Search is changing.
For years, the objective of SEO was fairly straightforward: understand what people search for, create the best possible pages around those searches and improve their visibility in Google.
That still matters. A lot.
But people are increasingly getting answers without following the traditional search journey.
Google can generate an AI Overview directly within the results. ChatGPT can recommend businesses, products and sources in response to a question. Other AI-powered search tools can research a topic, compare options and summarise information without presenting ten blue links first.
That is where AEO comes in.
It is the process of making your website, content and wider brand easier for search engines and AI systems to understand, trust and use when producing direct answers.
Traditional SEO asks:
How do we get this page to rank?
AEO adds another question:
How do we make our business or content one of the sources used to create the answer?
That distinction is becoming increasingly important.
The simplest AEO meaning is Answer Engine Optimisation.
An answer engine is a platform that tries to answer a user’s question directly rather than simply giving them a list of websites to investigate themselves.
Google has been moving in this direction for years through featured snippets, knowledge panels, People Also Ask results and other search features.
Generative AI has accelerated it.
A search such as:
“What’s the best CRM for a small B2B company?”
may once have produced a traditional page of links.
Today, an AI-powered search experience might compare several providers, explain their strengths and weaknesses and recommend particular products within the answer itself.
That changes the opportunity for businesses.
Ranking still matters, but being understood, trusted and referenced matters too.
No.
And businesses making that assumption could end up damaging their search strategy.
AEO is better understood as an extension of modern SEO rather than a replacement for it.
Search engines and AI platforms still need reliable information to work from. Websites still need to be crawlable. Content still needs to match search intent. Brands still need authority. Pages still need links. Search engines still need to understand what a business does and why it should be trusted.
Strong SEO therefore creates much of the foundation needed for strong AEO.
The difference is that the end result is no longer limited to ranking a webpage.
Your information could also contribute to an AI-generated answer, recommendation, comparison or summary.
That means the strongest strategy isn’t SEO or AEO.
It’s building a search presence capable of performing across both.
There is currently a lot of terminology flying around the search industry.
SEO, AEO, GEO, AI SEO and LLM optimisation are often used almost interchangeably, which isn’t particularly helpful.
There is overlap, but the concepts are slightly different.
SEO improves a website’s ability to appear in traditional organic search results.
The objective might be ranking a service page for a commercial search, growing traffic to an article or improving visibility in local search.
AEO focuses on making information easy for search and AI systems to interpret and use when answering questions.
It is particularly relevant to featured answers, AI-generated responses and question-led searches.
GEO generally refers to improving visibility specifically within generative AI search experiences and large language model-powered tools.
In reality, businesses shouldn’t become obsessed with which acronym wins.
The practical objective is much simpler:
Make your brand exceptionally easy to discover, understand, verify and recommend wherever people search.
The traditional search journey has become less predictable.
Someone researching software might start with Google, continue the research through an AI assistant, read a Reddit discussion, visit comparison websites and only then reach a supplier.
Another person might ask an AI platform for three recommendations and never perform a conventional Google search at all.
This creates a much wider search ecosystem.
Businesses therefore need visibility beyond their own webpages.
Search engines and AI systems look for signals that help them understand:
Who is this business?
What does it specialise in?
Which subjects does it have genuine expertise in?
What evidence supports its claims?
Who else mentions it?
Is its information consistent?
Does its content actually answer the question being asked?
AEO is about strengthening those signals.
There isn’t one universal formula.
Different search engines and AI platforms use different systems, indexes, retrieval methods and ranking signals.
However, there are some principles that consistently make information easier to understand and surface.
The content has to be accessible, the subject needs to be clear and claims should be supported.
The brand needs some level of authority around the topic.
The information should directly address the user’s question.
And ideally, the same expertise should be reinforced elsewhere on the web rather than existing only because a company says it is an expert on its own website.
This last point is particularly important.
