What is Schema Markup?
Schema markup is a standardized semantic vocabulary (defined at Schema.org) added to HTML code to help search engines understand the explicit context and entities within your content. When search engines interpret structured data, they can enhance your organic search listing with Rich Snippets (such as FAQ accordions, review stars, and author badges), significantly boosting organic Click-Through Rate (CTR).
Why JSON-LD is Google's Preferred Format
Google explicitly recommends using JSON-LD (JavaScript Object Notation for Linked Data). JSON-LD scripts are cleanly embedded inside a single <script type="application/ld+json"> block without interfering with visible HTML layout.
Example: Article Schema with JSON-LD
<script type="application/ld+json">
