Structured data is a standardized format for organizing and annotating data, such as text or HTML, in a way that makes it easier for machines to understand and process. It enables search engines, such as Google, to better understand the content of a website and how to display it in search results.
Structured data uses a specific syntax, such as JSON-LD or microdata, to define entities, properties, and relationships between them. For example, it can be used to specify the name, address, and phone number of a business, or the title, author, and publication date of a blog post.
By adding structured data to a website, website owners can improve the visibility of their content in search results, as well as make it easier for search engines to understand the content and context of a page. This can lead to improved search engine ranking and increased traffic to the website.
Examples of structured data include schema.org, a standardized format for annotating web content, and Open Graph, a protocol for describing the metadata of web pages. By using structured data, website owners can provide search engines with additional information about the content of a website, which can help to improve its visibility and relevance in search results.
