## What it is

Generative engine optimization is the practice of changing web content to increase how often and how prominently a source is cited in an answer generated by an AI search system. The term comes from a paper by Aggarwal and colleagues, first posted in November 2023 and published at KDD 2024, which formalised the generative engine — a system that gathers and summarises sources to answer a query — and proposed GEO as a way for content creators to “increase their visibility (or impression) in generative engine responses”. Its headline gain of up to 40% was measured on two impression metrics the authors defined, Position-Adjusted Word Count and Subjective Impression, not on citation rates. The experiment handed the engine a fixed set of sources, so what improved was the prominence of a source already in front of the model, not the chance of being retrieved at all.

## Why it matters

The tactics are young and contested, which is why this entry is flagged for review rather than treated as established practice. C-SEO Bench, published at NeurIPS 2025, retested the same stylistic rewrites across more domains and with several sites competing at once, and found most of them “not only largely ineffective but also frequently have a negative impact on document ranking”, with conventional retrieval-focused SEO doing considerably better. The underlying shift is not in dispute: visibility is increasingly a question of being cited rather than being ranked, and a citation is only worth having if the sentence being cited is accurate. Knowledge Company sells the accuracy rather than the visibility for that reason. Optimising to be quoted more often while your claims go unmaintained simply distributes the error faster.
