AEO, GEO, SEO: what is actually different?
The short answer
SEO gets your pages ranked in a list of links on Google. AEO gets one of your pages picked as the direct answer to a question. GEO gets your brand named inside the answers that ChatGPT, Perplexity, Gemini and Google AI write. Same foundations, three different finish lines.

One definition each
Three jobs, in plain words.
SEO, search engine optimization
The twenty-year-old craft of getting your pages ranked when someone types a query into Google or Bing. You win positions in a list of links, and the visitor clicks through to your site. Success is measured in rankings, clicks and traffic.
AEO, answer engine optimization
Being the single direct answer instead of one link among ten: the featured snippet at the top of Google, the voice assistant's reply, the paragraph an AI lifts word for word. The craft is writing one clean, self-contained answer block per question.
GEO, generative engine optimization
Being named when an AI writes its answer. When a buyer asks ChatGPT "who should I hire for X", the engine assembles a reply from your site AND from what the rest of the web says about you: review sites, ranked lists, communities, media. GEO is the work of showing up in that assembled answer, measured by how often you are named against your competitors.
Side by side
The differences that change what you do on Monday.
| SEO | AEO | GEO | |
|---|---|---|---|
| What it optimizes for | Ranking your pages in a list of links | Being THE direct answer to a question | Being named inside AI-generated answers |
| Where it shows up | Google and Bing result pages | Featured snippets, People Also Ask, voice assistants | ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews |
| The success metric | Positions, clicks, organic traffic | Answer box ownership, zero-click visibility | How often the AI names you, against competitors |
| What the machine reads | Your pages, your links, your site health | One extractable answer block on your page | Your pages PLUS what the whole web says about you: reviews, lists, communities, media |
| The main levers | Content, technical health, links | Question-shaped headings, direct answer blocks | Citable pages, sourced numbers, off-site mentions, entity consistency |
| Time to results | Months | Weeks to months | First citations in 2 to 6 weeks, compounding over 3 to 6 months |
| What can kill it silently | A penalty, a migration gone wrong | A competitor writing a cleaner answer | A blocked AI crawler, or answers rebuilt from sources you are absent from |
For a marketing team
What actually changes in the work.
You stop optimizing pages and start optimizing passages
Generative engines lift paragraphs, tables and definitions, not whole pages. Every block has to make sense quoted alone, with the point stated first and a number in it. A page that builds up to its conclusion never gets quoted.
Half the work moves off your website
The engines assemble answers from review platforms, ranked lists, Reddit, LinkedIn and media. Being absent from those sources means being absent from the answer, whatever your own site says. Placements become part of the monthly work, not a PR luxury.
Measurement changes shape
Rankings and clicks do not tell you whether an AI names you. The new measurement is asking the engines your buyers’ questions, on a schedule, several times each because answers change between runs, and counting who gets named. We publish our own measurement every week, and the method behind it at /methodology.
Questions
Fair questions about the three. Straight answers.
Does GEO replace SEO?
No. AI search features run on the same ranking and quality systems as normal search: Google says so in its own guidance, and the retrieval engines lean on Google and Bing indexes. A page that cannot rank cannot be retrieved. GEO extends SEO with one new question: once the machine can find you, does it quote you?
Is AEO just a new name for featured snippets?
Mostly, yes. AEO existed before AI chat: it is the craft of being the single direct answer (snippets, voice search). GEO absorbed most of it, because the same answer blocks that won snippets are what generative engines lift. In 2026 the two words are often used interchangeably; the work overlaps almost entirely.
Which one should a B2B company do first?
If your site has technical SEO problems, fix those first: they block everything else. If your SEO is healthy, GEO is where the open ground is: most categories still have no settled owner in AI answers, while page one of Google has been fought over for twenty years. The cheapest way to decide is to measure where you stand today.
My SEO agency says GEO is included in my retainer. Is it?
Ask what lands every month, in writing. Below $3,000 a month, most of this market sells monitoring: a dashboard, a report, recommendations. Real GEO work produces things: new answer pages, refreshed pages, placements on the sites the engines read. If the list of produced things is empty, it is a report, not a program.
Do keywords still matter?
Less than intent does. Generative engines understand synonyms and phrasing, so covering twenty variants of one keyword is wasted work. What matters is answering the real question completely, on a page the engines can read, with facts they can quote.
