What is Citation Capsule?

The Citation Capsule concept was developed as AI search engines began selecting specific passages from web pages to include in their generated answers. Research shows that AI systems like ChatGPT and Google AI Overviews prefer passages that are 134-167 words, start with a direct answer, contain at least one specific statistic with source attribution, and can stand alone without requiring the rest of the article for context. To create an effective Citation Capsule: start with the most important fact or answer in the first 40-60 words, include 1-2 named data points, ensure the passage answers a specific question completely, and avoid referencing other sections of the article. Pages with well-structured Citation Capsules see up to 340% higher AI citation rates compared to standard paragraph formatting. This technique works across all AI platforms because it aligns with how large language models select and present information.
