Is GEO replacing SEO?
No. The pages that rank in search are often the pages generative engines read, so most GEO work is also SEO work. The difference is in the goal and the measurement: a ranking position versus being named in an answer.

GEO vs AEO
Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) both name the practice of making a brand more likely to be used and named when an engine writes an answer instead of listing links. GEO is the newer term and refers to engines that generate text with a language model. AEO is older and refers to any engine that answers a question directly, which once meant featured snippets and voice assistants and now includes the same generative engines.
Generative Engine Optimization
GEO describes the work of shaping content, structure and outside references so that a generative engine such as ChatGPT, Gemini, Perplexity or Google AI Overviews draws on a brand's material and names it in the answer. The term was used in a 2023 research paper by Aggarwal and colleagues titled "GEO: Generative Engine Optimization", and many practitioners adopted it from there.
Answer Engine Optimization
AEO describes the same goal for engines that answer directly: being the answer rather than one of the results. It predates generative AI, when the targets were featured snippets, knowledge panels and voice assistants. G2 named its software category AEO, so vendors listed there describe themselves in those words even when their own marketing says GEO.
Where they overlap and where they differ
In practice the two terms cover the same tasks: answering buyer questions plainly on the brand's own pages, being described consistently on third-party sites the engines read, and publishing the facts an engine needs to name the brand with confidence. The field has not settled on one word. The difference is mostly who is speaking: G2 and some vendors say AEO, many practitioners and researchers say GEO.
What both terms share is that they describe the practice, not the result. "AI visibility" names the measurement: how often the brand is actually named when buyers ask. GEO or AEO is what a team does; AI visibility is what it measures before and after.
FAQ
Which term should I use?
Use the one your audience uses. On this site we say GEO for the practice and AI visibility for the measurement, and we avoid both when a plainer phrase works, such as "getting named in AI answers".
