With schema markup

Structured data is how your website introduces itself to machines.

What is Schema Markup?

  • Shared vocabulary from Schema.org — maintained by Google, Microsoft, Yahoo, Yandex
  • Tells search engines what your content means, not just what it says
  • Three formats: JSON-LD, Microdata, RDFa — JSON-LD wins (recommended by Google)
  • Just a <script type="application/ld+json"> tag — no HTML changes needed

Why Should You Care?

  • Rich results — ratings, FAQs, prices directly in search
  • AI search — Perplexity, ChatGPT Search, Google AI Overviews rely on structured data
  • CTR boost — not a direct ranking signal, but rich results get more clicks

Your First Schema:
Organization

{
  "@context": "https://schema.org",
  "@type": "Organization",
  "name": "Acme Corp",
  "url": "https://acme.com",
  "logo": "https://acme.com/logo.png",
  "sameAs": [
    "https://twitter.com/acme",
    "https://linkedin.com/company/acme"
  ],
  "contactPoint": {
    "@type": "ContactPoint",
    "telephone": "+1-800-555-0100",
    "contactType": "customer service"
  }
}
@context + @type are always required — every schema starts here
sameAs links your social profiles — helps build your Knowledge Graph entry

Highest-ROI Schema: FAQPage 

{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "What is schema markup?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Schema markup is structured
        data you add to your website..."
    }
  }]
}
mainEntity is an array of Questions
acceptedAnswer must be an object, not a string!
FAQ rich result in Google

HowTo
Step-by-step instructions

Schema.org has 800+ types. These ~10 cover 90% of real-world use cases.

Spot the Bug

❌ Wrong
{
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "What is schema?",
      "acceptedAnswer": "Schema is
        structured data that..."
    }
  ]
}
✅ Correct
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [
    {
      "@type": "Question",
      "name": "What is schema?",
      "acceptedAnswer": {
        "@type": "Answer",
        "text": "Schema is structured
          data that..."
      }
    }
  ]
}
1
Missing @context — parser doesn't know you're using Schema.org
2
acceptedAnswer is a string — must be an Answer object
3
Missing @type: "Answer" on the nested object

Things That Will
Bite You

  • Validation ≠ rich results — Google decides eligibility separately; passing validation is necessary but not sufficient
  • SPAs & client-side rendering — Googlebot may not execute your JS; use SSR, SSG, or prerendering for schema
  • Schema drift — content changes but schema stays stale (wrong prices, outdated FAQs, closed locations)
  • Duplicate schemas — multiple conflicting schema blocks on one page confuse parsers
  • No good all-in-one validator — I forked Adobe's structured-data-validator to support 140+ types with automatic subtype inheritance
