Scaling JSON-LD: Automate Schema Markup in Eleventy

As blogs grow beyond a handful of posts, manually maintaining JSON-LD schemas and structured data markup becomes a source of technical debt and inconsistency. Eleventy users can leverage Nunjucks templating to automate schema generation entirely—define the template once and every post automatically gains valid Article, FAQ, and HowTo schemas from frontmatter alone. This approach transforms schema compliance from a manual, error-prone task into a zero-overhead system that scales with your content library.
