JSON-LD Schema Markup: A Beginner's Guide
Help Google understand your pages with structured data — FAQ, Article, HowTo and more.
Schema markup is a vocabulary that describes your content to machines. Add it and search engines can display your pages as rich results — with stars, FAQs, breadcrumbs and more.
What JSON-LD looks like
{
"@context": "https://schema.org",
"@type": "FAQPage",
"mainEntity": [{
"@type": "Question",
"name": "What is schema markup?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Structured data that describes your page to search engines."
}
}]
}The most valuable types for most sites
