ogtype

og:type is a metadata property of the Open Graph protocol that declares the type of object represented by a webpage. It is specified in HTML in a meta tag, for example: <meta property="og:type" content="article" />. The value of og:type informs social platforms how to interpret and render a link preview. While the simplest pages use a generic type, og:type supports a range of predefined object types, such as website, article, book, profile, and various video and music types (for instance video.movie, video.other, music.song, music.album). The most common choices are website for homepages and article for news articles or blog posts.

Some object types permit additional metadata, like article supports published_time, author, section; video types can include actor, director, duration; music types can include musician, duration. The specific set of supported types and properties can vary by platform and may evolve over time. If og:type is omitted or set to an unknown value, platforms commonly treat the page as a generic website.

og:type is typically used alongside other Open Graph properties such as og:title, og:description, og:image, and og:url to create rich link previews that appear when the page is shared on social networks. The Open Graph protocol was originally developed by Facebook to standardize how pages are represented on social graphs and is now supported by many platforms.

Choosing the appropriate og:type helps ensure that content is displayed in a way that matches its nature and can improve visibility and engagement.
