Structured data is a type of code added to a website that helps search engines understand the content and relationships between different elements on a page. This data is marked up in a standardized format, such as JSON-LD or Microdata, and is used to provide additional context and information about the content on a page, beyond the visible text.
By using structured data, websites can help search engines understand what their pages are about, and how the content on those pages relates to other pages and topics. This information can be used to display rich snippets or other types of enhanced search results, which can increase click-through rates and improve visibility in search results.
Some common types of structured data used in SEO include:
Schema.org: A common vocabulary used to describe web pages and their content.
Rich snippets: Enhanced search results that display additional information about a page, such as its rating, author, or product details.
Breadcrumb trails: A type of navigation element that helps users and search engines understand the structure of a website.
Sitelinks search box: A search box displayed in search results, allowing users to search within a specific website.
By using structured data, websites can provide more context and information about their content, improving visibility in search results and helping search engines better understand what their pages are about. This can ultimately lead to improved rankings and increased traffic from search engines.
