What is the function of schema markup?

Schema markup serves the important function of enhancing search engine visibility by providing detailed information about the content on a webpage. This structured data helps search engines understand the context of the content, which can lead to improved indexing and potentially higher rankings in search results.

When schema markup is implemented, it enables search engines to display rich snippets, which are visually enhanced results that provide additional information to users. This can include ratings, events, product details, and more, making search results more informative and engaging. As a result, users are more likely to click on these enhanced listings, driving more traffic to the website.

The other choices do not capture the primary role of schema markup. While aesthetics, server performance, and multimedia content are all important aspects of website management, they do not relate directly to the purpose of schema markup in the context of search engine optimization.