You can publish a page saying you’re the UK’s greatest SaaS SEO agency tomorrow.
That doesn’t make it true.
But if your website contains substantial SaaS expertise, clients reference your work, industry publications mention you, other websites cite your research and independent sources associate your brand with SaaS SEO, an entirely different picture starts to emerge.
That wider evidence matters in modern search.
AEO isn’t about adding the phrase “answer engine optimisation” twenty times to a page.
It is about structuring your website and wider search presence so machines can understand it while still creating something genuinely useful for humans.
Some of the most important areas are:
The common theme is clarity.
If humans struggle to understand what a page is saying, machines probably aren’t going to find it particularly useful either.
This is where a lot of businesses will get AEO wrong.
The temptation will be to generate hundreds of articles answering every remotely relevant question.
That might increase the number of pages on a website.
It does not automatically increase authority.
If every competitor publishes essentially the same AI-generated explanation of “What is AEO?”, search engines have little reason to value one above another.
Originality becomes increasingly valuable.
A strong article might include real search examples, proprietary data, testing, screenshots, expert opinions, customer questions or evidence from actual campaigns.
Instead of simply explaining what something means, it should add something.
That is one reason our approach to AI SEO focuses on the wider search ecosystem rather than simply publishing more content.
Traditional SEO has always involved authority.
AEO makes the wider picture even more interesting.
Imagine an AI platform researching the best companies within a particular market.
It may encounter a company’s own website, but it could also encounter reviews, news coverage, industry directories, comparison websites, Reddit conversations, interviews, case studies, social profiles and independent articles.
Those third-party signals provide context.
That means modern search visibility cannot be built exclusively on your own domain.
Businesses need a recognisable footprint.
For an SEO agency, for example, we’d rather have genuine client results, mentions from recognised marketing publications, independent reviews, interviews and respected websites discussing our work than 500 meaningless backlinks placed purely to manipulate a metric.
The first group helps establish a real entity.
The second mostly creates numbers inside an SEO tool.
Yes, but the objective is broader than simply increasing authority metrics.
A relevant backlink can help a page rank.
But the context surrounding that backlink also matters.
If respected websites consistently associate a company with a particular subject, that contributes to a much stronger digital footprint around the topic.
This is why good digital PR, editorial coverage and specialist link building fit naturally into an AEO strategy.
A backlink from an authoritative article discussing the exact field in which your business operates can potentially achieve several things at once.
It can generate referral traffic, improve traditional organic performance, reinforce topical relevance and increase the number of independent sources connecting your brand with that subject.
Potentially, yes.
But nobody can guarantee placement inside an AI-generated answer.
AI results are dynamic and can differ depending on the platform, wording of the question, available information and numerous other factors.
That makes promises such as “we’ll rank you #1 in ChatGPT” questionable at best.
A more credible objective is to increase the likelihood that AI systems can discover, understand and trust your business.
That means improving the underlying signals they have available.
Those fundamentals give a search platform considerably more to work with.
AEO isn’t only relevant to informational questions.
Some of the most commercially valuable searches are moving towards recommendation-based results.
Consider questions such as:
“Who are the best SEO agencies for SaaS companies?”
“Which accounting software is best for a small business?”
“What are the alternatives to HubSpot?”
“Which CRM integrates with Xero?”
“Who is the best commercial cleaning company in Wilmslow?”
These aren’t simply informational searches.
There is purchasing intent behind them.
If an AI platform becomes part of that recommendation process, businesses need to think about more than whether their homepage ranks for a traditional keyword.
They need to consider whether the wider web provides enough evidence for the brand to be recommended at all.
This is still developing.
There isn’t currently one perfect equivalent of traditional keyword rank tracking for every AI platform.
Businesses should therefore look at a combination of indicators.
Traditional organic rankings still matter.
So do impressions, clicks and query growth within Google Search Console.
But we’d also monitor branded search demand, third-party mentions, citations, referral traffic, visibility across relevant AI platforms and whether specific brands or webpages are appearing when commercially important questions are asked.
