By Wonda Editorial Team
Search engines in 2026 rely on structured signals to understand what your content actually means, not just what it says. If you've been wondering what is schema markup and why it keeps surfacing in SEO conversations, you're in the right place. This guide breaks it down: what it is, the types available, practical code examples, and exactly how to implement and validate it on your site.
What Is Schema Markup in SEO?
Schema markup is structured data, a layer of code (typically JSON-LD) added to your HTML that explicitly tells search engines what your content represents. Instead of leaving Google to interpret your page through text alone, schema uses a standardized vocabulary from Schema.org to label elements: a product, an event, a review, a business, an article, and more.
The payoff? Search engines index your content more accurately and often reward it with rich results, enhanced listings displaying star ratings, pricing, event dates, or FAQs directly on the results page. These enriched listings stand out visually and directly improve click-through rates.
Common Types of Schema Markup
Schema.org defines hundreds of types, but a handful cover the vast majority of use cases:
| Schema Type | What It Does | Best For |
|---|---|---|
| Article / Blog Post | Surfaces headlines, publication dates, and authors | Content-driven sites |
| Product & Offer | Displays pricing, availability, and reviews in listings | E-commerce stores |
| FAQ & How-To | Creates interactive expandable snippets in search | Q&A pages, tutorials |
| Review / AggregateRating | Enables star ratings in listings | Any reviewed product or service |
| Event | Highlights event names, dates, and locations | Event promoters, venues |
| Organization / Local Business | Provides address, hours, and contact info | Local SEO |
| Recipe | Surfaces ingredients, cook times, and ratings | Food and culinary content |
| Video | Displays video thumbnails and metadata | Media publishers |
Learn more about how FAQ schema markup can increase CTR. Choosing the right type depends entirely on your content, a local restaurant benefits most from Organization and Review markup, while an online store needs Product and Offer.
Schema Markup Examples in HTML
Google officially recommends JSON-LD because it keeps structured data separate from your visible HTML, making it easier to manage and less prone to breaking your layout.
JSON-LD Example: Organization
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Your Company Name",
"url": "https://www.example.com",
"logo": "https://www.example.com/logo.png",
"contactPoint": {
"@type": "ContactPoint",
"telephone": "+1-800-555-1234",
"contactType": "Customer Service"
}
}
</script>JSON-LD Example: Article
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "Article",
"headline": "What Is Schema Markup?",
"datePublished": "2026-02-01",
"author": {
"@type": "Person",
"name": "Your Name"
}
}
</script>Microdata (using itemscope, itemtype, and itemprop) embeds attributes directly into HTML elements. While functional, it's harder to maintain. For most sites, JSON-LD placed in the <head> section is the cleanest, most scalable approach.
How to Add Schema Markup in WordPress
The safest approach for WordPress is using a dedicated plugin rather than editing theme files directly. Popular options include:
- Rank Math SEO
- Yoast SEO
- Schema & Structured Data for WP & AMP
Implementation Steps
- Install your chosen plugin via Plugins → Add New and activate it.
- Configure a default schema type for your content (e.g., Article for blog posts, Product for WooCommerce pages).
- Follow the setup wizard, new content will automatically receive appropriate markup.
- Clear your site cache and validate the output using Google's Rich Results Test.
Using a Schema Markup Generator
If you're not using a plugin or need schema for a specific page, a generator simplifies the process, no coding knowledge required:
- Select your schema type, Article, FAQ, Event, Product, etc.
- Fill in required fields, headline, description, URL, image, and type-specific properties.
- Generate the code, the tool outputs valid JSON-LD, eliminating manual formatting errors.
- Validate the output, paste it into Google's Rich Results Test before deploying.
- Add it to your page, insert the script block into your page's
<head>or your CMS's custom code field.
Generators are particularly useful for one-off implementations or for teams that want to prototype schema before automating it at scale.
How to Validate Your Schema Markup
Implementing schema incorrectly means search engines may ignore it entirely, validation is non-negotiable. Two tools cover the essentials:
- Google's Rich Results Test (search.google.com/test/rich-results), Enter your URL or paste code directly. It identifies errors, warnings, and shows whether your page qualifies for rich results.
- Schema.org Validator (validator.schema.org), Validates JSON-LD, Microdata, or RDFa against the official specification, independent of Google's interpretation.
robots.txt, otherwise these tools can't crawl your markup. Re-validate after each significant content update, as schema isn't a one-time task.How Wonda Keeps Your Schema and Content Strategy Current

What is schema markup and why does it matter for SEO?
Schema markup is structured data code, typically JSON-LD, added to your HTML that tells search engines exactly what your content represents. It uses the standardized Schema.org vocabulary to label elements like products, events, reviews, and articles. The result is more accurate indexing and eligibility for rich results such as star ratings, pricing, and FAQs directly in search listings, which improve click-through rates.
Should I use JSON-LD or Microdata for schema markup?
Google officially recommends JSON-LD because it keeps structured data separate from your visible HTML, making it easier to manage and less likely to break your page layout. Microdata embeds attributes directly into HTML elements and is harder to maintain. For most sites, placing JSON-LD in the head section is the cleanest and most scalable approach.
How do I add schema markup to a WordPress site?
The safest method is using a dedicated plugin such as Rank Math SEO, Yoast SEO, or Schema & Structured Data for WP & AMP. Install and activate the plugin, configure a default schema type for your content, follow the setup wizard, then clear your cache and validate the output with Google's Rich Results Test.
How do I validate schema markup after adding it?
Use two tools: Google's Rich Results Test (search.google.com/test/rich-results) to check for errors and confirm rich result eligibility, and the Schema.org Validator (validator.schema.org) to validate your code against the official specification. Re-validate after every significant content update, as schema is not a one-time task.
What are the most common types of schema markup?
The most widely used types include Article and BlogPosting for content sites, Product and Offer for e-commerce, FAQ and HowTo for tutorials and Q&A pages, Review and AggregateRating for star ratings, Event for dates and venues, Organization and LocalBusiness for local SEO, Recipe for culinary content, and Video for media publishers.
