Why is a meta tag property og:video useful and how do you use it?

Experience Level: Mid-level
Tags: HTML Open Graph Protocol

Answer

The meta tag with an attribute property that has a value og:video defines an absolute URL of a video that points to a video that enriches your web page. The video URL will be added to the Open Graph object. The video URL is stored in a value of an attribute content.

By adding a meta tag with this property, you define an absolute URL of a video that the social networks will be able to read and display to their users.

A web page that has  Open Graph Protocol meta tags enables the page to become an open graph object. This object can then be exported to social networks or other 3rd party systems that understand Open Graph Protocol.
