Schema.org is a collaborative, community-driven initiative to create, maintain, and promote a set of schemas (structured data markup) for use on the Internet. The schemas are designed to be used across a wide range of platforms and applications and help search engines understand the content of a webpage and provide rich search results.
The schemas are written in Microdata, a set of HTML tags that can be added to a webpage to provide additional information about the page’s content. For example, the Microdata tags can specify information such as the page’s title, author, date published, and more. Search engines can use this additional information to understand the page’s context and provide more accurate search results.
Schema.org includes various schemas for different types of content, including articles, books, events, reviews, and more. The schemas are designed to be flexible and extensible, so developers can add custom properties to the schemas to provide additional information about the page.
Using schema.org can help improve the visibility of a website in search results and increase click-through rates by providing rich search results such as stars rating, images, and more. It’s important to note that schema.org does not guarantee improved visibility in search results, but it can be beneficial when used with other SEO best practices.
