SEO, AEO and GEO: what is actually different

Three acronyms, sold as three services. Two of them describe almost the same job, and the third never went anywhere. Here is the version without the sales pitch.

The one line version

If you read nothing else, read this table.

Discipline	What it optimises for	Where you see it	What it needs from you
SEO	Ranking in a list of results	Blue links, the map pack	Pages worth ranking, technical health, links pointing at you
AEO	Being lifted out as the direct answer	Featured snippets, AI Overviews, voice replies	Question-shaped headings, short direct answers, structured data
GEO	Being cited inside a generated answer	ChatGPT, Gemini, Perplexity, Copilot	Facts, figures, named sources, and other websites describing you correctly

Why SEO did not die, it changed jobs

The numbers look like an obituary. In the first four months of 2026, 68.01% of Google searches in the United States ended without a single click, up from 60.45% in 2024. AI Overviews appeared on more than 20% of searches, and where one appears, click-through falls by close to 60%.

So ranking is worth far less than it used to be as a way of getting visits. That part is true and it is not coming back.

Here is the part that gets left out. Assistants do not answer from memory. They search, read what they find, and summarise it. If your page does not rank, it is not in the set of pages the assistant reads, so it cannot be quoted, cited or recommended. Ranking stopped being the destination and became the entry ticket.

Which means SEO is not one of three parallel options. It sits underneath the other two. An agency proposing GEO for a site with no search visibility at all is proposing to decorate a house with no foundation.

What AEO actually asks you to do

Answer engine optimisation is mostly work on your own pages, and it is unglamorous. The goal is to make a clean, liftable answer easy to find inside your content.

• Answer in the opening. Around 44% of citations come from the first 30% of a page. Lead with the conclusion, then justify it. Never build up to your point.
• Write headings as questions. They match the shape of the query being asked.
• Keep the direct answer short. Two or three sentences, immediately under the question, before any elaboration.
• Use a strict heading order. One H1, then H2, then H3, never skipping a level. About 69% of pages cited by ChatGPT follow proper hierarchy.
• Add FAQ markup, but only for questions visible on the page. Marking up questions a reader cannot see is the fastest way to get the markup ignored.

None of this is new thinking. It is the same discipline that won featured snippets five years ago, pointed at a bigger target.

What GEO adds on top

Generative engine optimisation is where something genuinely changed, and the research is more specific than the marketing suggests. A study from Princeton, Georgia Tech and IIT Delhi tested what actually moves the needle on being cited by a generative engine.

• Citing outside sources lifted visibility by 115%. A page that links to real evidence is treated as more quotable than one that asserts.
• Adding real statistics lifted it by 41%. Adding more words did nothing. The signal is factual density, not length.
• Freshness compounds. Pages updated in the last 30 days receive about 3.2 times more citations. For ChatGPT specifically, 76% of the most cited pages had been updated within the month.
• Comparisons win. Comparison articles account for 32.5% of all AI citations, the largest share of any format. Opinion pieces are a distant second at around 10%.

And then the finding that reframes the whole exercise: roughly 82% of AI citations come from earned media, and only about 6% from a brand's own owned or paid content.

You cannot publish your way into an AI answer. What the rest of the web says about you matters more than what you say about yourself.

That is why GEO done properly looks less like content marketing and more like public relations with a technical layer. Directory listings, review platforms, being included in someone else's "best of" article, being quoted, publishing data other people cite.

So are AEO and GEO the same thing?

Mostly, yes, and the industry knows it. There is an active argument among practitioners that the two terms describe one practice and that we should settle on a single name for it. The counter-argument is that generated answers behave differently enough from extracted snippets to deserve their own label.

Our position, for what it is worth: the useful split is not AEO against GEO. It is on-page against off-page. Structuring your own content is one kind of work. Getting the rest of the internet to describe you accurately is a different kind of work, with a different budget and a much longer timeline. Whatever you call them, those are the two things that need doing.

Practical consequence: if a proposal lands on your desk with three line items for SEO, AEO and GEO and three separate fees, ask what is actually different between them. A good answer exists. Most of the time you will not get one.

What to do, in order

For a small or mid-sized brand starting from nothing, the sequence matters more than the effort.

1. Fix what the web already says about you. Same business name, address, category and description across your website, Google Business Profile, directories and social profiles. This is cheap, boring, and the single most skipped step. Assistants assemble a description of a business from what the web consistently repeats.
2. Rewrite your five most important pages to answer their question in the opening paragraph. Not a rebuild. A rewrite of the top third.
3. Put numbers and sources into everything you publish. One figure with a link beats three paragraphs of confident adjectives.
4. Turn your strongest pages into honest comparisons where a comparison genuinely exists. This is the highest citation format by a wide margin.
5. Update before you publish more. Refreshing an existing article that already ranks usually returns more than adding a new one nobody finds.
6. Earn mentions. Listings, directories, industry roundups, quotes, original data. This is slow, and it is where 82% of the citations live.

How to tell whether any of it is working

Traffic is now a poor measure, because the successful outcome is often that someone reads about you and never visits. Track these instead.

• Does the assistant name you? Once a month, ask ChatGPT, Gemini and Perplexity the five questions a real buyer would ask before choosing someone like you. Write down whether you appear.
• Is what it says correct? Being described wrongly is worse than being absent, and it is fixable.
• Branded search volume. When people hear about you inside an answer, they search your name. That shows up in Search Console.
• What the AI traffic does. Visitors arriving from ChatGPT have been measured converting at around 15.9%, against roughly 1.76% from organic search. Small numbers, serious intent. Judge that traffic on what it does, not how much of it there is.

Common questions

Is SEO dead in 2026?

No, but its job changed. With 68% of searches ending without a click, ranking is worth much less as a way to win visits. It is worth more as a way to be eligible, because a page that does not rank is usually not in the set an assistant reads before answering.

Are AEO and GEO the same thing?

Close to it. Both are about being used as the answer rather than as a link. The distinction worth keeping is on-page work versus off-page work, not the two acronyms.

Do I need a separate agency for GEO?

Usually not. The work is content structure, factual accuracy, structured data, consistent business information and earned mentions. That is one job. Be careful with anyone charging three fees for it.

How long before a brand shows up in AI answers?

The on-page part can show results within weeks, because assistants re-read pages often and reward recency. The off-page part, which is the part that matters most, takes months, because it depends on other people publishing about you.

Where these figures came from

Zero-click and AI Overview figures are from SparkToro's analysis of Similarweb panel data covering United States Google searches from January to April 2026, reported by Search Engine Land. Citation format, freshness, earned media and conversion figures are collected in Omnibound's 2026 generative engine optimisation statistics. The visibility lifts from statistics and external citations come from the Princeton, Georgia Tech and IIT Delhi GEO study.

Two honest caveats, since this article argues for citing sources. Most of this measurement is published by companies that sell AI search services, and we sell this work too. And the click and search data is United States data. Indian search behaviour is not identical, and nobody has published anything as rigorous for this market yet. Treat the direction as reliable and the decimal places as decoration.
