Schema Markup Checker &
JSON-LD Inspector.
Inspect JSON-LD structured data scripts, validate schema types, and discover entity attributes that help search engines and AI agents interpret your content.
What This Analyzer Checks
Every check is evaluated by our deterministic engine according to Google standards and AI search requirements.
JSON-LD Script Discovery
Scans document head and body for <script type='application/ld+json'> blocks.
Schema Type Classification
Identifies Organization, WebSite, Article, FAQPage, Product, LocalBusiness, and BreadcrumbList types.
Syntax & JSON Validation
Detects malformed JSON syntax, trailing commas, and unclosed JSON-LD script tags.
Entity Attribute Completeness
Checks for required entity attributes like @type, @id, name, url, logo, and sameAs links.
Rich Snippet Eligibility
Evaluates eligibility for Google Search rich results, knowledge panels, and AI citations.
Schema Context & Vocabulary
Ensures valid @context declarations (https://schema.org) and standard vocabulary usage.
Why Structured Data Powers Knowledge Graphs and AI Search
Structured data translates raw web content into machine-readable semantic facts. By implementing valid JSON-LD schema markup, you help Google, Bing, ChatGPT, and Perplexity recognize your organization, products, FAQs, and articles — qualifying your site for enhanced rich snippets and AI search citations.

Frequently Asked Questions About This Checker
What is Schema.org structured data and why is it important?
Schema.org structured data provides explicit semantic clues about web content in JSON-LD format. It enables search engines and AI models to understand entities, organizations, and relationships, powering Google Rich Results.
Why is JSON-LD preferred over Microdata or RDFa?
Google officially recommends JSON-LD because it is encapsulated within a distinct <script> block, decoupling structured data from front-end styling and preventing syntax breakage during website redesigns.
Does valid schema markup guarantee Rich Snippets on Google?
No. Valid schema markup establishes technical eligibility for rich results, but Google displays enhanced snippets at algorithmic discretion based on query intent, domain authority, and guideline compliance.
