Structured data
validator

Enter a URL or paste JSON-LD to instantly check syntax, type, and the required and recommended properties for rich results.

We fetch the page server-side and extract its JSON-LD structured data.

Fetch any public URL, or paste JSON-LD to validate staging and unreleased markup privately.

Catch schema mistakes search engines silently ignore

Required vs recommended

Missing a required property can disqualify a rich result entirely; missing a recommended one just limits how rich it can be.

Empty values count as missing

An author with an empty name or a blank headline passes JSON parsing but fails Google's checks. This tool flags both.

Live URL or private paste

Fetch a public page to pull its JSON-LD automatically, or paste markup directly to validate staging and unreleased content.
