Is GEO just a new name for AEO?

Mostly. GEO came out of a 2023 research paper on optimising content for generative engines; AEO is the older, broader term that also covers voice assistants and featured snippets. Today both point at the same goal: being named or cited in AI-generated answers.

Will AEO replace SEO?

No. Answer engines retrieve and cite web pages, and Google's AI Overviews use the same index as regular search. Pages that rank well are the pages most likely to be read by an engine. AEO adds a measurement layer on top of SEO; it does not remove the foundation.

Do I need different content for AEO than for SEO?

Usually the same pages with a different shape: the answer first, clear definitions, comparison tables, an FAQ block. Content that is good for a featured snippet is close to what an answer engine wants to quote.

Which should a small team focus on?

Keep the SEO basics running, because they feed everything else, and start measuring AEO now while your category is uncontested in the answers. Measurement costs an hour a week; it tells you whether anything else is worth doing.

SEO vs. AEO vs. GEO: What's the Difference?

SEO, AEO and GEO are related but distinct. This guide breaks down each term, how they overlap, and where to focus your effort in 2026.

The acronyms are multiplying, and the definitions online contradict each other. Here is a plain breakdown of SEO, AEO and GEO: what each one means, where they overlap, where they genuinely differ, and where a small team should put its hours in 2026.

SEO: Search Engine Optimization

The original discipline. SEO is the work of earning a position on a search results page: technical health so the crawler can read the site, content that matches what people search for, and links and mentions that tell the engine the site is worth ranking.

Its unit of success is a page ranking for a keyword, and its measurement is a position you can check every day with a rank tracker. The results page has changed shape many times, with ads, snippets, maps and now AI Overviews on top, but the core loop of crawl, index, rank has not.

SEO is still essential for one reason that matters to everything below: the pages answer engines read and cite are, overwhelmingly, pages that already rank. Strong SEO is the raw material of AEO.

AEO: Answer Engine Optimization

AEO is the work of being named and cited inside a generated answer: the paragraph ChatGPT writes, the Gemini response, the Perplexity summary, the Google AI Overview above the organic results. The unit of success shifts from "ranking a page" to "being the answer", or at least one of the two or three names in it.

The term predates the current wave. It was first used for featured snippets and voice assistants, where the engine also returned one answer rather than a list. What is new is scale: answer engines now handle the research and comparison questions that used to send buyers to ten blue links.

AEO has its own measurement, and this is the part most guides skip. There is no position. There is a mention rate (how often you are named across a fixed set of prompts), a citation rate (how often your site is linked as a source) and a share of voice against the competitors named alongside you. Each of those is tracked per engine, because the engines disagree. Our complete guide to AEO goes through the measurement in detail.

GEO: Generative Engine Optimization

GEO is the youngest term. It comes from a 2023 academic paper, GEO: Generative Engine Optimization, which tested which content changes made a page more likely to be included in a generative engine's answer. The paper's framing stuck: optimise your content for how a generative model synthesises sources into a response.

In practice, GEO emphasises the content side. Cite sources, include statistics, use clear definitions, write with authority, structure for quotation. AEO, as most people use it, covers the whole goal, including the measurement and the off-site corroboration that gets a brand named at all.

The honest summary: AEO and GEO describe the same goal from slightly different angles. Choose one term for your team and do not spend a meeting on the difference.

How the three compare

	SEO	AEO	GEO
Target	Ranking algorithms	Answer engines (ChatGPT, Gemini, Perplexity, AI Overviews)	Generative models specifically
Goal	Rank a page	Be named or cited in the answer	Be included in the synthesised response
Unit of success	Page + keyword	Brand + prompt	Content + prompt
Success metric	Position, clicks	Mention rate, citation rate, share of voice	Inclusion in the response
Content style	Keyword-aligned pages	Clear, factual, citable answers; consistent entity	Cited, statistic-rich, quotable passages
Where measured	Rank tracker	Prompt tracker, per engine	Same as AEO

Where they overlap

The same pages do the work

An answer engine that searches the web reads pages, and it tends to read the ones that rank. Google says as much in its documentation on AI features and your website: there is no special markup for AI Overviews, and the usual guidance applies. Technical SEO, crawlability and page quality are shared foundations.

Clear content wins in both

A page that answers the question in its first sixty words, uses headings that are questions, and puts comparisons in a table does well in featured snippets, in AI answers and with human readers. The same is true of a real FAQ block with real answers. You rarely have to choose between writing for search and writing for answers.

Authority is authority

Links, reviews, directory listings and mentions on trusted sites tell a ranking algorithm the page matters, and they tell an answer engine the brand is real and worth naming. The channels overlap almost completely; only the accounting differs.

Where they genuinely differ

Page versus entity

SEO is won page by page. A great page can rank even if the rest of your presence is thin. AEO is won at the entity level: the engine is deciding whether to name your brand, and it draws on everything it can find about you. A brilliant page will not get you named if your directory listings call you something else and your reviews are three years old.

Position versus rate

An SEO position is a fact you can check at any moment. An AEO mention is a probability: the same prompt can produce different names on different days, so you measure it as a rate over repeated runs. One check is a screenshot, not a measurement.

One engine versus several

For most sites SEO means Google, with Bing a distant second. AEO means at least four engines that disagree with each other, refreshed on different schedules from different sources. A brand that ChatGPT recommends can be absent from Gemini for the same question. You can see how the engines differ on our ChatGPT tracker, Gemini tracker and AI Overviews tracker pages.

Where to focus in 2026

Do not abandon SEO. It feeds the answer engines and it is still where most measurable traffic comes from.

Do start measuring AEO now, because it is the number most brands are flying blind on. Measurement is cheap: a fixed list of twenty to fifty buyer prompts, a weekly check on the engines your buyers use, and three columns per prompt (named, cited, who else). Our walkthrough on how to track whether your brand appears in ChatGPT shows the routine.

Then judge every new tactic by which number it moves. If it improves rankings, it is SEO and you already know how to run it. If it improves your mention rate or share of voice, it is AEO, whatever the article that recommended it called it.

You cannot optimise what you cannot see. That is the problem Presence Scout exists to solve: continuous measurement of your brand across Google and the AI answer engines, so your SEO, AEO and GEO work all have a number to move. Add your brand free and get your first baseline this week.
