Social Network Metadata

Facebook uses a set of specific metadata tags that can be included in an HTML document to provide information about the page.

• og:title specifies the title of the page;
• og:type specifies the type of content on the page;
• og:image specifies the URL of an image that represents the page;
• og:url specifies the URL of the page;
• og:description provides a brief description of the page.

Including these tags in an HTML document allows Facebook to correctly display a link to the page when it is shared on the platform.

Here is an example of HTML code that includes Facebook-specific metadata tags:

Twitter uses a different set of metadata tags than Facebook.

• twitter:card specifies the type of card that will be used to display the link on Twitter;
• twitter:title identifies the page's title;
• twitter:image tag, which identifies the URL of an image that represents the page.

All the other platforms may have their specific metatags.
