Structured Data & Social Tag Checkers
Structured data (Schema.org, usually as JSON-LD) describes a page in a form machines can parse without guessing. Google uses it for rich results, and AI assistants use it to confirm who is behind a site. Social tags such as Open Graph and X Cards control the preview when someone shares your link.
These checkers validate the markup that is actually on the page. They do not invent markup or promise a rich result: Google decides whether to show one.
