Schema markup is a code (semantic vocabulary) that you place on your website to help search engines return more informative results for users. It is a collaborative effort by Google, Bing, Yahoo!, and Yandex to create a shared structure for data on the web.
Search engines crawl your site to read the content. But they don't always understand what that content means. For instance, if your site displays "June 15, 2026," search engines don't automatically know if that's a birthdate, an event date, or a product release date. Schema markup provides this context.
Depending on your content, you can implement different schema types:
The recommended format for schema markup is JSON-LD. You can use Google's Structured Data Markup Helper to generate the code. Once generated, add the script tag containing the JSON-LD code into the <head> or <body> section of your HTML.
While schema markup is not a direct ranking factor, the rich snippets it enables can drastically improve your search visibility and traffic. Start adding structured data to your key pages today.
