Schema markup and structured data are two distinct forms of metadata that are used to provide more meaningful context to web content. Schema markup is a type of microdata, which consists of HTML tags that are embedded within the existing HTML code on a webpage and can be used to annotate content. Structured data, on the other hand, is a more comprehensive form of metadata that involves the creation of an entire data model based on certain criteria.
