Glossary Term

Structured Data

Machine-readable markup, like JSON-LD, that states what a page or entity is directly, instead of leaving a search engine or AI system to infer it from prose.

Structured data declares identity explicitly: this page is an Article, this record is a DefinedTerm, this entity is an Organization with this name and this URL. On a JSON+PHP flat-file site, the same JSON record that drives the visible page also drives its JSON-LD output, so the structured layer never drifts out of sync with what a human reader sees.

Structured data does not rescue weak content. It amplifies clarity that already exists, and removes ambiguity that would otherwise cost a citation.

In Practice

Every glossary term on this site outputs a DefinedTerm JSON-LD block alongside the human-readable definition, so an AI system parsing the page gets the same term, short definition, and URL whether it reads the markup or the prose.

Worth Knowing

Structured data is infrastructure, not decoration. Treating it as an SEO checkbox added after the fact produces markup that's technically valid but disconnected from the actual content model.

Related Terms

AI Search

Discovery that happens through AI systems summarizing, citing, and recommending sources, rather than through a traditional ranked results page.

Digital Asset

Structured digital property, like a domain, a dataset, or a glossary entry, that appreciates in value as the rest of the ecosystem links to, cites, and builds on top of it. The opposite of content, which depreciates the moment it's published.

Topical Authority

The trust signal search engines and AI systems assign to a source based on how completely and consistently it covers a topic, built up over time rather than earned from a single page.