Over time, tooling around AI visibility will become more sophisticated.
For now, the biggest mistake would be waiting for measurement to become perfect before doing anything.
The fundamentals required for AEO are valuable regardless.
Businesses shouldn’t abandon proven SEO activity because a new acronym has appeared.
But they should understand how customer discovery is changing.
If people increasingly use AI systems to research products, compare suppliers and make decisions, appearing within those environments will become commercially important.
The best response isn’t panic. It’s building a stronger search presence, create information worth referencing, make your expertise obvious and strengthen your website.
Build genuine authority and earn third-party validation.
And make it easy for both humans and machines to understand exactly why your business deserves consideration.
That is Answer Engine Optimisation.
The way people search is changing, but the fundamental requirement hasn’t.
Businesses still need to become the most credible answer to the questions their customers are asking.
Sometimes that answer will appear as a traditional Google result sometimes it will appear in an AI Overview. Sometimes it could be surfaced through an AI assistant.
The objective is therefore bigger than chasing one ranking position.
It is about building enough search authority that your brand becomes difficult to ignore.

AEO stands for Answer Engine Optimisation. It involves improving content and brand signals so search engines and AI-powered platforms can more easily understand, trust and use information when answering user questions.
AEO is an extension of traditional SEO focused specifically on visibility within direct answers and AI-powered search experiences. SEO remains important because many of the signals that support organic rankings also help platforms discover and understand information.
SEO primarily focuses on improving visibility within organic search results. AEO focuses on increasing the likelihood that information is used within direct answers generated by search engines or AI systems. In practice, the two disciplines overlap heavily.
AEO generally refers to optimising for answer-based search experiences, while GEO, or Generative Engine Optimisation, tends to focus specifically on generative AI systems. The terminology is still developing and there is significant overlap between the two.
No. Strong technical SEO, content, authority and website structure remain important. AEO builds on those foundations rather than replacing them.
No credible agency should guarantee specific placement within dynamic AI-generated answers. The aim is to strengthen the signals that make a business easier for search and AI platforms to discover, understand and trust.
Potentially, yes. Consumers increasingly use conversational and recommendation-based searches when looking for local services. Strong local SEO, reviews, business information and third-party mentions can therefore form part of a wider AEO strategy.
There isn’t a universal timeframe. Existing authority, website quality, competition, content, technical foundations and third-party visibility all influence progress. AEO should usually be treated as part of a longer-term organic search strategy rather than a standalone quick fix.
AI discoverability describes how easily AI-powered search tools and assistants can find, understand and surface information about your business. This could result in your brand being mentioned, your website being cited or your company being recommended when users ask relevant questions.
Start by making sure your public content is accessible and useful. OpenAI recommends allowing OAI-SearchBot if you want site content to be available for summaries, citations and links in ChatGPT Search. Beyond crawler access, your website should clearly explain what your business does and provide relevant information that can answer the types of questions users are asking.
AI visibility can be assessed using a combination of Google Search Console’s generative AI reports, prompt monitoring across AI platforms, citation and mention tracking, competitor comparisons and analytics referral data. No single metric provides a complete picture.
They overlap, but they describe slightly different ideas. Generative Engine Optimisation, or GEO, refers to practices intended to improve visibility within generative search experiences. AI discoverability describes the broader ability of a business or its content to be found, understood and surfaced by AI systems.
Not for Google. Google currently states that llms.txt is not required for its generative search features and does not improve or harm visibility in Google Search. Other platforms may choose to support different standards, so requirements should be reviewed individually rather than treating llms.txt as a universal AI SEO requirement.
No. AI responses are generated dynamically and can vary according to the platform, prompt, context and information available. Businesses can improve the conditions that support discoverability and monitor how visibility changes, but no legitimate agency can guarantee that a particular AI system will consistently recommend a specific company.
