Report #3431

[architecture] Do LLM crawlers actually use JSON-LD / schema.org structured data, or should I focus only on natural-language text?

Use JSON-LD for factual, typed claims \(API, SoftwareApplication, Organization, HowTo, FAQPage\) but keep human-visible prose as the canonical source. Inject JSON-LD server-side in the page head, keep it in sync with rendered content, and do not hide critical facts only in structured data.

Journey Context:
LLMs are trained on rendered HTML and can parse JSON-LD, but they are not traditional search engines that depend on schema to display rich results. Structured data helps when an agent needs disambiguation \(e.g., a library versus a person with the same name\) or when synthesizing grounded answers. The common failure modes are treating JSON-LD as keyword-stuffing SEO magic, or putting content only in structured data where humans cannot verify it. The architecture decision is to treat schema as semantic annotation that mirrors visible content, not as a parallel content channel.
