answer capsule
A self-contained paragraph-level span of text that answers a specific question independently, without requiring surrounding context to be understood.
An answer capsule is the atomic unit of citable content. A well-formed capsule has: a clear question framing (either as an H2/H3 subhead or as the first sentence), a direct answer, and 2–4 sentences of supporting context that make the capsule hold up when extracted from the surrounding document.
Language models quote capsules. They rarely quote full articles, and they never quote fragments that require external context to make sense. Writing in capsules is the single biggest compositional change that moves citation rate.
A useful test: read one paragraph of your content out loud. If someone who hasn't read the rest of the page can understand what you're claiming and why, it's a capsule. If they need the previous paragraph to parse it, it's not — and an LLM will skip over it in favor of something more standalone.
In AIRRNK
AIRRNK's content scanner identifies capsule candidates on every page and surfaces paragraphs that almost-are-but-aren't capsules — usually missing a single context sentence. These are some of the highest-lift, lowest-effort fixes in the system.
- Citation Density
A measure of how many distinct, quotable 100–400 token chunks appear per 500 words of content on a page.
- Generative Engine Optimization
The practice of making a website more likely to be cited by AI answer engines (ChatGPT, Claude, Perplexity, Google AI Mode) rather than simply ranked on a traditional search results page.
- Schema Markup
Structured data embedded in a page (usually as JSON-LD) that describes what the page is about in a machine-readable vocabulary defined at schema.org.
