Spec score 8.6 #2 of 24 in Schema Markup Tools

What it is

BlueGrid Schema Validator is a web tool for generating JSON-LD markup and checking it against schema.org vocabulary and Google rich-result requirements. Its form-based generator builds markup for types including LocalBusiness and trade subtypes, Organization, Person, Service, FAQPage, Article, BlogPosting, NewsArticle, Product, BreadcrumbList, Event, and Review. The output updates as the form is completed and can be copied inside a script-tag wrapper. For validation, it checks JSON syntax, @context and @type, required and recommended properties, and common formats such as dates, URLs, and prices. Missing properties can lead to corrected JSON-LD with placeholders and a completeness score. Users can also submit a page URL for its JSON-LD to be fetched through a public proxy and analyzed in the browser. The maker says pasted markup is validated in the browser and generated content is not uploaded. Rich-result preview is included, and results can be shared by link or the validator embedded on another site. The maker cautions that valid markup can qualify a page for rich results but cannot ensure Google displays one.
