JSON-LD
01 Definition
JSON-LD meaning: JSON-LD is a script-based format for adding structured data to a page.
JSON-LD is a format that places structured data inside a script tag rather than mixing it into the page's visible HTML. It follows the Schema.org vocabulary. Google recommends it as the preferred way to add structured data because it is easy to add and maintain separately from page code.
Why it matters
How JSON-LD fits the work
JSON-LD is Google's recommended format for structured data, and keeping it separate from page HTML makes markup easier to add and update.
In context
The developer added a JSON-LD script in the page head describing the article's author, headline, and publish date for search engines.
Practical note
Keep JSON-LD values consistent with the visible page content. Mismatched or hidden data can make markup ineligible for rich results or look like spam.
