Schema.org and JSON-LD Explained
Learn how to implement structured data to win Rich Snippets, FAQ dropdowns, and star ratings in Google Search.
Have you ever searched for a recipe and noticed that some results include a photo, star rating, and cooking time directly in the search results? Those are called Rich Snippets, and they are powered by Schema.org structured data.
What is Schema.org?
Schema.org is a collaborative vocabulary founded by Google, Microsoft, Yahoo, and Yandex. It provides a standardized way to describe the content of your website to search engines. Instead of forcing Google to guess that “John Doe” is an author and “4.5” is a rating, you explicitly define those entities in code.
Why use JSON-LD?
In the past, structured data was implemented using Microdata, which required wrapping HTML elements in messy data attributes. Today, Google explicitly recommends JSON-LD (JavaScript Object Notation for Linked Data).
JSON-LD allows you to inject a single <script type="application/ld+json"> block into your <head> containing all the structured data, entirely separate from your visual HTML.
High-Impact Schema Types
1. FAQPage Schema
If you have a Frequently Asked Questions section, implementing FAQPage schema allows Google to display your questions and answers directly underneath your search result in an accordion dropdown. This massively increases your visual footprint on the SERP.
2. Product & Review Schema
Crucial for eCommerce. This schema powers the price, availability (In Stock), and star ratings that appear next to product listings.
3. LocalBusiness Schema
If you have a physical storefront, LocalBusiness schema ensures your address, opening hours, phone number, and geographic coordinates are perfectly understood by Google Maps and local search algorithms.
4. Article Schema
Used on blog posts and news articles to define the headline, author, publish date, and featured image, making the article eligible for the Google News carousel.
