What Is Structured Data?

Structured data is a standardized format for providing information about a page and classifying its content. It uses vocabulary from Schema.org (a collaborative project by Google, Bing, Yahoo, and Yandex) to help search engines understand the context and meaning of your content.

The most common format is JSON-LD (JavaScript Object Notation for Linked Data), which is recommended by Google. It is embedded in a <script> tag in the page's <head> section and is invisible to users but highly valuable to search engines.

When you add structured data correctly, search engines can display rich results — enhanced search listings that include stars, prices, images, breadcrumbs, FAQs, and more. Rich results take up more space in the SERP, attract more attention, and typically achieve higher click-through rates.

Why Structured Data Matters

Rich results in Google — FAQ accordions, product pricing, review stars, breadcrumbs, and more
Improved CTR — Rich results can increase click-through rates by 20-30%
Knowledge panels — Organization markup helps Google build brand knowledge panels
Voice search — Structured data is essential for voice assistant responses
AI search optimization — FAQ and HowTo schema help AI engines extract and cite your content

How SEOAudits Validates Schema

Extract JSON-LD

During the crawl, SEOAudits extracts all <script type="application/ld+json"> tags from each page and parses the JSON content.

Detect Schema Types

SEOAudits checks the @type field of each JSON-LD block to identify which schema types are present. It looks for Organization, WebSite, Article, Product, FAQPage, HowTo, BreadcrumbList, and LocalBusiness.

Flag Missing Types

For each page, SEOAudits flags missing schema types with severity-based penalties. A page without any schema markup receives the highest penalty (-8 points). Pages with partial markup receive lower penalties.

Provide Fix Instructions

For each missing schema type, SEOAudits provides specific instructions and code examples for adding the correct JSON-LD markup. No guesswork — just copy, paste, and customize.

Example: Organization Schema

Here is an example of proper JSON-LD Organization schema markup. Place this in the <head> of every page on your site.

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Your Company Name",
  "url": "https://yourdomain.com",
  "logo": "https://yourdomain.com/logo.png",
  "sameAs": [
    "https://twitter.com/yourhandle",
    "https://linkedin.com/company/yourcompany"
  ],
  "contactPoint": {
    "@type": "ContactPoint",
    "telephone": "+1-234-567-8900",
    "contactType": "customer service"
  }
}
</script>

Example: FAQ Schema

FAQ schema enables expandable question-answer pairs in Google search results. This is also a key GEO signal for AI search engines.

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "What is structured data?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Structured data is a standardized format for providing information about a page and classifying its content using Schema.org vocabulary."
      }
    },
    {
      "@type": "Question",
      "name": "Does structured data improve SEO?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Yes. Structured data enables rich results in Google, improves click-through rates, and helps search engines understand your content better."
      }
    }
  ]
}
</script>
