AEO, GEO & AI Search

SEO, AEO and GEO Explained: What Changes With AI Search

What Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) mean, how they overlap with traditional SEO, what Google itself says about them, and which practices are worth your time.

Last reviewed: 14 October 2026

Search is no longer just a list of ten blue links. People get direct answers in search results, ask AI assistants questions and read AI-generated summaries with links to sources. Two new terms have become popular to describe optimising for this: AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization). This article explains what they mean, how they relate to SEO and where to focus your effort.

Quick definitions

Term	Short meaning	Typical focus
SEO (Search Engine Optimization)	Helping people find your content through search engines	Crawlable, indexable, helpful pages that match search intent
AEO (Answer Engine Optimization)	Making content easy to use as a direct answer	Clear questions and concise answers, featured snippets, voice and assistant answers
GEO (Generative Engine Optimization)	Increasing the chance that AI-generated answers mention or link to your content	Original, trustworthy information that AI systems can find and cite

AEO and GEO are industry terms, not official standards. Different agencies use them in slightly different ways, and there is no official checklist from search engines for either.

What Google says

Google published a guide on optimising for its generative AI features in Search in May 2026. Its message is clear: the best practices for SEO continue to apply, because AI Overviews and AI Mode are built on Google’s core ranking and quality systems. Google describes optimising for these features as part of SEO, rather than a separate discipline.

The same guide and Google’s documentation on AI features say that:

There are no special requirements to appear in AI Overviews or AI Mode. A page needs to be indexed and eligible to be shown with a snippet.
You do not need special AI text files (such as llms.txt), special markup or Markdown versions of pages for Google Search.
There is no need to break content into tiny chunks or to write in a special style only for AI.
Original, non-commodity content helps: Google encourages content based on your own knowledge and experience rather than repeating what is already widely available.
Producing many pages to target query variations can breach Google’s scaled content abuse policy.

Other AI search products, such as AI assistants with web search, publish their own guidance and may work differently. Treat any claim about how a particular AI system chooses sources as a hypothesis unless the provider documents it.

Where SEO, AEO and GEO overlap

In practice, most of the work is the same:

Be findable. Pages must be crawlable and indexable. See how search engines crawl, index and rank pages.
Match intent. Answer the question people are actually asking. See what search intent is.
Answer clearly. Put the direct answer early, then add detail. See how to write answer-first content.
Be trustworthy. Show who is behind the content, cite sources and offer genuine experience or data. See entities, E-E-A-T and original information.
Be the best source on your topic. AI answers often cite pages that explain something well or provide information that is hard to find elsewhere.

Where they differ

The differences are mainly in what success looks like and how you measure it:

SEO has well-established measurements: impressions, clicks and rankings in Search Console.
AEO success might be appearing as the quoted answer for a question, or being read out by a voice assistant. These are harder to track consistently.
GEO success might be being mentioned or linked in an AI-generated answer. Visibility can vary between users and over time, and many AI tools give limited reporting. See how to measure AI search visibility.

Practices to be careful with

Some advice sold under the AEO or GEO label is unproven or risky:

Creating hundreds of pages for every question variation. This can be scaled content abuse.
Seeking fake mentions, reviews or “citations” on other sites. Google’s guide notes that seeking inauthentic mentions is not as helpful as it may seem, and fake reviews break platform policies.
Hidden text or prompts aimed at AI systems. Content should be written for people.
Paying for tools that promise guaranteed inclusion in AI answers. No one outside the search companies controls their ranking or AI systems.

A practical plan for 2026–2027

For a student or a small business, a sensible order of work is:

Fix technical basics: indexing, mobile usability, page speed.
Choose topics with clear intent and real value for your audience.
Write answer-first pages with your own examples, data or experience.
Make your business identity consistent: website, Google Business Profile and social profiles.
Earn genuine mentions and links through useful work, not through manipulation.
Measure what you can (Search Console, analytics, enquiries) and treat AI visibility tracking as directional.

Common questions

Is SEO dead because of AI search?

No. Google states that its AI features rely on its core ranking and quality systems, and that SEO best practices continue to apply. What changes is how results are presented and how some people search, so clear, original and trustworthy content becomes even more important.

Should a small business hire a separate “GEO agency”?

Be cautious. The core work (technical health, helpful content, a strong Google Business Profile and genuine reputation) is the same as good SEO. Ask any provider exactly what they will do, how they will measure it and what they cannot control.

Do AEO and GEO apply to ChatGPT, Perplexity and other assistants too?

The general principles of being findable, clear and trustworthy apply widely, but each product works differently and publishes its own guidance. Treat claims about how a particular assistant chooses sources as hypotheses unless the provider documents them.
