Three acronyms now dominate conversations about search: SEO, AEO and GEO. They are often used interchangeably, which makes planning harder than it should be. They describe different targets, and understanding the difference tells you where to spend limited time.
SEO: ranking pages in search results
Search engine optimisation is the established discipline. The goal is for your pages to rank well in a search engine for the queries your customers use. The work covers technical health, relevant content, internal linking and earning links from other sites. The reward is a position in a list and the clicks that come from it.
AEO: being the direct answer
Answer engine optimisation targets places where a search system gives a direct answer instead of a list, such as featured snippets, voice answers and the summary boxes above results. The central idea is to state a clear, concise answer to a specific question, then support it with detail. Formatting matters here. Short definitions, step lists and tables are easier for a system to lift than long narrative paragraphs.
GEO: being included in generated answers
Generative engine optimisation targets assistants and AI search features that write an answer by combining several sources. The aim is for your brand or page to be included in that composed answer and, where the product shows sources, to be cited. The levers are clarity of identity, quality and specificity of content, the consistency of how the web describes you, and whether the relevant crawlers can read your pages.
How they overlap
In practice the three share most of their foundations. A page that loads fast, is indexable, answers a question directly, and sits on a site with a clear identity helps in all three. The differences are in emphasis:
- SEO emphasises relevance and authority for ranking.
- AEO emphasises concise, extractable answers.
- GEO emphasises being understood and trusted as an entity across many sources.
A site that does the basics well is already partway to all three.
How to split your effort
If your technical foundations are weak, fix those first, because every discipline depends on them. If foundations are sound, add answer-first formatting to your most important pages and make sure your organisation, people and services are described clearly. Then measure whether assistants are naming you.
The Search Readiness Auditor checks the shared foundations, including indexability, structure, schema and AI crawler access, so you can see which of the three needs attention. To see the result in generated answers, use the AI visibility approach described in our introduction.
A side-by-side view
| Discipline | Main target |
|---|---|
| SEO | Ranked pages in a list of results, and the clicks from them |
| AEO | Direct answers such as featured snippets and voice responses |
| GEO | Inclusion and citation inside answers written by AI systems |
The table is a simplification, but it captures the practical difference. The first two are about how a page is presented in a search product. The third is about how a brand is understood and represented across many sources at once.
What SEO work still carries over
Plenty of established SEO practice supports the newer disciplines directly. Fast, mobile-friendly pages are easier for any crawler to handle. Clean internal linking helps systems understand which pages matter. Original, expert content earns links and mentions, which also shape how assistants describe you. Technical hygiene, such as correct canonical tags and a working sitemap, prevents confusion about which version of a page is authoritative.
If you already invest in these, you are not starting from zero for AI search. The extra work is mostly in measurement and in a few specific habits around clarity and structure.
The extra habits that GEO adds
- Entity clarity. Make sure your organisation, people and services are defined consistently, with structured data that backs it up.
- Quotable passages. Write short, self-contained answers that make sense when lifted out of the page.
- Off-site consistency. Keep your profile information aligned across directories, social platforms and professional listings.
- Crawler access. Check that the crawlers behind the assistants you care about can reach your pages.
- Answer-level measurement. Track whether you are named in generated answers, not only where you rank.
A practical weekly rhythm
You do not need a large team. A modest weekly routine works. Spend one session on technical checks and fixes. Spend another publishing or improving one page that answers a real customer question. Spend a short session reviewing mentions and listings. Once a month, rerun your fixed question set and record what changed. Over a quarter that routine compounds into a visible improvement, and it keeps all three disciplines moving together instead of treating them as rival projects.
What not to do
Avoid treating GEO as a trick. There is no hidden setting that makes assistants recommend you. Pages written to manipulate a system tend to age badly, while pages written to help a reader tend to keep working as systems change. Also avoid abandoning SEO. Many AI products draw on traditional search indexes, so strong search performance often supports AI visibility rather than competing with it.
Frequently asked questions
Is GEO replacing SEO?
No. They overlap heavily, and many AI features rely on search indexes. GEO adds measurement and tactics for generated answers on top of solid SEO.
Is AEO still relevant?
Yes. Direct-answer formats still appear in search, and the habit of writing short, clear answers helps generative systems as well.
Which one should a small business start with?
Start with the shared foundations: a fast indexable site, clear pages and consistent business information. Then add answer-first content and structured data.
Do I need three separate strategies?
Usually one plan is enough. Build good foundations, write answer-first pages, describe your entity clearly, and measure in both search and AI answers.
