What are "schema markups"?

Schema markups are a form of structured data that can be added to a website's HTML to provide search engines with specific information about the content on the page. This additional code helps search engines like Google better understand the context and meaning of the information presented, enabling them to deliver more relevant search results. When properly implemented, schema markups can enhance a website's visibility in search engine results pages (SERPs) by allowing search engines to display rich snippets—like star ratings, product information, or event details—directly in the search results.

By utilizing schema markup, a website may have a competitive advantage, as these rich snippets can increase click-through rates and improve user engagement by providing potential visitors with more informative and appealing search results. Thus, the key reason this answer is correct lies in the function of schema markups in aiding search engines' understanding of content, which in turn can enhance a website's visibility and performance in search results.
