Structured data with JSON-LD: only what is true
本文尚无中文版本；显示原文。
JSON-LD in a script block describes the page with schema.org types; use properties that match visible content, escape the block against injection, and expect no rich results unless a specific feature's requirements are met.
What it is
JSON-LD is JSON with an @context (schema.org) and @type; placed in <script type="application/ld+json">, it describes the page's main entity — an Article with headline, datePublished, dateModified, inLanguage, license; a WebSite with a SearchAction. Google's documentation recommends JSON-LD as the format and requires that markup reflect the page content.
Why it matters
Structured data helps machines identify what a page is about and which dates and licence apply. It does not raise rankings by itself, and invented data (fake ratings, authors, reviews) violates guidelines.
How to apply
- Emit only properties you can populate from real data: title, summary, dates from the record, language, licence URL, canonical
@id/url. - Name the author only when there is a real author entity; otherwise use text properties such as
creditText. - Escape
<and&in the serialised JSON so that a</script>inside a title cannot end the block; the block is data, not executed script, so a strict CSP still allows it. - Validate the markup with a testing tool, but treat "eligible for rich results" as unrelated to correctness.
Pitfalls
Ratings, reviews or images that do not exist on the page. Types outside their defined property ranges produce warnings. Duplicating the entire article text inside the markup adds weight without value.
