jekyll-structured-content

jekyll-structured-content is a Jekyll plugin that emits clean, standards-compliant JSON-LD structured data from your existing frontmatter — no theme changes required. It handles BlogPosting, WebPage, ProfilePage, CreativeWork, and FAQPage schema types.

Why This Exists

Structured data helps search engines and AI systems understand what your content is, who wrote it, and what questions it answers. Most full SEO plugins bring too much with them — meta tag management, Open Graph, sitemaps. This plugin does one thing: emit valid JSON-LD from your Jekyll frontmatter and leave everything else alone.

• RubyGems: rubygems.org/gems/jekyll-structured-content

Installation

Add to your Gemfile:

gem "jekyll-structured-content", "~> 0.2.0"

Add to _config.yml:

plugins:
  - jekyll-structured-content

Then run bundle install.

Usage

Place the tag inside a <script> block in your layout:

<script type="application/ld+json">{% schema_json_ld post %}</script>

Supported types: post, page, project.

For FAQ schema, add an faq array to your frontmatter and emit it separately:

<script type="application/ld+json">{% faq_json_ld %}</script>

faq:
  - question: "What does this plugin do?"
    answer: "It emits JSON-LD structured data from Jekyll frontmatter."
