How to add schema markup to html?

Adding schema markup to raw HTML is a straightforward process when using the JSON-LD format. You begin by determining the specific entity type you want to mark up, such as an Article, LocalBusiness, Product, or Organization, by referencing the vocabulary guidelines on Schema.org. Next, build your structured data code inside a dedicated script tag with the type attribute set to application/ld+json. Inside this JSON object, define the schema context, the main entity type, and all relevant properties such as name, image, description, address, price, or author. Once your script block is written, paste it directly into the HTML code of your webpage—ideally inside the head section, though placing it near the bottom of the body section also works seamlessly. After saving and publishing your HTML page, verify that search engines can read the markup properly by inspecting the URL using Google's official Rich Results Test or the Schema.org Validator tool to clear any code formatting errors.
