Answer Capsule
An Answer Capsule is a 40–60 word direct-answer block placed within the first 200 words of an article, structured as 'definition + key action'. It is the highest-ROI GEO writing pattern because ChatGPT, Perplexity, and Google AI Overviews preferentially extract self-contained, copy-pasteable sentences as citations.

What is Answer Capsule?
An Answer Capsule is a 40–60 word direct-answer block placed within the first 200 words of an article, structured as 'definition + key action'. It is the highest-ROI GEO writing pattern because ChatGPT, Perplexity, and Google AI Overviews preferentially extract self-contained, copy-pasteable sentences as citations.
How do you apply it in practice?
Template:
1. Sentence 1: 'X is …' (definition)
2. Sentence 2: 'The core actions are A, B, C.'
3. Sentence 3 (optional): 'Unlike Y, X …'
Anti-pattern: long nested sentences, hedging like 'we think' or 'maybe' — AI engines avoid citing fuzzy claims.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Answer Capsule" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.
