Schema Markup Info review
A free web tool for generating, validating, and auditing structured data across sites.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Schema Markup Info is a free, web-based tool for creating and checking structured data. It suits site owners, developers, and SEO teams that need to generate JSON-LD, validate existing markup, and review schema across live pages. The browser-based generator works without an account, while the validator supports multiple schema types and checks markup against documented Google Search requirements.
Its strongest capability is site-wide auditing. The tool crawls URLs from published sitemaps, handles JavaScript-rendered markup, and compares structured-data values with visible page content. Findings are grouped by defect and page template, helping teams identify patterns across a site rather than reviewing URLs one at a time. Feature-specific status checks also show how schema types align with Google Search eligibility, and the workflow supports JSON-LD, Microdata, and RDFa.
Schema Markup Info is a practical choice for organizations that want free generation, validation, and sitemap-based auditing in a browser. It is particularly suitable when template-level findings, rendered pages, and visible-content comparisons matter. The trade-off is its narrow focus: it addresses structured-data workflows rather than broader SEO analysis, and its web-only format may not fit teams seeking a desktop application. Choose it for accessible schema checks across individual pages or entire sites; consider another tool if your primary need is a wider SEO platform or a different operating environment.
