BlueGrid Schema Validator vs TechnicalSEO Schema Markup Generator

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.

TechnicalSEO Schema Markup Generator is a free web tool for creating Schema.org structured data as JSON-LD markup. You choose the Schema.org markup type, then complete the required item properties and any additional properties provided by the generator. The resulting JSON-LD can be copied and pasted into an HTML page. The page links to Google’s Structured Data Testing Tool and Rich Results Test, giving you named destinations for checking the markup. It does not describe automatic publishing, so placing the generated code in a page remains a separate step. TechnicalSEO.com lists this generator among SEO tools covering areas such as crawling, rendering, mobile SEO, international SEO, local SEO, and SERP and ranking. The page also suggests Schema App for an end-to-end schema markup solution. Merkle launched TechnicalSEO.com in April 2015 as a resource for its SEOs, industry members, and clients. The generator runs on the web and has a free plan.
