What is JSON-LD Schema Markup?

JSON-LD (JavaScript Object Notation for Linked Data) is the recommended way to add structured data to your website. You embed a small block of code in your page's <head> that tells Google exactly what your page is about — whether it's a product, a person, an article, or an FAQ. Google then uses this to display rich results in search: star ratings, pricing, FAQs, and more.

Why Structured Data Matters for SEO

  • — Rich snippets — star ratings, pricing, reviews — significantly increase click-through rates from search results.
  • — Google uses schema to better understand your content and surface it for the right queries.
  • — Product pages with proper schema can appear in Google Shopping and knowledge panels.
  • — SoftwareApplication schema helps your product show up with ratings and pricing directly in search.
  • — Missing or invalid schema means Google ignores it entirely — no rich results.
