AEO vs. GEO vs. SEO in Plain English

Somebody has probably already tried to sell you GEO.

Before you buy it, it is worth being able to define it, because the fastest way to overpay for marketing is to purchase a term you cannot explain to your spouse.

Three acronyms are in circulation. Here they are without the sales layer.

SEO: search engine optimization

Getting your pages to rank in a list of links. The original discipline, roughly twenty five years old.

The work: relevant pages, sensible site structure, fast loading, other sites linking to you. The outcome you are buying is a position in a list, and the user clicks through to your site.

SEO is not dead, despite an article announcing its death every eighteen months. It is now one of several places you can be found rather than the only one.

AEO: answer engine optimization

Getting your business named in a direct answer instead of a list.

An answer engine is anything that responds with a conclusion rather than options. Google's AI summaries, ChatGPT, Perplexity, Claude, a voice assistant.

The difference that matters: a list has room for ten, an answer has room for about three. There is no page two, and often no click at all, because the customer got what they needed from the answer itself.

The work is different in kind, not just degree. Ranking is competitive. Being named is closer to being verifiable.

GEO: generative engine optimization

Practically the same thing as AEO. The term is newer and emphasizes generative systems that write an original answer rather than retrieve a stored one.

The distinction is real to academics and almost meaningless to a local business owner. If a vendor sells you AEO and GEO as two separate line items, ask what is different about the deliverables. Frequently the honest answer is "nothing."

Treat AEO and GEO as one discipline with two names. You are not missing a service.

What is actually different about the new work

The old question was "how do I outrank the other twelve results?" The new one is "why would a system be confident enough to say my name?"

Confidence comes from being easy to verify: information a machine can read, facts specific enough to repeat, details that agree with each other everywhere they appear, and other independent sources backing you up. That is the whole substance of AEO and GEO, and we walked through it in order here: how to get ChatGPT to recommend your business.

The useful reframe: SEO is a competition, AEO is a background check.

How much overlap is there

More than the acronym sellers imply. Perhaps seventy percent of the work serves both.

A fast, well structured site with clear pages about real services helps you rank and helps you get quoted. Accurate business information helps both. Being mentioned by other credible sites helps both.

What is genuinely new sits at the edges: writing that is specific enough to be quoted verbatim, structured data that states your facts in machine terms, and consistency across platforms mattering far more than it used to, because a contradiction now produces uncertainty rather than a slightly lower ranking.

So the honest answer to "should I stop doing SEO and start doing GEO" is no. You should do the seventy percent that was always the work, then add the edges.

Which one your business should care about

Depends on one thing: how your customers ask.

If they type a few words into Google and scan the results, SEO is still where your attention belongs, and the map results matter more than the blue links.

If they are increasingly asking an assistant a full sentence and taking the recommendation, you need to be verifiable, whatever the acronym.

You do not have to guess which is happening. Ask ten recent customers how they found you, and ask an AI about your own business and see what it says: run the three prompts.

The buyer's test

Any vendor selling you any of the three acronyms should be able to answer these without flinching.

• What specifically will you change on my site, and can I see it?
• How will we know in ninety days whether it worked?
• What are you not able to control?

A vendor who cannot name what they do not control is guessing or selling. In this field the honest answer to the third question is long, and hearing it is a good sign.
