What is Schema Markup?

Schema markup (also called structured data) is code you add to your website that helps search engines understand your content better. It uses a standardized vocabulary from Schema.org to describe things like articles, products, events, recipes, and more.

When search engines understand your content, they can display rich snippets in search results - those enhanced listings with star ratings, prices, images, FAQ dropdowns, and other eye-catching elements that can significantly boost your click-through rates.

Why Use JSON-LD Format?

JSON-LD (JavaScript Object Notation for Linked Data) is Google's recommended format for structured data. Here's why it's the go-to choice for most SEOs.

  • It's separate from your HTML, so you can add or update it without touching your page content.
  • It's easier to read and debug than Microdata or RDFa alternatives.
  • You can place it anywhere on the page - usually in the head or at the end of the body.
  • It works great with JavaScript frameworks and dynamic content.

Common Schema Types for SEO

Different schema types trigger different rich results in Google. Here are the most commonly used ones.

  • Article/BlogPosting - For news articles and blog posts. Can show publish dates and author info.
  • Product - Shows price, availability, and review ratings in search results.
  • FAQPage - Creates expandable FAQ sections right in the search results.
  • LocalBusiness - Displays business hours, address, and contact info.
  • HowTo - Shows step-by-step instructions with images.
  • Recipe - Displays cook time, calories, and ratings.
  • Event - Shows event dates, location, and ticket info.
  • BreadcrumbList - Creates breadcrumb navigation in search results.

How to Use This Validator

This tool checks your JSON-LD schema for common issues that could prevent your rich snippets from appearing. Here's how to use it.

  1. Copy your JSON-LD schema markup from your website (look for script tags with type="application/ld+json").
  2. Paste it into the text area above.
  3. Click "Validate Schema" to run the checks.
  4. Review any errors, warnings, and recommendations.
  5. Use the "Format JSON" button to clean up messy code.
