What is Generative Engine Optimization (GEO)?
GEO is the practice of getting cited — accurately and favorably — by generative AI engines like ChatGPT, Perplexity, and Gemini. It's the reputation layer for a world where users read AI answers instead of clicking search results.
GEO vs SEO
SEO optimizes for the ten blue links. GEO optimizes for the paragraph the AI writes above them. The mechanics rhyme — structured content, canonical sources, authoritative citations — but the target changes. In SEO you want a click. In GEO you want to be the answer.

How to measure GEO
The core GEO metric is citation authority — how consistently a person or brand shows up in AI answers, weighted by the credibility of the domains the AI cites. ImCited scores this 0–100 using three curated prompts (identity, category, framework attribution) run against Perplexity Sonar.
