BlueGrid Schema Validator vs SchemaValid

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.

SchemaValid is a browser-based toolkit for JSON-LD, structured data and technical SEO. Its tools include schema validation, sitemap and robots.txt utilities, plus tools for text and content, AI search, analytics, campaigns and other tasks such as IBAN validation. The validator checks a live URL or pasted JSON-LD and reports an SEO score, errors, warnings and rich-results readiness. URL checks provide scorecards for 16 schema types, including Organization, Product, Article, Recipe, Event, FAQPage, JobPosting, Course, VideoObject and SoftwareApplication; the limit is five URL checks per minute per visitor. Pasted-code validation runs locally without uploading or storing the code or tying it to an account. The AI Search Readiness Checker scores a page out of 100 across eight categories, using the page and its robots.txt, sitemap.xml and llms.txt. A robots.txt editor offers a live preview for crawler rules, AI-bot access and sitemap settings. The tools are free without registration, though availability may change.
