Structured Data for Schema.org helps you add valid Schema.org markup to your WordPress content. This improves how search engines understand your content and may qualify for Google Rich Snippets (depending on schema type and page structure).

Supported Schema Types

  • HowTo — Step-by-step tutorials (Google Rich Result eligible, 1 per page recommended)
  • FAQPage — Questions & Answers (Google Rich Result eligible, 1 per page limit enforced)
  • ItemList — Ordered/unordered lists (Google Rich Result eligible)
  • CreativeWork — General content (SEO only, no Rich Result)

Important: Google Rich Results

Not all schema types guarantee Rich Snippets. Google has specific requirements:

  • HowTo: Best results with ONE main tutorial per page
  • FAQPage: Only ONE FAQPage schema per page is eligible for Rich Results (plugin enforces this)
  • ItemList: Works well for top-10 lists, product collections
  • CreativeWork: Helps SEO but does not trigger Rich Results

This plugin generates valid Schema.org markup. Rich Result eligibility depends on your content structure and Google’s algorithms.

Usage

HowTo Schema

[schema type="HowTo" name="How to Draw a Rune" time="5M"]
Step 1: Clear your mind
Step 2: Focus on your question

[schema type="FAQPage" name="Rune FAQ"]
What are runes? | Ancient Germanic alphabet symbols
How do I use them? | Focus on a question and draw randomly
