What is structured data in the context of SEO?

Structured data refers to a standardized format for providing information about a page and classifying the content on that page. In the context of SEO, structured data helps search engines understand the context of the information on a webpage, making it easier for them to index and retrieve this information. This format often uses schemas in the markup provided to enhance the search engine's ability to display rich snippets, which can improve visibility and click-through rates in search results. For example, structured data can provide detailed information like ratings, reviews, events, and product prices, which can be displayed prominently in search results.

This contrasts with the other options, which do not accurately capture what structured data is. For instance, while video content may utilize structured data for video SEO, it is not a type of structured data itself. Methods for internal linking and styles of content creation focus on different aspects of website optimization and content management, rather than how data is formatted for search engines.
