Schema markup, also known as structured data, is a code standard used to help search engines understand and categorize webpage content. It is a semantic vocabulary (code) that helps search engines characterize and categorize the content of web pages. Schema markup is a way to add additional information to your websites HTML code, which can help search engines better understand your content and display it in a more informative way in search results. By adding schema markup to your website, you can guide search engines in understanding your pages and content elements, which can boost your SEO results. Schema markup can be used for various types of content, such as articles, local businesses, products, recipes, and more. It can also help you claim more SERP real estate and improve your websites click-through rate. Schema markup can be generated in three different languages: microdata, RDFa, and JSON-LD, but Google recommends using JSON-LD as its less prone to user errors.
