If you only read one box
SEO gets your page ranked. AEO makes your page the direct answer. GEO gets your content cited inside AI-generated answers. They are layers on the same pages, not competing strategies. You do not choose between them.
- SEO is the foundation. AI answers mostly draw from pages that are already crawled, indexed, and ranking.
- AEO is a writing habit. Lead with the answer, match the question, keep each passage self-contained.
- GEO is mostly off your own site. It comes from being talked about consistently across independent sources.
The three definitions, kept plain
SEO improves where a page ranks so a person clicks through to it. AEO structures that same page so it becomes the direct answer in a featured snippet, a People Also Ask box, or an AI answer. GEO is about getting cited and recommended inside AI-generated answers. One page, three different questions about how it performs.
The acronyms sound like rival philosophies. They are closer to three views of the same work, each asking a different question about the same page.
| Term | What it optimizes for | What success looks like |
|---|---|---|
| SEO Search engine optimization | Where a page ranks in a list of results, so a human sees it and clicks through. | Your page appears high enough on the results page that people actually reach your site. |
| AEO Answer engine optimization | Being the direct answer, in featured snippets, People Also Ask, and AI answer boxes. | Your wording is what gets lifted and shown as the answer, not just linked to. |
| GEO Generative engine optimization | Being cited and recommended inside an AI-generated answer written from many sources. | The assistant names you, or quotes you, when someone asks about your category. |
GEO is the newest of the three and the only one with an academic origin. It comes from a paper by researchers at Princeton and IIT-Delhi, "GEO: Generative Engine Optimization," presented at KDD 2024, which tested content changes against generative search engines and found that targeted edits could lift visibility in generated answers by up to 40% in their benchmark. That is a research result on a test set, not a promise about your business, and it is worth reading in that spirit.

Why you still need SEO to do either of the others
AI engines mostly draw from pages that are already crawled, indexed, and ranking. Google's own guidance says its AI features use core Search ranking systems, and that there is nothing special required beyond good SEO plus clarity. So SEO is not the thing AEO and GEO replaced. It is the thing both of them stand on.
This is the part the acronym sellers tend to skip. If a page cannot be found by an ordinary crawler, it is usually not available to be quoted by an answer engine either. Google has said plainly that its AI experiences run on core Search ranking systems, and that site owners do not need a separate set of tactics to appear in them. The fundamentals still gate everything downstream.

None of this means SEO is unchanged. What people click, and how often they click at all, is shifting as answers appear on the results page. But the plumbing underneath is the same plumbing, and a business that has not done the basic version of it has no route into an AI answer.
What actually changes in practice
The three layers ask for different, fairly unglamorous work. For SEO you care about being indexed, clear page titles, sensible internal links, and pages that load. For AEO you care about leading each section with the answer and matching the literal question. For GEO you care about being talked about consistently on sites you do not own.
Written out as a checklist, it stops feeling mysterious.
- SEO work: make sure the pages are indexed, give each one an honest and specific title, link between related pages so both people and crawlers can move around, and keep the site fast enough not to get in the way.
- AEO work: open every section with the answer in a sentence or two, use headings that match the question the way a customer would actually say it, and keep each passage self-contained so it makes sense when it is lifted out of context.
- GEO work: get mentioned in the places an engine already reads. Directories, review platforms, local roundups, industry lists, and community threads. Engines lean on third-party consensus about you far more than on markup you add to your own site.
Notice how little of the third bucket happens on your website. That is the uncomfortable part of GEO. You can control your own pages completely and still be invisible if nobody independent is describing you.
The honest note about FAQ schema
Google confirmed in 2026 that FAQ rich results no longer appear in search, and removed the search appearance and its reporting. FAQPage schema is still valid, and it still helps machines tell which text is a question and which is its answer, but it is no longer a visible Google feature. Anyone selling FAQ schema as a search feature is selling something that was retired.
This matters because FAQ markup has been sold hard for years as a way to take up more room on the results page. That version of the story is over. The markup itself is not harmful and still does useful quiet work: it labels a question and its answer unambiguously for anything reading the page. Keep it if it helps machines parse your content. Do not pay a premium for it as a visibility feature.

The wider point: structured data is useful, and it is also oversold. It helps machines read you accurately. It is not the lever most businesses are missing.
One study of 10,000 local businesses found that reviews and local presence correlated far more strongly with AI visibility than schema, llms.txt files, or page speed, which showed weak or no correlation. That study is vendor-sourced, so treat it as directional rather than settled, but it points the same way as everything else on this page. Being well described by other people beats being well marked up by you.

Which should a small business focus on first?
In order: be findable and readable, which is ordinary SEO. Then make the content answer-first, which is AEO. Then build third-party presence and reviews, which is GEO. Most small businesses do this backwards. They buy the third layer from someone before anyone, human or machine, can reliably find and read the first one.
The sequence is not glamorous, but it is the one that holds up:
- First, be findable and readable. Pages that are indexed, content that is in the HTML rather than loaded by a script, consistent business details, honest titles. This is the step that gets skipped.
- Second, answer the questions directly. Rewrite your key pages so each section opens with a plain answer to a real question. This costs nothing but attention.
- Third, work on how the web describes you. Listings, reviews with specific detail in them, and mentions on sites you do not own. This is slower and it is the part you cannot shortcut.
If you only ever do the first two, you will be in better shape than most businesses in your category. Nobody can promise you a ranking or a citation, and you should be wary of anyone who does. What you can control is whether there is something clear and quotable to find.
Frequently asked
What is the difference between SEO and AEO?
SEO is about where your page ranks, so a person sees the link and clicks through to your site. AEO is about how your page is written, so an engine can lift a clean, complete answer straight out of it. They apply to the same page. SEO gets the page found, and AEO makes the content on it easy to quote.
Is AEO replacing SEO?
No. AI answer features are built on top of existing search infrastructure, and Google's own guidance says its AI experiences use core Search ranking systems. A page that is not crawled, indexed, or ranking is usually not available to be quoted either. AEO is a layer of work you add to SEO, not a replacement for it.
What is GEO in marketing?
GEO stands for generative engine optimization. The term comes from a 2023 research paper by teams at Princeton and IIT-Delhi, and it means shaping content so it gets cited and recommended inside AI-generated answers rather than only ranked in a list of links. In practice it depends heavily on how consistently independent sources talk about you.
Do I need to do all three?
Most businesses do, but not at once and not equally. The order that works is fundamentals first, so you are indexed and readable, then answer-first content, then third-party presence and reviews. If your site cannot be crawled or your business details conflict across the web, the later layers rarely pay off.
Does FAQ schema still work?
It depends what you mean by work. Google confirmed in 2026 that FAQ rich results no longer appear in search, and it removed the search appearance and its reporting, so FAQ markup will not earn you a visible feature anymore. The schema is still valid and still helps machines identify which text is a question and which is its answer. Treat it as clarity for machines, not as a search feature.
Which layer is missing in your business?
Most businesses are not missing all three. They are missing one, and usually not the one they were about to pay for. The AI Search Audit looks at your pages, your listings, and how the web currently describes you, then tells you where the gap is.
