Paste your JSON-LD structured data below to instantly check for syntax errors and common required fields.
Schema markup (structured data) is standardized code, usually written as JSON-LD, that describes a page's content in a format search engines can parse directly. It's the mechanism behind rich results like star ratings, FAQ dropdowns, recipe cards, and breadcrumb trails in search listings.
Because schema is written in strict JSON, a single misplaced comma or missing brace can invalidate an entire block — silently losing you eligibility for the rich result it was meant to enable.
Valid JSON just means the syntax is correctly formatted. Valid schema additionally means the structure matches what schema.org and search engines expect for that specific @type, including required properties.
No. It's most valuable on pages eligible for rich results — articles, products, FAQs, reviews, recipes, local business listings, and similar structured content types.
No. Valid schema makes a page eligible for rich results, but search engines still decide whether and when to display them based on many other quality and relevance signals.
This tool checks one JSON-LD object at a time. If your page has multiple script blocks, validate each one separately for the clearest results.
