What Schema Markup Info is
Schema Markup Info is a free web tool for creating schema markup and checking existing structured data. Its browser-based generator creates JSON-LD and includes forms for types such as Product, LocalBusiness, Article, FAQ, WebSite, and HowTo. The Product generator can export as a script tag, JSON-LD, WordPress, or Tag Manager output. The validator parses JSON-LD, microdata, and RDFa, then checks Google Search feature requirements and whether marked-up values match visible page content. Reports include values, page location, visibility, and confidence. It can follow redirects and render JavaScript-built pages. For site-wide checks, its audit reads a sitemap, crawls reachable pages, and groups defects to help identify template-level fixes; crawls have a page budget and a 20-minute limit. The service links to Google’s Rich Results Test and the Schema.org validator. The maker says its 19-feature registry was last verified on 2026-08-29, with all entries provisional. It cannot predict whether Google will show a rich result or what Google itself sees.
