Search now offers three ways to find answers: search engine optimization (SEO), answer engine optimization (AEO), and generative engine optimization (GEO). SEO targets the list of links. AEO targets the answer box above them. GEO targets AI chat tools that write their own reply.
SEO aims at the traditional results page
SEO is the practice of helping a page rank higher in the list of links people see after a search. It relies on things like relevant keywords, clear headings, fast loading times, and other websites linking back to your page. Search engines still read a page this way, even when other features sit on the same results page.
SEO has been around the longest, and it still matters. Plenty of people scroll through a list of links and click the one that looks most useful. That habit hasn't gone away, even as new features crowd the top of the page.
AEO aims at the answer box
AEO targets the box that often appears above the list of links. Google calls this a featured snippet. According to Google Search Central's guide to featured snippets and your website, these boxes reverse the usual format of a search result, showing "the descriptive snippet first." They can also show up inside the related questions group known as "People Also Ask."
Winning this spot means stating the answer in plain words at the start of a section, then adding detail after. Search engines pull that short answer straight into the box, so the order of a section matters as much as its content.
GEO aims at AI chat tools that write their own reply
GEO is the newest of the three terms. It covers tools such as ChatGPT, Gemini, and Perplexity, which read many pages and write a fresh answer in their own words. Sometimes these tools name a source, and sometimes they don't.
Researchers Pranjal Aggarwal and co-authors coined this term in a paper called "GEO: Generative Engine Optimization", built to help "content creators in improving their content visibility in generative engine responses." Their tests found that this approach "can boost visibility by up to 40% in generative engine responses."
These tools favor pages that state facts clearly, use plain words, and group information under headings that match real questions. Pages written for people, rather than written to game a ranking formula, tend to do better here.
The three overlap more than they compete
You don't need three separate pages, or three separate strategies, to win all three doors. A page that answers a real question clearly, uses a plain heading for each subtopic, and backs up claims with facts tends to work for SEO, AEO and GEO at once.
Google's own guidance backs this up. Per Google Search Central's guide to AI features and your website, its AI Overviews and AI Mode features "surface relevant links to help people find information quickly and reliably," and "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." Pages only need to be indexed and eligible to show in Google Search with a snippet, fulfilling the standard search technical requirements.
Rankings on the traditional results page reward relevance and structure. The answer box rewards a short, direct answer near the top of a section. AI chat tools reward clear, organized facts they can pull from with confidence. These goals line up more often than they conflict, so a business rarely has to pick a single target.
What a page needs to work for all three
A page designed to cover all three doors usually includes:
- A plain-language answer near the top of the page and near the top of each section
- Headings that match the way people ask questions
- Short paragraphs that state one idea at a time
- Facts and examples that are easy to quote out of context
- Consistent details about your business across your website and other listings
The short answer
SEO, AEO and GEO are three ways people now find information online: the traditional results page, the answer box above it, and AI chat tools that write their own reply. Each one rewards a slightly different approach, but a page that states clear answers early, uses plain language, and organizes information under useful headings tends to perform well across all three doors at once. Small businesses don't need a separate plan for each; one clear, well-organized page can carry the weight for all three.
Frequently asked questions
Is AEO the same as SEO? No. SEO targets the list of links on a results page, while AEO targets the answer box that appears above it, sometimes called a featured snippet.
Do I need separate pages for SEO, AEO and GEO? No. One page that states a clear answer early, uses plain language, and organizes facts under useful headings can work for all three doors at once.
Does Google require special work to appear in AI Overviews? No. Per Google Search Central, a page needs only to be indexed and eligible to show in Google Search with a snippet, the same bar as regular search results.
