AEO is what your pages say. GEO is whether anyone else confirms it.
AEO is work on your own pages: making a claim structured, direct and unambiguous enough that a system can lift and attribute it. GEO is work on the evidence outside them: the corroboration a generative system needs before it will state a fact about a brand at all. That makes GEO the one search discipline you cannot finish on your own site.
The two are often sold as the same service. They act on opposite sides of the same boundary, and only one of them is inside your control.
Where they part
5 dimensionsWhere the work happens
AEO happens on the site: openings, headings, entities, structured data that matches what is visible. GEO happens off it, in whatever already describes the business — and its output is usually a list of claims that nothing outside the site confirms.
What the system needs
An answer engine needs a statement it can extract and attribute. A generative system needs a reason to believe the statement before repeating it, which is why it will not assert something about a brand on the brand’s word alone.
The failure mode
AEO failing looks like a page nobody quotes. GEO failing looks like a brand described wrongly — or a different company’s answers put in front of your customers, because the name resolved to the entity a system understood better.
What you can do unilaterally
All of AEO. Very little of GEO: consistency is something you can control across your own descriptions, but corroboration is by definition somebody else’s statement, which is why GEO work is slower and cannot be scheduled like a content sprint.
Knowledge graphs
Neither discipline gets a brand into one by asserting it. Entry follows from consistent, externally corroborated facts, which makes tidying the places that already describe a business more productive than adding markup to your own pages.
Common questions
Answer first, then the reasoningAre GEO and AEO the same thing?
No. They are adjacent and they share a goal, but they act on different material: AEO on the statements your pages make, GEO on whether anything outside your pages confirms them. A site can be excellent at one and absent at the other.
Can GEO be done entirely on my own website?
No. Consistency across your own descriptions is necessary and is inside your control, but corroboration is somebody else’s statement about you. That is what makes GEO the one search discipline that cannot be completed on your own site.
Why would a technically perfect site still be described wrongly?
Because the ambiguity lives outside it. If a brand shares its name with a larger or older business, a system will answer questions about the one it understands better — and no amount of content on your own site resolves that.
