re looking for
AI mentions	Does your brand appear?
Citations	Is your website being used as a source?
Recommendations	Is your business actually suggested?
Brand accuracy	Is the information about your business correct?
Topic association	What subjects are you associated with?
Competitor visibility	Which competitors appear instead?
AI referral traffic	Are people reaching your site from AI platforms?
Conversions	Is that visibility contributing to enquiries or sales?

This distinction between citation visibility and recommendation visibility is particularly important. Current AEO research and industry guidance increasingly treat them as separate outcomes rather than one generic “AI ranking”.

Ultimately, I don’t want a client celebrating because their company was mentioned by ChatGPT 14 times if those mentions aren’t relevant to the commercial objectives of the business.

Visibility needs context.

Common AEO Mistakes

Some of the mistakes I’m already seeing are surprisingly familiar.

Treating AEO as completely separate from SEO

You don’t need to throw away 20 years of search principles because AI arrived.

Creating generic AI content at scale

Publishing hundreds of articles that say exactly the same thing as everybody else’s isn’t a meaningful authority strategy.

Focusing only on your own website

Your wider reputation and digital footprint matter too.

Measuring citations but ignoring recommendations

Being quoted isn’t necessarily the same as being commercially visible.

Chasing every new AEO hack

A new file, plugin or schema type isn’t automatically the missing ingredient.

Forgetting the customer

We’re still ultimately trying to help a person make a decision.

That’s the bit I’d keep at the centre of all of this.

Is AEO Replacing SEO?

No.

I see AEO as an extension of modern SEO rather than its replacement.

Search is broadening.

Businesses now need to think about visibility across traditional Google results, Google’s AI experiences and independent AI platforms.

But the fundamentals haven’t suddenly disappeared.

You still need a website that works.

You still need useful content.

You still need authority.

You still need relevance.

You still need reputation.

And you still need to understand what your customers are searching — or asking — for.

SEO isn’t dying. The places where search happens are expanding.

Frequently Asked Questions About AEO

What is AEO in SEO?

AEO stands for Answer Engine Optimisation. It focuses on making information easier for answer-driven search and AI platforms to understand and potentially use within direct answers. It overlaps heavily with SEO and should generally build on strong SEO foundations rather than replace them.

What is AI engine optimisation?

You’ll sometimes see people use “AI engine optimisation” when discussing AEO, although Answer Engine Optimisation is the established meaning of AEO within search marketing. Related terms include AI SEO, GEO and AI search optimisation.

How do you optimise for answer engines?

Start with strong technical SEO, answer relevant questions clearly, structure information logically, demonstrate first-hand expertise, build topical depth, strengthen your brand and reputation, and earn credible third-party mentions.

There isn’t one AEO tactic that guarantees visibility.

What’s the difference between AEO and GEO?

AEO generally focuses on becoming part of a direct answer, while GEO focuses specifically on visibility within generative AI responses. In practice, the disciplines overlap considerably and the terms are sometimes used interchangeably.

What’s the difference between SEO and AEO?

SEO traditionally focuses on improving a website’s visibility within organic search results. AEO focuses on increasing the likelihood that information is used within a direct answer. Many of the underlying optimisation principles overlap.

Does AEO work for small businesses?

Yes. AEO isn’t limited to large brands.

A small business with genuine expertise, strong local relevance, useful content, good reviews and a credible digital presence can have valuable information to contribute to answer-driven search.

The strategy should reflect the business, its audience and its commercial goals.

Can AEO get my business recommended by ChatGPT?

AEO can improve the information and signals surrounding your business, but it cannot guarantee a ChatGPT recommendation.

If that’s your objective, read my complete guide to getting AI to recommend your business.

What Does AEO Mean for Your Business?

I wouldn’t panic about AEO.

And I definitely wouldn’t abandon your existing SEO strategy because somebody told you traditional search is dead.

Instead, broaden how you think about search visibility.

Ask:

Can people find us in Google?

Can search and AI systems understand what we’re known for?

Are we publishing genuinely useful information?

Does the wider web support what we say about ourselves?

Are AI platforms citing or mentioning us?

Are we being recommended when potential customers ask for businesses like ours?

That’s where SEO, AEO and GEO start to come together.

The acronyms matter far less than the commercial objective:

making sure your business can be found and understood wherever your potential customers are searching for answers.

At New Era Digital, our AI SEO and GEO services combine established SEO principles with AI search optimisation to help businesses strengthen their visibility across Google and emerging AI-powered search experiences.
