Sitemap & JSON-LD Toolkit

Generates sitemaps and structured data from your content model, and validates the output.

Structured data is easy to emit and easy to emit wrongly. Search engines ignore invalid JSON-LD silently, so mistakes go unnoticed for months.

What it generates

  • sitemap.xml with lastmod from real modification dates, excluding drafts and noindex pages
  • Article, BlogPosting, BreadcrumbList, and Person JSON-LD from your existing types
  • Canonical tags with per-document overrides

Validation

Schemas are checked against schema.org definitions at build time. Emitting a BlogPosting without datePublished fails the build rather than shipping data that is quietly discarded.
