I get asked this most weeks now, usually by someone who has just been pitched a GEO retainer at twice the price of their SEO one.
So let me be blunt, because this is one of those questions where the honest answer is commercially inconvenient for a lot of agencies.
GEO and AEO are not new disciplines. They are emphases within SEO, describing which surface you are optimising for. The underlying work is largely the same work, and nothing about them replaces the fundamentals.
That does not make the terms useless. They point at real differences in how these systems choose sources, and those differences change your priorities.
Here is what each one means and what genuinely differs between them.
Quick Info
The Definitions
SEO: Search Engine Optimisation
Making a site findable, understandable and preferable to search engines, so it earns visibility in results. Covers technical health, content, authority and user experience. Has existed for a quarter of a century and has absorbed every change so far.
AEO: Answer Engine Optimisation
Optimising to be the source of a direct answer rather than a link in a list. Concerned with featured snippets, voice results and AI answer boxes. Its methods are answer-first structure, clean question headings and question-answer markup.
GEO: Generative Engine Optimisation
Optimising to be cited by generative systems that synthesise answers from multiple sources. The term comes from academic research that tested which content changes actually improved visibility in generative search, and the findings are the useful part.
In practice AEO and GEO overlap so heavily that the distinction rarely changes what you do. I use GEO when I mean the specific research-backed tactics and largely ignore AEO as a separate label.
What Genuinely Differs
Three real differences, and they are worth knowing.
Notice that none of those three require a new discipline. They require different priorities inside the same discipline.
What Is Identical
This is the part the acronym sellers tend to skip.
Which is to say the overwhelming majority of the work is the same work.
Do You Need All Three?
You need one strategy that serves all three surfaces, which is not the same as three strategies.
Concretely, here is the whole difference between an SEO plan from three years ago and mine today.
That is seven changes. It is not a second retainer.
How to Read a GEO Proposal
If you are being pitched a separate service, a few questions sort the substantive offers from the repackaged ones.
Ask what they will do that differs from standard SEO. If the answer is a list of the seven items above, that is fine, but it belongs in the SEO scope you are already paying for.
Ask how they will measure it. Impressions from AI surfaces in Search Console and manual citation tracking are honest answers. A proprietary AI visibility score with no stated method is not.
Ask what happens to your technical SEO and your commercial pages under this plan. If the answer is nothing, you are buying content restructuring and should pay content restructuring prices.
A new acronym is not a new deliverable.
The One Thing Worth Emphasising
If I had to pick the single highest-leverage change out of everything in this article, it would be the passage test, and it costs nothing.
Take your most important page. Delete everything except one heading and the paragraph beneath it. Does what remains answer something useful, completely, on its own?
If yes, that page is doing GEO, AEO and SEO simultaneously and you did not need to buy anything.
If no, that is your next hour of work, and it will do more for you than any of the three acronyms as a purchase.
Frequently Asked Questions
No. Generative surfaces draw on the same crawled, indexed, trusted pool that search always has. GEO describes an emphasis within SEO, not a successor to it.
Almost certainly not. If your current SEO provider understands passage-level structure, entity markup and citation measurement, they are already equipped.
Answer-first headings, self-contained passages, named sources with specific numbers, real author entities, and a refresh schedule. Roughly seven items, all inside normal content work.
Whichever they already use. Arguing about the label wastes goodwill you could spend on the work.
Barely. AEO grew out of featured snippet and voice optimisation, GEO out of research on generative systems. The tactics converge on the same answer-first structure.
Repeating keywords for their own sake, withholding the answer to force scroll depth, and publishing thin pages to chase volume. All three now cost you on every surface.
Before You Go
The reason I am relaxed about this shift is that it rewards the same things good writing always rewarded. Answer the question, cite your source, say who you are.
The acronyms will keep multiplying. That part is not your problem.
