AEO vs GEO

GEO and AEO are two names for closely related work, and they are often used as if they were one. Joe Ashta writes his role as GEO / AEO consultant for law firms and uses both terms on purpose. This page gives each term's origin, what each optimizes for, how they overlap, why this site keeps both, and when to say which.

GEO: the broader, academic term

Generative Engine Optimization is the older and wider of the two. It entered use through a 2023 research paper by researchers at Princeton, Georgia Tech, the Allen Institute for AI and IIT Delhi, who studied how content could be made more visible in the answers generative systems produce. The paper named the field and framed the problem as visibility inside a generated response, as distinct from position in a ranked list. Research, and the parts of the industry closest to research, have used GEO since.

GEO covers the whole generative process. For a law firm that means every stage from a page being retrieved, to that page being used as grounding, to a link to it appearing as a citation, to the firm being named in the answer, to the firm being named as one to hire.

AEO: the narrower, practitioner term

Answer Engine Optimization grew up among practitioners who needed a word for the outcome a client pays for. AEO concentrates on the last stages of the same process: the firm named in the answer, which the glossary calls a mention, and the firm named as something to hire, a recommendation. It is the brand visibility and revenue layer. A firm asking "are we in the answer, and are we the answer" is asking an AEO question.

Side by side

They are correlated

The two terms describe one process from different distances, so results in one move with results in the other. A firm that improves its grounding presence, a GEO outcome, gets more chances to be named, an AEO outcome. A firm that is named more often is, almost always, being retrieved and cited more often. The correlation is close and it is expected. It is also imperfect. A firm can be cited as background on a general question about family law without being named as a firm to hire, so its GEO numbers rise while its AEO numbers stay flat. The glossary entry on vendor-reported vs. measured numbers describes that gap from the measurement side.

Why this site writes "GEO / AEO consultant"

Three reasons. The first is accuracy: the work spans the whole process, which is GEO, and it is judged by the answer, which is AEO, so one term alone would either overstate the scope or understate it. The second is the reader. A managing partner who has read a trade article knows AEO; a marketing director who has read the research knows GEO; a search for either term should reach the same person. The third is consistency. The role is stated in one form everywhere Joe Ashta is described, in the entity record and on every page of this site, and that one form carries both words. Generative Engine Optimization and Answer Engine Optimization each take one term at length.

When to say which

• Say GEO when the subject is the process: retrieval, grounding, which pages a system reads, why a citation appeared, how a platform builds an answer. Say it when writing for researchers or for people who work on the platforms.
• Say AEO when the subject is the outcome: whether the firm was named, whether it was recommended, what the mention rate is, what the client is paying for. Say it in proposals, reports and conversations with the firm.
• Say GEO / AEO when naming the discipline or the role, so that both audiences recognize it.

Either way, the work for a law firm is the same: one clear entity, structured data that states it, pages that answer the buyer's questions, and corroboration from sources the firm does not control.
