What is GEO (Generative Engine Optimization)?

GEO is an academic framework first posted to arXiv in November 2023 by a team including Princeton-affiliated researchers, later presented at KDD 2024. It tested nine techniques and found that several of them measurably raise the odds an AI search engine cites your content: adding expert citations raised citation likelihood by up to 41%, and adding statistics or clarifying sources each raised it by about 30%, while some tactics (like keyword stuffing) had no or negative effect — validated through the GEO-bench benchmark.

What is the difference between AEO and GEO?

GEO is the original academic term (Princeton-affiliated researchers, 2023); AEO is how the marketing and agency industry refers to the same practice. Some extend AEO to 'AI Agent Engine Optimization,' covering future autonomous AI agents beyond today's chatbots. In practice, the two terms are used interchangeably.

How does GEO/AEO differ from traditional SEO?

SEO targets search rankings and clicks; GEO/AEO targets citations and mentions inside AI-generated answers. This distinction matters because SparkToro's 2026 analysis found more than 68% of Google searches no longer send a click, as AI Overviews and similar summaries increasingly answer queries directly on the results page.

Are AEO, GEO, AIO, and LLMO the Same Thing?

AEO, GEO, and LLMO overlap in meaning and share the same underlying goal. GEO is the academic term coined first, AEO is what the marketing industry now calls it, and LLMO is a rarer scholarly variant. In practice, all three mean optimizing so AI search engines cite and mention your content.
