Structure Data Testing Tool

The tool analyzes embedded markup and standalone data blocks to verify conformance with schema.org. It supports JSON-LD, Microdata, and RDFa, and checks for required properties (for example, Product: name, image, and price; Article: headline and datePublished). The analysis highlights missing fields, incorrect data types, and invalid values, and it provides concrete remediation guidance. It can process a single page or batch inputs, producing a structured report with issue counts, severities, and suggested fixes. The results are designed to be integrated into development and SEO workflows, enabling faster debugging and more reliable rich result eligibility. The tool is particularly valuable for e-commerce sites validating Product or Offer markup, publishers validating Article and FAQPage schemas, and corporate sites validating Organization and Website metadata. Unique value lies in its context-aware checks (valid URL formats, currency codes, ISO dates) and its ability to generate targeted recommendations that reference official schema.org guidance. Core features include type recognition, property presence checks, cross-field consistency validation, and an exportable JSON report for auditing and CI/CD use. Typical use cases include validating a new Product page before deployment, auditing existing pages for outdated or conflicting markup, and preparing data for SEO crawlers. The tool emphasizes data quality and interoperability, reducing guesswork and helping teams achieve more accurate data signaling to search engines and social platforms.
