Overview

When tagging your website with structured data, it’s not just about describing what’s on the page—it’s also about linking it to trusted external sources that validate your content. That’s where referencing unambiguous entities, like Wikipedia, comes in.

This feature in Milestone Schema Manager lets you add authoritative references to your schema types using the “Same As” or “Additional Type” properties. Doing so can increase the trustworthiness of your schema and may positively influence how your content appears in search features like the Google Knowledge Graph.

Why Use Wikipedia References in Schema?

Search engines rely on structured data to understand and verify what your content is about. By linking your schema to a known entity—like a verified Wikipedia page—you:

• Boost the credibility of your data
• Help search engines confidently connect your content to real-world concepts
• Improve your chances of being featured in rich results or knowledge panels

Step-by-Step: Referencing Wikipedia in Schema

Let’s walk through the process using the Organization schema as an example.

Start with an Organization Schema

Assume you’re tagging your website using the Organization schema type. You want to include a reference to your company’s Wikipedia page to clearly define its identity.

Click on ‘Add Properties’ inside the schema editor.

Choose either:

• Same As (for identity verification)
• Additional Type (to indicate other relevant types or roles)

Then click on ‘Refer Wikipedia’ next to the selected property.
