GlossaryStructured Data

Structured Data

Structured data is standardized, machine-readable annotation of web content, most commonly Schema.org vocabulary expressed as JSON-LD.

Also known as: semantic-markup · machine-readable-metadata

Why it matters

Unstructured HTML forces parsers to infer; structured data states intent explicitly. That clarity powers rich results, knowledge panels, and safer AI citations when aligned with visible text.

How it works

Embed a JSON-LD graph describing entities and properties. Crawlers merge it with HTML signals. Rich result eligibility depends on type, policy compliance, and content match. Keep graphs minimal, describe what is on the page, not keyword wishlists.

Common mistakes

  • Treating structured data as a ranking cheat code.
  • Bloating graphs with every possible type on one URL.
  • Forgetting to update `dateModified` when content materially changes.
  • Serving different structured data to bots vs users (cloaking).

Best practices

  • Mirror visible content exactly in structured properties.
  • Centralize generation in one metadata engine per site.
  • Test with Rich Results Test after template changes.
  • Document which templates emit which types.

Learn Domains perspective

Two product pages describing the same feature with different names confuses search engines and AI assistants alike. Learn Domains keeps titles, descriptions, and structured data aligned across your vault's drafts and live pages, one clear label per product fact.
