What is Schema Markup?

Schema Markup is a very powerful tool in the world of SEO. It’s crucial to how search engines interpret and display website content. A schema markup, often referred to as structured data, is a type of microdata added to a webpage to create an enhanced description (also called a rich snippet). It shows up in search results. It was collaboratively developed by Yandex, Yahoo!, Bing, and Google to help search engines comprehend the context of content on websites.

Put simply, Schema markup is a code (semantic vocabulary) added to a website to help search engines return more informative results for users.

Semrush.com says the following about the term “Schema Markup”:
