SEO gets your page ranked in the list of search results. Answer engine optimization (AEO) gets a passage from your page shown as the direct answer to a question. Generative engine optimization (GEO) gets your brand named and cited when an AI engine writes an answer of its own. They are three layers of the same job, and one site can do all of them.

| What you work on | Relevance, technical health, links | Questions, answer-first writing, structured data | Entity clarity, authority, coverage across the web |

What is SEO?
Search engine optimization (SEO) is the work of improving a website so it appears higher in the organic, unpaid results of a search engine. It covers keyword research, content, technical fixes, and link building. The unit of success is a page ranking for a query, and the payoff is a click through to your site.
What is AEO?
Answer engine optimization (AEO) is the practice of structuring your content so it can be extracted as the direct answer to a question, in a featured snippet, a voice assistant, or an AI chatbot, rather than buried inside a page.
An answer engine is not looking for ten options. It wants one passage it can show or read out. AEO is the craft of writing that passage: a heading that asks the question the way people ask it, the answer in the first sentence or two, the supporting detail after it, and structured data that says what each part of the page is.
What is GEO?
Generative engine optimization (GEO) is the practice of optimizing your brand and content so they are surfaced and cited by AI-powered search and answer engines, such as Google's AI Overviews, ChatGPT, Perplexity, and Gemini, and not only ranked in the traditional list of links.
A generative engine composes its answer from many sources and decides which brands to mention along the way. GEO works at that level. It makes it unambiguous who you are and what you do, earns the third-party mentions and reviews that a model treats as evidence, and covers your subject completely enough that you are a source worth citing.
What the three share
All three rest on one foundation. An engine has to be able to crawl a page, understand it, and trust the site it sits on before it will rank the page, quote it, or cite it. So the unglamorous SEO work carries straight over:
- A site that is fast, crawlable, and free of technical errors.
- Content that gives the searcher what they came for.
- Structured data that says what each page and each entity is.
- Authority: links and mentions from sites the engines already trust.
This is why AEO and GEO extend SEO and do not replace it. A page that an engine does not trust enough to rank is unlikely to be the one it quotes.
Where they differ
The unit. SEO ranks a page. AEO lifts a passage. GEO cites a brand.
The format. A long, thorough page can rank well. An answer needs a tight passage that makes sense on its own. A citation needs the facts about you to agree everywhere they appear: your site, your profiles, your reviews, and what the press has written.
The click. SEO succeeds when someone visits. AEO and GEO often succeed without a visit, because the searcher reads the answer and stops there. The value is in being the name they saw, so you measure presence as well as traffic.
Which one do you need?
Most businesses need all three, in this order.
- Start with SEO. If the site has technical problems, thin content, or little authority, fix that first. Nothing built on top of it will hold.
- Add AEO to the pages that answer questions. Definitions, how-tos, comparisons, pricing, and eligibility pages are the candidates. It is usually the quickest of the three to act on, because most of the work is restructuring pages you already have.
- Invest in GEO when your buyers ask AI tools for recommendations in your category. That work is slower, because it depends on what the rest of the web says about you.
Common questions
Is AEO replacing SEO?
No. AEO depends on SEO. The engines that show direct answers draw them from pages they already crawl, rank, and trust.
Is GEO the same as AEO?
They overlap, and many people use the two terms for the same thing. The useful distinction is scale. AEO works question by question, shaping a page so one answer can be lifted out of it. GEO works at the level of the brand, building the signals that lead an AI engine to name you when it writes a longer answer.
Do I need separate content for each?
Rarely. One well-built page can rank, supply a quoted answer, and be cited. What changes is how the page is organized: a heading phrased as the question, the answer up front, facts that stay true out of context, and markup that tells a machine what it is reading.
How PressRoom approaches it
We plan the three as one program, because they share a foundation and compete for the same hours: SEO services for the foundation, answer engine optimization for the pages that answer your buyers' questions, and generative engine optimization for how AI engines describe your brand.
