WordPress Structured Data Guide for SEO

WordPress Structured Data Guide

Structured data has grown beyond rich snippets. In 2026, Google uses entity data to power AI Overviews, knowledge panels, and conversational search results. Building comprehensive structured data is now an SEO foundation, not just an enhancement.

Entities vs Keywords

Google's Knowledge Graph is built from entities — people, places, organizations, concepts. Structured data helps Google understand that your content is about a specific entity, making it eligible for knowledge panel inclusions and AI-generated answer citations.

Organization Markup

Every site should have Organization (or LocalBusiness) schema in the site header:

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Company",
  "url": "https://yoursite.com",
  "logo": "https://yoursite.com/logo.png",
  "sameAs": ["https://twitter.com/yourco", "https://linkedin.com/company/yourco"]
}

The sameAs array connects your entity to social profiles and Wikipedia/Wikidata entries, strengthening your entity in the Knowledge Graph.

Author Entity Markup

Link authors to their Person entity with name, URL, sameAs links, and knowsAbout fields. Google uses author entities to assess E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) signals.

Article Markup Best Practices

• Always include dateModified alongside datePublished — update it when revising content
• Link author to a Person entity, not just a string name
• Include a high-quality image for article cards in Google Discover
• Use speakable to mark sections appropriate for voice search reading

Validating Structured Data

Beyond Google's Rich Results Test, use Schema.org Validator and check Google Search Console's Enhancements section for structured data coverage and errors at scale.
