JSON-LD
Fields change with the type. Check the output with the schema checker.
What JSON-LD buys you
JSON-LD is the structured data format Google prefers. It does not change your position directly; it makes your page eligible for rich results and legible to every machine that reads it, including AI assistants.
Where the block goes
Anywhere in the page, head or body, as a <script type="application/ld+json"> tag. One trailing comma kills the whole block, so validate the JSON before deploy.
