How to get cited, summarised, and reused by AI tools like ChatGPT, Gemini, Claude, and Perplexity.
GEO (Generative Engine Optimization) is the practice of structuring your content so it becomes a cited or synthesised source in AI-generated responses.

| Factor | Description |
|---|---|
| Semantic relevance | Does your content match the meaning behind a prompt? |
| Source trust | Are you quoted, cited, and linked to elsewhere? |
| Content structure | Is your writing easy to summarize or extract from? |
| Entity recognition | Do you use known entities and consistent phrasing? |
| Fluency and flow | Can your paragraph be copied or reused directly in answers? |
| Citation signal | Do you include statistics, author names, quotes, or references? |
