What is Schema Markup?

Schema markup (also called structured data) is code added to your HTML that helps search engines understand the meaning and context of your content — not just the words, but what they represent. It uses vocabulary from schema.org, a collaborative project created by Google, Microsoft, Yahoo, and Yandex.

When search engines understand your content at a semantic level, they can display it as rich results in the SERPs — visually enhanced listings that stand out from standard blue links. Rich results include star ratings for products, FAQ accordions directly in search results, step-by-step instructions for how-to content, breadcrumb trails, and knowledge panel information for businesses. Studies consistently show that rich results achieve 20–30% higher click-through rates than standard results.

JSON-LD (JavaScript Object Notation for Linked Data) is Google's preferred format for schema markup. Unlike Microdata, JSON-LD lives in a <script> tag in your page's <head> — it doesn't require modifying your visible content HTML, making it far easier to implement and maintain.

Schema Types and Their Rich Result Potential

  • Article / BlogPosting — Enables article rich results with author, date, and image in Google Discover and News.
  • LocalBusiness — Populates Google's knowledge panel with address, hours, phone, and map. Critical for local SEO.
  • Product — Displays price, availability, and star ratings directly in search results — highest CTR impact for e-commerce.
  • FAQPage — Shows FAQ accordion directly in SERPs, doubling your SERP real estate.
  • HowTo — Displays step-by-step instructions with images in search results.
  • BreadcrumbList — Shows your site's navigation path in the URL section of search results.
  • Person — Establishes E-E-A-T (Experience, Expertise, Authority, Trust) signals for authors.
  • WebSite — Enables the Sitelinks Searchbox in your branded search results.
