What is Schema.org?

Schema.org is a collaborative initiative that provides a standardized vocabulary for structured data markup on the web. This means it offers a set of schemas, or specific tags, that web developers can use to describe types of information on their websites in a way that search engines can understand. By using Schema.org markup, website owners can enhance the visibility of their content in search results, enabling better indexing and the potential for rich snippets, which can improve click-through rates.

The main purpose of Schema.org is to create a common framework that helps ensure consistent implementation of structured data across different platforms and web technologies. This assists search engines in interpreting the content of web pages more accurately, ultimately benefiting both users and developers. Therefore, the answer that identifies Schema.org as the organization responsible for creating this standardized language and rules for structured data is accurate.
