Structured Data / JSON-LD Validator

Enter any public URL to extract and validate every <script type="application/ld+json"> block on the page. The tool checks for valid JSON syntax, verifies required and recommended schema.org properties for each @type, and surfaces missing fields that can prevent rich result eligibility in Google Search.

Related SEO tools: Structured data and Open Graph tags work together to control how your pages appear in search results and on social platforms. After validating your JSON-LD, use the Open Graph & Social Card Previewer to audit the og:* tags that shape the card displayed alongside rich results. Before either audit matters, confirm that search engines can access the page using the Robots.txt Analyzer.
