An Introduction to Structured Data Markup

Structured data helps search engines understand content context and enables rich results in search listings. This resource covers schema implementation strategies and best practices for maximizing structured data benefits.

Schema Types and Applications

Different schema types serve different purposes. Article, Product, LocalBusiness, FAQ, HowTo, and other schemas each provide specific functionality. Selecting appropriate schema types for your content enables relevant rich results and improves search engine understanding.

Implementation Best Practices

JSON-LD provides the recommended format for schema implementation. Proper nesting, complete required fields, and accurate data all contribute to schema effectiveness. Testing with Google's Rich Results Test ensures proper implementation before deployment.

Rich Results Impact

While schema isn't a direct ranking factor, rich results improve click-through rates. Review stars, FAQ accordions, recipe cards, and other rich results make listings more prominent and informative. This visibility advantage can significantly impact traffic from search.

This resource provides practical guidance for implementing structured data that improves search presence.

The three ideas behind structured data

Structured data feels abstract until you separate it into three parts. The vocabulary is the agreed list of types and properties; for search that means schema.org, a shared standard backed by Google, Microsoft, Yahoo, and Yandex. The syntax is how you write that vocabulary into a page: JSON-LD, microdata, or RDFa. The entity is the actual thing you are describing, a specific product, a specific article, a specific business. Get those three straight and every schema decision becomes easier. When you are ready to produce your first block, our structured data generator workflow walks through it field by field.

Reading a JSON-LD block

Here is a minimal Article block. Notice that it is a single script element, kept separate from the visible HTML, which is exactly why JSON-LD is the format Google recommends.

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "An introduction to structured data",
  "image": "https://example.com/cover.png",
  "author": { "@type": "Person", "name": "Jane Doe" },
  "datePublished": "2026-07-27"
}
</script>

The @context tells parsers you are using schema.org, @type names the entity, and the remaining keys are properties. Every value here should match something a reader can see on the page.

The three syntaxes compared

What's changed since this introduction

The fundamentals are stable, but three things have moved. JSON-LD is now the clear default, and most guides that still teach microdata first are dated. Google also consolidated its structured data documentation and retired some rich results: FAQ and HowTo are now limited to a narrow set of sites, so a beginner should not expect those to appear automatically. Finally, entities matter more than ever because AI powered results and knowledge panels lean on the same schema.org signals, and properties like sameAs help connect your entity to known references.
