## Definition

GEO (Generative Engine Optimization) is the practice of structuring content so that large language models — ChatGPT, Google Gemini, Perplexity, Claude — cite, quote, or recommend your brand inside their generated answers. Where SEO optimizes for a ten-blue-link ranking, GEO optimizes for being the source the model picks when it writes the answer.

The term was coined in a [November 2023 paper](https://arxiv.org/abs/2311.09735) by Aggarwal, Murahari and Rajpurohit (KDD 2024), which showed targeted optimizations could boost generative-engine visibility by up to 40%. It hit mainstream marketing vocabulary after a16z's May 2025 ["GEO over SEO"](https://a16z.com/geo-over-seo/) essay, and by early 2026 is a fixture across Semrush, HubSpot, Jasper, and Conductor playbooks.

## Example

Semrush's AI Visibility Index tracks 2,500 prompts across ChatGPT, Gemini, Perplexity and Google AI Overviews to show which brands get cited. A GEO-optimized page structures self-contained paragraphs, schema markup and explicit entity statements so the model can extract a sentence verbatim — the same move that earns a featured snippet, applied to generative answers.

## Analogy

SEO is getting your book on the library shelf; GEO is getting the librarian to quote you when someone asks a question.

## Why it's emerging now

AI Overviews dropped click-through on top Google results by about 58%, so every brand suddenly needs a strategy for showing up inside AI answers, not just above them. a16z's May 2025 essay legitimized GEO as a board-deck category and 2025-2026 saw a wave of GEO-branded tooling (Profound, Semrush AI Visibility, HubSpot AEO, Jasper, Argeo).
